2 Routers 1 Home Network | Why Disable DHCP?

When you have 2 routers on 1 home network, is it really necessary to disable DHCP?
"I didn't disable DHCP on mine and it worked fine!"
Yes, it's true that it's not necessary to disable DHCP. Dynamic Host Configuration Protocol's whole purpose is to assign IP addresses to devices on your network. But if you don't disable it, you will have problems in the future.
Router 1 has a DHCP server that operates INDEPENDENTLY of Router 2, which also has its own DHCP server. They don't communicate with each other which IP addresses they are handing out.
It's possible that Router 1 can assign DIFFERENT IP addresses than Router 2. It's random.
However, it's also possible Router 1 can assign the SAME IP addresses as Router 2.
You can even plug everything in and have it working initially with no IP conflicts. But then later when you get back home from work you can be assigned a NEW IP address without even realizing it. So it's possible to have problems in the future even if you aren't adding "new" devices to your network. Your IP address is LEASED to your device from the DHCP server for a temporary amount of time. Like 1 day or 1 week. Then when that expires, it CAN be assigned the same IP address again. But it can ALSO be assigned a different IP address. This opens up the possibility for IP address conflicts days, weeks, or months down the road.
It is possible to make advanced configurations to your DHCP servers so that they are choosing different IP addresses independently so there will be no IP conflicts. But I believe in the KISS principle (Keep It Simple, Stupid). Just disable 1 of the DHCP servers. No need to make all kinds of configurations that achieve the same result as simply disabling DHCP on all but one router.
All devices that connect to the router with DHCP disabled can still obtain an IP address from the router with DHCP enabled. Basic networking concepts allow that to happen.
I hope this was clear and not more confusing. Thank you for your time and I hope I've helped you out!

You don't how happy i am to have found your channel. Thank the heaveeeeens 😌♥️

[@SriTejaChilakapati]

Me at 7:21. So that's how a switch works! Believe me I learnt more about switch by watching this video rather than plenty others in youtube. Because apparantly nobody ever told me how a switch works in combination with a router. All they told was a router has DHCP where as a switch doesn't. This video gave me the complete idea. Thanks! This helped me a lot.

[@edwardreilly9098]

Finally - someone explains why the secondary router should be set up in AP mode with DHCP turned off. Thank you very much.

[@richievellalar3214]

you can split the ip address , where no issue

[@Humanist1199]

This man is genius in explaining complex things..appreciated

[@ruvelcuasito6848]

Man, you're totally one of those people who's effective in teaching... cuz a guy like me, who had no clue of this DHCP and other router terminologies etc., finally understood this sh** by only just watching this 10 min video of yours. 1 sub count from me? done.

[@neoone75]

Thank you for your explanation. I used to be a network and server administrator some 20 years ago. Since then I have been doing other stuff in ICT, more business architecture orientated. I have forgot all the skills I used to have. I'm going to move the new apartment in couple of days. Because of two stairs I need to have two wifi routers and I simply didn't remember how connect them together in right way.

[@richievellalar3214]

how come you forgot that mate?

[@SamNjorogeOmweri]

Thank you so much, this is the best explanation of conflicts that I’ve received so far, was trying to figure out why my phone would just not work sometimes on Wi-Fi.

[@avtech6056]

Short & Clear. Well done

[@bradakan1]

A friend told me to do this, i wanted to know why. And this is a clear video with the info!

[@XxinsaneDavidxX]

Thanks ! Straight to the point , easy to understand ✅

[@1slothua1]

Great explanation. I set up a google Wi-Fi nest and noticed my phone’s internet connection was always slow. Now I know why. I will disable my cable modem’s DHCP. Thanks

[@wagonet]

This man can explain complex topics and simplify it for the regular peeps. Thanks!! This helped me a lot

[@unknownwolf4046]

This odd my 4G modem it keeps disabling DHCP i have no External Router hooked to it my bec 6300nel Ridgewave R15 LTE modem

[@codycarr4608]

Man love how you explain it for us network dummies can understand it! Lol Thanks man been having this exact problem! 😆

[@ProducerCliff]

Absolutely brilliant explanation! the best on KZbin!

[@rugman0462]

Very clear and very simple explanation thank you for you help and instruction Keep it simple !

[@TheRafalblog]

What you have said is common sense. The best solution is always to keep things simple. I have a couple of routers at home. The nightmare was setting up all the routers the other ways you have mentioned: setting up the IP ranges etc. Since I saw your other movie about how to set up routers disabling DHCP and changing IPs in every one of the routers, life has become easier.

[@catmar1944]

Yes that was very helpful as we have two routers here and we had conflicts, so hopefully when my son in law gets home from work he can disable DHCP on the secondary router, so thanks for the clarity.

[@Salil616]

Omg what a great teacher you are❤️❤️❤️

[@UltimateTechHub]

I did a similar video and yes disable DHCP because it may or may not work and why take the chance. Its a simple one click disable tab. Its not a difficult task and its the same as disabling the UPNP which is also necessary. Good video Home Network Central. By the way I love Home Networking!!

[@3015gaurav]

Life saving video... huge kudos to maker...

[@MikeSmitran]

Finally the right information, Thanks man !!!!

[@HomeNetworkCentral]

Glad to help!

[@ahmedalmassri2997]

Really excellent explanation Very easy very simple and informative Thanks a lot for great efforts

[@BIG_JV]

That explanation was FANTASTIC! thank you brother! 👍

[@chuizeng8727]

I found the major issues with multiple DHCPs at different routers are the resources sharing, such as printers, NASs, they won't able to cross all the routers. IP conflict is not really a issue as you can assign different IP ranges for each router/DHCP.

[@TurboSpeedWiFi]

You can but the issue is that most people will not do that and you will get IP conflicts.

[@Kardouino]

Yes the different ip ranges for each router/ dhcp is the solution

[@lilcrazyj0sh]

Have one router on 192.168.1.x and the other on 192.168.0.x

[@harshitsukhija9626]

Thanku soo much for providing me this information. I m not able to use the internet for 5 long hours. Now I get my solution. Thanku soo much buddy 🥳

[@carlosmontana5219]

I just subscribed this dude is a beast explained everything in a couple minutes and he is right

[@guillermoe.sanchezguaida3787]

I think I got that problem with my Echo Dot and my sister's Echo Dot, thanks for the video man

[@HomeNetworkCentral]

No problem 👍

[@yunoshi9012]

Very well explained. Thanks for this

[@Weowndayou]

Thank you for the explanation!

[@paribeshpaudyel]

Your explanation is awesome. I like your explanation.

[@carlosmontana5219]

This guy is a beast he knows his shit i get calls with other ITs i explain this and they are lost, when i get calls with ITs like you i love it yall understand this my calls are done within 20 min tops, ITs that dont we will be hours on the phone and nothing i start thinking this ITs are ripping off their customers is not that hard but this guy knows his shit

[@Kiran-Rai]

Liked it how he explained...!!!

[@tushar.bhavsar]

Sir you are legend for me. I was looking this from long time.

[@aden1319]

why this channel just appeared today :( this was detailed, now i understand now .. thank you so much ..

[@SSS-dd1um]

Nicely and well explained.

[@sps6470]

Best explaination on KZbin

[@dolandoxclub1730]

hey look, we want a lan party but it doesnt show us on the same network. yeah i didnt need youtube to explain this to people, but its finally nice to explain if your stranded in the middle of nowhere with too many computers, this is always good to know.

[@ykhanpathan7566]

Thanks sir today my all confusion about DHCP you cleared that thank you so much sir.

[@Sound_man73_Electronics]

Excellent video. Perfectly explains which DHCP setting to use for an access point. Thanks!

[@ramialmeshal8995]

thanks for the perfect explanation.

[@saadasarali]

Very good explanation one video with the very good information no other parts very good.

[@Dean-vd5wr]

Hi great video, but not sure if I missed it in the tutorial. Whether the ethernet cored has to stay connected to each router that you add after configuring? Or can they be wifi connected to the home router? Thanks Dean.

[@carlosmontana5219]

Thats goooooood man i wish it and techs knew this, isp will put in passthrough or disable that but no one understands other router settings

[@charlymendoza5109]

Thank you for the best explanation sir

[@barbierimando8133]

another question.. can the internet provider monitor and change the configurations i made in the routers on their end?

[@back2basics512]

Your video make people understand better and clearly, can i request a video see that you a good teacher, the video i want you to make is to add unify ap the roof mounted to to the network with it's configuration and also how to access the access point remotely as i think the other guy's are skipping details

[@TECKTECHBones]

very well explained, now let's say I have 2 routers connected but I want to use full time VPN configuration on one of them what do you think should be done with dhcp? keep both of them open because although they are on the same network , the VPN permanent one will be forwarding all his traffic through a virtual network so that they will not be ip conflicts?

[@_h_e_r_0_]

Thanks man, it helped me a lot

[@DeepakBhat]

perfect explanation

[@bahamiandjcue6687]

thanks bro this video was super helpful

[@HomeNetworkCentral]

Thank you for commenting!

[@wiliamabbey9365]

Thank you 😊 you are the man 👨

[@AmirKarki]

Great information

[@LTVoyager]

If you connect LAN from primary to WAN on secondary, that will create two LANs and also avoid the issue, correct? However, I believe that will prevent devices on one router from accessing those on the other since they are in different subsets, right?

[@lohti6399]

I connected 3 routers together and wonder if I should disable dhcp server on 2nd and 3rd router. This video explains that I should disable dhcp for my other routers. Thanks

[@truuBludd]

Bruh, me.again. Just to let u kno, I just subscribed, your vids are informative and you solved my first issue fantastically. Would you consider doing a vid on setting up VPN client on a secondary router. Team HOME NETWORK CENTRAL!!!💥🙋🏼💥

[@MarcelloLins]

Fantastic explanation. As far as I'm aware it is common for ISP modem/routers to have DHCP servers you can't disable. In these cases I'm guessing you should always disable DHCP on your custom router (non ISP) and leave the one on the ISP router enabled.

[@WimBlijstra]

Thx, keep it simple

[@marcrm02888]

Nice job! I bought a new router and want to add it to my too old Verizon FiOs modem/router to get a better wi fi signal. I'll check out the disable dchp video for help. thanks again.

[@celotlcoatl]

Hello, this is a great video thanks! You have a new subscriber! Questions… 1.- Can you connect several clients to the secondary router as well? 2.- Can you see the clients connected on the secondary router while in the network map of the secondary router? 3.- Can you set parental controls, firewall, vpn on the secondary router.

[@HablaKK]

Answers: #1 YES, #2 d second router will function in bridge mode or like a repeater via cable or wifi, #3 NO, all configuration go to router #1, except when you create a new wifi password and wifi name for router #2.

[@brierepooc8987]

I have two networks in my house running on two different segments with DHCP running on both routers. But I segmented my network, one for my virtual network home lab and one for my family.

[@deanlor17]

Thank you, solved my problem :D

[@gregtyler4002]

Tyvm!

[@bezandros]

Thank you for making a thorough and well explained video, I was able to fully understand how DHCP works. I have a question thought. When i disable DHCP on my second router and connect it to the network i cant seem to be able to configure it by entering its local ip address anymore. I suppose it got assigned an ip from the DHCP server on the main router?? if so how can i find the second router ip and configure it (e.g change the ssid name and password)

[@TurboSpeedWiFi]

log into your main router and view its DHCP leases. Then look for your second router in the list and write down the IP address. From there navigate to that IP address to configure your second router.

[@axelpropro]

Thanks for the follow up video. My question is on another video I watched they kept it enabled and changed the Channels on it where it doesn’t not interfere with each other such as taking Channel off auto and putting it on 1 and the other one being on Channel 11. What is the best option ? I know you mention the KISS method but just curious if there is any benefit to doing it either way? Thanks

[@HomeNetworkCentral]

The channel configuration you're talking about doesn't affect the IP addresses. That will help with interference between the 2 routers WiFi signals. Even on different WiFi channels both routers will be on the same IP network. But changing the channels like that is kind of similar to the IP address DHCP server idea. You don't NEED to do that. it's possible both routers could pick different channels automatically. but it's also possible they could automatically pick the same channel. if you manually check them and find that they're interfering with each other then it might be a good idea to set their channels manually. But again the channel thing is completely separate from the DHCP server. Thanks for the question!

[@SantomPh]

is disabling the older router a better option? I have a modem/router combo that is aging badly and have been advised to get a newer router for faster speeds. I still need to modem half of the combo , so how do I run the internet through the modem (with router disabled) and then through the new router? what do I need to do to disable the router function on the old combo with the Wifi running through the second router?

[@ismailif597]

but what if i want to enable DHCP in the other router with deferent network so that each routers manage it own devices can i do that ? any help pls

[@lilskely6278]

thank you for explaining dhcp to me i had two routers interfering with each other and had issues at playing games wireless and on cable (ethernet) now one is dhcp enabled as the main router and the other one corresponds with the main one, i can use it to play airlink in my quest 2 without any issues.

[@user-np4bg2rm1j]

Hey love the video, was hoping you can help. I have two of the same ont routers from my isp. ( One was from moving to a new apartment). My main router is connected to the ont and the secondary router is connected to the main router via lan. I only get internet access from the secondary router when the dhcp is enabled but it doesn't work well and loses internet access. When dhcp is disabled in the secondary router I'm then unable to connect to the wifi.

[@mariellad]

Thanks for this! Can you tell me if I have to take care to use similar modems? For example, we're in Australia and we have the NBN which is a broadband. Do I need the second modem to be broadband compatible? Or can I use an old ADSL modem?

[@HomeNetworkCentral]

If you have 2 separate internet connections coming into your home, the modem just need to work for each technology. But no they both do not need to match. You need a cable modem for the cable connection, DSL modem for the DSL connection, etc.

[@math001]

Will there be any delay if I plug into router 2 instead of the modem/router provided by the ISP or is it negligible? I'm planning on having this setup because apparently the firewall in my ISP router does not work. I want to hide my PC behind a 2nd router with a functioning firewall. Was supposed to go and use bridge mode for the ISP router/modem but for some reason it throttles the speed when doing that so I was looking for alternatives. If I'm understanding this right I can do something like this for my computer: ISP > Modem/Router (DHCP On) lan port > lan port Router 2 (DHCP On, Firewall On) lan port > Device

[@carlosmontana5219]

You a goood tech or IT for this video, some do passthrough some bridgemode but people dont understand that

[@marilouferrer9328]

Hii! Just found your channel :) questions, if I extend my WiFi to another house using cables and the same type modem router, can I have diff passwords each and will I still be required to disable DPHS? thank you in advance 😊

[@gurdeepgss]

so we shouldn’t have any problem if wireless is disabled on one and we only connect to second with wireless or wired without disabling any dhcp servers?

[@darksaberopgaming5907]

awesome video just what i was looking for but i got questions regarding secondary router so basicaly on main router i have multiple devices connected including secondary router which has few devices connected to it , problem is i that get random disconnetions, all my devices ip’s including secondary router are within 2 to 49 dhcp range on main router than i have setup dhcp range start point from 50 to 250 to avoid conflicts and disconnection but i still get disconnected randomly so should secondary router be within 2 to 50 range on main router or from 50 to 250 range and its dhcp set from 52 to 250 thanks in advance

[@johnpaulgavina9209]

This is awesome.

Dude! You're speaking my language. Insta-subbed.

[@hungrynapps]

What if I had my connection lan to wan? .. should I disable dhcp on router 1 or 2

[@Dobemandan]

Would the wired ports on the back of the main modem/router still work in bridged mode?

[@mandarjoshi9252]

What if we add a network switch between the two routers? For example, I have two routers connected thru switch. * My Modem is connected to Main Router. * From my Main Router, I have a connection to Unmanaged Network Switch. * From the Network Switch, I have connection to my Second Router. Do I need to disable DHCP on second router? If I disable DHCP on my Second Router then I don't get internet connection thru the Second Router.

[@needheartranken]

Hey! I hope you respond to me! Why does my VOIP avaya, i work as call center agent, doesn’t work with a static IP router? It just can’t log in. And I’m planning to buy another router and set it to DHCP but I dont think it will solve the problem

[@punjabistar1998]

thank you very much for the information love from India ❤

[@emmagilbert9662]

great, thanks

[@BreakTime10101]

So can I assign certain items to one router and certain other items to the other router, or could I have one router do 2.4ghz and the other do 5ghz?

[@meetsheladiya6114]

thank you for making this video, I searched for this answer and counldn't find it anywhere until this video

[@jasonmamma3332]

Great video, thank you so much.i just have one question (I'm still in school so I'm still learning). What happens when you disable it on both modems? (Is it even possible)

[@jamesalberttribiana9957]

good day Sir, can i still use the LAN ports on router #2 to connect a cable to a desktop?

[@Droneoflife]

Thank you for a great video, really good explanation. I have a problem though, i was hoping you could point me in the right direction. I have set up two routers like you have showed, lan to lan, and i disabled the dhcp on my primary router and have it enabled on router number 2. But it seems like if I reconnect a device to my network it won't get internet access unless i set a static ip. What could cause this problem?

[@plopli2009]

Primary router shoud have dhcp enabled and secondary disabled.

[@md.al-aminifti7194]

Thankx a lot

[@shubhamthoke7116]

Please help me Sir! When power goes off primary router shuts down and when power comes in 2nd router which I had bridged need to be configured again. Please help me out with this problem. I need to configure all the settings again and again to bridge my 2nd router.

[@dennisg1999]

What if I wanted to set up a second router out of range of the first (a very long cable to another building with lots of brick in-between)? Could I just connect them LAN -> WAN and be done with it? As one service is dropped it picks up the other? Or is the issue still present?

[@TurboSpeedWiFi]

You will still want to set it up like in the video. The distance makes no difference.

[@ylric4274]

Hello I can't access the admin rights of the main router but I can access the admin for the second router. I think the main router has DHCP and default settings, can I do this without changing anything from the main router?

[@rcarl210]

Great video! What are some symptoms of an IP address conflict in networks that have two competing DHCP servers?

[@TurboSpeedWiFi]

You will see devices that drop their connections randomly. On some devices including Windows you will get an IP conflict message popup on your screen.

[@abdullahsaif9196]

Slow speed frequent disconnection

[@edwardreilly9098]

Envision a conference room with two wifi routers with DHCP enabled on both. With two people in the conference room - connected to the Wifi lan - it might work. Now take that same conference room when the entire sales team is meeting and now you have 25-30 people with laptops and iPhones trying to connect to LAN. The IP address conflicts will escalate and it will appear as a limitation to max users - as users get bumped over the lan. But the reality is this dual DHCP IP address assignment. Then cure is to set one router as a Ap (which disables DHCP function) and then all can join harmoniously.

[@arlarla]

can i still use dynamic ip on access point rather dan static ip and turn off the dhcp settings?

[@abdulelahx5482]

god bless you 👍🏻
