Does this switch have HTTPS?

[@TheRickJames]

Thank you for the video, I was curious about some of the QOS stuff and it answered my question. Impressive little switch for the price!

[@VanTechCorner]

Hey, thanks for the feedback and glad it was helpful! The switch can do more then what I expected. For example, with 802.1Q VLAN, I can setup a single network port PC to work as a router with this switch. Feel free to check out the link if you are interested kzbin.info/www/bejne/l6LZk3SHoqaVd7c

ax50 and sg108e both support static link aggregation. Which mean by connecting 2 rj45 cables between the 2, it will keep the connection alive when one of the 2 (rj45) cable suddenly failed/disconnected/gone? Thanks

[@xMyPlaylistx]

Hi, thanks for the review. I have a question. If you disable dhcp server on that switch while connected to the mikrotik. can you still access web interface?

[@VanTechCorner]

Hi, the switch has no DHCP server. Once you connect it to Mikrotik, it will act as DHCP client and requested for an IP address, and you can manage it with this IP address.

[@xMyPlaylistx]

@@VanTechCorner ok thanks.

Thanks , the issue i have is when i connect to my work VPN ( work from Home ) , the all network connections get disabled , is there a setting i need to change on this switch.

Does the Port-Based QoS function on this switch help with the bufferbloat in gaming? Or is the SQM in OpenWrt routers is still better when it comes to fixing bufferbloat in gaming?

[@VanTechCorner]

Hi, sorry for the late response. IMO, the Port-Based QoS in the switch should work better then the OpenWRT for plug-and-play users, unless your OpenWRT is running on high end socket / CPU. In term of control and configuration, I would go with OpenWRT. I will test it one day and update you.

[@TheRickJames]

I would actually use Port and Flow control on the switch, set the non essential ports to 100mbit and the gaming pc to unlimited or 1000mbit. Or if you have slower internet like 60mbit braodband for example set the gaming port to unlimited and the other ports to 5/10mbit

[@nassarzinho]

Nice video. It is an unmanaged switch, but you access the interface to show QoS, VLAN, etc. What is the difference for the others TP-Link that are smart or managed switch. Thanks again for the video.

[@VanTechCorner]

Hi, actually those Smart-switch as called by TP Link or Pro-switch or Netgear are all unmanaged, just that they added some L2 (OSI layer 2) features such as VLAN, multicast, LACP, etc and give it a beautiful name. There is no much difference or only a small difference in term of switching capacity, buffer size, jumbo frame, static link or dynamic link aggregation.

[@STEIN_TechGear]

I have a question about the bandwidth control. This switch can manage the bandwidth and the AP router of tp link also does have bandwidth control. But as I’ve noticed, the router gives an average speed when i set the QOS (example: I set it to 75mbps, the router speedtest gives 93mbps). Does this switch provide exact or nearest speed limit? And as I read the comments below, you said its better to config on the router end than switch, why is that?

[@VanTechCorner]

There are 2 main types of traffic: - Local traffic (from your PC to your local file server or from your media player to the NAS) - WAN traffic (traffic from your router to the Internet or from Internet to your router, for example download a ISO file from Windows server) - On your router it will be the SQM QoS where you tell the router your WAN (internet) throughput and it will make sure all connected clients have a stable connection by apply it own logic to control the packets flow or throughput of each clients, to reduce the ‘lag’ as much as possible - The QoS on the switch don’t care if it is local traffic (LAN) of WAN traffic (goes to the Internet), it will keep the throughput of the port below or the same with the value you set.

[@STEIN_TechGear]

@@VanTechCorner okay I understand the QoS of the router. But I’ve set mine to the switch to give a speed fairness for each house of my apartment. This product is so good, I manage to access it via browser on iPhone only by detecting its IP address on the main isp router, no need for PC via lan. Thank you, I have so much learnings about your videos. I’m new to networking. Hope I can explore more with the help of your videos too. Thank you very much for the informative videos.

Hello, my TP-LINK TL-SG108E 8-port seems to randomly disconnect for a few seconds every now and again, I just did plug in play and haven't touched any settings. Do you know why this could be? Thanks

[@VanTechCorner]

Hi, are you on the latest firmware? Maybe you can try to update it to the latest version and see if this improve.

[@christianjunetubera665]

Hi, does the QOS Bandwidth control limits the internet traffic only? or will it also limit the LAN traffic?

[@VanTechCorner]

Hi, the QoS will limit the throughtput of the port, it is applied to all kind of traffic.

[@christianjunetubera665]

@@VanTechCorner Thanks! What if I want only to limit the internet traffic?

[@VanTechCorner]

You will need a router with SQM/QoS function to do that (not a switch)

@@VanTechCorner alright thanks!

[@AZIMAZLAN90]

Hi Van Tech Corner. Im a newbies in this unmanaged/managed. First question is,. Cable Ethernet must plug to Pro Switch first or Router first?

[@VanTechCorner]

Hi, technically, either way is okay. However, if you are going to connect PC to your switch, the cable should be connected to the router first, and then connect to your PC with the next one. This is to make sure the PC can receive IP address from the DHCP server of the router.

[@AZIMAZLAN90]

[@portwill]

I have a modem and I want to buy a TP-Link AX10 for Wifi. I use two PCs through ethernet. I would like to segregate the Wi-Fi to IoT devices and two ethernet ports for my PCs. I think this little device can help solve this problem between the modem and router (so wifi router is port 3, PC 1 and 2 can go to Port 1 & 2). What do you think? And which VLAN setup would you recommend?

[@VanTechCorner]

Hello, could you tell me your current setup? Is it a modem or a router? But base on your need, port based VLAN should be enough.

[@portwill]

@@VanTechCorner My current setup is with a modem/router which is given by the ISP. I want to disable the router function in it and use it as a modem. Other than that I want IoT devices (security camera, light bulbs, etc) to be connected to a fully separate network to not affect sensitive PCs. One option I found is the TP-Link guest Wi-Fi which in theory can block access to the main WLAN but I am not sure if I can trust it :) The other option would be this, where I use VLANs

[@VanTechCorner]

I see, so port based VLAN will do. Just want to add that for some ISP you need to use their own device for PPPoE or DHCP or you have to set set it in bridge mode. Try to check it out first before buying the new router / switch.

[@VanTechCorner]

And yes, better I will go with VLAN rather then those guess Wifi or client isolation.

[@Mario-xs2wy]

Hi, which version TL-SG108E are you using? Thank you

[@VanTechCorner]

Hi, I am currently using firmware version 1.0.0 Build 20181120 Rel.40749. This is the updated version from the TP-Link website, not the original firmware that was shipped with the switch.

When TL-SG108 Starts for the First Time, We cannot Turn On Devices Connected to this Switch. WOL is working Once the device goes Offline after being connected to the Switch. Once we turn off the Switch and bring it back Online. WOL will not work. Usually, I encounter this in the morning. I turn on the Switch using a Smart Power Plug. But I cannot remotely turn on NAS or PC connected to this Switch. Is there any way we can avoid this issue? Firmware Version 1.0.0 Build 20220930 Rel.35985 Hardware Version TL-SG108E 6.0

Sorry I don't get what you mean. Are you having problem with WOL from LAN or from the Internet?

@@VanTechCorner From LAN, I think once the switch restarted, it doesn't know where to send the magic packets. Is there is any way to pair Mac ID to a port or something like that.

[@basharnazar5211]

Van Tech Corner So just when i enable the Monitoring i loss connection we tried my friend pc at my home so same internet

[@VanTechCorner]

Hi, the Port Mirroring function is used for data monitor / capture purpose and I suggest to turn it off, if you are just using the switch for normal usage/gaming. For example, you have an IP Phone connected to the switch port 1 and want capture the packets/call incoming & out-going from the IP Phone, then you can set up port 2 as a mirrored and connect a Voice monitor / PABX system to it.

[@mafiq8682]

My router can't see switch. What can I do? I have same but v5

[@VanTechCorner]

You can disconnect all the cable connect to the switch, only left the PC connected. Then change the IP address of the PC to 192.168.0.2 and will be able to reach the switch via 192.168.0.1

[@mafiq8682]

Hmm, you may try to reset the switch, and follow my guide again. Any network port will do the job. If it doesn't work, there is something wrong with the switch and please contact your seller for a replacement (also double check the cable)

Actually there is no much different, both of them are unmanged switch. Just that there are some features of Layer-2 Switch (in the OSI model, for example VLAN and Static Link. They have different name because of the way TP-Link and D-Link call them.

reading the options of the switch, inventing pronunciation is quite funny , like poRt has a R in the middle. you're reading all the time pot, instead of port, i.e. the first one is something to smoke. do not omit letters and learn the correct pronunciation .... your video is as helpful as reading the manual in Chinese ....
