OpenWRT - Install OpenWRT 21.02 on Mikrotik RB750Gr3

[@izrailmoiseevic2844]

Thank you for that clear instruction! One IMPORTANT note: Sometimes its impossible to setup latest version of OpenWRT and you need to try older version. You didn't see any errors. Logs in TinyPXE will looks fine and when you change port from 1 to 2 you can't reach address 192.168.1.1. So in that case take older version of openwrt. Also you can try other subversion of RouterOS v6.xx

[@RavingMad]

I'd never flash a MikroTik product with OpenWRT, despite the fact that I love using it as much as RouterOS. The reason is the motivation for me to move out of standard consumer grade stuff in the first place. I got tired of perfectly good hardware losing updates, lacking performance, getting bricked by official firmware, and hardware getting EoL and deprecated despite being powerful enough for my use case. Secondly the fact that the stock firmware wouldn't allow me to take full advantage of the hardware. Both RouterOS and OpenWRT solves these problems for me. Both have life long updates and both let me get as much as I can (to the best of my abilities) out of the hardwares. As such if RouterOS is already there, I don't see any value in switching it out for OpenWRT. Love the video regardless, because love the endless possibilities with both platforms.

[@VanTechCorner]

Totally agree. I have been using Mikrotik boards in production environment and there is no point to complain about its performance (even though there are still small bugs). However, as a channel making videos about OpenWRT, I want to try all the possibilities and see how Open-Source working with a board/system made for Closed-Source. I belive there are people who is having the same idea with me and perhaps searching for the same thing on Google (like what I did previously), that is why this video come.

OpenWRT allows you to write your own apps, doesn't it? RouterOS doesn't. That's an advantage

[@RavingMad]

@@VanTechCorner I appreciate all your videos, and they've provided with some good fundamentals in OpenWRT. In my network for routing and managed switching, I have 90% MikroTik, but for APs I strictly use OpenWRT. This combination has been working great for me so far. Most amazing thing that has happened since my network transformation to present state, is that I don't have any unplanned downtime. Sometimes if I didn't upgrade firmware, the setup runs for months until I finally get around to rolling out the upgrades.

[@RavingMad]

@ Yes of course OpenWRT is open and OSS so it provides a degree of freedom that MikroTik won't. But I mentioned my original motivation, I don't want to stop receiving updates for a perfectly good working hardware. I understand if hardware doesn't have enough resources to perform actions but I don't want them to be deprecated because vendor released a new product and they don't want to support the old working hardware anymore. Both MikroTik and OpenWRT ticks this box. On the other hand... MikroTik has scripting built in and in version 7 of RouterOS they have container support. I think these two features allow one to greatly augment RouterOS functionality. Regarding this particular model, Hex, the device only has 16MB flash. Unless one builds their own image, with pre-built OpenWRT images, there isn't much space left for a whole lot of new stuff.

Heh, HEX has also micro SD card slot

[@ckthmpson]

I have one of these routers (the Mikrotik RB750Gr3 HEX) and have been considering flashing OpenWRT. I bought this router because I thought there was support for Zerotier on Mikrotik. However, turns out this is only true for the Miktrotik ARM based routers...not the mmips (Mediatech) based Mikrotik routers. I've since switched from Zerotier to Tailscale, but still no way to run either (Zerotier or Tailscale) on a Mikrotik RB750Gr3 when it's running RouterOS. Hoping that with OpenWRT, I can have either Zerotier or Tailscale running on the device. Very good video. Thank you for sharing...

[@VanTechCorner]

Cool. Thanks for sharing another reason to use OpenWrt on this RB750Gr3.

[@KomentarAna]

What benefit or advantage OpenWrt than mikrotik?

[@Pesonkmamen]

Waiting answer

[@gingerbladebl]

What’s advantages of openwrt vs router os? Router OS imho is way more powerful than openwrt, despite all the complexities but it also comes with a lot of functionality (yes, some of it are proprietary. I have installed openwrt before but not so impressed despite easy configuration in the beginning but not much use later on.

[@joashly]

Personally I don't see the great advantage of OpenWRT in a mikrotik Router, Mikrotik has a thousand times more functions than said OpenWRT. Personally, it is a bet that I would never do it. MIKROTIK FOREVER...

[@gingerbladebl]

@@joashly Thousandly agree man!

[@coretube3206]

Openwrt mean freedom of wireless! This word can win!!!

[@speed_rider362]

Well, I have some issues with RouterOS. It has tons of functionality but some functions do not work well together or are unstable (Wireguard, some seetings in VLANs). Also, with OpenWRT I have better performance. When I put 15 users on wifi on RB951G-2HnD with RouterOS, internet is unusable - pages do not want to load (no SQM, 50 MBit). 15 people on the same router with OpenWrt can browse the internet fine (again, no SQM, 50 MBit link).

[@Theflow55]

I have done everything but when I turn off the router and turn it on again, routerOs appears again, it deletes the openwrt

[@orfeous]

What are the usb port supposed to be used for? Theres nothing about it in documentation. What does the mode button do? Nothing on that in documentation as well

[@VanTechCorner]

Well, in OpenWrt, the USB port can be used to connect anything has a USB interface, such as a USB 4G modem, a USB WiFi adapter, a printer, a USB stick, USB HDD ...You can also connect your iPhone/Android phone to it to use the cellular data. There are different things you can do with the USB port, the same go to the button. It is not limited like what you can do in RouterOS. OpenWrt is open-source, the information (the wiki) is contributed by developers and users (like you). For sure there will be something not found in that wiki, but it doesn't you can't find it somewhere else. Let's say, the user manual of the Laptop will not tell you what you can do with the USB port, but you will know what to do and how to use it.

[@ashrafkhaleelibrahim3340]

Great as usual, thanks By the way, does the openwrt wifi range similar to the factory firmware?

[@TheBlackBOXMX]

this device doesnt have wifi.

[@elenciomukaj]

Hi, after running the openwrt i can enter the interface, after uploading the flash file the router reboots and i cant access it anymore, no LAN lights power, only power and usr . I can redoo the process but anytime i flash the frimware the router wont work. Mikrotik RB952ui

[@elenciomukaj]

Update : To make it work , every time i turn off (reboot) router i have to reset it with the button , after the reset the router will boot up and openwrt interface will open . I have to repeat this step every time the router is shut down. Any ideas what to see or config ?

[@LouiseBrooksBob]

Very useful, thanks! It would be nice to know if this router's hardware support for IPSEC VPN tunnel encryption is available with DD-WRT.

What if i have a configuration VPN, users, RADIUS etc on microtik can i use it on openwrt? Or i must do it again?

I need to do the same step if I want to revert back to stock mikrotik firmware?

To go back to RouterOS, you just need to follow the netinstall procedure, which is available at Mikrotik website.

Dude, thanks for you work, but why the hell do you use Openwrt if Mikrotik router os is a powerfull software??

Hey, there are lot of things OpenWRT can do and RouterOS can't, and vice versa. For example, before ROS7, Wireguard is not supported. Also, OpenVPN is not fully working on ROS7. Other Linux packages, such as nut-server (network ups tool), pi-hole, adguard home are not running on ROS. But when the same device running OpenWRT, I can configure it easily. If you take a look, the video is reaching 50K views. This shows that a lot of viewers find the video useful, or they are curios, or have the same thinking but want to see what is the out come.

Hi, I already did some videos with x86 and you can find them in the OpenWRT tutorial playlist (on the channel homepage).
