Great work guys, thanks.

I minor remark, the links are not updated in the Table of Hardware: Firmware downloads. At least not for the TP-Link TL-MR3420 V5

I found the 21.02.2 firmware version in here:

I will take a look later this day.


Congrats on the big release, some great fixes included here. Sticking with a Master snapshot on my WRT32X for now have 75 day uptime.

Support for the RAXE500

Wait, this is a high end WiFi 6E router, is this a typo?

Excellent news! Upgraded my WRT1900ACS V1 and my WAC104 from 21.02.1. No issues.

Developers: Well done and much appreciation.

Hi all....many thanx for hard work....Can i just flash this and keep settings?

Hi all.
Successfully installed 21.02.2 on these devices by sysupgrading from 21.02.1

  • Netgear WNDR3700v2 (ath79 generic)
  • Netgear WNDR3700v4 (ath79 nand)
  • Netgear R6220 (mt7621)

Successfully installed 21.02.2 on these devices by flashing factory image after reversing to Linksys firmware.

  • Linksys EA7300v2 (mt7621)
  • Linksys MR8300v1.1 (ipq40xx generic)

and of course on a tiny PC

  • x86/64

Thank you to everyone who contributed.


It does look as though things are taking time to filter through. The site home page is still showing 21.02.1 as the current stable version. I have found the correct firmware files, working from this thread, but I can't blame anyone for waiting a few more hours.

Reading the notes is a good idea.

Updated my TP-Link TL-MR3420 V5 and every thing seems fine.

One observation, I needed to re-install openvpn package even though I asked it to keep the config.
Maybe that is how it works, I'm new to openwrt.

Yes, I usually wait for the mailing list announcement, too, as an indicator, but that hasn't happened yet either. Still, a week on, it's clearly out regardless of these details.

That's expected behavior if you don't use this service.

I updated my Linksys WRT3200ACM, and it has been working fine. It's great to have an official patch for the wifi issue that was affecting the platform.

Thanks for the developers for all the work that goes into doing a release!


Thank you to everyone for your hard work!

Happy to report sysupgrade of c2600 from 21.02.1 => 21.02.2 (keeping settings) OK.
Good job :scream_cat: to all involved!

This announcement was not sent to the openwrt-announce mailing list.


Whenever I try to sysupgrade to 21.02.2 my r7800 just reboots into 21.02.1. Anyone have an idea why?

fixed: reset the router and tried again

Thank you all! one question, to upgrade a mt7621 device, zbt link 1326, from 19.07.7 , do I need factory or sysupgrade image?

Factory is usually only required if vendor firmware "from the factory" is still running.
