I have a Linksys WRT32X router, have been using it for a few years with OpenWRT 19.x
But now I need OpenVPN 2.5.x so I decided to update my OpenWRT.
First I tried openwrt-21.02.0-mvebu-cortexa9-linksys_wrt32x-squashfs-sysupgrade.bin
But saw a warning message that this version cannot be used to update 19.x and I have to use a factory.
So I flsahed openwrt-21.02.0-mvebu-cortexa9-linksys_wrt32x-squashfs-factory.img without settings saving.
And at first glance, everything works fine, but after 5-10 minutes it starts to glitch.
Unable to open LUCI, devices connected via Wi-Fi cannot access the Internet. The Internet still works through the local network.
Etc..
I have this disabled (now) but connecting to sites or downloading singular images on sites kind of randomly fails. It's really weird because the wifi is stable and connected and it seems for that particular site / image on the site. Not really sure what is going on.
Disabling of WPA3 (802.11w) does not help, its glitching in unpredictable way, now even DHCP and internet on LAN does not works after some time of working.
There is not a lot the dev team can do!
The wifi driver is essentially abandoware.....solution is probably to use a business grade WiFi AP for your WiFi, you can pick them up surprisingly cheaply on eBay
