When coming from builds before openwrt/openwrt@050621a you will need to flash the installer again, ie.
sysupgrade -F https://github.com/dangowrt/linksys-e8450-openwrt-installer/releases/download/v0.5.3/openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery-installer.itb
This is because the SPI-NAND driver has been replaced and the new driver is very picky...

Hi,
after updating I also ran into the issue of the 5GHz radio not being found, but at least it was listed as not active. I tried the step above, however it isn't displayed at all afterwards. I suspect this is because I didn't retain any settings.
Is there a way to do a full start-over with the installation that would bring back the radio?
Please let me know if I need to provide any logs, and ideally where to find them.
Thank you!

Hello,
I am having this same issue. I have attempted the above fix with versions 0.5.3, 0.6.0, and 0.6.1 with no luck. I have tried both with and without retaining settings.
When running iwinfo I only see the 802.11bgn radio.

Is there another solution that I am missing? I am happy to provide any logs or command output to help troubleshooting.
Thank you for your time!

While in recovery mode, mt7915e driver is not present, only the mt7622's builtin radio is detected.
Pleasedo try out with latest installer version and use a standard squashfs sysupgrade image for ubi layout. The mt7915e radio should be detected in that case.

May you send your dmesg and the output of the “lspci” command?

Please share the output of lsmod command and make sure the mt7915e module appears there. If not, then for some reason the driver is not installed in the image you are using. Using the sysupgrade image downloadable here should fix that.
Another reason could be that the calibration data was not fixed up (it should have been by re-running the installer). To validate that, please try
hexdump -C /dev/mtd2
and share that here so we can see what's going on.

It does not appear that mt7915e is showing up. I will try the sysupgrade again and report back.

mtd2 looks good, so that worked and is not the problem.
Did dmesg output change since now the module at least got loaded (it should also show us something in the kernel log, dmesg | grep mt7915 should tell)?
And does iw list show the 5 GHz interface?
If you kept your previous configuration while doing sysupgrade? If so (and as your previous image was apparently somehow broken), try resetting configuration using firstboot.
As the driver was completely missing in the image you were running before: where did that came from? Was that a local build you compiled yourself?

I am uncertain which image I had last flashed. It was either one of 0.5.3, 0.6.0, and 0.6.1 or the most recent snapshot from openwrt. Retrieved from https://firmware-selector.openwrt.org/?version=SNAPSHOT&target=mediatek%2Fmt7622&id=linksys_e8450-ubi
It appears that firstboot did not help and seems to have broken something in LuCI as the wireless page will now not load.

It appears I have fixed the problem. After running firstboot there were some issues with LuCI. To resolve these problems I re-flashed the most recent recovery installer and sysupgrade. After this the radio reappeared and seems to be working as normal.
Sorry I don't seem to have anything more useful.

commented on June 9, 2024
Did you ever re-run the installer before? Because this was needed (scroll up in this issue ticket) to overcome problems with broken OOB data as the installer (from v0.5.3 on) would re-write the factory partition in order to fix that. I'm asking because I'm still seeing those errors in dmesg
blk_update_request: I/O error, dev mtdblock2,
So that looks like you never fixed OOB data (ie. you just used sysupgrade image and never re-run the installer after v0.5.3) and it may work now due to the mt7915e wifi driver being more tolerant with this kinda situations after openwrt/mt76@25237b1 and openwrt/mt76@71e0847 .

I had re-run the installer previously. However, I believe that something had gotten corrupted on my hardware before attempting to update my firmware (I was experiencing unexpected behavior which caused me to attempt the update). I believe something was not being properly reset when running the installer that was resolved by running firstboot causing the subsequent install to correctly complete.
