I'm having difficulty with a new MR90x. I went through the intallation instructions, appearing to work quite fine until step 15. Following a reboot, the device seems to be booting into the u-boot recovery option, providing web access to upload firmware only. Attempting to upload the OEM bin firmware file reports to be successful, but then I'm straight back to the same recovery stage after a powercycle.
So now I'm trying to recover the device without having to solder in the serial connectors.
Judging by how quick the upload part of the recovery firmware upload goes (about 5 seconds), could it be the OEM firmware is not being uploaded correctly? Is there anything else I can try to recover the device?
Edit: Never mind. I ended up going the serial port route (and boy is it touch to open). Somehow one partition got corrupted, throwing many ubi read errors (error -74). The other partition is fine, and I've been able to install via serial onto that. I'll try fixing the other partition later.
I vaguely remeber that my initial recovery test also went blazing fast, to me the observed 5 seconds don‘t seem overly unusual.
(My other mt7621 devices take over a minute to flash via recovery in comparison)
in case anyone is looking for sysupgrade feedback:
for me the regular sysupgrade (which does not keep custom packages) from 23.05rc3 to 23.05.0 (+checkmarked, to retain config) worked without issues (so far).
not a good omen regarding availability: amazon de no longer has it listed. Though it was just 3 month ago, when it was first listed there. Other German onlineshops never had it the last months.
Could be, it stays a rare niche device. Maybe the chip shortage is still going on.
A quick scan shows iponshop de and iponshop at have it, but I don't know this vendor at all or whether that is trustworthy, so stay cautious, it is up to you to decide, where to order safely.
My general recommendation is: first check the https://openwrt.org/toh/views/toh_available_16128_ax-wifi list, if any other device with the same mediatek mt7981 chip or another supported AX device looks decent enough for you to buy and is available in a shop near you, before starting cross-country purchasing adventures for rare devices.
Maybe check back on amazon de in 2-3 weeks, maybe miracles happen and they get a new batch.
I tend to say, something could be wrong on my side.
mine currently shows:
Hm, there should be a kernel partition of 9 MB as well in the beginning of the 32MB of the UBI partition, I currently don't get, why mine shows 32MB free space, if the UBI partition is also just 32MB. ...I might need to investigate mine the next days.
I would not be worried from your perspective. Without knowing details, my gut feeling says, yours looks more correct than mine at this point.
(I've installed mine via SSH, not via serial cable)
Can I ask what behaviour you were seeing when trying to repair with stock install? I am getting a 100% upload, on the manufacturer's recovery page, and a success message, but then when I go to reboot, I get nothing unless I reboot back into the recovery mode.
Anyone have any ideas about how this happened, or how I might fix this in software?
Orient me on the wifi settings in OpenWrt (23.05.0): the network adapter (intel ax201) in Windows connects to the router via wifi6 at a maximum speed of 1.7Gb/s, but with stock firmware it connects in two streams - 2.4Gb/s.
It turned out that intel wifi adapters have regional restrictions Intel LAR/DRS, so my adapter was periodically connected to the router according to the 802.11ac standard instead of 802.11ax. The problem was solved by replacing the driver.
