Malware damaging ASUS routers?

[iFrogMac]

I did, I've never seen previously in my router channels 149 upwards, I won't use them and call it a day

Sounds good, you might want to also check to see if your regulations have changed so you won't be limiting yourself unnecessarily going forward, if you're now able to legally use them.

I thought the UK regulations were the same as the EU.

No they're different slightly now.

I've had UNII-3 channels as long as I can remember. I am getting on a bit now though.

You previously stated that you only have those additional channels because you've modified the nvram variables to get them.

That totally slipped my mind. You remember that?
No, this is a different router. Messing with nvram totally screwed the router up.
*edit* I've been back and edited.

Well, I don't what Asus did, but my router is now illegal in europe:

149 Band is forbidden in UE

Interesting first report! Given ASUS firmware, maybe their fix overlooked something. Or maybe your particular router was/is not in its proper market, thanks to globalization or stressed/crossed/corrupt supply chains.

The problem is solved by 50%
Wi-Fi works
The router is restored from the template in the firmware
A fake MAC address is generated
PIN code 12345670
Region of a non-existent country YY/20
Debug mode is disabled, this is important

I would suggest that all damaged devices be set to the territorial region AA/02 - mainland China, but there is a menu for selecting regions and among them are the USA, Europe and Asia

MAC address should be looked for here

cat /proc/nvram/BaseMacAddr
cat /proc/environment/ethaddr
cat /sys/class/net/eth*/address

At least the routers are in working order now, not e-waste.

Yes, this is a good step towards solving the issue

There are problems, these routers will not work correctly in AiMesh

I'm not sure if my RT-AX86U ever worked correctly as an AIMesh node. Even though I don't think it ever experienced this issue, it kept going between an AIMesh node and AP based on how it showed up in the main router. Usually in AIMesh, it doesn't show up in the clients list, but as an AP, it does. That's how I knew something was going on. Anyway, I updated it's firmware to the patched release from Nov 28, hard factory reset it with the WPS button, and put it away for a backup in case the BE92U gives me issues, I can set up the RT-AX86U fresh.

Was thinking about this - what if the RFCal values were nuked...

How to recover devices in the field?

As you know, the factory records everything, so the median and mean averages for RFCal are known, so one could generate a ballpark set of values to rewrite the RF cal values in the field...

From an FCC and EU-RED perspective - over in unlicensed space, once the radio is certified, there's a fair amount of latitude... obviously if we change something in the radio on a design view, we have to submit a permissive change request (which is usually approved)...

Not sure, but that data should be stored in the WiFi chips no? Most chips can have an OTP, I presumed this data was stored there, so it can't be wiped.

Uhm, no. However, it is extremely power limited.

I thought the UK regulations were the same as the EU. I've had UNII-3 channels as long as I've used this current router. Before that though I did force UNII-3 through an nvram hack that eventually screwed the router up.

The UK allows for higher transmit power in some of the upper 5 GHz channels and have a different regulations for channel 138 and 142.
