Enabling Ralink RT3062 Wireless on ZyXel P-2812HNU-F1

[piotrv]

I am trying to get the RT3062 working on a good old P-2812 HNU-F1 but I can't manage to generate a /etc/config/wireless file, since neither wifi detect nor wifi config is outputting anything.

I am a rookie in regards to OpenWRT on this device.
Someone recalling how to get it done properly ?

Did you look through your full dmesg output, to see if anything else is amiss? There might be something with the driver itself and filtering on your part number will leave that out.

That being said, it looks like a chip that hasn't the best track record on Linux to begin with. Anything that turns up with that PCI ID are topics that end with 'wasn't able to get it to work'... Hope you do though.

[piotrv]

You are right. I was too sloppy in checking the lot from dmesg output

[   10.962422] ieee80211 phy0: rt2x00lib_request_eeprom_file: Info - Loading EEPROM data from 'RT3062.eeprom'.
[   10.988874] ieee80211 phy0: rt2x00lib_request_eeprom_file: Error - EEPROM file size is invalid, it should be 512 bytes*

So, this might be the culprit . . .

[Borromini]

I found this old Ralink EEPROM bug report.

And this commit that changed the EEPROM file size.

[piotrv]

YES ! A corrupted EEPROM file was the real culprit.
I got the 512 byte file from ScAPI and everything is sweet now :

@Borromini Thanks for helping me out !

Does wifi work stably? It does not exceed 50 mbps. it is also not stable. That's why I use unifi ap connected.

[piotrv]

@ altuntepe

I never got beyond 802.11g @ 2.4GHz, so 54Mbps with the RT3062 in this P-2812 with OEM F/W anyway. In regards to stability, I experience no disconnects. My cisco ap is for daily use (2.4GHz/5GHz)

UPDATE
With the working rt3062, I just tested the wireless on an Android client and get:

6.0 Mbit/s, 20 MHz
78.0 Mbit/s, 20 MHz, MCS 12

Within 10 m range from the P-2812 I get even 144.0 Mbit/s.

I have chosen a free channel to reduce interference with other radio signals.
So , if I can believe the figures, it's better than I ever got before with this P-2812
