Problems with the EDUP MS8551 USB WiFi Adapter for PC - High Gain 6dBi Antenna #326

Open DealBreacker opened 8 months ago

DealBreacker commented 8 months ago

Setup: Raspberry Pi 4B 8gb model OS: OpenWrt 22.03.5 Kernel version 5.10.176

The drivers for this adapter seems to not be working.. (Working with OpenWrt O.S). Go the adapter in today, plugged it in, installed the firmware and mt7601u.bin, properly in /lib/firmware/MediaTek, and the firmware refuses to load.

Continuously receiving a "Direct firmware load for mt7601u.bin failed with error -2" followed with "probe of 1-1.1:1.0 failed with error -12". Did some extensive research, seems to just be a faulty driver + hardware issue known for this adapter. If anyone has run into this issue and found out how to fix is please let me know as it is driving me crazy and I might just have to return the adapter :(.

Don't let it driver you crazy. (pun inteded)

I have not tested my Edup with mt7901u chipset with OpenWRT. Why? Because the mt7601u driver does not support AP mode. For reference:

https://github.com/morrownr/USB-WiFi

See Main Menu item 5. USB WiFi chipset information for Linux. See Main Menu item 2. Plug and Play List. Go to mt7601u chipset section.

With that said, I think your little Edup adapter is almost the perfect little plug and play adapter for a wireless toolkit as it does not cost much and sometimes things happen and you need something that just works in managed mode to help get things going again.

I have used several adapters with OpenWRT and can suggest some that work well. Keep in mind, you should not need to manually install the firmware for these adapters as it should install when you install the driver. The best chipsets are mt7921au, mt7612u and mt7610u.

I'll throw a couple of ideas out:

Let me know if you need further advise.

Ahhhh, I made a mistake when I was buying the edup adapter then! :P I'm going to keep it anyway, since it was only $8. Thank you for the clarification!

P.S: How long normally does AliExpress take to ship things? Do they overestimate or underestimate their shipping time? If you don't know then just ignore me!

Do they overestimate or underestimate their shipping time?

Based on the comments I have seen over the last year, I'd say most of the time the adapter arrives on time or early.

Error -2 appears to be „No such file or directory”. On my (Arch Linux) system, the firmware is in /lib/firmware/mediatek. You wrote /lib/firmware/MediaTek, which is not the same. The case matters.

@dubhater

Can you be specific about where you see '/lib/firmware/MediaTek'?

I am well aware that case matters but sometimes mistakes are made.

It's in @DealBreacker 's original post:

@dubhater

I see. I missed that. Good eyes.

@DealBreacker

Do you understand what @dubhater is saying?

DealBreacker commented 8 months ago

Yeah I get what he is saying. I will check when I get home if I wrote that down wrong or not. Thanks for the info! When I figure it out I'm going to send it here to let y'all know.
