add edimax dongle device IDs #5

Closed joske closed 6 years ago

joske commented 6 years ago

Hi,

I was using the driver downloaded from edimax website for my USB dongle (8822bu), but it didn't compile anymore for linux 4.15. See the 5.2.4 branch on https://github.com/joske/rtl8822bu I tried to fix the compile issues, and it compiled but the driver caused a kernel panic on load.

The device is an edimax AC1200.

I then found your repo and added the device IDs from the edimax sources. This works for me.

For some reason the 5GHz band isn't working, but for the rest your driver works fine.

Relevant info: Bus 002 Device 004: ID 7392:b822 Edimax Technology Co., Ltd

Cheers, Jos

Thanks for adding the IDs. What's the Edimax model number of the dongle you're using? EW-7811UTC or EW-7822ULC maybe? When you say 5GHz isn't working, what's breaking about it? Any output you can share?

Also, in case you were curious, the Travis build failure was due to Ubuntu updating the header version that Travis is using -- nothing to do with your changes. I made a quick change (dc73ae225b8dd8b34d182cfee4b993c661e5b596) to make that more flexible.

Hi,

it's the EDIMAX EW-7822ULC. It doesn't see my 5 GHz network. NetworkManager only shows my 2.4 GHz network. Although, when I scan manually, it does seem to show some on 5 GHz, but not my network. All my other devices can connect to that just fine. I'm almost sure on the previous kernel (4.12, ubuntu 17.10), it did work with the edimax sources. Now I upgraded to ubuntu 18.04 (kernel 4.15) and with your driver no luck. Any pointers? I see that your driver prints lots of debug info ;-).

Yes I saw that the build failure was something technical, and nothing to do with the code.

My 5 GHz network is on channel 52, and is called dd-wrt5.

See attached snip from dmesg.

I just finished backporting the updates to a newer v5.2.4.4 upstream release if you'd care to try it out.

Hi,

Tried it and it works for me. Still don't see my 5 GHz network though. A manual scan only shows a few networks, there are many more around. Maybe a limit or so? Or it only shows the strongest few? Yesterday I tried a scan on the top floor where the router is, but also there the other network didn't show up...
