Re: Fedora 24 and ASUS PCE AC-88

Should we expect the card to work through official channels in 4.8? One thing I did notice is there's a commit in 4.8 about the Broadcom contributor changing.

Thanks for your time.

I've tried setting country, both DE and SE. When looking at iw list all the frequencies are set to "disabled" regardless of setting:
Frequencies:
* 5170 MHz [34] (disabled)
* 5180 MHz [36] (20.0 dBm)
* 5190 MHz [38] (disabled)
* 5200 MHz [40] (20.0 dBm)
* 5210 MHz [42] (disabled)
* 5220 MHz [44] (20.0 dBm)
* 5230 MHz [46] (disabled)
* 5240 MHz [48] (20.0 dBm)
* 5260 MHz [52] (disabled)
* 5280 MHz [56] (disabled)
* 5300 MHz [60] (disabled)
* 5320 MHz [64] (disabled)
* 5500 MHz [100] (disabled)

* 5540 MHz [108] (disabled)
* 5560 MHz [112] (disabled)
* 5580 MHz [116] (disabled))
etc etc
There's also some errors in dmesg regarding brcmfmac. Link below.

Re: Fedora 24 and ASUS PCE AC-88

Hi all,
I tried the same recipe as well explained by Hellacopter, but the 7z command does not work for me.
I have to admit I try this on ubuntu 16.10 (also on 16.04 with same effect). Probably you will tell this is not the right forum, and I accept.
I just want to tell that
"7z X RT-AC88U_3.0.0.4_380_3341-g25420f5.trx"
gives the error
"7-Zip [64] 9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18
p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,1 CPU)

Processing archive: RT-AC88U_3.0.0.4_380_3341-g25420f5.trx

Error: Can not open file as archive"

I tried with other more recent trx files available on the ASUS site, with same result.
I would not expect such a difference between Fedora and ubuntu. If anyone has similar experience with a (easy?) solution I will be pleased of course.
All the best.

Re: Fedora 24 and ASUS PCE AC-88

Meanwhile I was able to extract the trx file by using the firmware-mod-kit.
You can use :
git clone https://github.com/rampageX/firmware-mod-kit.git

Another question : are there different brcmfmac_xxx.bin files for 32 and 64 bit OS systems?
If yes, how to extract/build the correct one?

Best regards
Lucca

Re: Fedora 24 and ASUS PCE AC-88

Interesting posts, I couldn't get it to work unfortunately.

I managed to extract the firmware from the router download and the SHA1 checks out okay so I think that part went fine.

The extraction doesn't work on Ubuntu though using the p7zip command. It does on OSX as Hellacopter used I think. I couldn't get it extracted with the 'firmware-mod-kit' either, or sasquatch which I also found.

My problem is that in lshw output the network card is listed as UNCLAIMED and I cant work out how to fix it.

Strangely if I installed wl driver this changed, but that driver doesn't support this chipset.

Were there any other things you guys did to get this card working?

I just have brcmfmac module enabled and everything else blacklisted. I put the firmware file in the correct place also.

Also does this incorrect device recognition make difference?

Re: Fedora 24 and ASUS PCE AC-88

I sussed the above problem, needed to use a later kernel. I was on 4.4.0-53 and moving to 4.8 sees my card being recognised. Thanks for the info.

Re: Fedora 24 and ASUS PCE AC-88

chrismacp, do you mean that all you had to do to get this card to work is install kernel 4.8? The card doesn't seem to work for me, even with 4.8 or 4.9.

What steps did you follow to get it to work? I wasn't quite able to follow everything in this thread, so I was hoping that the new kernel would fix my problem. Unfortunately, the card still shows up as "network UNCLAIMED" with lswh.

Any hints would be greatly appreciated!

Re: Fedora 24 and ASUS PCE AC-88

@quickk, no I followed the instructions earlier in the thread to create the firmware file.

Whilst still on kernel 4.4.0-53 (on Ubuntu server) my card was UNCLAIMED in lshw.

I upgraded the kernel to 4.8 and then my card was recognised.

I do have other problems though and it is not fully working yet. I get P2P issues as Hellacopter mentioned although I can't get rid of them with his fix. I'll report back if I can get it fully working but maybe this is better off in a Ubuntu forum as it may be different to Fedora.

Re: Fedora 24 and ASUS PCE AC-88

@chrismacp, thank you for the update. I managed to extract the firmware file (dhd.ko) using p7zip on a windows machine. The SHA1 sum is the same, so I think that I got the right firmware.

I then did
Code:
dd if=dhd.ko skip=1269516 ibs=1 count=935317 of=brcmfmac4366c-pcie.bin
as indicated by Hellacopter. I copied this new brcmfmac file to the /lib/firmware/brcm/ folder. There's already a bunch of other firmware files there, but I figure that's ok (right?).

Now I'm not really sure what to do. I rebooted and using the 4.9 kernel, lshw still says that my network card is UNCLAIMED. Is there anything else that I have to do? I really appreciate your help!

Re: Fedora 24 and ASUS PCE AC-88

Hi quickk,

Sorry for the delay, had a lot on. I still didn't get it fully working actually but the card is connected to my router on 5Ghz. Just cant get any communication with it

I was having some errors in the errors log and after scouring the internet for all information I decided to do a fresh install (Ubuntu server). Then I copied over the driver like you mention to /lib/firmware/brcm. The other drivers in there are fine to stay.

After I do that the card is picked up and I dont see the UNCLAIMED any more. You should maybe check that you have only go the brcmfmac driver loaded. You may have to blacklist other broadcom drivers like 'wl' or 'bcm43xxx'. I didn't have to do any of that with my fresh install.

$ sudo lspci -vv will show which driver the device is using, it should only have brcmfmac

@anyone else

I managed to get this card to connect to my router and it gets an IP, but pinging that IP just fails and trying to SSH etc doesn't work. Also logging in to the machine itself and trying outgoing HTTP requests fails.

Any ideas of what else might be up or that I can check?

Re: Fedora 24 and ASUS PCE AC-88

Are there any news in a more official solution to this?

I must say, even though it's working with brcmfmac4366c-pcie.bin from the RT-AC88U, it's not very stable (for me at least). If I'm using 2.4GHz I'll get HT MCS 15 and it's working quite well. But on 5GHz it's barely working at all, I'm usually stuck at legacy rates and keep loosing the link.

I'm still using the firmware from RT-AC88U_3.0.0.4_380_3341-g25420f5. I tried the newer ones (for example RT-AC88U_3.0.0.4_380_7266-g6439257) but it's that's not loading at all.

It would be cool if a working driver could be integrated with the broadcom-wl package anytime soon, but I haven't seen anything about that happening.
