rt2870 issues [SOLVED]

mkloch · 2011-08-05 09:09:13

Hi. I know this appeared on forums many many times in the past, but after researching various topics and wiki pages, I still didn't solve my problem. I have a wifi card that I believe is using rt2870 driver . I had it working under my previous arch install with gnome 3. yesterday I reinstalled my system and have KDE now. I followed the instructions here:

https://wiki.archlinux.org/index.php/Wi … and_rt2870

but it didn't work for me, although it did on my previous install. then I updated my kernel to linux3.0 from [testing], as suggested here:

https://wiki.archlinux.org/index.php/Ta … and_rt2870

but it didn't fix it either. So wireless card is recognized in the system, i can use networkmanagement applet in KDE system tray to choose a wireless network, it is trying to connect, then takes ages at the 'waiting for authorization' stage to fail every time. i checked the password several times. any idea where I went wrong? is it something to do with KDE setup?

Not sure, but what's the output of

ls -1 /etc/modprobe.d/

?

I am one of the users using rt2870sta driver currently, guide of blacklisting other modules should work, also some tweaks to complete was removing/replacing "network" with "networkmanager" service rather and taking down the part of "rc.conf" own address or dhcp information, as for me the networkmanager finds network on and is able to bring it functional state without the additional package of dhclient installed.

What goes for upgrading into linux3.0 from (Testing) reposity it did not have module around, so currently the .39 is highest working without compiling own kernel.

What about https://wiki.archlinux.org/index.php/Rt2870

NOTE: In kernel 3.0 it seems it is now using the builtin rt2800 driver

thanks for your replies

@Karol, the output of

ls -1 /etc/modprobe.d/

is

modprobe.conf
usb-load-ehci-first.conf

@Jasa, I've got network disabled and network manager handling all the networking stuff

Looks fine.

~~Linux 3 is in the core repos already, so if rt2800 driver can handle your card, go ahead and update :-)~~
Sorry, I forgot you're already using linux 3.

Read here: http://aur.archlinux.org/packages.php?ID=14558 - you will be happy with official kernel drivers now (rt2800usb and so on).

Anybody else finding the official kernel driver ridiculously slow? The package in the AUR was much faster for me anyway...

Yes, and I went back to my old 2.6.39-ck and am using the rt2870sta driver again until it gets sorted out.

karol · 2011-08-08 03:33:19

mkloch, can you please edit the title so that it mentions the new kernel? I think it can help a lot when people are deciding whether to update already or not, like e.g. castlevaniahellraiser.

80-90 Mbit/sec - is it slow?

No I was getting over 200Mb/s most times. I just had really long dns lookups and pretty bad throughput.

As soon as I went back onto the AUR version my problems were gone.

Do you mean real stable transfer (say, from samba server or ftp server it will be about 24 MByte/sec)?

Haven't tested it over samba or anything, only internet access. I was getting wireless N, but very slow throughput. Sites taking forever to lookup and forever to load. I'm using netcfg, if that makes any difference.

So what do you mean saying about 200 Mbit/sec? And what sense does this number have without real testing?

Have you tried to use name servers other than default (from provider)? Say OpenDNS or Google's ones?

That's the connection speed to the router. I have a 50Mb internet connection though. Wireless N goes up to 270Mb I believe. Yes, tried other DNS servers. The fact that the problem disappeared when reverting to the AUR driver tells me enough.

Sorry for hijacking.

I think it is just theoretical limit. I always test reality as far as use this reality Of course it is handy to have another wire (UTP) connected to router station to be able to test a speed between this station and wifi client.

mkloch · 2011-08-08 16:44:04

since linux kernel 3.0 is in [core] now, I have made a fresh install again and everything works out of the box.

castlevaniahellraiser · 2011-08-16 22:29:38

No need to reinstall... try using http://dl.dropbox.com/u/169548/2010_070 … .1.tar.bz2 just untar with

tar xvjf

it then

make install

and it should work when you reboot.
