Wireless Network

Okay, installed Arch yesterday for the second time. Used a wired connection to get all updates and programs needed. When I first went to setup my wireless I got this message:

[root@myhost isa]# ifconfig wlan0 up
SIOCSIFFLAGS: No such file or directory

So I started looking around online, and looked up my chipset:

[root@myhost isa]# lspci | grep -i net
00:14.0 Bridge: nVidia Corporation MCP51 Ethernet Controller (rev a3)
02:09.0 Network controller: RaLink RT2800 802.11n PCI

Found out that it is not supported automatically. Went to the supplier's website and downloaded the .zip file. I read that I needed to put the RT2800.bin file in /lib/firmware

...easy enough, now I'm retrying the setup and I am so close, but when I do the wlist scan it seems it's not linking maintaining the information. This is what I get:

[root@myhost Desktop]# iwconfig
lo        no wireless extensions.

Re: Wireless Network

FuKaS - read his post again. He has already done what you suggested.

jargowsky - it's possible you are running into a driver conflict between the kernel's official rt2x00 driver rt2800pci and the staging driver rt2860sta. There is at least one other thread on this topic - have a read, see if the solution there works for you.

Re: Wireless Network

Try wpa_supplicant for the connection.
The only way to make my RT2760 work was with the following procedure:
- I compiled and install rt2870sta module (I think you have already done that)
- I created a file called wifi_up.conf (wpa_supplicant.conf type). I recall finding toons of examples in Arch Wiki somewhere for any wireless configuration you can think on (WPA, WEP or with no security at all).
- I loaded it with

[root@myhost]# wpa_supplicant -B -Dwext -iwlan0 -cwifi_up.conf

- After that, "dhcpcd wlan0" should work.

Re: Wireless Network

tomk - Your link to the other forum helped out quite a bit. I believe that was exactly what I needed. My only question I have before I start trying to finish up this issue tonight is: will I need to restart or anything like that after blacklisting a module?

Re: Wireless Network

You don't need to restart to get it working. Blacklisting it now has no immediate affect - it just makes sure the module won't be loaded next time you reboot.

Re: Wireless Network

tomk - Awesome, that answers what I hope to be my last question. I'll let you know as soon as I get home from work tonight.
