Wifi doesn't work

English Network/Internet
#1

Hello,
I installed openSUSE 11.3 under 2 machines, one of them using a Linksys USB wireless N adapter (rt73usb) and another using an Atheros AR5001 Wireless Network Adapter (ath5k). I have a Belkin f5D8236-4 router, with the SSID “linksys”. I also have an Ubuntu 10.04 machine which has working wireless internet. I know almost nothing about networking, but from what I can tell, openSUSE 11.3 seems to have trouble with DHCP, specifically setting the dynamic IP address. To try to go about fixing this, I attempted to set a static IP, but I am quite confused by all the settings.

I have tried both the graphical “Network Manager” (KDE, Gnome, and command line versions) and ifup, both with no luck.

Here is the information from the working Ubuntu machine:

Any help, including a static IP solution (and configuration help) or information how to fix this DHCP problem is appreciated! I can of course, give more information if needed.

Thanks!

Hi there,

what i can tell is that i had problems with the rt73usb too.
But i didnt tried to fix it, i just bought an new one.

I was able to produce an output via

setting the wireless account:

iwconfig wlan0 essid <your essid> key <your key>

your key should be have an prefix which tell what kind of key it is, i tried with an HEX WEP so there is no prerfix, ascii should be an s: and so on.
After that i used “dhcpcd wlan0” to get an IP Adress from the Server, but the connection was terrible slow.
Round about 1.4 kb/s where the network on any other machine does about 450 kb/s.

So I think there is a kernel issue to this chipset.

Sorry, but i cant provide any other information, but maybe anyone else? :slight_smile:
