Wifi woes,

English Network/Internet
1

Hi I can’t for the life of me figure out how to get my wireless on.

Its normally switched on by a switch on the front of the laptop but that does not seem to work with linux

I am running opensuse 11.0 the pc is an acer aspire 5670 laptop.

I have read the stickys and from them I have this info from trying out the various tests. I see on the end test that it has a line that says access denied. Dont’ know if that has any bearing on the problem???

Thx in advance

Obviously your wlan card works OK, you just have to make it associate with your AP. To achieve this, go to YaST/Network Devices/Network Settings and ADD a wireless connection (just follow the prompts, remembering to fill in the right settings as required: your ESSID, WEP/WPA encryption etc.) It’s best to set it to activate at boot (via Network Manager). After a reboot (and possibly a little extra tinkering) it should work perfectly.

OK my wireless is now working after putting in the ssid etc and doing a reboot, but if I click on the signal icon down on the task bar a popup appears with the available wireless networks.

When I click on my router the connection is broken and can’t reconnect, I get asked for password info even when i enter it it still doesn’t connect.

I had to reboot to get it to connect again.

What gives??

Hi
Is your AP hidden? If so try making it visible. Also try restarting the
network rather than a reboot;


sudo /sbin/rcnetwork restart

I tried the rcnetwork restart thing and it does not solve the issue of reconnecting to my router.

Only a complete restart of the pc makes it reconnect to the wireless router

BTW the router brodcasts its ssid and its using wpa encryption.

Hi
Then if you try removing the module and re initialize;


rmmod <module name> && modprobe <module name>

Thanks, but how do i know what to type in the <module name> I’m finding this command line stuff a steep learning curve so please go easy and have patience.

Thx

Hi
Just a quick question did you install the iwl3945-ucode firmware rpm?


sudo zypper se iwl

There are a few modules involved can you post the output of;


lsmod

lsmod show a list of all the modules running.

Hi
So the firmware is installed, the above modules would need to be
removed and re probed, I would try the iwl3945 and mac80211 first…
but it’s all very strange, it should work without the issues your
having.

Are you sure your system isn’t trying to connect to another AP in the
area? What is the output from;


sudo /usr/sbin/iwlist <your_interface> scan

Thanks malcolm,

this is the message returned from the terminal.

del@linux-tdk3:~> sudo /usr/sbin/iwlist <your_interface> scan
bash: your_interface: No such file or directory
del@linux-tdk3:~>

I guess that i’m supposed to put something in place of “your_interface”

but to be honest I have run out of patience with linux, its too involved for my abilities.

I have other problems like earlier when a youtube window hung maximised i couldn’t work out how to get back to the desktop and had to power off and restart.

So I am going to go back to windows, it seems more friendly for the terminal shy.

Give me spanners and hammers any day.

Thanks for all your help though.
