Wireless connection problems since upgrade from 12.3 to 13.1

English Network/Internet

Hello,

As proposed by lwfinger, I am opening a new thread, with the details already posted in
http://forums.opensuse.org/showthread.php/496142-Wireless-Connection-Problems-(Since-upgrade-from-12-x-to-13-1).

I had a similar problem – **no WLAN since upgrading two days ago from 12.3 to 13.1. **

I did have wired connection, both via “network manager” and via “traditional”.

At first “network manager” did not work at all. After upgrading the kernel to latest 3.13 (following a tip) I got wired connection, and could also sign into the WLAN (i.e. router) and get an IP address.

Despite these positive signs, there was no actual transmission on the WLAN and could not connect to web sites.

Here are the networkmanager details:

Help requested!!! Thanks!

**Update: **After a frustrating attempt to get my system working properly with SUSE 13.1 (I use it to write my math papers and to manage web pages related to teaching, and it has to be a reliable system), I gave up on it. To me release 13.1 seems quite – how to say – redmondesque. So I am now safely back to SUSE 12.3. Maybe when 13.x is stable I will try it.

Thanks to the good people maintaining and improving SUSE.

The same issue that practically every distribution has with the Realtek driver.

https://bugzilla.kernel.org/show_bug.cgi?id=60713

It’s a Kernel issue and not specific to openSUSE. I tried helping someone else with the issue but they haven’t replied to me yet - I cannot test it as I avoid Realtek like a plague wherever I can.

I read that thread and indeed it looks like a kernel issue.

Nonetheless, on the premises that I won’t change my hardware and that SUSE 13.1 can’t work with kernel < 3.10, this is also a SUSE 13.1 issue.

Hi
One question, why the non standard kernel? But since user lwfinger is
one of the driver authors, maybe he will offer some further insight? I
do note there are some module options related to power saving that may
be appropriate to tweak?

Hi
Strange indeed, you might try the 13.1 rescue cd since it’s a ‘live’
version and see how the XFCE Desktop fairs with your hardware.

I tried the 13.1 rescue cd, with XFCE. Same problem: the networkmanager recognized my wireless router (although it showed an unusually low signal (unlike max signal I get normally)), then tried in vain to connect for some time, then gave up.
