Poor Wireless Performance

English Network/Internet
1

Hey guys, I’ve been using Ubuntu for a little while, and I recently installed openSUSE 11.2 and upgraded to KDE 4.4.0. My wireless signal is really poor, even when I’m next to the router and sometimes I drop connection and have to reboot the computer just to reconnect. Here’s the wireless information:

09:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01

.

Other information:
Gateway NV52
AMD Athlon X2 Dual Core 2.1 GHZ
ATI Radeon 3200 HD Gfx
4 GB DDR2 RAM
OpenSUSE 11.2 64 Bit

Any way to improve performance? I had a similar issue with Ubuntu and was able to resolve it.

I do have the same problem with that specific card. My signal is far bellow that what I get with other OS’s. Under Windows or OSX I get full signal, under GNU/linux I get around 50%.

I would suppose this is driver related, I haven’t taken a look into it, someday if I get bored enough. But I do have ethernet cable available aswell here, so…

OK, so it’s likely a confirmed issue…can anyone actually help me resolve it though?

Those signal levels are pure BS. My guess is that OSX and Windows lie to make
the signals look good. The following comment comes from the Realtek vendor
driver for the RTL8187SE “// For Netgear case, they want good-looking
singal strength.” Even the typo for “signal” is in that driver.

If you want that device to work better, install the compat-wireless package for
your kernel.

I have had issues with KDE and wireless; but none with GNOME.

IPV6 enabled?

Here’s the thread I made at the Ubuntu forums. [SOLVED] Random Disconnects - Ubuntu Forums](http://ubuntuforums.org/showthread.php?t=1374910)

As you can see, same exact problem, just a different distribution. From what I can find in the SUSE forums, IPV6 does not matter. I’m just really hoping someone can put two and two together and help me fix this for SUSE as it has become the biggest pain. You have to reboot to connect (same was happening in Ubuntu before getting that solved) which makes it that much worse.
