I am having trouble with my wifi on a laptop. The main trouble is that my connection just drops every 2-4 minutes or so. Moreover, when the connection is established, the speeds are about 1-20kb/s (I have fibre and my speed should be much higher). My notebook is located right next to my router and whenever the connection is established i have about 3-4 bars. I have 2 desktops using ethernet (1 with openSUSE 12.2 KDE the other is Arch) and another laptop that runs ubuntu with unity (over wifi), none of them have any trouble with connection and speeds.
I am trying to run openSUSE 12.2 xfce on an HP Pavilion. I am not sure which commands i need to execute in order for you guys to have a better understanding of what might be the problem. But here are some that I came up with:
Linux Xenox.site 3.4.6-2.10-desktop #1 SMP PREEMPT Thu Jul 26 09:36:26 UTC 2012 (641c197) x86_64 x86_64 x86_64 GNU/Linux
/sbin/lspci -v

03:00.0 Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)

Flags: bus master, fast devsel, latency 0, IRQ 19

Capabilities:
Kernel driver in use: ath5k
iwconfig
wlan0 IEEE 802.11bg ESSID:“HOME”
Mode:Managed Frequency:2.412 GHz Access Point: 10:BF:48:3D:F6:1F
Bit Rate=1 Mb/s Tx-Power=20 dBm

Power Management:off
Link Quality=70/70 Signal level=-39 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:5 Invalid misc:7 Missed beacon:0
Also, sometimes (rarely) i get normal speed and everything seems to work but after a period of time i lose connection =(. Could it be the driver that is a little gimmicky? Is there any other information that i can give you that might help to identify the problem?

It could be lots of things. Your kernel is now 5 cycles old - almost a year -
and the Atheros developers have done a lot of work on ath5k. If you install the
version of compat-wireless for your device, you will get a much later version.
You could also have a lot of interference on your 2.4 GHz channel. Have you
tried other channels than 1? Use ‘sudo /usr/sbin/iwlist scan’ to do a survey of
your neighborhood to see if either channels 6 or 11 are less congested. Remember
that anything within 2 channels of the selected oine will interfere.
