Hi,
Since upgrading to 10.10 I have a problem with the latency through the wireless being very unstable, Ping times goes between 1ms to 200 or 300 ms even when signal strength is very good.
This is pinging the wireless router
Code:
$ ping 10.10.10.1
PING 10.10.10.1 (10.10.10.1) 56(84) bytes of data.
64 bytes from 10.10.10.1: icmp_req=1 ttl=64 time=3.24 ms

64 bytes from 10.10.10.1: icmp_req=8 ttl=64 time=2.47 ms
- Prior on 10.04 I did not have this issue.
- Dual boot into Windows7 doing the same test & latency is normal so must be Ubuntu deriver issue.
- Also I've tried with other different wireless APs and while other users does not have issues with the same AP.
I've tried reinstalling the Broadcom STA driver from repository and also by building manually.
Anyone come across this?
Is it possible for me to go back to an old driver on 10.04 for example? Any direction would be much appreciated as I haven't found any in my search. Bare in mind I'm no linux expert.
My specs are:
HP ProBook 6540b
Code:
$ uname -a
Linux orc-b 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:45:36 UTC 2010 x86_64 GNU/Linux
$ lspci -nn | grep Network

$lsmod | grep "b43\|ssb\|wl"
wl 1965295 0

I've tried build the Broadcom STA drivers manually using the x64 driver

I'd like to get this fixed as even a simple telnet session via the wireless is painful.
