I installed Ubuntu 11.10 on my home desktop and am having problems with the wireless network. It actually makes the connection, but it is so slow and unresponsive it is unusable.
My wireless network adapter is a D-Link DWL-G520 rev. B with an Atheros chipset, and this is the relevant output from running lspci.
$ sudo lspci -vvv 04:02.0 Ethernet controller: Atheros Communications Inc.

What other information could help finding the root issue? What logs should I check?
The network is working fine now. Not sure what did the trick, if some fiddling with the router or upgrading network-manager
