Looks like interference from other networks, microwave,
phones, etc.
If you operate the router for the 520 only, set the router
to operate as b device only.
Then, experiment changing the channel on the router and
wifi card (keep same channel on both). Try with channel 1
and 11 -- these chanegs slightly the operating frequency,
and sometimes helps.
It may also help changing the channel on any portable phone
operating on 2.4 MHz to the opposite side of the spectrum.
Set the router vertical and away from walls. Wifi is like
old time under-powered radios (or TV's). Slightly changing
their position may help.
The final thing you may want to try is using an extension
antenna -- check
www.freeantennas.com for instance for DIY
antennas.
