laptop PCMCIA problems

[sandman112]

a mate of mine has asked me to look at his laptop, and ive come accross
something very bizzare

it comes with a PCMCIA wireless network adapter, only thing thats on it is
model nuimber wa1220, funny thing is that it will only connect to my router
when the laptop is running on batteries, and as soon as i plug in the AC
power it disconects again, the card still works as it can see my network, it
just cant connect to it

anyone got any ideas on this one, ive been googling all night but found
nothing even remotly close to this

Laptops have different power usage settings when either connected to
external
power or on battery power. You might check those settings, maybe you
have it
set to turn off on external power.
