[Possible Spam]::Re: Colony 4: wifi problems on HP laptop

with my AMD sempron laptop, if i use the stock 386 kernel my network 
card/ndiswrapper works fine. but if i use the K7 kernel i have problems 
with wifi being sporadic and sometimes lockups. i think there's an 
ndiswrapper-sources package in world; why don't you try building 
ndiswrapper specifically for your kernel to see if that helps.

also, i'm not sure the kernel options are compiled into the kernel, but 
you might want to verify that the 4k stack option is NOT used (if it's 
relevant for amd64, i don't know). i think i remember reading somewhere 
that this gives some ndiswrapper-wrapped drivers problems. as a last 
resort, you can try to 'roll your own' kernel to see if that helps.

hth,
alvin
