hey, im using the athlon version(bought in Oct 09) and i have some problem with my wireless network...

I noticed that my K40AB most of the time got problem with the wireless connectivity... the signal strength is normally 1-2 bar... but my laptop is one floor above my router... my friends laptop can receive full bar for the wireless connection.... whereas mine sometimes only i see 3 bar

Is the wireless for K40AB that weak? cos i tried once putting it on the same floor as the router and still not stable..
