Wondering if someone can help me out.

Draytek router with g wireless and a Cisqo lan card with a lappy.

Around the house the cisqo reports different % of stength of signal. While in the lounge it's 60% and works faultless but move to the conservatory and the signal reaches around 50% but webpages wont load although it still reports a signal.

It has happend while using a apple airbase too so dont see how it's the draytek.

Bit of a wireless n00b so wondering if anyone has any advice?
