TP-Link WR641G Losing connection
 

Help please,

I recently bought the above router for use with my 10mb Virgin Broadband,

Which works ok most of the time unless I try to do multipal tasks, then speed slows down and sometimes lose's connection altogether,

Im running it Wireless, Using a Laptop with Vista OS,

Have I forgot to tick a box or put in a number when setting up my connection,

Any help would be great.

Many Thanks Pete
