I have a belkin wireless router which my HP laptop has no problem connecting to and allowing me to browse the internet. My Acer Aspire, however, will connect and allow me access to the internet but then after about 15 or so minutes will still say I am connected but I cannot open any pages. Repairing the connection does not work. I have to reset the router and restart the computer to re-estblish a connection that works. Any advice?
