Hi, my main desktop system (a dual core Athlon 4200) 1Gb RAM on an ASUS A8N-E has started suffering network slowdowns. All is well for a while and my laptop connects to it wirelessly for an hour or so via my Netgear DG834PN router, the connection through the router to the WWW is faultless but my connection via the wireless link to the desktop computer for file sharing etc starts to slow down to a crawl. I have the latest chipset drivers from Nvidia on the mobo. Any ideas??
