My brother’s Netgear Router slows down when he got too close. He ended up returning the router for a Linksys WRT54G and everything is working fine. We think the problem was interference – other wireless devices on the same channel and he couldn’t get his Netgear router to change channels.
The netgear router was stuck on channel 6 and he found another AP on channell 6 and another on channel 11. So he setup the Linksys on 2 and everything is fine.
