I've had the WRT54GX2 for about 4 months now. Its been causing problems since day one. After some of my problems Linksys told me to upgrade the firmware. I attempted to but it never worked. It turned out that i had to change the extension on the firmware file from .bix to .bin. I have no idea why. But that finally worked and the router was working great for like a week or so. Now another problem has appeared. On my laptop I always get excellent signal but the throughput keeps on dropping. I have no reason why. I have the latest firmware and the latest drivers for my wireless card. I've tried everything. Anybody have any ideas?
