I have a Cisco RVS4000 router. Wired. (Computers on my net are running 2000 and XP). Up until two days ago internet speeds were okay — within ISP tolerances. But then suddenly the upload speed slowed down and locked in at .470mbps. Every speed test gives that +/- .01. Nope, it’s not the ISP, It’s not the computers. I had a spare identical router, put it into the system and speeds are back to “normal”. Put the original back in and speeds go back to .470. Rebooting doesn’t seem to help. All internal settings on the routers appear to be identical. So I’m stumped. Anyone got any brilliant ideas?
