Loss of speed with Dell 1703 wireless nic, Cisco DPC3939B router
We've had a good, stable system for a while now, with high speeds on all of our computers.
A couple of weeks ago (2-3?) the bottom dropped out for one of the computers. Throughput is down to 1 or less megabits/s. No problems can be detected. I attempted to roll back to a 3-4 week old restore point, with no effect. I reinstalled the drivers, no change. We downloaded updated drivers and motherboard bios, with no effect. Ran Dell's diagnosis software and repair software, no effect.
I then plugged in a Netgear USB NIC, and it works just fine at 50 megabits.
did the gateway receive a bios update with the last 30 days?
has anyone else with a Dell system - and specifically a Dell 1703 network adapter - reported a similar problem?
has a solution been found?
