First (you might have already done this) shut down everything. Power
cycle the modem, leaving it off for about a minute. This will clear the
modem MAC table. Power on the modem, when it has booted, power on the
router, then boot the computers. Check for valid IP address and
connectivity.

If that doesn't work then try purging the DNS cache: command
prompt/type: ipconfig /flushdns . reboot and see it that helps.

If all that doesn't work, then repeat step one, but when powering the
router, hold down the reset button on the back (yours might need a
probe) for about 10 seconds. This will reset the router but does not
reset to defaults. You can do this step first if you like, but I
always power cycle the modem without any other changes to point to the
source of the problem.

Another potential source is that the wiring has degraded and will only
support 10Mb/s and the NIC autodetect isn't picking up the degradation
and setting 100Mb/s. Setting 10Mb/s in the NIC properties will diagnose
this. Reboot.
