Verify you’re using the correct router default IP address (usually 192.168.1.1, but may be different). Make sure your computer is using DHCP to self-configure itself. And preferably use a wired connection for setup purposes. Now hold the reset button on the back of the router for 30 seconds (while powered on, of course) and release. Reboot your computer. Try again.
Ya, the router IP is 192.168.2.1, have to reset my systems IP. This is the first router for me not in the 192.168.1.x range. Duh me.
BTW, this is a good router right?
