Replace xxx with 1 to access the routers setup pages in your browser.

What I've seen is that the PC and my laptop (different OS versions) even after power down and re-boot don't always re-request the DHCP, just go on trying to use the old one.

I fix it by using CLI instructions

ipconfig /release_all

and then

ipconfig /renew_all

Worth a try. (It may be having the same effect as repairing the connection but I like the CLI instructions better.)


Those same ipconfig instructions avoid rebooting the PC when changing from direct connection to the modem and connection to a router.
Cisco/Linksys use 192.168.100.0/24 as the default subnet with a default gateway of 192.168.1.1. The "repair connection" tool does what the ipconfig /release renew does plus more
