I recently had our local ISP replace a bad ADSL modem and for some reason, I could no longer access my router's IP. Default router IP is 192.168.11.1. Had no problems setting it up before the modem was replaced. The default gateway every time I use IPCONFIG opens up my ADSL modem gui instead. I can still access the router's gui though I have to disconnect my modem. Is there a setting I should be changing to get this working again? I've tried resetting both modem and router to defaults but still nothing. I have no issues with WIFI or internet. My router is a Buffalo Air Station N300.
