I have a setup with non-FIOS main router and MI424WR-I set into a local bridge mode. I did not have problems for quite a while. A few weeks ago though TV guide on my 7100 STB stopped working. The tv box shows IP address in its system info and I can ping it from my local PC. Putting the Actiontec back as a main router works which verifies both Actiontec and Motorola hardware are OK. Did anyone experience the same problem? Any remedy?
