I recently had Fios 400/400 installed and added an Actiontec WCB3000N extender, connected to the house’s coax to alleviate a dead spot in my home. My phone connects fine to either of the extender’s bands, (‘...2.4g ext’ or ‘...5g ext’) without any issue, but once I connect to the extender, the phone will not connect to the Verizon router, no matter how close I am to it. I have turned off the phone, restarted it, turned off/on the phone’s Wi-Fi, and nothing will allow it to connect to the main router after it connects to the extender. I also tried pairing the extender to the Fios router with the WPS button, but that didn’t have any effect. Only if I unplug the extender completely will the phone connect to the Verizon router. Anyone have this issue? Suggestions to remedy it?
