My Droid Maxx phone has stopped finding the 5 Ghz WiFi signal from my main FIOS router and the new extender I just purchased. The main router is a FIOS G1100 and the extender is the Actiontec WCB6200Q. I can access the 2.4 Ghz signal from eithier router but not the 5 Ghz signal. Other devices, like iPhones, iPads, and laptops can find the 5 Ghz signal. So it must be the phone but has anyone experienced anything like this? The phone has picked it up before but now cannot. I am wondering if there is any tweak that needs to be made on the router or if someone has had a similar experience. It is very frustrating. Motorola, which makes the phone, says it should be able to get the 5 Ghz signal...but it does not. Any suggestions (please don't just say buy a new phone) would be welcome. Thank you.
