Humax BGW320-500 modem intermittent service

So you have Att Internet with Fiber, yes?   

What exactly is failing, WiFi connection, wired Ethernet, or both.  Are the LEDs solid green for power and service?

I do have fiber that was installed on our street last March and it’s the WiFi connection that just cycles through multiple times each night: flashing red, flashing white, (sometimes back to flashing red), solid white (which can hold anywhere from 5 seconds to the next morning), then back to flashing red or white. At this moment, it’s been solid white and good since about 11 last night but I expect it’ll start cycling any time now. My wife and I are betting each other when it’ll start — sometimes you just gotta laugh (even if it’s ruefully).

Update:  after doing even more research, I ran across info that says the modem should not be plugged into a surge protector, which is exactly what the install tech did 6 months ago.  So I unplugged from the surge protector and plugged the modem into a wall outlet.  I've gotta say I wasn't expecting this to work (seems way too simple) but apparently it has done the trick!  Didn't move the modem, reboot or reset but I guess the magic was effective:  no disconnects for over 24 hours now!  I'll give another update in about a week if this solution sticks, otherwise I'll be back with a less positive update.  Thanks to all who tried to help.  

Dear ATTHelp: you were premature thinking my problem was resolved. After about 59 hours of trouble-free performance, our modem did the following over the past 20 hours: 

Sat 3:30 pm: cycled through flashing red, fast flashing white and slow white about 6 times over the course of 9 minutes until restoring full signal. 
Sat 8:35 pm: fast white for about 4 minutes with no signal, so I disconnected power and regained solid white signal after about 2 mins

Sat 8:58 pm: cycles through red, fast white then solid white 3 times over the course of a minute. 4 times of fast white flashing for about 2 mins before solid signal. 
Sun 12:45 pm: flashing red for about 6 minutes the goes straight to solid white for about 3 mins. Sporadic flashing white ever since. Made it difficult to even send this message with signal going in and out. 

I’ve had it with this inconsistent performance so am calling Charter to rejoin their service. I’ve had many more connectivity problems in the past 6 months with ATT than I had with Charter over 5 years. I’ll be spending $150 more a year but it’ll be worth it they can give me the level of service I got from them in the past. I guess you really do get what you pay for.
