I wanted to share a solution to the problem of Gigahub reboot loops.
Last Sunday, my 3GB fiber Internet service disconnected our of the blue.
I noticed my Gigahub would reboot, and, before connecting, it would start booting again with the Welcome message. The connection would show 3 of nine dots, then reboot.
I called Bell and after some troubleshooting, the phone tech determined my Gigahub was the problem. She instructed me to return it to a Bell store for an exchange.
When I disconnected it, I noticed the green light on the power brick would not go out, even when unplugged.
It was late and I could not get an appointment that night (you have to book an appointment for a return), so I thought I would try another power brick I had on hand.
Lo and behold, the Gigahub rebooted just fine with the replacement AC adapter and has been running since.
The Gigahub power adapter is rated 12V 5amp. The power brick I used is rated 12v 10amp (using a higher rated adapter is safe and works fine.)
So, if your Gigahub starts acting up, check your power supply. Amazon sells 12v adapter for around $20. I suggest using a 12v adapter rated higher than the original 12v/5 amp adapter (6-8 amp should do the trick, 10 amp is likely overkill.)
I suspect that at 5amp, the original Gigahub adapter is underpowered and the reason why mine failed. Only Bell techs could tell you how many Gigahub are returned simply because of burned out, underpowered AC adapters.
I called Bell to tell them about the bad AC adapter. She said great and did not offer to refund me for my adapter, nor to send me a replacement. She did, however, helpfully tell me if I ever have problems again, to run their self diagnostic tool (which would be totally useless for a reboot loop problem.)
