My modem keeps rebooting

[everettt]

Since this morning, the modem has been stuck in a reboot loop: welcome/bienvenue -> loading/chargement -> connecting to bell, then after a minute, back to welcome/bienvenue… forever. Chat support said it was a defective modem and gave me a ticket to replace it at a local branch, but the replacement does the same thing. Now tech support (voice this time) insists that the replacement is also defective, which seems unlikely. I noticed also a complete absence of BELL123-like ssids in the neighborhood, which seems consistent with a wider outage - but nothing is indicated on the outage site, and support refuses to send a technician. 
Is there any way to connect to a human who is not just following a script?

At the very least, this apparently common failure mode should go into their knowledge base, so they stop recommending pointless modem swaps. I’d bet that almost all modems exchanged for endless reboot are actually fine.

Does not sound like a broad power supply issue.

Modems could reboot/loop for a lot of reasons, and power supplies fail. I don't think there is a widespread problem with the power supply. At least not based on these forums.

The power supplies aren’t failing per se, they’re just under-spec’d for the gigahub. During normal startup, it pulls current close to the psu’s rated maximum, and depending on how long the negotiation lasts, which other components (eg wifi) are also peaking simultaneously, etc. the current limiter sometimes triggers. You can see this on an ammeter.
