Bell Giga Hub 2.0 (Firmware 3.11.3) - Ring cameras, WhatsApp calls & remote access stop working after 7–10 hours until reboot
I’m trying to determine if this is a firmware bug, a hardware issue, or something specific to my setup.
Setup:
Bell Fibre 3 Gbps up/down
Bell Giga Hub 2.0 (white)
Firmware: 3.11.3
Around XX devices connected (smart home devices, phones, TVs, etc.)
Issue:
Every 7–10 hours, certain applications stop working:
Ring cameras lose remote connectivity.
WhatsApp voice/video calls won’t connect.
Other remote access traffic also stops working.
The strange part is that general internet browsing still works, and as soon as I reboot the Giga Hub, everything immediately starts working again—for another 7–10 hours.
So far I’ve only been rebooting the modem, but the issue always returns.
I’m planning to:
Disable Bell Guard (if it’s contributing)
Factory reset the modem
Contact Bell and request a Tier 2 escalation and possibly a replacement modem
Questions:
Has anyone else with a Giga Hub 2.0 and firmware 3.11.3 experienced this?
Did Bell identify it as a firmware issue or replace your modem?
Did using your own router (ASUS, Ubiquiti, TP-Link Omada, etc.) solve the problem?
Are there any settings (IPv6, Bell Guard, SIP ALG, Wi-Fi optimization, etc.) that permanently fixed it?
