Bell GigaHub 2.0 Blocking Specific Applications

[LambChops713]

About a month ago after a bunch of issues with the 3000 model, speaking to 20+ call agents, and a technician appointment, Bell upgraded me to a GigaHub 2.0. Since then, specific applications like Discord Voice Chat (text chat works fine), League of Legends, Destiny 2, and even a simple Ookla ping test (speedtest.net) will not work at all. These things will either hang forever or not connect. After physically unplugging and then replugging the modem after a few minutes, the issues are resolved for anywhere from 4 hours to 2 days before returning.

Here's what I've tried:

1. IPv6 is toggled off, UPnP is toggled on.

2. Firmware is updated to the most recent version.

3. Ensured that it is a modem problem, NOT a device problem (all devices in my home, wired or wireless, experience the exact same issues).

4. Had the GigaHub replaced twice, and factory reset multiple times.

Any advice (let me know if I need to provide more details)? I've called Bell so many times and not one can help. Been dealing with internet issues for nearly 80 days now.

EDIT: Issues are possibly impacted by the amount of internet usage? I've found that when I download in high quantities, the internet only lasts 4 hours but regular usage lasts up to 2 days. Will keep monitoring this!

If this issue happens again, try performing a speed test from within the modem to ensure the connection between the modem and the remote equipment is working as intended: Speed Test.

Thank you for all your work. Out of curiosity, how many devices are connected to your Giga Hub?

Are you using a VPN? That can have an effect on specific programs. 

[LambChops713]

I have ran the speed test both in the past and recently and it never has any issues, always showing the download/upload speed.

[LambChops713]

We have about 15 devices total (including 2 wired connections and a FIBE TV box) at a time.

No VPN currently!

UPDATE: It's been 3 days now without any applications being blocked (first time since August 2025). We've been sent another modem to install in case this one fails again but so far, everything is working okay. Not sure why it is suddenly working without me making any changes.

UPDATE 2: Internet went down again and blocked apps at around 9:00pm EST. Needing to power cycle (unplug) the modem every ~2 days. Will try the new sent modem soon.

UPDATE 3: I have installed the new modem. It was working flawlessly for about 3 and a half days before having the EXACT same issues of blocking things like Discord voice chat (not text chat) and game servers. What's weirder is that I was in a voice call at the time that the internet started blocking applications. Not only did the call go on, but it only blocked me once I left the call, then tried to return to the call. A similar thing happened to games like Destiny 2, where I stayed online but was blocked from matchmaking (ie. blocked only when actively sending out a signal?).

Any thoughts? At this point, I'm pretty sad that it doesn't seem to be a hardware issue as my last 3 modems had the same problems. I'll be going back to unplugging and replugging the modem regularly for now...

Given that the modem is basically a dumb device, translating fibre signal into electrical signals, I suggest the issue may lie elsewhere. Three modems with the same issue suggest what you are seeing is upstream or downstream from the modem. 

[LambChops713]

That's kind of what I'm thinking. I think it's upstream as I've run multiple tests on my own devices and home. For example, all devices (wired or wireless) experience these issues, and there are no issues when I switch to mobile data or a hotspot.

After doing some research, I'm thinking it's related to IPv6 not being handled properly and/or the modem's NAT table not clearing properly. When I toggle IPv6 off, the modem runs with no issues for 3 days rather than for only an hour. Along with this, considering that live UDP connections to things like Discord or a game server runs fine, but new requests (ie. joining a new voice call or rejoining an ongoing call) is blocked. This might indicate that current UDP connections run fine but new ones are blocked.

In any case, I'm pretty confident it's a Bell-side issue or a firmware issue. Either way, I'm simply hoping that when I plug in my modem, I can join a simple voice call without issues.

Please run the Bell Wi-Fi app and ensure that Guard is off. Guard is cloud-based real-time protection algorithms and intelligence based on machine learning, upstream from the Giga Hub, which protect your system. You can find out more about Guard here. 

[LambChops713]

I will try this. The technician that came to our home recommended turning off Whole Home Wi-Fi and setting up two separate channels (2.4ghz and 5ghz). From what I heard, this setup does not allow the Bell Wi-Fi app to work.

I'll try turning on the Whole Home Wi-Fi again and adjusting Guard, and I'll update this post with results.

[LambChops713]

I switch back to Whole Home Wi-Fi and check the Bell Wi-Fi app. Not only was all Guard settings off, but I also checked the content access settings and for the whole home, there are no restrictions (ie. content access was not set to kid, teen or, adult).

The symptoms are getting even worse now. The modem was working with no issues for a record 5 days, then started disconnecting and blocking the applications again multiple times a day this whole week. Honestly no clue what else to try.
