Giga Hub 2.0: PPPoE passthrough/2nd PPPoE session capped (average 330 Mbps) on 3 Gbps plan

[Velaris]

Hello,

I'm on a 3 Gbps plan and I'm seeing a repeatable/hard throughput cap only when using PPPoE on a downstream device (PPPoE passthrough / second session).

My setup:

- Bell Giga Hub 2.0
- Downstream router: UniFi Cloud Gateway Fiber (UCG-Fiber) connected to the Giga Hub 10G port

What works:

- If the UCG-Fiber WAN is set to DHCP (e.g. behind the Giga Hub 2.0/double NAT), I can reach full speed (~3 Gbps).
- If my PC is behind the Giga Hub 2.0 on DHCP, my PC (1GbE NIC) reaches the expected ~1 Gbps.

The problem (reproducible):

When I establish a PPPoE session from a device behind the Giga Hub, throughput is capped around ~300–330 Mbps.

Repro 1: PPPoE from UCG-Fiber

- UCG-Fiber WAN set to PPPoE using my b1 credentials
- Result: ~300–330 Mbps (repeatable), despite 3 Gbps plan

Repro 2: PPPoE from a Windows PC (bypassing UCG-Fiber)

- PC connected by Ethernet to the Giga Hub 2.0
- PC NIC: 1GbE, cable: Cat6A
- Created a Windows "Broadband (PPPoE)" connection using the same b1 credentials
- Result: same cap at ~300–330 Mbps (repeatable)

Because the same cap occurs even when PPPoE is established directly from a PC (*no* UniFi router involved), it points to the Giga Hub 2.0 PPPoE passthrough / secondary PPPoE session path rather than my router.

Can you confirm:

- Is this a known issue on the Giga Hub 2.0 (firmware-related)?
- Is there a firmware update or hardware replacement option to resolve PPPoE passthrough speed caps?

Thanks

Hi everyone,

Thank you for reaching out to the Bell community about this.

We wanted to pop in and confirm that this is a known limitation, and a solution is currently under development. 

We’ll be sure to communicate any new updates when we’re able to.

Have a nice day 🙂

Great to hear for GigaHub 2.0 users, but will this also be applied to the HH4000?   I experience similar symptoms when using a PPPoE connection on a UDM.    I observe 100% CPU on the HH4000, high latency (200-500ms) and occasionally dropped packets.     When using DMZ, the cpu on the HH4000 is 40-60% and stable.

Is there an explanation why this has happened now on setups that have been fine using PPPOE and the Gigahub 2 for months, upwards of a year? Has Bell rolled up an update on the Gigahub 2 recently to break our setups?

Hey there, you guys acknowledged this bug back in November 2025, There is still no fix yet. What's going on? What's the alternative? Customer service says They cannot downgrade me to Home Hub 4000. Which is very inconvenient resolution.

Thanks for your question. Bell does not announce firmware updates or provide Release Notes. The current firmware version is 3.11.3, I believe. Bell also does not change modems other than to replace what you have or migrate customers to the most recent model, if possible.

What has been done on this front. As of may 5th (I have Logs!!) my internet from 3rd party hardware has been capped at 300/300. This is a known issue they you are exploiting and or using deliberately to handicap Paying clients internet service!

[SanthoshV]

100%. These reports date back to September 2025, they acknowledged this issue way back then. But are refusing to do anything about it. I called the executive department and asked them to send me Giga hub 1. May be that should work fine for me. It will arrive in couple of days, will let you know.

This is around the time when my PPPoE setup became unusable. 

In my desperation I turned PPPoE off, and Dynamic IP on my TP-Link AXE300 router settings. I believe I'm back up to my maximum bandwidth right now like before.

I can imagine exactly what kind of person(s) is directly responsible for causing and not fixing this kind of problem but I found a TP-Link fourm post about setting the MAC address of the 3rd party router/firewalls wan port under DMZ (Advanced DMZ) and then setting your 3rd party router to DHCP instead of PPPoE. That gets me closer to sold speeds by bell but at this point if you can bypass the ISP router as a whole that would be the route to take😉(DO NOT LOOK INTO FIBER ONCE UNPLUGGED. DOING SO RISKS EYE DAMAGE!!!). Bell Canada should be embarrassed at this joke of a service they keep charging more and more for and this makes it so I will no longer recommend Bell in any way, shape or form. Great job guys, you lost a loyal client and future clients to come👏.

Advanced Tools & Settings -> Under DMZ setting -> Turn on DMZ and Advanced DMZ option -> Set Mac address to 3rd party router/firewall WAN port.

[3rd Party Router/Firewall]

Disable PPPoE -> Switch to DHCP -> Reboot device -> Speed test your network because you can trust these guys anymore.

Special Thanks to: RobotG. TP-Link Forum Guy. UniFi SLA logs🫡. Other parties doing great work, you know who you are 😉

Thanks for your question. Once you have the GH 2.0, Bell will not "down grade" you to an earlier device, to the best of my knowledge. If they do, please let the community know. @BellPatricia has provided the latest information available regarding firmware.

Hi, while you think this setup is seemingly good. There is still double NAT happening. You'll see instagram buffering, youtube tabs crashing. Rubberbanding in games, packet loss randomly. Pppoe is the best way to bridge them

[SanthoshV]

I'm currently using Giga hub 2.0. I spoke to executive team yesterday, and the manager said he would be sending me the gigahub 1, once it arrives, I'll test the pppoe and update here.

Pretty frustrated user here.

All started with the most recent Giga Hub 2.0 firmware breaking port forwarding, essentially destroying my ability to connect to my home Plex media server on my own network. After some useless conversations with "tech support" I learned that port forwarding is an "unsupported" feature. Even though the option exists in the hub and can be edited. 

Was forced to buy a 3rd party router to "fix" this problem. Which I've now connected using PPPoE and my media server access has been restored. But now I've crippled my plan speeds from 3GB to 1GBps. So I got screwed first by wasting money on a 3rd party router because of a feature Bell broke in their latest firmware. And then now with losing 2GBps speed that I'm paying for because Bell has capped their PPPoE speeds. Thanks Bell.

A cap of 1 Gbps could be due to your routers inability to support speeds higher than 1 Gbps on it's LAN ports.

Does your modem supports speed higher than 1 Gbps on it's LAN ports?

Another reason for the cap could be PPPOE processing capabilities of your router lacking the ability to support packet rate speeds over 1 Gbps.

I would start looking there to troubleshoot.

[Lundon44]

Thanks for the reply. 

My router is the Asus RT-BE88U which supports up to 10GB speeds. My PC Ethernet cable is directly plugged into one of the 2.5GB Lan ports. Bell has capped PPOOE speeds to 1GB regardless of whether or not I'm capable of higher speeds. I can bridge through the DMZ method instead which may allow for better speeds but then I've heard of instability issues that come with that.
