Issues with 5 gigabit card

[HMM_]

I recently upgraded to a BrosTrend 5Gb PCIe Network Card and a 3-gigabit internet plan. However, I'm encountering an issue where my computer fails to connect to the internet when the network card's speed & duplex setting is on 5 Gbps Full Duplex. It works fine on 2.5 Gbps Full Duplex. I've ensured the network card has the latest drivers installed, and it's connected using a CAT 7 cable to a 10-gigabit port on my Gigahub. Is there a possible fix for this?

Hi everyone,
Thank you for all the great troubleshooting and discussion. We appreciate you bringing this to our attention and we have taken a deeper look. We have confirmed there is an issue present and currently under investigation.
Once we have further information we will provide an update.

I'd like to know when this gets resolved as well, I bought a pair of TP-Link Deco BE65 Pro's to specifically take advantage of my 3gbit connection (BE65 Pro has two 5GbE ports and one 2.5GbE port (Using the 2.5GbE port as the WAN port until it's fixed) Thanks.

While an issue has been found, my personal position is that 2.5 Gb and 5Gb network cards have enough other issues to be problematic. I avoid them, even though they are lower cost. I went to a 10 Gb network card, which is backwards compatible with lower speeds, and have not regretted it, save that the initial TP-Link 10 Gb card died completely after one year. I replaced it with an ASUS 10 Gb network card and have had no issues since. Others may have a different experience.

I am referring to my Deco BE65 Pro which is a mesh router, not a network card in my PC. I would have to pay alot more to get the higher end version of the mesh router to get 10GbE ports sadly. I can wait until it's fixed

So I just purchased an eero Pro 7 and installed it today, and it too has this same issue. It has dual 5Gb ports and they will only negotiate at 1Gbps no matter what I do. I've tried swapping cables etc to no avail. It will negotiate properly to a physical 2.5Gb card without issue. My previous router was an eero Pro 6E with a single 2.5Gb port and it worked at that speed without issue, so the problem appears to be with the Gigahub.

[dks]

You have it plugged in to the 10 Gb port? Sounds like you have it plugged into the 1 Gb port. 

[Lexcyn]

No - read my whole message. I have it plugged into the 10Gb port and it's negotiating at 1Gb. I literally just swapped this out today and it was working fine on my previous eero with a 2.5Gb port which negotiated the correct speed on the 10Gb port of the Gigahub, but this new one with a 5Gb port will not.

Worth mentioning to rule out issues with the new eero, I connected my 2.5Gb switch to each of the 5Gb ports and they negotiate correctly at 2.5Gb - I also swapped my old eero back as the gateway and it negotiates correctly at 2.5Gb with the Gigahub. Something is messed with 5Gb.

[Edit] there have been multiple reports over on reddit of issues with 5Gb cards/ports not working so I assume this is a bug in whatever firmware Bell has. 

[Vanadiel]

Port on the gigahub does not seem to be able to sync at 5 Gbit. Instead it seems to sink at either 1 or 10 Gbps.

This can be either a firmware issue, or a hardware revision as not all SFP+ ethernet ports are capable of synching at 1/2.5/5/10 Gbps.

[Lexcyn]

Yeah seems like a firmware bug then since it DOES sync at 2.5Gb. Now do I want to wait for them to fix it or return this router and go with one that has a 10Gb port like the eero Max 7.

[Vanadiel]

Depends on what your goal is with the mesh network. Unless you consume large amounts of data wirelessly, or run multiple audio/video streams all at the same time, 1 Gbps will be all you realistically need.

I have never run into any issues with anything, and I technically speaking have 1.5/1 but practically I have less than 1/0.3 due to traffic shaping, as I prefer low latency and no buffer bloat over high speed.

[Lexcyn]

I decided to return it and get the Max 7. I just upgraded to the 3Gbps package, so I'd like to take as much advantage of that as possible (and my home network gear is all 2.5Gb now). I work from home and our VPN has a crazy overhead, so any speed increase will help me (~70% reduction with it enabled so going from 1.5 to 3 will help a bunch).

[Vanadiel]

You should be all set for the future then!

Can you tell what the issue is? Is it on the Router or is it something else? Was there a fix deployed?

[dks]

Thank you for your question. Bell staff have indicated in the green-checked helpful replies that an issue has been identified and a solution will be announced when it is available. That may come in new firmware. 2.13 the the latest Giga Hub firmware. Nothing newer is available yet. Resolving such issues can take time, as Bell does not write the hub firmware. I believe new firmware comes from the device manufacturer to Bell.

Just a heads-up — I’ve been through it all: BE65, BE65 Pro, BE75, BE85. The BE65 Pro was a nightmare. Neither TP-Link nor Bell could help, and PPPoE didn’t solve anything. Surprisingly, the basic BE65 from Costco has been rock-solid (though limited to 2.5Gbps). I returned the Pro after grabbing a BE65 3-pack from Costco USA for $399. Now I’m testing the Eero Pro 7, but it’s capped at 2.5Gbps via the GigaHub’s 10Gb port. The only time I hit full 3Gbps was through another Deco with a proper 10Gb port — looks like the Sagemcom GigaHub doesn’t support 5Gb at all.
