10G not working properly

Contributor II

Hello all!!

I have been a happy Bell internet customer for a while now (15+ years).  I just upgraded to the 3GB plan and the tech just came and installed the modem.  My desktop computer has a build in 2.5GB NIC, and I have a CAT6 cable from the 10GB port on the modem, and plugged directly into my 2.5GB card.  I am getting unexpectedly low download rates.  Ookla says my download is 140.07 Mb/s and upload is 881.22.14 Mb/s.

When I plug into one of the 1G ports I get better results.  When I plug my laptop into the 10GB port (it only has a 1G NIC) I get similar results as my desktop.

I have firmware version  1.16.5

I have tried removing the NIC from the device manager & updating the drivers.  

While the tech was here we were not able to get it working.  The really weird thing is he even went and got another modem from his truck and it had the same result.  I have tested sppeds to the modem in the modem console page and the modem is getting 3GB+ speeds.

Are there any known problems with these ports? is there something I can do to fix this?

TIA

David

One piece not mentioned is the network cable. Is it possible that the network cable is bad? I quick test with another network cable, even a short Cat5e cable, might tell you something. If the speeds remain as you post, it is not the cable. The fact that you can get a 3 Gb speed test at the modem suggests any issues are not with your profile or (possibly) the modem.

I previously had a CAT5e cable installed, which should be rated for 1GB I believe, but was getting the same speeds.  I thought it might be the cable, so I went out and bought this CAT6 cable with same results.  I have a 1GB NIC laying around, I'll try installing it and see if I get better results.

I just followed your instructions.  didn't help the download speed, but upload went up to 1.2 Gbps

Interesting. Not sure what to make of this.

That is a really good thought. Keep us posted.

Hi there @DaveB

While having 30 years of Intertnet engineering experience doesn't preclude me making a blindly stupid error I am fairly sure that I have tried everything at this point. The behaviour of the GigaHub is at best inconsistent, sometimes the advanced DMZ works, sometimes it doesn't, but this is probably not relevant at this point but it bears mentioning just in case.

Using PPPoE pass-thru on either a 1G or a 10G client port and connecting to the 10G port on the Gigahub I see speeds of 300-400Mbit on a speed test. The exact same configuration but connected to a 1G port on the Gigahub and I reliably get 980Mbit+.

After replacing the cable with a certified Cat8 cable just to be sure, no change. I checked the sync rate reported on both ends and it reported as 10GbaseT-SR Full Duplex on both ends, DHCP completed fine as expected. Speeds still 3x faster using one of the 1G ports. I then replaced the SFP+ and even selected a different brand thinking it might be internal to the SFP+ and zero change.

This does not make sense. When I try to use Advanced-DMZ as I intend it gets even weirder but I'm suspecting something in the GigaHub is caching some bit of information and causing issues or the implementation is just flaky as it either works on a 1G port, doesn't work on any port if I switch ports around, and when it isn't working properly if I reboot the GigaHub it comes up, works for 4 seconds and fails.

Again, to me this does not make sense. The rest of my network here is happy to be pushing 95% of the 10G available locally without issue. Connecting the same WAN interface to a simulated network has it working at full speed just fine.

Some red-flags, the Systems Logs most recent entry is dated 2013-01-01 which seems wrong.

Current firmware version is 1.16.5, Hardware version 5690-000001-000

If they simply sent a registered XGS-PON SFP+ instead of this ridiculous 'modem' none of this would be an issue at all, in fact I was incorrectly informed that was what they did, inside the GigaHub, but of course only the earlier models did this.

Does anyone have any idea what is going on? Is their 10G some odd version that requires special settings on the client end?

Hi @ajh 

I saw your initial and follow-up posts on the Bell forum at DSLR. Would you mind updating here the latest reply you posted there? That way we're all in kept in the loop.

Thanks.

All I can confirm at this point is it isn't entirely Bell's fault. It probably is, it probably is the GigaHub doing something stupid combined with the client sticking to the standard, but at this point I've confirmed that Linux doesn't have the same issue with the device, but Linux tends to be much more permissive when it comes to standards compliance on the side of 'making it work'. Hopefully I'll know more soon.

I haven't had problems with the ports. Did you manually set the 10G port to 10G, or is it set to Auto?
