10G not working properly

[DaveB]

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

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?

[ZaneP]

Your post (here and on DSLR) is multifaceted.

So for this issue:

"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."

On the HomeHub 3000 you could remove the SFP ONT and bypass the Hub entirely. On the HH4000 and Giga Hub there isn't an ONT module: everything is soldered onto the board.

And this issue:

"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+."

Did you explicitly set the port to 10G, or is set to Auto?

"Hopefully I'll know more soon."

Please post updates on your progress!

Is your firewall perhaps BSD based? I ran into something similar. Swapping over to one of my Linux machines everything worked as expected.

ok so here is a quick update.  I did a bunch of testing using different ports on the router, and using a second computer.  Nothing was getting resolved.  In a conversation with a friend, he mentioned my cable may be too long.  I took 40 ft off the cable, and put a new connector on.  Now I am getting speeds of 2325 download, and 2260 upload.

This is what I was working towards, and it all ended up being the cable.  Thank you everyone for all your help.

A very good point. It appears that Cat6 cable has a maximum length of 180 ft for 10 Gb connections while Cat6 for 1 Gb has maximum length of 328 feet. In other words, the shorter the better!

same here, my 2.5g NIC to 10G port hh400 only runs on 1G bps. Using my own 2.5g router to my 2.5 NIC, it runs 2.5g.

[DaveB]

So as it turns out, cat6a drops speed much sooner than cat7 or 8.  This was a 100ft cable.  I took accurate measurements,  and bought a 75ft cat8 cable.  Now I am running full speeds.  

[dks]

Yes, as in navigation, distance matters. Cat6 cables are usually sufficient, but every situation is different.

You might try running the Virtual Repair Tool found in the My Bell app to determine is all is right with your profile. It is also possible you are having a issue with your motherboard not being able to handle more than 1Gb speeds. Without more information that is beyond the scope of the community, it's hard to tell. 

[ajh]

Perhaps because 2.5G is not 10G. There is no requirement for a 10G device to link at 2.5G or 5G. A $25 10G card will solve your issue.

 My systems we get  have Built In Dual 2.5 GB and use the cat 8's  bell fibe giga hub new firmware 2..13 I'm getting Mine This Tues there Doing away with the 2.11 the resue version in is messing uo it's stuck On the 1,196  they can't fix it they Took the 211 away then Brought it back Mid Augs this year they syatted rolling it out it's Oct and still having problems with it  so the 2.13 Not Widly Avaliable yet to all  but had requested it cause are software Sufi would pick it up or not .
