10G not working properly

DaveB — Tue, 13 Jun 2023 14:40:18 GMT

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

Test between two computers on your local network first. That will give you a baseline network performance for your LAN. You may not have another computer with a 2.5 gpbs port, but you might have another with a 1 gbps ether port. That would help establish a baseline.

I get 900+ mbps from a mac mini connected to any port on the GigaHub via two ethernet switches (so a good quality switch, in between you and the gigahub, has no performance impact). It is exhausting the limits of a wired gigabit ethernet connection. I have other, lower performce, computers with wired gigabit ethernet ports that struggle to get 200 or 300 mbps. The difference is the speed of the cpu, the particular ethernet hardware, the quality of the device drivers, the OS, etc.

What would be the best way to test between two points? is there software to test for this?

If you want a Windows application then search for "network lan speed test software windows free". There are few out there, although I've never used of them, Basically it's going to be a simple program that you install on two machines and it blasts data from one computer the other.

I usually just use "scp" (secure shell copy) on the command line to transfer an enormous file because it reports the transfer speed as part of its normal operation. Not something that a casual user would be familiar with. Also it encrypts the data it sends so if your cpu is slow you'll be measuring your cpu's encryption speed not network speed, and you have to be certain you storage devices at both ends are much faster than your network connection. Not ideal, if you truly want to isolate network performance.

The maximum speed possible on a 1 Gb internet connection is, I believe, 940 mbps symmetrical. The difference between that and 1 Gb is overhead. If the speed of the wired connection is lower, i.e. around 100 mbps, then the speed of the card is lower. I agree, the quality of your equipment matters. Buying low cost equipment or ordering from offshore may save you money, but quality may also be less.

Thanks DKS, I am testing on the simplist config possible to make things easier, so I have removed all switches between the modem and my PC. My PC has had a hardware upgrade lately, and I am running a 10th Gen I5 and an onboard realtek 2.5GB NIC. Cat6 dirctly from that nic into the 10GB port on the modem. I still have to test a port to port transfer to see what I am getting, but from an internet spped test I am getting poor results.

A suggestion to start with is that you run the Virtual Repair Tool. It would appear that your profile might be off. The Virtual Repair Tool might be helpful to resolve that or tell you if that is on track. You can start it here: https://mybell.bell.ca/VirtualRepair

Just to be on the safe side, make sure you don't have a VPN choking your connection somewhere in the mix. Many of these are voracious bandwidth hogs.

Re: 10G not working properly

DaveB — Mon, 03 Jul 2023 15:18:12 GMT

OK so here is the latest update.

1. I have no VPN running while testing. I very rarely use it at all.

2. I tried the virtual repair tool, and it tells me there is an issue and will connect me to tech support. They start chatting with me, and go through the scripted responses. They eventually call me becuase they keep resetting my modem so they can change the speed profile. I have managed to get it up to ~300Mbps download, and the upload is staying strong over 800 Mbps.

To confirm the setup - Gigahub connected Fiber to the router. CAT6 cable connected to 10GB port, then directly into my PC on the 2.5GB port. Very simple, no switches, or anything in between.

The frustrating thing is this connection can obvioulsy at least the 800+Mbps upload, to get it to download at that speed would be nice.

I am simply just confused why I am not able to get more around 1.5GBps. Paying for 3GB line from Bell, and connections support much better speeds.

That's frustrating. I'm on the 1.5G plan and get around 1.6G down and just over 1G up. I know that very few real-life files download or upload at the speed of test packets, if any. I also know that Bell's commitment is for "up to" the bandwidth specified in your plan. But come on, your "way below" predicament is abnormal. If Giga hub checks ok that could mean some issue with your computer's network configuration. First thing I'd do is clear the DNS cache in case you haven't done it already. From the command console just type "ipconfig /flushdns" without quotation marks and see what happens, ya never know.

There are other net config settings to consider but, not knowing whether you already tried them all already I won't launch into those for now. I suspect that since you know your way around a router then you know how to configure your computer accordingly. This is merely to eliminate the computer from the list of suspects to blame for your network speed issues.

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.

Re: 10G not working properly

DaveB — Tue, 04 Jul 2023 13:17:06 GMT

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.

Re: 10G not working properly

DaveB — Tue, 04 Jul 2023 13:21:33 GMT

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.

10G port slower than 1G port on Gigahub

ajh — Sun, 23 Jul 2023 22:35:10 GMT

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.

ajh — Mon, 24 Jul 2023 15:33:13 GMT

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.

Re: 10G not working properly

ZaneP — Mon, 24 Jul 2023 16:49:03 GMT

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