I apologize in advance for the length of this description. For two years now I have been trying to figure out what the problem is and am about to give up and try Bell fibre as it may be the only way to rule out my Rogers feed line.
Here is my situation, I have Rogers 1Gbps service to a home, the tap is in my front lawn 20 meters from the home. The line comes from the tap to the home and goes through two connections directly to the CODA modem, no splitters etc. This line from the tap to the home has been checked by Rogers and they say there is no issue.
When I do a speed check with a direct connection to the CODA using an I7 multi-core PC windows 10 pro I get 150/30 Mbps speed. The 2.4 ghz wireless gets 25/30 Mbps and the 5 ghz wireless gets 50/30 Mbps.
Rogers line maintenance has come and say that they get 900/30 Mbps at the tap in the front lawn.
I have done speed tests using 4 pc’s and 2 mac-books all get less than 200 Mbps speeds. I have run speed tests using new android phones on both 2.4 and 5.0 and get less than 50 Mbps on both spectrums.
So to date here are some of the things I have done to try to figure out what the speed issue is:
Here is what I get for my 1Gbps service:
I am at a complete loss to know what to do next. I know this, with any of my PC’s directly wired fully updated I get less than 200 Mbps, if I boot into Linix I can get 900 Mbps using firefox. I know that wirelessly either 2.4 or 5.0 I get less than 50 Mbps using android phones. Apple mac-book gets 100 Mbps wirelessly. Android TV will get either 700 using Ookla app or 75 Mbps through browser to Rogers speed check.
My speed problem is on Windows 10 professional machines unless I boot into Ubuntu where I get full speed. But the speed problem is also on Apple mac-book, and the speed problem is on android phones. The speed problem on android TV is there if using a web browser but not when using an app.
I am at my wits end with this, if anyone has any ideas it would be very much appreciated.
Good morning @mikemeddings1!
Welcome to our Community! This sounds like it could be a complex issue to resolve so you've come to the right place for help.
The fact that your wired PC gets near optimal speeds in Linux but not Windows is interesting. Since our techs are able to get near optimal speeds using the same Ethernet cable in your home, it honestly does seem like there is an issue with your equipment. I don't believe it's necessarily a hardware issue though, otherwise, your PC should get similar speeds no matter which OS you use.
This sounds like something @Datalink would enjoy puzzling out!
Flapping is another concern but that should impact all your equipment equally, so I don't think that's the root problem here. Regardless, I would feel much better if I checked your account to ensure the flapping is being addressed.
Thanks for the reply sent a pm. Simply cannot buy that it's a hardware PC issue as it shows on 3 other PC's and a 4th machine is a Macbook, totally different eco-system.
@mikemeddings1, I don't have time at the moment to address this, but, for now, can you drill down into the advanced settings for the Qualcom nic, list those and their current settings in a post.
Can you also check the driver version for the Qualcom nic. Is it running the official Qualcom driver or did Win Pro replace the driver as it wants to do?
Can you also have a look at the device manager, drill down to the Qualcom nic and copy the entire model number and paste that into the post.
If you only have the Qualcom nic equipped pc connected to the modem, with the wifi disabled, do you still see the slow speeds when you run Win 10 Pro?
Hello Datalink, I can certainly give the Qualcom wifi information if you wish, but as when I check my speeds I use the Ethernet connection so maybe this would be more useful? Think to trouble shoot the Ethernet then the wifi speed may follow.
The Ethernet uses a Realtek PCIe controller the driver is from Realtek for windows 10, hopefully the following is what you are asking for:
Datalink, don’t know if this is the information you are asking for hopefully I haven’t exposed my system too much. As I may have said, normally when I am looking to see what my connection speeds are, I disable the wifi and connect a Cat 6 cable to the CODA. To be honest there doesn’t seem to be any difference in the Ethernet speed with the wifi on or off, it’s always between 100 to 175 Mbps max, the wifi side is even worse as this card is only a 2.4 ghz card but it is often less than 10 Mbps. I have a Dlink USB Ethernet adaptor that I have tried in the 5 ghz and it is not much better, maybe 50 Mbps.
When the chronic care tech showed me that his laptop was able to get 700 Mbps and when he said the problem was my hardware I just kind of accepted it as fact. But since I have tried 3 other laptops 2 of which had similar speeds as mine. One of the 3 got 750 Mbps adding confusion to the mix for me. It is beyond me to understand why when I boot into Linux I get 900 Mbps. Also how my android TV box can get 700 through an app, but when I go to Rogers speed test in chrome it is less than 50 Mbps.
Ok, can't see the images yet as one of the mods has to approve them. So, do I understand this correctly, the motherboard has a Realtek ethernet controller and port. If so, then this does make sense unfortunately. We've run into issues with embedded ethernet controllers in the past, and ..... they always been Realtek controllers. Its too early to say this yet, but one solution is to install another non-Realtek NIC. My current thinking is that there might be some setting in the NIC adapter settings that might be causing some heartache with the modem. I'm thinking perhaps of Jumbo-frames, which should be disabled, but, I'd like to see the other adapter settings as well and what they are currently set to.
Edit: can you have a look at the back of the modem when you have the pc connected. The connected port LED should be flashing Amber, indicating a 1 Gb/s connection rate with the connected device port. Flashing green indicates 10/100 Mb/s. I'm wondering what that LED indicates when the pc is running Windows instead of Ubuntu.
try download a torrent file from a known fast seed on windows and see how fast it goes
I use qbittorrent
Datalink thank you again. Yes it is a Realtek ethernet controller and port, Jumbo frames are "disabled" always have been for speed testing and is the normal setup. The card is cabled to the CODA and the CODA connection at the back of the modem flashes yellow. The card shows 1000 Mbps service.
What I fail to understand as well is how two other laptops only every get maybe 150 Mbps speeds. Equally well why when I boot into Ubuntu Linux can the same card provide 900 Mbps speeds?
Also I fail to understand why on the wireless side when the tech was here he had a Samsung S9 and on the CODA's 5 ghz he could get somewhere around 350 Mbps, my phone Samsung S7 gets 30 Mbps on 5 ghz. When I use the DLink USB 5Ghz wifi card I still only get maybe 75 Mbps.
To your last question in Ubuntu Linux, the connection is yellow as well.
Thanks in advance
I have tried to download a ISO of Linux and using bittorrent the download speed hovers at 120 Kb/sec.
