I've had more than 10 technician come to our place to try to resolve our issues. None have been successful. They all repeat the steps prior technicians have done, and nothing changes.
On a 750 plan, I receive inconsistent speeds that range from 10/10 (upload in mbs/download in mbs) to 200/250. The upper end is extremely rare. I would say the average tested across MANY devices in the home are about 20/50. I also seem to get frequent dropped signals on both 2.4 ghz and 5 ghz bands - the 5 ghz is the worst. Occasionally, I can't even stream YouTube music on my computer! I signed up for Telus 750 to stream. That's an impossibility with 30-60% dropped frames due to poor internet connection.
It's an extremely frustrating situation, to be sure. We've had 750 for almost 6 months now and have been struggling with lower average speeds than my brother gets out on his farm. The most recent TELUS tech came today and says he can't find a solution, so he will tell TELUS to downgrade our internet plan. I don't want a downgraded plan. Downgrading my plan will not solve the problem, it will just mean I pay less for the same inconsistent and super slow speeds. I'm hoping someone out here has an idea. My best guess is there's something happening to reduce the speeds from the Fiber in -> ONT, but Telus ensures that the ONT is getting the correct speeds. Any ideas?
You can also connect a computer directly to the ONT - e.g. a laptop connected directly to the ONT with a short CAT5 cable - set the computer to DHCP and it will pull an IP address - then test the speeds. This would eliminate everything except the ONT and computer from the equation. If you are sure that the computer can operate at gigabit speeds (for instance it operates correctly internally on your network transferring data at gigabit speeds with other devices on your network) and you still don't get the full 750/750 up and down then the problem lies with Telus equipment or the fibre line itself. This is a basic troubleshooting technique - eliminate everything you can from the picture until you get what you want - and then add equipment back into the picture one device at a time until the error happens again - and then you know where the problem lies. I would also ask Telus what evidence they actually have that the ONT is receiving the full 750/750 speeds. I can't remember where Telus does the rate limiting for your subscribed speeds (at the ONT or at the switch/router at the other end of the fibre line) but they can certainly change the speed on the fly so they could even experiment with different rate profiles as a troubleshooting technique.
Just a suggestion: check your firewall settings on your computer. I was getting slow speeds to my gigabit hardwired desktop computer. Upon further testing, I had Symantec Endpoint Protection installed with the "Denial of Service (DDoS) Protection" setting in the firewall enabled, and once I disabled it, my speeds returned to more than 750mbps.
I've had the same issue with mine and tried many of the same fixes as you. I found using a VPN actually helped a lot as it seems that the dynamic IP settings of the router we have send our signal all over the place. I spoke to a tech and they said to either use a third party router or try getting a static IP, I haven't tried either but am about to give a third party router a go and see how that works.
