Slow speed on BT Fibre, Help

Paul2k12 · 8 Jun 2022 at 20:08

Hi,

Currently have BT Fibre to the house and have their 300mb service. I've got the PC upstairs so I'm relying on a powerline to supply the fibre connection. At present I'm getting rather slow downloads, downloading COD Warzone from Battlenet and its trundling along at 9mb/s. I'm just wondering whether this is normal or should I be experiencing a much faster service? Running the speedtest only gives me 60-70mb/s.

Thanks!

There's no point speed testing through powerline adapters. Sling a cable up the stairs and test again, if there's still a problem then raise it to BT.

With a 300Mbit connection what kind of mb/s rate should I be receiving?

Are you asking what the Megabytes per second number is of a 330 Megabit connection? You're using the two sort of interchangeably here and they are not the same unit. MB is megabyte, Mb is megabit. A 330Mb/s rate is ~41MB/s.

Depends on your electrics, interference and that sort of thing when it comes to powerlines. Just run a cable and get rid of the headache.

I bet it’s the power lines adapters. You only going to get good speeds over Ethernet.

As above, power lines are almost always the bottleneck. Test directly to the router and you should see a significant improvement. Assuming you're using speedtest.net then the results will be in bits, meaning your power line is limiting it to a quarter of your fibre speeds. If you can't move the PC next to the router to test, but you have a decent phone, you can do a speed test on that. May not be the full speed but I would imagine you'll see speeds on WiFi much higher than what the power lines are getting.

Powerlines usually give up at 100mb even if they are sold as 1gb.

Take the powerlines out of the equation take your PC near the router and plug directly into it and run the same test.

Historically anything sold as 600 or under tended to have 100Mbit ports, that's 12.5MB/s not allowing for overheads, anything faster always came with gigabit ports which are theoretically capable of 125MB/s.

Op, you're paying for a 300Mbit service and then choosing to throttle it by using an inferior connection to the router, run a cable or accept you're not likely to see 300Mbit over power line as all it'll support is FTTC class speeds. If you aren't willing to run cable, then other option is decent mesh, but decent mesh requires wired backhaul, so that means running cable, after that you're looking at something with dedicated radio backhaul, don't get something that shares the same radio with clients and backhaul, that's just nasty.
