I recently moved into a bigger room in a shared house, and seem to have slower speeds since using my Windows 10 PC. Given the location (it's a floor above and is toward the front of the house - the router is in the living room in the centre, ground floor), I thought connectivity was poor to my TP-Link WDN4800 only receiving circa 70mb/s down out of 200. Having tried my Huawei P30, it's able to receive the full 200 on repeat tests.
The weird thing is that even with the reduced speed, it's reaching 70mb/s on repeat - no-to-little variation.
I decided to try a TP-Link Powerlink PA4010 and connect (right at the socket - not via extension cords), and weirdly enough the speed is roughly 70mb/s as on my wireless connection. I have also checked my cables and, even if they're not Cat6 as recommended by Virgin Media, the Cat5E standard seems to show possible connectivity of 1000mbps.
Granted, there may be other environmental factors at play, but given how my phone is capable of receiving the full 200mbps, I feel this issue may be more to do with my PC.
Re: PC receiving less Bandwidth than other devices
Just ran again with task manager open - just about the same if not slightly faster:https://i.speedof.me/200712182701-576 I do run Folding@Home, but only on my GPU. Granted I don't know if heat is a factor in this, but if it's CPU-bound my 3950x with NH-D15s is hardly breaking a sweat - only sitting around mid-60's with my 1070ti doing Folding. Even after disabling F@H, the result it still largely the same.
