So Basically Every other device in the house will get the advertised speed of 16 Mbps apart from my PC, the thing is the other devices are mostly wireless and my PC is wired with a power-line.
I've tested the power line connection its not the fault, the Ethernet port on my PC is fine I've tried its self diagnostics.
To prove the router wasn't slow I transferred a few 4GB+ files between devices on the network and as predicted they all transferred at 80-90Mbps
My PC has an intel Gigabit Nic but the BT hub is only 10/100 yet when going on YouTube videos fail to load, Facebook barley loads, my bloody HSDPA+ on my galaxy S4 is faster!?

I've also done countless virus scans on all devices in the house with nothing showing up, nothing runs in the background network utilisation shows as <5% yet every other PC gets 16MBps

Any help please!? this is extremely frustrating, thank-you
 
Are you running some kind of VPN on your main PC? Run Tracert -d 8.8.8.8 from command prompt on your PC and from one of your wireless devices, post the results.

Run a cable directly to the pc from the router and test it.

Powerlines aren't very good.

Yeh tried that still get the same thing I get a feeling it may be the router but all other ethernet ports work fine
 
3rd party AV/firewall?
Update network card drivers
Same in safemode(with networking)?

-Try a linux live disc

Replace cable.
Try another port on router.

I've got kaspersky I tried disabling it, no luck, Drivers are upto date, i'll try safe mode right now and replay with my results.

Ok ill try that also and post results in a bit.
 
Safe mode speed test results 16.13 Down 0.9 UP
non-safe mode results 1.9M Down 0.73 UP
Why is this? ^

Ping is fine, Safe mode is just essentially the bare minimum needed for the OS to start up, meaning it's good for troubleshooting.

You've probably got some network drivers that are messing with your transfer rates, I'd try to reinstall mobo drivers, if that fails to work it's probably something rogue(software/driver), which I'd say the easiest and fastest thing to do is a fresh install.

Are you sure you're using the correct Intel NiC network drivers?


EDIT:

Download and run Malwarebytes

Yeh i'll give that a go so far i've tried every other port on the router and nothing so ill do some driver re-installing like you suggested
thanks ill get back soon

I've just realised that re-downloading the chipset drivers and Lan drivers.... the download will take about "2 Hours" :/

Ok so after giving up downloading new drivers I mucked around with the intel adapter settings and i turned of "Energy Eficient Ethernet" after applying the changes the apadpter rest and suddenly 17Mbps!? i dont know how long this will last i've been getting random spikes of 16Mbps before and then back to slow old 1.7mbps :( what the hell is causing this??

Are you getting these drivers from Intel themselves, yes?

Yes these are the NIC drivers straight from the Intel website,
Also I used to have malware bytes but forgot to reinstall a while ago after a windows reinstall. I may try that but I just find it funny how after resetting that adapter and turning off energy efficient ethernet suddenly speed? Then about an hour later, slow? Same case at boot it get decent speed then for the rest of the night it's back to 2mbps.

Edit:
Forgot to mention that I can fully utilise the adapter no problem I've tried large file transfers and the adapter ran at 100mbps (receiving PC doesn't support gigabit) yet Internet fails to give me anything over 2 like said

The 100Mbps is only between your NIC and the powerline adapter; the link between the two powerline adapters will be slower, you'll need to use a specific utility for your brand of adapter to find out what that link speed is.

Well as far as I know here's how my network looks
PC is gigabit PC>powerline is 100Mbit powerline > powerline is 500Mbit router is Gigabit
The rest of the router ports are 10/100 so sending files is limited to 100Mbit
 
Powerline always run way slower than their advertised speed. They're a horrible solution to a cabling problem.

What I mean is that you're still limited by the actual link speed between the two powerline adapters; you aren't going to be getting 500Mbps so why they get away with advertising them as such, I don't know.

The link speed between the two adapters can be affected by a number of things such as other appliances that are plugged in/operating, age/quality of wiring in the house, distance between the adapters and if you're using them plugged into extension cables rather than directly into the wall socket. The manufacturer will usually supply a utility that'll tell you the actual speed you're getting.

They're not horrible at all, but they're not going to deliver the same performance as a stretch of CAT6. They're a great solution where wireless isn't good enough and installing additional cables isn't possible.
 
Hasn't the OP basically confirmed that the Powerline adapters aren't to blame in this case?

If booting into safe mode fixes the problem then it's just a software issue.
