Desktop experiencing SUPER SLOW download speed! HELP PLEASE!

[Kaine anderson]

It's a self-built computer, I'll give you hopefully necessary details:

ISP: Utility Warehouse
Connection Type: Unsure
Router: Technicolor TG582N

MOBO: AS-Rock H81M-DGS R2.0
PSU: XFX - 550W Core Edition 80+ Bronze

OS: Windows 7, I think my drivers are up to date...I think.

Netgear N300 Mini Usb Wifi Adaptor

Hopefully that's the required information, so here's the problem.

I live in a block of flats, top floor. My room initially was a dead zone, so I bought a TP-Link wifi range extender so I could connect to our router. My phone gets 5 bars and so does my desktop, but my desktop only reaches 0.3-0.4 MBP/S, when it should be hitting 8-15ish and my phone hits around 6.

I took my desktop through to the room with the router and plugged it directly into the router via Ethernet cable. It had a burst of 8MBP/S (online speed test). Then I tested the wifi, while still plugged into the router, and it went back down to 0.3MBP/S, so I took out the adaptor, re-tested the connection with the Ethernet cable and still 0.3MBP/S. I've tested my speeds when no-one else has been connected but me, so just 1 other device, yet still 0.3MBP/S. I'm losing my stuff here guys and need some serious help. All other devices work PERFECTLY, we have multiple consoles able to play simultaneously with very little lag.

I recently moved to this flat for university, but when I was living at home and in my previous flat, this same computer experienced no issues like this.

Anyway, thanks to whoever helps me

For WiFi performance, this is probably your issue:
"Netgear N300 Mini Usb Wifi Adaptor"

Those little WiFi adapters are less than optimal. There is only so much antenna you can squeeze into that little tiny box.

Consider a PCI-E Wifi device, with actual antennas hanging out the back.
Or preferably, an actual ethernet cable.

Thanks for the response. However I have tried connecting an Ethernet cable from my computer to the TP Link and on a seperate occasion to the router and it still only gets 0.3MBP/S?

Connecting directly to the router with an ethernet cable, what do you get?
We work backwards from there until it fails.

Well, when I first plugged it in to the router, it got 8MBP/S. I kept the Ethernet cable in, but then plugged my adaptor in to test the Wi-Fi speed, it got 0.3MB. So I thought it was a Wi-Fi error. But when I re-tested it directly after that with the Ethernet cable, it went back down to 0.3MBP/s.

Disconnect the WiFi, reboot, and see what you get.

Disconnected the WiFi, turned the router off too. Rebooted. Waited, turned router on, logged in, same speed.
