I recently upgraded my internet connection to a fibre optic connection. I was only getting speeds of 2MB/s and was tearing my hair out, as I had been getting 6MB/s on wifi on my old ADSL connection.

I did a full reset on my Windows 8 laptop. It had been running Windows 8.1

When this finished, I ran a speed test, and was getting the download speeds that I should be. I updated all my drivers (wifi, LAN, graphics etc) and re-ran the speed test, and was still getting high speed internet.

I then ran Windows Update, downloaded and installed everything and then ran ANOTHER speed test. Now my connection speed is awful, under 2MB/s.

The hardware is Ralink RT3290 802.11bgn wifi card and a Realtek PCIe FE Family Controller for ethernet. Both drivers are up to date.

Can anyone help?
 


It is the Windows Update. My iPhone is getting the correct download speeds, as is another laptop I brought in.

The only machine which is not, is my laptop described above. If it was the connection, then logically the other two devices would also have reduced speeds.

Also, as I mentioned, all drivers are up to date, and the problem only ocurred when Windows Update had finished. The problem didn't exist immediately after the factory reset.
