My TL-WDN48000 has been working fine ever since I bought it (August 2015).

However over nigh it has stopped working as it used to and my download speed on my PC has dropped from 8MB/s (64Mb/s) to 2MB/s (16Mb/s).

There are no Windows 10 drivers availble to download, as of 12/01/2018, and I have checked that there isn't an issue with the router.

Has anyone experienced a similar problem and have a soulution?

All replies are welcome and I'd be willing to elboarte where needed.

Check this link to get the Win10 driver for the AR9380 chip. (It's a TL-WDN4800, not a TL-WDN48000.)

If you haven't compared other connected devices' performance before and after last night, though, it might be that your neighbors turned on a new router hogging the same channel and it's causing your TL-WDN4800 to use exponential backoff, making the contention window increase to as much as 1023 ms. That's going to kill your throughput. Use Wifi Analyser or a similar app to see if it's time to find an uncongested channel (if any exist).
