Wifi internet problem - download speed slow
I connect my PC to my router using a wifi dongle (I wish I could use Ethernet but it's just not practical). My router is a D-Link Wireless AC1900, my dongle is an Asus USB-AC56. They connect strongly, usually at 585Mbps. My incoming internet connection is passed through from the modem to the router. The modem isn't broadcasting a Wifi signal. My internet is a fibre connection provided by talktalk.
When testing with Speedtest, my iPad, mobile phone, Macbook and other devices typically see down speeds of 40-60Mbps and up speeds of 15-19Mbps, which is roughly what they should. (I mean, I'm paying for 80Mbps, but whatever.) My PC will occasionally get the same, but very often the download is erratic and slow, something like 1-5Mbps, and I don't know how to rectify it. (The upload isn't a problem, so what I'm usually getting is an up speed that's 4-15x my down speed.)
The problem doesn't seem to be with the router or modem, given that my other devices are getting good speeds, and it doesn't help to troubleshoot through Windows because as far as my PC's concerned, it's getting an internet connection, it doesn't care about the speed, so it doesn't suggest any solution.
I have tried various combinations of restarting the computer, unplugging the dongle, restarting AND unplugging, and every once in a while after being plugged back in it starts to reach the 40-60Mbps range, but there's no consistency to it. (And I'm scared to turn the computer off because if I do it'll probably lose the speed again, but I don't want to have to keep the damn thing on all the time.)
I use Kaspersky Internet Security, which is a recent purchase, but I don't think that's the issue because I've occasionally been able to see the higher speeds while using it.
Do you have any ideas of what I can do to figure this out and get my PC to reliably see the down speeds it should?
Below is my ipconfig and Xirrus info.
