WiFi Connectivity Issue - Windows 10

I have Comcast internet, and connect to my home network on my desktop via a USB WiFi adapter.

I will explain the connectivity issues I have: More often than not, certain internet applications run slow; i.e. browsing web pages, loading images, watching Twitch livestreams.

In addition, connecting to games is often affected. Hearthstone and Diablo 3 connections are often interrupted, and I was unable to get past champion select (couldn't load into the game) in League of Legends last night. Oddly enough, connecting to CS:GO games is never an issue.

However, sometimes I am able to load multiple livestreams, run a game and browse the Web with no connectivity slowdowns at all. What could be causing this disparity?! These issues have been persisting for months.

I don't know if it's Window's 10 incompatibility with my WiFi USB adaptor, if neighboring connections are affecting my internet or if I have a virus? Should I attempt to revert back to Win 8? I have been through multiple WiFi USB sticks and all show the same symptoms.

Thank you for reading and any help you provide.

Here it's all good.

So what's installed besides Windows 10? What antivirus or "HotSpot Shield"?

When I upgrade to 10 I make it a point to uninstall the antivirus and such. Then I test in a very clean Windows 10 setup and update drivers The Old Fashioned Way. That is I get my motherboard and device drivers from the makers. If we skip this step we may have a working but poor performing install.

Linksys WUSB6300 Win 10 Driver

Thanks for this. I run Avast as antivirus.

I've been doing research on my Linksys WUSB6300, and it seems that there isn't a Windows 10 compatible driver yet based on reviews/comments. I may revert back to Win 8.

Since it does work

And at times with multiple streams I fear you'll see that in other OSes. But worth a try.

Found a compatible wifi adapter

I was able to find a Windows 10 compatible wifi adapter on Amazon - Panda 300mbs. Concensus is that there aren't many on the market. Win 10 install is months old, making it difficult to revert back to 8, so hopefully this compatible adapter will do the trick.

Thank you for your responses.
