Hey everyone. Turned my computer on today to see that my speeds have dropped from 70s to 0.05mbps. Im running on win7, 64bit. My wifi is working normally on all my other devices.

Ive run malwarebytes and my anti virus but nothing came up. Ive also tried restarting the router, and flushing the power from my computer as i saw in a different post. Nothing has fixed it yet.

I just tried plugging the ethernet cable into my laptop and i did get 79mbps so im not sure why my computer is having an issue, any more ideas? I can provide more information if needed, and sorry in advance for not really knowing what information to add, this is my first post.
 
Solution
Try swapping out the network card in your PC with a new one - - it may be that existing one has developed a fault.

Trial and error at this early stage so that's one thing to try for starters.
