Hi

This past week or so I have been experiencing problems with connecting to our router through the wifi. The problem occurs when I immediately turn on my PC, this is connected through an ethernet cable. As soon as the PC is turned on, everything else that is currently using wifi is disconnected and am unable to re-connect to the wifi. This hasn't been a problem for the year or so I have had the PC so I can't understand why it would be the cause of it now. The router we use is a Sky broadband box, whether this helps or not I don't know.

Any suggestions or solutions as to why this is happening would be great thanks!
 
Solution
In the PC's network settings, is there any internet sharing turned on, or is there a static IP set or anything. Seems like it's taking over router functions for some reason because of a conflicting IP possibly.

Now when you mean as soon as it's turns on, like the second power is applied, or once windows is up.

If it's the second the PC turns on, then it's probably a bad ethernet port with bent pins grounding out the router, or possible even a bad cable if you haven't tried a different cable. If it's only once windows is booted up, then it could be the first thing I mentioned.

Getochkn - I've tried a new router and the problem persists so to my amazement it's the PC, have no idea how it could have happened. It's definitely once Windows kicks in. I must admit I don't really know what I'm looking for. (Windows 8) I've gone onto "View Connection Settings", gone into "Homegroup" and clicked "Let devices on this network stream my music and videos" to On and this seems to have solved the problem.

Is this a permanent fix?

Update - The wifi connections of other devices (phones etc) are dropping in and out. Still unsure how to solve this permanently.
