Weird network issue

[Probenja]

So, I have been so mad at my pc because it is unable to connect to my wifi router in my house. Every other device can connect to the router without issues but my pc can't and when it can it loads pages extremeley slow, I don't think it is my wireless card because it can connect to any other network just fine (i am tethered to my phone at the moment, unlimited 3g FTW), Also it shows no connection issues when connected to my router it just can't load anything.

The connection speed varies a lot and I am currently searching for viruses.

Also something weird is that it seems to like to create new network connections lateley, it is at "Local Area Connection 7" now and has created 3 wi-fi networks since it began with the issues.

 

 

It has been that way since a windows update which broke the wireless driver and i had to uninstall and re-install them but the wireless card has been working fine since, it is just the connection between it and my router that is having issues.

 

So, I think it is one of these potential problems:

 

1) My wireless card is being stupid (i don't want to replace it and i can't connect via cable)

2) My router is being stupid (I do have a back up one which i could try)

3) Windows is being stupid (I format my PC every year anyways but i'd like to do it in January)

4) A virus has somehow messed it up (Currentley searching for them)

5) All of the above (hope not)
