I recently had to re-boot my router and now my wireless connection doesn't seem to work how do I set up my wireless again

You will have to log in as the admin on your computer, then there is a site online for your router (I use a dsl router) you can then go there, connect your router to your computer that way. That's the best help I can give.. I usually get someone else to set up my router

Which company router you have ?
So try to search in Google of that and reconfigure it as it give full steps HOW TO CONFIGURE YOUR ROUTER?
