Where can I have someone to set up my wifi network

If this is a home system, normally most are plug and play, you hook it up, run a disk in the computer and it works. ** even I hook them up.

But if not, there are normally adds for people who do in home computer service and groups like Geek squad do it in most major areas. In most areas there are 100's of small independent computer repair shops, most of them do it

Best Buy and Staples have tech support personal who will come to your home to setup your network, for a fee. Otherwise check for local Computer repair people.

Another source would be a local HS or college, ask the Computer Sciences dept to recommend a student who may be able to help.
