Tom, Very interesting suggestions. I will forward your suggestions to the wifi contractor who has not yet had a chance to come to our site to check out the problems. Would the interference just affect the connection without affecting the signal strength? We do have some welders in the

This is outside my area of expertise but from what I know, my guess is that are going to need a lot more equipment/ access points, repeaters etc and the assistance of an experienced, credentialed consultant/ contractor. Steel in building is a real problem and so can be the architecture of the

We have a contractor who has set up a wifi network in our large 3 story art center which is an old building filled with concrete walls and columns. He has used a Sonic Wall router and so far 2 access points. The signal seems strong most of the time, at least if measured by the bars
