How old is his computer? If older than 2 years, tell him to buy a new one. That may at least take care of the computer problem.

Show him articles like this that illustrate that products today are fallible and constantly have issues.

Keep in mind that Wi-Fi can be affected by wacky stuff. We had a client that was losing Wi-Fi connection (but the wired LAN would stay up) with L***l equipment and some other posters mentioned that they ran into the same issues when there were Honeywell security pieces in place. When we checked, our client had Honeywell.

If you want to troubleshoot this wacky stuff, also keep in mind that Access can design a system that allows you to troubleshoot this stuff to the nth degree. It costs $35K+ but it allows you to figure out what you need. Our first Access project really opened our eyes to the visibility of their products AND how expensive this stuff can be if you want it done right.

Without knowing you or your client, I'd say with 99.99999999999% certainty that the good doctor won't even consider a five-figure network. However, it's good to know (it was for us at least) that when their are issues with a bad wallplate, STP, Honeywell, RF noise, etc. that it can be diagnosed if the client really wants/needs to figure it out.

Good luck
