I have friends and I have customers. The difference is the customers
pay me. You might try turning your friend into a customer.

Actually he has a point. Too bad he doesn't understand the numbers
involved. With high gain antennas and filters, the bandwidth of the
antenna or filter becomes sufficiently narrow to cause a slight
decrease in gain or attenuation at the band edges. Note the VSWR
graph at:

The VSWR is much better at midband (ch 6) and is slightly worse at the
band edges (2400 and 2483.5MHz). The total effect might be a small
fraction of a decibel and is hardly noticeable.

Well, he might be correct if there's something in the walls blocking
the signal to the 2nd floor, or that there's a better view of possible
sources of interference:

Foil backed insulation in the walls? Chicken wire backed stucco on
the outside?

Some medical oxygen will help. Avoid hyperventilation.

I like this homeowner. His method of spending money to solve all
problems is my kind of customer. Is he involved in government
spending or policy? Perhaps this might help.

I also have a few amulets, charms, rabbits feet, and secret
incantations that will improve wireless performance. Unfortunately,
his method of asking you to fix things without being allow to change
anything strikes me as a bit limiting. I would advise you use the
"change everything" method by declaring everything he owns and has
done to be defective. They you can sell him a total replacement
designed to maximize your profit margin. That will also allow you to
change the channel before he notices or complains.

Like I said, medical oxygen and avoiding hyperventilation will help.

Free advice is worth what you pay for it. Charge him for your advise.
It tends to make people listen better.
