Why would Airport Express signal cut out every afternoon?

Question

I have had an Airport Express router for several years.  In the past few years, our wireless signal shuts down in the late afternoon, usually around the same time each day.  I have to unplug and plug it back in, then restart the computer for it to work. ?

Answer 1

This is almost certainly someone that is coming home about the same time each day and firing up their wireless network, or a high power wireless device, gaming console, etc. causing interference for other close neighbors. He might be using a high power antenna for his wireless network as well.
Another possibility is a nearby cordless phone which can create interference as well. I won't bore you with a story about this at this time.
When you unplug the AirPort Express and plug it back in, the Express automatically scans to find the best available channel to use at the time....and things are usually OK for awhile until the available channels get overloaded again.
If the AirPort Express is located near an outside wall of your home, try relocating it to an interior wall or room as much as possible. This will help shield some of the interference coming from networks and cordless phones at your neighbors.
Unfortunately, there are probably ten times more wireless networks than there were a few years ago, yet we have the same number of wireless channels to use that we did 10 years ago. Things are really overcrowded....an unfortunate fact of life for those living in crowded areas.
Some folks living in apartments, condos, etc are finding out more and more that they simply cannot rely on wireless, and must use a wired connection for stability.
