WiFi Signal Fluctuatews Wildlt

I have a client who is having awful WiFi performance.  if he takes a laptop (he has two) or a WiFi device (Kindle and iPad) more than a few feet outside his office the signal can go from five bars to three.  Or three bars to none, meaning it disconnects from the network.  He's going nuts.

We've replaced the router (now an lEA4500 with the latest firmware).  We've tried an extender (RE1000 I think).

It's a very large house on a very large lot.  It's not a range issue sice this hapens within 20 feet of the router.  No obvious sources of RF interference.  Standard wood frame construction.  No people or devices hogging bandwidth.

I'm stumped.

What is the make/model of the laptop? What is the network adapter and driver version?

I use WirelessNetView http://www.nirsoft.net/utils/wireless_network_view.html to see what other WiFi networks are possibly interfering.  In addition, a wood frame house can have wire mesh supporting some things like the outside stucco.  Refrigerators and stoves and other metal appliances can cause problem also.  If the devices will support it, you can change to the 5GHz band which is usually less cluttered though metal will interfere with it also.

You can try changing the wireless channel - sometimes a different channel will work better.  The best, non-overlapping channels to use are 1, 6 and 11.  I found changing to 11 increased the range in my house.

They are Samsung Ultrabooks, which I know have issues. The drivers are current. But it happens with phones, a Kindle, and several phones.  No strcture or appliances. Changed channels and frequencies. It's crazy.

Did you try WirelessNetView to see what other networks are there?  There are other possibilities.  One is that you may have ended up in the line of sight for a higher powered point to point network that works on the WiFi frequencies.  Any industrial buildings nearby that might use high powered microwave ovens?
