wifi connection fails every few minutes

[Ed J]

I've read the sticky and tried some of the possible solutions but I cannot get this issue fixed. It'd definitely not my network or a hardware issue. It seems to be identical to many others having the same issue but I can't figure out the problem.

I've tried different brands of Wifi adapters, my signal strength is good.

If anyone has any suggestions it would be nice.

I've attached my wireless-info from the script as directed in the sticky.
Here is an excerpt...
