Re: 2.4 GHz Comments and Proposals



And in my case,  that is EXACTLY what happened.   I had 2.4 GHz house 
phones.  I installed WiFi and the phones or wireless Lan would 
alternatively collapse. You cannot believe how utterly stupid I felt 
when I realized what was happening.  I replaced the phones at ridiculous 
cost  on the 5.4 GHz band and the problems vanished over night.
