Re: WiFi question

[GuidoZ <uberguidoz () gmail com>]

A very good point indeed Mark; one that shouldn't be dismissed even
WITH common SSIDs. Other technology clashing with WiFi certainly isn't
new... in fact it getting worse!

Besides motion sensors, also look for wireless phones, security
systems (like ADT's window/door systems - they use wireless to
communicate with some systems), things like that. With the amount of
wireless technology out there, it's becoming less and less common to
find unaffected WiFi.
