Why does my internet connection stop working when I get a phone call? OR
Why does my phone not work when I am near my computer?

This is a problem that generally stems from having a certain type of cordless phone, and a
wireless router. Fourth generation cordless phones and wireless routers (along with other
equipment such as microwave ovens and baby monitors) transmit on the 2.4GHz radio wave
range. When devices on the same frequency operate closely together, this can cause
significant interference and even prevent some devices from working. Because of this
limitation, many phone manufacturers have switched over to using the DECT (1.9GHz) or
5.8GHz phone ranges, to allow for better interopability between devices. If you do have
one of the older 2.4GHz phones and a wireless router, we would reccommend that you place
the phone base and the router as physically far apart as is reasonably possible for you,
preferably not within 10 feet of each other.
