Location B – Spectrum noise for 2.4 GHz and 5 GHz
• Problem – Your phone system is partially wireless and
uses the 2.4GHz spectrum. Whenever someone in the
office takes a call, wireless connection speed is reduced in
the surrounding area, and to top it off, callers often
complain of white noise during their conversation.
• Solution – Give VoIP a try. VoIP will work in tandem with
your wireless network, instead of against it. Another option
is to try a phone that uses a different spectrum, or to go
completely wired for your phone service. For more on
SonicWALL VoIP implementation and capabilities, refer to

Location C – Off-network access points
• Problem – Your neighbors need wireless, too!
Unfortunately, the walls that separate you are made of
drywall. The result is that their wireless signals plus your
wireless signals equals client confusion and RF noise.
Wireless clients in this area may have trouble connecting or
keeping a connection if your channels overlap with those of
your neighbors.
• Solution – Overpowering your neighbors with high-gain
antennas is an option, but not a particularly neighborly one.
Instead, you could simply use a different channel for
wireless access points bordering this wall and ensure that
your neighbors do the same. Performance in some dual-
channel wireless devices may take a hit, but it is better than
dropped connections—or unhappy neighbors.
