Installing And Troubleshooting Wireless
Network, & Properties Of Dhcp
2.2 Given a scenario, install and configure
a wireless network.
When installing and configuring a wireless network, you
need to remember the following:
Driver Compatibility - It is important to make sure that
you have installed the correct device driver for your wireless
Low Signal Strength - There are a number of factors that
can cause the signal of your access point to deteriorate
and the performance of your network to fall under par. Practically
any appliance that operates on the same frequency level
(2.4 GHz) as 802.11b or 802.11g can cause interference with
your wireless network. Be sure to keep cordless phones,
microwaves and other electrical equipment at least 1m away
from the access point. Try changing channels on the access
point and test it out on one of the clients.
Access Point Location - You may also want to try changing
the position of your access point antenna to improve performance.
Installing a repeater for a performance boost:
If you're looking for a boost you can always choose to
install a repeater. The job of a repeater is to receive
the signal, regenerate it and rebroadcast it therefore extending
the range of your wireless network. This would sit somewhere
between your Access Point and your wireless client.
Changing the Antenna:
Changing the antenna of your access point can increase
signal range and overall performance. Typical access points
come with a 2dB or 4dB gain antenna but there are one's
available with higher gain. Antenna gain is measured in
dBi (decibels-isotropic) which basically means how powerful
the antenna is and how far it can provide a signal. .
There are three main categories of antennas:
