2-7-6 Security Tips for Wireless Network
Here are some quick tips to help you improve the security level of your
wireless network:
1. Do not use 100% radio output power unless it's necessary; higher
output power means border wireless coverage, but if you're not using
this wireless router in a really big space, you'll let your neighbors
have the chance to do something bad to your network. If the wireless
router is not far away from your computer, try to start from 10% Tx
Power setting in 'Advance Settings' menu, and only raise the Tx
Power setting when it's required.
2. Never use simple words (like school, apple, computer) as WEP
encryption or WPA passphrase.
3. A complicated (the combination of number, alphabet, even symbol,
and long enough) WEP key and WPA passphrase is much safer than
simple and short ones. Remember that the wireless client is capable to
keep the key or passphrase for you, so you only have to input the
complicated key or passphrase once. It's not too trouble but will
greatly improve security level.
4. You can hide the ESSID of this router by set 'Broadcast ESSID'
option to 'Disable'. Your wireless router will not be found by other
people in proximity if they're just using the AP scanning function of
their wireless client, and this can reduce the chance of being intruded.
5. Use 'Access Control' function described in section 2-7-4, so those
people who are not in your list will not be able to connect to your
network.
