[quote=“Mr. Rice”]If you want to secure your access point, you should use WPA encryption with a secure passphrase (more than at least 8 characters; containing no words from any dictionary; containing upper, lower case, numbers and special chars)
WEP encryption is weak and the passphrase can be can be decrypted with a small amount of sniffed traffic. This does not need any knowledge. There are tools for this, that do it automatically.
Restricting your AP to special MAC addresses is not effective either. With the right tools, an attacker can easily sniff your wireless traffic and then adjust his MAC address to one he picked up, and connect to your AP…
Check all your devices, whether they support WPA encryption… If they do, I would suggest setting it up…
I agree with Mr.Rice. Go with WPA instead of WEP, which is very outdated and easily beaten these days. It is also easy to spoof a mac address, but by all means keep using it as well as WPA. Won’t do any harm.
Also, try to have a fairly hard-to-guess admin password on your router.
