How to Secure Wireless Help

Mostly WLAN hardware has gotten easy to set up and many users simply plug it in and start using the network without giving much thought to security.here we tell you about how to configure the security features of our wireless router or access point. Here are some of the things so that we can protect our wireless network;
1) How can we Secure our wireless router or access point Through administration interface ,
Mostley we have seen all of the routers and access points have an own administrator password that's needed to log into the device and modify any configuration settings. some of devices use a weak default password like the manufacturer's name, and some don't have a default password at all. we have to set a new WLAN router or access point,firstly we will have to change the default password to something els and we may not use this password very often, the only one way to access the router or access point we may be to reset it to factory default settings which will wipe away any configuration changes we have made.
2) We Don't have to broadcast our SSID.
Mostly WLAN access points and routers automatically broadcast the network's name, or SSID. This will make setting up wireless clients extremely convenient.after that it will make our WLAN visible to any wireless systems within range of it.
3)We will have to enable WPA encryption instead of WEP.
802.11's WEP (Wired Equivalency Privacy) encryption has well-known weaknesses that make it relatively easy for a determined user with the right equipment to crack the encryption and access the wireless network. A better way to protect our WLAN is with WPA (Wi-Fi Protected Access). We all know that WPA provides much better protection and is also easier to use.
4) And Rememberone thing that WEP is better than nothing .
If we find that some of our wireless devices only support WEP encryption , We will have to avoid the temptation to skip encryption entirely because in spite of It's flaws,when we will use WEP is still far superior to having no encryption at all. Ifwe willuse WEP, we don't have to use an encryption key that's easy to guess like a string of the same or consecutive numbers also,and we have to see this page need help getting WEp to work.
5) We have to Use MAC filtering for access control,
Use Unlike IP addresses, MAC addresses are unique to specific network adapters, so by turning on MAC filtering wecan limit network access to only our systems . when we will use MAC filteringwe need to find the 12-character MAC address of every system that we will connect to the network, especially if we have a lot of wireless clients or if our clients change a lot.MAC addresses can be "spoofed" (imitated) by a knowledgable person, so while it's not a guarantee of security, it does add another hurdle for potential intruders to jump.
6) We will have to Disable remote administration,
We have seen that Most WLAN routers have the ability to be remotely administered via the Internet. Ideally,we should use this feature only if it lets us define a specific IP address or limited range of addresses that will be able to access the router. Otherwise anyone anywhere could potentially find and access our router. it's best to keep remote
