Notes: - IP Address of Both Wire less Routers/ APs must be in the same address class. - If WDS is configured be tween two wireless routers, then both might have to be different SSIDs , otherwise they might not work. (this point needs to be confirm more from other resources too). - for same SSID (called roaming) , there should be a combination of one wireless router and one Access point.   Primary - Wireless LAN Router/AP configuration Secondary - Wireless LAN Router/AP configuration - which needs to be WDS bridged with the Primary Wireless Router/AP. 

************** For Windows: ************** netsh wlan show networks mode=ssid and netsh wlan show networks mode=bssid ************* For Linux: ************* To display WiFi signal strength in the terminal, you can run this command: watch -n 1 "awk 'NR==3 {print \"WiFi Signal Strength = \" \$3 \"00 \"}''' /proc/net/wireless" watch -n 1 cat /proc/net/wireless iwconfig "Interface-Name-Here"          example:         iwconfig wlan0         or         iwconfig wlan1         or         watch -n 1 iwconfig wlan1    [for continuos observation of the link] Wifi Signal Strength(Link Quality) in Percentage: while [ 1 ];do clear;echo "WiFi Signal Strength (Link Quality)";a=$(/sbin/iwconfig wlan1 | grep "Link Quality" | awk '{print $2}' ...

Quick way to hack SSL password Requirements: 1. One Laptop Install BT-5 2.Working Wireless Lan Card and connected to any hotspot 3. SSLStrip installted 4. Etthercap installed 5.urlsniffer installed 6. aprspoof installed 7. Basic knowledge of linux and network Note: If you will try it using BackTrack-5 all will come pre-installed Be aware —you can only sniff email addresses and passwords on the same LAN, which means not on a remote computer outside the network. Step 1: In the first step we have to make sure that we are connected to a Wifi network and scan the available online node by using any network scanning software Step 2: One we know find the victim run this command and keep it running on the shell.

Q. How many clients can associate to the AP? A. The AP has the physical capacity to handle 2048 MAC addresses, but, because the AP is a shared medium and acts as a wireless hub, the performance of each user decreases as the number of users increases on an individual AP. Ideally, not more than 24 clients can associate with the AP because the throughput of the AP is reduced with each client that associates to the AP. Q. How many service set identifiers (SSIDs) can you have per VLAN? A. You can have only one SSID per VLAN. The use of multiple SSIDs over a single VLAN is not supported with Aironet APs. Q. How many wireless IP telephony handsets are recommended per AP? A. IP telephony network sizing is essential to ensure that adequate bandwidth and resources are available to carry mission-critical voice traffic. In addition to the usual IP telephony design guidelines for sizing components, such as PSTN gateway ports, transcoders, WAN bandwidth, and so forth, also ...
