WiFi Protocols Question:

basically there are many standards of wi-fi in the industry
but some popular of them are 802.11a, 802.11b and 802.11g/n
with the support of these wi-fi protocols we can
cummunicate/interact among the devices at the speed of 5Ghz
to 2.4 Ghz dual band cummunication.

if our wi-fi nic card so firstly we have to install their
drivers and after installation if we have wi-fi access
point then we can see the signal strength in the right
corner below just open that and find the access point to
connect,if A/P is configured with the security,type the key
to connect
