ashokvikas :
My laptop was unable to detect particular WIFI networks, but it is detecting some other networks.DELL Inspiron 1545 is my laptop model.Plz give me the solution.
for that may be many reasons
1. wifi you don't see may be hidden (SSID).
2. Signal should be weak enough that your laptop isn't able to get.
3. Router's wifi mode may be at high performance instead of compatibility.
