Re: OT: Wireless Signal Strength

Salam Saeed,

I checked your idea. I used one D-link wireless router for Wi-Fi
connectivity on the same machine where signal strength problem was
encountered, but it is working fine. even on greater distance.

The thing with WLC managed AP which is very surprising is that the users
even sitting very close to the APs are encountring this problem. There are
two WLCs, each has 12 APs connected. This problem is particular in areas of
floor were are only two APs on the whole floor. By the way those APs are not
properly placed so i will try changing the position to see if convergance
for wireless network improves.

Regards,
Khurram
