Hi,

There are few things we can say

(a) It does support 2.4GHz only therefore it CAN'T "see" SSID's which use 5.0GHz

(b) SSID's can be hidden (no broadcast) therefore it can't see,

(c) This is a slow card but a right driver may help.

Machine came with FreeDOS. Please try wireless driver for Windows 7:

Hi as you said it is unable to scan SSIDS of 2.4GHZ  but my friend using dell laptop with 2.4GHZ wifi adapter he is seeing all SSIDS and able to access all WIFI routers there is no issue with them. But only HP laptops have this issue 

Here advanced properties of HP and DELl laptop are also different 

Kindly help me to solve this issue

Thanks and regards

Is your laptop connecting to other wireless routers or accesspoint.  If so there there is an issue in the channel selection in the routers.  Pls make the channel selection as manual and for 2.4 GHZ choose the channel 6 and for 5 GHZ choose the channels above 31 or so.  I had this same problem.  But when i did this manual channel selection in the router it worked well.  Thanks to the ACT broadbad network service provider who provided this tip
