working with CT5508

[Debudas123]

Dear,

i have 12 caps(3602) and one 5508 controller, i have configure all the things, but when i have enable the hight-thoughput (n mode), then no win7 laptops are connecting, but when i will disable it then it is connected with 54 mbps, so what will be the issue.

thanks

I have a feeling your PC's wireless card does not support 802.11n.  I believe it will only support 802.11 b/g and could be falsely advertised as "802.11 b/g/n ready".

this problem is in only win7 laptop, winxp are working fine

thanks

Can you specify the model of the wireless NIC driver and the version of the drivers?

This sounds like drivers as well.  Are the Windows 7 clients the same hardware?

Have you tried upgrading the drivers of the Windows 7 wireless NIC?

What happens if you use OPEN authentication, can the Windows 7 client associate?

Gee whiz.  Your drivers are woefully OUTDATED. 

Go here:  http://www.atheros.cz/atheros-wireless-download.php?chipset=37&system=5

Update your drivers and try again.  Your description eliminates wireless issues and continuously points to the wireless card.

same issue after update......

Can you post a screen shot of where you are enabling this hight-thoughput (n mode)?

Thanks,

Describe to me the Windows 7 you are currently using.  I mean how was the OS installed?  Is this OS stright from the MS CD/DVD or is the OS an SOE package?

The fact that WinXP and Win8 works fine but not Win7 means this TOTALLY ELIMINATES your issue as a "wireless" problem.
