Certain machines cannot see broadcasted SSID

Colin Higgins

I created a guest wireless network on my 5508 controller (uses default a/n), and it is set to broadcast the SSID

 

Almost everyone can see this network SSID: my Mac sees it right away, and I can join it and surf the web all day.

 

Two Windows laptops had an issue seeing the SSID --it wouldn't show up when they scanned for wireless networks. One of these was corrected when the machine was updated to Windows 8.1

 

The other is a HP laptop running Windows 7. Even though we did some updates, the machine can't see the SSID. Even if I pace the machine within 10 feet of the AP, nothing. The user's Android phone sees the SSID no problem.

 

Since this client is never joining the network, I have little to go by (no logs).

 

Has anyone seen this? What could be the issue?

Please try to re-image the laptop and check it again if it works.

Sounds like your device has a b/g/n radio --- no a/n.  You will need to enable the SSID on the 2.4Ghz radio.

I hope this helps.

Please reimage the laptop. your problem will resolve.

we are in the process of doing that--I will let you know if it works

You can also try making sure you are using channel 149-161 or 36-48. (I believe you said you are using the a/n band (5GHz)). Some devices may not work on all channels, it's rare but happens (even my smart phone had that problem with my home router).

HI colin,

1. Did you enabled all radios ?

2. Did the client(windws lapi) support 802.11a and 802.11b radio(2.4/ 5 Ghz).

3. If above both points are ok then check the driver of the machine and try to update.

 

also paste the sh wlan out put here.

Check these and let us know the outcome.

 

Regards
