Multi-WLAN: Clients don't find AP, can't call 7920

[markus.rueger]

Hi!

We use some Aironet 1200 AP's with a dot1q-trunk and four SSID's. The first ist our guest-vlan with enabled beacons. The second and third is four a different company in our buliding (we provide LAN service for them). The fourth is for mobile voice-over-ip (with

Cisco IP-Telephony).

We have now two problems with this scenario:

- The PCI-Wireless-Cards of our customer don't find

the AP (only the beacon-net). But we configured

the network manually with ssid and wep-key in

WinXP and Win2k (D-Link and Netgear-Cards).

With my notebook and Orinocco-Card it works fine.

- The IP Phone 7920 registered at CM (manually

configured SSID and WEP) and I can call-out. But

call-in to the phone work only somethimes. Mostly

I can't call this phone. I get a call tone one or

two times and then a busy. The 7920 doesn't ring

and afterwards it search for an AP and does a new

registration there. Off course before I called the

phone it was already registered.

Do you have a solution for this problems?

regards Markus

I can only maybe help you with the first problem: maybe the client cards does support only broadcast ssid and it doesnt matter if you enter the ssid in the OS. that could be the problem i had the same issues with Linksys usb clients.

the second problem: i cant help you we also use the 7920 within vlans and it workes fine.

regards Bernhard

Thank you for your answer. Ok, I will check this with these adapters.

Now the voice-problem. We use CM 3.3 and 7920 firmware 1.0. Here is my AP-Configuration. Mybe it would help someone. IOS-Version is unknown because I am currently out of office.

regards Markus
