Linksys WAP54G IPX WPA - TKIP - AES

Setup:
Novell Server 3.12/3.20 with IPX/SPX frame 802.3 and TCP/IP
Clients use Novell Client 4.90 sp2
Access Point Linksys WAP54G, newest firmware
Notebook Asus N3251NBH with windows xp pro sp1
Notebook wlan card Intel proset wireless newest software drivers.
Network camera Axis 206W

Everything works fine with TCP/IP

Our wlan network uses encryption WPA with AES algorithm,
because we have found out, that WPA - AES is the only setup to allow Novell Client
to access the Novell server via IPX/SPX. WPA - TKIP does not work with the Novell Client.

Why do we need the WPA - TKIP configuration?
The Axis camera does not support WPA - AES, it works with WPA TKIP only.

I would like to change the encryption to TKIP to integrate the camera into our network,
but the Novell Client does not like the TKIP encryption.

How can I get the Novell client to run with TKIP?

Thanks for any hints on this, best regards
