WTR54G Wireless/Wireless Woes

Question

I've been having problems with my WTR54G when I am connected wireless in a hotel. It's being used as a wireless client to the hotel network with two laptops connecting wirelessly through the WTR54G. Everything works great and seamlessly (both machines have access to the Internet) with one huge problematic exception ...
The two laptops cannot see or ping each other. No Firewall software is configured. One machine is MacBook and the other is a Windows XP machine. On a wired network, they can ping each other without any issue.
By symptoms, you would expect that AP Isolation is enabled, but it is not. It's clearly disabled.
I'd like to figure out a way to make this work. Is there something that I am missing?

Under the advance wireless settings,reduce the beacon interval to 50,reduce the RTS and Fragmentation by 40 each and check if this works for you.
No effect, but I did experiment by switching the Internet connection to a wired type. Both wireless laptops can now see each other as a result. Unfortunately, I now have no Internet access when I use this mode.
I fear that the AP Isolation when using the wireless Internet may be an undocumented "feature". A few other clues such as the inability to change the wireless channel of the WTR54G, when operating with a wireless Internet connection, seem to suggest some real limitations of this device. AP Isolation may come along for the ride as that's the only way they can get it to work with a single radio.
Are my observations correct? Is this something that is simply unsupported?
Does anyone have a workaround?
