wireless Extensions version is incompatible with wireless-tools compiled in the kernel

[Fred Damberger]

Hi,
There is a version incompatibility between the Wireless-tools and 
Wireless Extensions packages compiled in the current  kernel of Ubuntu 
(7.10) (possibly this problem has been carried over to Hardy Herron 
(8.04)? It was there already in Feisty Fawn (7.04) but in Dapper Drake 
(6.10) the versions were compatible.

===
On my laptop I have Ubuntu 7.10 (kernel: 2.6.22-14-386) installed and 
get the following output from iwconfig:

 >iwconfig --version

iwconfig  Wireless-Tools version 29
         Compatible with Wireless Extension v11 to v21.

Kernel    Currently compiled with Wireless Extension v22.

ath0      Recommend Wireless Extension v13 or later,
         Currently compiled with Wireless Extension v22.

===

I.e. The kernel should have been compiled with version v21 of Wireless 
Extensions (not v22).

This prevents network manager from connecting to hidden access points 
and may cause other problems.

Since many institutional networks are hidden, for a lot of people this 
prevents the use of NetworkManager to connect to their network.

Thanks a lot!
