Orinoco/Realtek 8180 interoperability problem

[grungie]

Hello,

I've been using two ELSA Airlancer cards under Linux for a few years 
and recently tried to add a node to my small Wi-Fi LAN. Both ELSA cards 
are running the orinoco driver, one under 2.4.x and the other under 
2.6.x. Everything is fine until I try adding the Realtek 8180 Windows 
XP machine to my Ad-Hoc network.

Just to make sure this is not a WEP problem, I have temporarily 
disabled encryption.
The funny thing is that Windows sees my WLAN, tells me it has excellent 
link quality but fails to talk to my Linux boxen (and vice versa). On 
the Windows side, I get loads of "TX Beacon Errors" and also quite a 
few "RX CRC Errors".

This is the output of iwconfig on the 2.4.x box:

eth1      IEEE 802.11-DS  ESSID:"ducon"  Nickname:"armada"
           Mode:Ad-Hoc  Frequency:2.457GHz  Cell: 02:02:2D:0F:87:A3
           Bit Rate:2Mb/s   Tx-Power=15 dBm   Sensitivity:1/3
           Retry limit:4   RTS thr:off   Fragment thr:off
           Encryption key:off
           Power Management:off
           Link Quality:0  Signal level:0  Noise level:0
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:1
           Tx excessive retries:11  Invalid misc:0   Missed beacon:0

Any idea what's going wrong?
