I am not sure if you have read the past messages on this.
Driver loads and the card associates with AP when WEP is not
used. However, no traffic is possible. That is the status when I last
tested (couple of weeks ago). Since then many changes have been made
to the code. Although I suspect any of those changes have an impact on
RTL8180, it may be worth to try.
You are also urged to debug/change to get this chipset to work. There
are plenty of users with this chipset, so many would benefit from it.
You need to compile the driver with DBG_REALTEK=1 with 2.4 kernels.
