Hi Wolfgang, good to hear from you. I've followed your instructions with the latest version of compact-wireless tar ball i.e. 2011-08-06 and the current natty kernel (2.6.38) and so far it's working great. The ping results are the best I had so far with our tests, and it seems very consistent and stable so far. I'll try to work with it and update if anything goes wrong. Thanks for your help, If you need anything else feel free to contact me.
