While I can send UDP frames just fine from the AP to the client the only a few broadcast frames reach my client. What is really puzzling is that on the client machine using tcpdump I can see all the broadcast frames arriving, my application sees only a small fraction of them. * I have suspected some bug in the application, but the same app using the same computers works fine when using wired ethernet. * I have used both 2.6.30 and the latest wireless-testing kernels, the results are the same * I have used the latest hostapd in AP mode * I did the same tests in ad-hoc mode, the results are the same * I used both atheros and intel wireless cards, the problem is not related to the wireless drivers. Any ideea what I'm doing wrong? Thanks, Valentin
