Thanks very much! Somehow I didn't get anything with tcpdump at first but eventually made it. I see: authorization request authorization response association request association response then a few data packets from the Samsung phone but nothing from DHCP and eventually: disassociation deauthentication. So I guess that my problem is DHCP and not the wireless connection per se. At least I don't really have to see what's going on between antenna and antenna. Phew, 18000$ saved ;-) I just wonder why it works with my MACbook. The latter sends a lot of "no-data" packets which the Samsung phone does not. Does the athn driver or hardware "think" that the phone is "sleeping" and times out? Unfortunately I can send wireless cards to you but I'm unable to send what you need most - time. Thank you for your good work. Eike -- Eike Lantzsch ZP6CGE
