One user has had trouble connecting to Cisco AP's with hidden ESSIDs. Before this, I had not gotten any report of success in associating with a hidden ESSID and thought the problem was general. Perhaps that is not the case. In the dumpfile that you sent me, the Netgear AP is broadcasting a NULL ESSID every 100 msec. This is obviously a different AP than the one discussed above. With regard to getting a DHCP address, there should not be any bcm43xx-specific problems, as long as reliable communications are established. There may be problems with certain AP's. For example, there was a recent "upgrade" to the firmware of Linksys WRT54G V5/6 units that killed DHCP connections to all Linux and OS X clients. It didn't matter whether the connection was wired or wireless. Only Windows clients worked, which gives you some idea of the depth of their testing! I filed a bug report and had to revert to the previous firmware version. It was fixed within a week, or so. To test the reliability of your connection, I suggest using the Iperf utility with some other host on your LAN as the server and your computer as the client. For bi-directional tests, use the 'iperf -c <server> -r' command. If the speed obtained by this test is 5 Mbs or higher, then your connection is reliable. If the above test works, I can suggest is that you post your AP make, model, and firmware level and ask if anyone else is using that unit.
