Hello - been lurking since I bought my Droid and have learned a lot from the forums. I have an issue that I haven't seen discussed anywhere, but if someone's aware of a thread, I'd appreciate a pointer to it. My Droid connects to my wireless network just fine (Apple Airport Extreme N extended) and for a time, I will have no problems. Then, and I can't figure out a specific behavior, my entire network will go down. I have to reboot my router to get things up and running again. This even affects things that are hard-wired to the router not just wireless clients. I thought that the AP was assigning the same IP to two clients, but the logs say no. I know that it could be coincidence, but I have had zero problems before connecting my Droid to the network, and have zero problems when I leave WiFi off on my Droid for days at a time. Best guess: something having to do with the WiFi connection when the Droid goes to sleep. As bizarre as it seems, I really do think that it's something to do with the phone. Any ideas? Thanks in advance, Dave *** UPDATE *** Turning on network robustness appears to have solved the problem. Network hasn't dropped yet. I will continue to monitor it and will repost if I have anything new. Thanks to Barbara and Aaron for their prompt replies.
