Hello since long time (always I guess) I have had problems when I tried to get an IP using DHCP from some APs.
At the beginning I thought that this was just an issue of one of my wireless routers (a Motorola WR850GP running dd-wrt), but recently I verified that I was unable to make the DHCP working with many free APs I tried (at the university, at the pub...). Practically, I associate with the AP (iwconfig confirms me it, but also the AP), but when I try to get an IP I simply don't get any dhcp-offer (or the phone doesn't grab it!), as you can see: r...@om-gta02:~# udhcpc eth0 udhcpc (v1.11.1) started Sending discover... Sending discover... Sending discover... Sending discover... Sending discover... [...] r...@om-gta02:~# dhclient eth0 Internet Systems Consortium DHCP Client V3.0.2 Copyright 2004 Internet Systems Consortium. All rights reserved.

So, the wireless association works well with any router. With some ones, unfortunately, I can't use the DHCP (also if, of course, the router supports it and I am able to get an IP using another device). I've tested this with Om2008, Debian, Android... Every distro has the same problem. I wanted to understand better this by running a packet sniffer while my notebook was in monitor-mode to understand what's happening, but I had no time (and who knows when I'll have :(). Werner, maybe have you done some research about this too? -- Treviño's World - Life and Linux http://www.3v1n0.net/
