Being a social worker and rarely at home, I use wireless networks in coffee shops and bars a lot. In coffee shop A, where do a lot of work, I can configure my card with DHCP when booting to Windows, but under Linux (running dhclient) I get no DHCP offer from the server. In coffee shop B, everything works without a hitch under both Linux and Windows. I've been paging through my copies of Linux Unwired and Running Linux, but can't find much on DHCP. Any ideas?
