Can't connect at public WEP Access Point, Can connect at home.

Hi,
My problem is that at home I can connect wirelessly to my router using 192.168.11.1 as the gateway. When I take my laptop out to my local coffee shop however I can't. the gateway is 192.168.1.254 I've tried using networkmanager & wicd. It connects perfectly and gets an IP address but won't connect to the Internet. I tried pinging the gateway & google but neither gets a response. For google it says "unknown host." For the gateway it says "Destination unreachable." On Windows 7 home (same laptop) it connects perfectly. I've tried looking at rc.conf and resolv.conf but they both look normal and both work on my home network.

Using wicd in errors.log there is the line "dhcpcd not running." I tried manually running ¨/etc/rc.d/dhcp4 start¨ but that gives me the following.:

No subnet declaration for wlan0 (192.168.1.176).
Feb 11 11:47:19 localhost dhcpd: ** Ignoring requests on wlan0. If this is not what
Feb 11 11:47:19 localhost dhcpd: you want, please write a subnet declaration

Feb 11 11:47:19 localhost dhcpd:
Feb 11 11:47:19 localhost dhcpd: exiting.

On my home network it sees the router and connects to the Internet fine. I'm at my wits end as far as what to try to make it connect on the public network.
Thanks in advance for any help!

... But that is a dhcp server, not a client. In other words, you are trying to tell your computer to provide other computers on that public network with IP addresses. Because you did not set your configuration file up to serve that subnet, the server choose to ignore it. This is fortunate, because the owner of that network might not have appreciated that

You want to run dhcpcd, which is a client. You might also try dhclient, a client that sometimes is more forgiving.
