Wireless: why is Starbucks different from Panera?


Dumb question maybe, but...

I've got a recent D-Link wireless card that works great in some places. But at others, either 'dhclient' or 'dhcpcd' can send out a DHCP_REQUEST message until it's blue in the face and it will get no reply. Literally no answer.

I can do 'wlanconfig list scan' and see the Panera server and my wife is using the very same card (on a Macintosh) and is connecting just fine. And, like I said, I have zero difficulty in some places (like this one, for instance).

I tried 'ip route add -host 255.255.255.255 ath0' which works on some places. Nada.

So... what are the sort of things I might be overlooking?

We've got a coffee shop that you have to go ask them for an IP address. They shut off dhcp, but the gateway is posted behind the counter. Basically when I go there, I just pick a random number between 2-254

Router = 192.168.1.1
Broadcast = 192.168.1.255

They'll look at the list of leased and tell you the next number, or if you know what your doing, pick a number & go for it.

Sorry if this doesn't help much.

Nope, they are definitely running a DHCP server.

My guess is that the signal just isn't "getting out." But I don't know why not, because identical hardware on another type of box works flawlessly. Also, a "wlanconfig .. list scan" clearly shows the channel I'm trying to connect to. It's open, etc etc.

I was wondering if maybe it has something to do with 802.11g. Or something along those lines. I just can't fathom why I could see that the network is out there (ESSID correct, channel correct, no WEP), and not get it to answer.

On one system I knew that there used to be a problem that could be solved with:
route add -host 255.255.255.255(etc...)
but no joy.
