I'm currently running OS2007HE on my 770. This problem existed with the latest 2006 OS as well.

I can log into any open "home network" without any problem. I get a log on screen at Starbucks for T-Mobile, and can communicate short of Paying to Log in.

Boingo is no problem at Balt-Wash Int airport.

However I wasn't able to get on line at Comfort inns, or Jet Blue's WiFi hotspot at JFK.

The tablet connects with the network at both locations, but when I try to access a URL, it comes back with a network problem. When I look at the connections, it shows up as being in ad-hoc mode. I've changed this to Infrastructure, but that doesn't seem to help. Every once in a while, something clicks and I can get into tableteer. But that's about it.

What am I doing wrong? Is there a setting I'm missing?

Thanks.

Comfort Inn's wi-fi network has "issues" to say the least.
On a recent cross-country trip I found that most (all?) of them only allowed for one "PC" per room to be connected to their wi-fi network, easily gotten around by entering different rooms numbers for the username since they use the exact same password for every room account (silly, silly, silly...).
On a recent stay in Pigeon Forge, TN I found my Macbook Pro refused to connect at all to anything in the area while my N800 found - and connected to - wi-fi networks all over the place. Strange.
I'm thinking you're in "crowded" areas and the hotspots are probably at their peak load and that's why you can't get an IP. If an access point's DHCP server has a long lease time and is prone to periods of heavy use from drifters then it might have served out all the IP addresses it's allowed to use. Usually a router reboot will solve that problem, but not always. I've seen some routers in public hotspots have a lease time of "indefinite" which ALWAYS winds up locking up the router over time requiring a reboot.
I usually just hack my way into the AP/router and "fix" it for them.
You have to remember that the lowest-common-denominator in the IT world (read: sub-contractors) probably set these things up and probably the only configuration they did was to change the default login/password to the admin interface, if that.

Thanks for the reply. In the case of comfort Inn, I had a laptop with WiFi sitting next to the 770. I had no problem logging in. The 770 couldn't even get to the sign-in screen whether the laptop was on or off.

JetBlue's Wlan is wide open with a lot of capacity, so I don't think that's the problem there.

Maybe Jetblue has it running on N-only mode or something?
Or perhaps it's setup for MAC-address only? I don't know anything about Jetblue other than it's an airline.
And since they aren't paying me for a survey...
