Is there a way to connect to a wifi network and get UMA working when that network requires you to enter a username/password via a browser first? I seem to run accross this all the time ...including my "guest" wifi network at work. I live near a university and they also have a guest wifi network that requires browser based authentication.

I've searched the forums and can't find a similar question. Maybe I don't know the right keywords to search.

I can make a successful connection to the access point and get an IP address. But the UMA part fails with an "ISP error".

Yes. After it connects successfully, use the "Hotspot Login" button. There's even a bookmark in the Browser for "WiFi Hotspot Login."

Well, I can now connect to our AP successfully and everything is fine except the UMA part. Are you sure UMA will work with this type of Access Point?

I found a link that said "Web Redirection" is not compatible with UMA. Can anybody confirm if UMA will work against an access point that requres authentication via a web browser?

I can authenticate using the method in the above post but only UMA doesn't work.

Yes, it does work on networks that require you to "accept" Terms of Service, even login with a password, etc. However, keep in mind that not all networks support UMA. There are lots of port settings, etc. that can block UMA functionality. TMobile/RIM don't claim that it works on every network.

well, crapola. I just walked over to a "web redirected" hotspot by the house and was able to get on with UMA just fine with your technique.

So the one place in the whole world I want it, at work, I can't get it. They just setup a guest wifi which works great for unsecured browsing ...but no UMA.

Thanks for your help.

Certain ports need to be opened for UMA. You might talk to the IT department and see if it's something they can do. Ports 500 and 4500, if I remember correctly, as well as IPSec need to be enabled. Look in Main Page - BlackBerryFAQ under the wifi section for what is required. Take it to your IT department and see what they can do for you.
