Hello, I am a brand new convert over to BB's and just purchased an 8820 and have been reading through threads for the last 2 days and have not been able to resolve my issue.

First, let me tell you that I have upgraded to the latest 8820 software (4.2.2.338), I have gone into the "Advanced Options" and changed the "Default Browser Configuration" to "Wifi Browser", I have opened the browser that comes with the BB and gone into the options and changed the "Browser Configuration" to "Wifi Browser", I have also downloaded Opera and changed the same settings.

I have configured my BB to connect to my home network and everything is working correctly, when I go into the "Manage Connections" area, both the "Mobile Network" and "Wi-Fi" connections have a green check mark next to them. When I use the browser or Opera, or connect with Facebook, and use the EDGE network, everything works great...But when I turn off the "Mobile Network" in the "Manage Connections" area and attempt to use the BB browser it tells me that "The radio on the device is currently turned off or the battery is too low for the radio to be used. As a result the browser cannot retrieve any web pages." But this shouldnt be the case because the Wi-Fi connection is still running and has the green checkmark. I get different errors when trying to use Opera or Facebook, but needless to say they wont connect.

Any ideas that the community would be much appreciated!!

Welcome to the forum!

Did you resend your service books after upgrading the OS?

I hadnt, but I just went into "Options" then "Advanced Options" then "Routing Table" and hit the menu button and did "Register Now" and received a text message that my BB had been registered with the network.

I then turned off the wireless connection again and attempted to startup the browser and had the same problem as above. I checked the settings and everything is set to "Wi-Fi Browser".

In Menu/Options/Security Options/Firewall check that BB Iternet Service is not checked to be blocked.

The "Firewall" has a setting of "Disabled" and nothing is checked at this point.

When you turn off the Mobile network, do you have UMA appearing on your screen?

No...in blue on the line underneath the battery icon it has the name of my home wireless network that it is connected too and on the top line to the right of the date it has "WiFi" in bold black/white. There is nothing that says UMA, but from what I have read AT&T does not support UMA, they will only allow you to use Wi-Fi for data, not for voice....UMA is strictly a T-Mobile thing.

Can you go to Menu/OptionsWiFI Options/ select your connection (home wireless network)/BB buttonm/Wi-Fi Diagnostics

and see what the feedback is on UMA

There is actually no UMA listing under the "Wi-Fi Diagnostics" menu...there are 3 headings in this menu "Wi-Fi", "VPN" and "Blackberry Infrastructure" and the green checkmarks seem to be in the right place in the "Wi-Fi" and "Blackberry Infrastructure" areas.

Under wiFi you should have Status: Network acquired witg your local IP address and connection data rate...
Under UMA, you should read: Coonect Pref.: Wi-Fi Preferred and UMA WI-Fi Available and connection checked in green.
If not, it might be a router issue. I would check that the device is properly authorized in your wireless network. (on my netgear, I have access control set so that only devices that are authorized can access the network)...

OK...I still dont see UMA, but it reads the following under "Wi-Fi"
- "Association" has a green checkmark
- "Authentication" has a green checkmark
- I have a valid IP address off of my router
- "Connection data rate" of 54 Mbps
- "Status" of "Network Acquired"
- "DHCP" has a green checkmark

On my netgear, I do broadcast my SSID, but protect by limiting which MAC addresses are allowed to connect, so I had already pulled the MAC from the BB and put that into my wireless router's MAC address table.

Try a battery pull.

Then in the browser in Go To: type an address (e.g. google.com) and see what happens.

Alright...I believe I have figured out the issue.

I purchased the phone on eBay, it was supposed to be brand new, but I believe it had some kind of policy already loaded that restricted it from routing through the wifi connection.

When initially trying to use the wifi connection, I had yet to connect to my company's email system and had a personal BB plan through AT&T. In talking to AT&T on the phone I got the plan switched to an "Enterprise" BB plan and was able to connect my phone to my company's email system. When that happened a new policy was pushed down to my phone. After pulling the battery and re-booting I was then able to disconnect the wireless connection and only use the wi-fi connnection.

The caveat being that the "browser" that comes pre-loaded on the BB still will not use the wi-fi connection, but all other internet apps. will, such as google talk, facebook and opera mini. I have played with the settings and cannot get the browser to work, but am comfortable with the setup I have now.

Thanks for everyone's help.

On a good 8820 which was not messed with browser should work over WiFi. In fact, it seamlessly switches between WiFi and EDGE with the preference given to WiFi.
That's the idea, is not it?

Also, 8820 does not have UMA. If properly connected to WiFi and RIM, it will show WiFi in bright black and white colors.
