I have setup the WIFI in my 8820, and it already connected to the router.
but when I open the browser, it cannot visit any website.
how to go online by WIFI ?

I read something about the 8820 (at least with AT&T) that you will need a BlackBerry data plan in order to use WiFi. The following comes from Engadget Mobile:

Sources are telling us that RIM's upgraded 8800, the 8820, will finally be ready for AT&T come the 15th of September. As a refresher, the 8820 adds WiFi to the 8800's buttoned down, all-business spec sheet, but it turns out there's a very sneaky catch: WiFi won't be usable unless the subscriber hooks up a data plan. We're guessing this'll be hacked in all of about 15 minutes, but yeah, buyer beware. AT&T will be touting the 8820 as rocking twice the battery life of Verizon's 8830, so at least you'll be able to curse the data lockdown for twice as long before you run out of juice.

So I don't know if there is something special that needs to be done with it first.

so strange. WIFI is local network..how does the carrier control it?

By locking out the use of WiFi on the device without a BB Plan. It is quite possible and could be easy or very hard to work around for those who want to use the WiFi but have no plan

I used WIFI to go online sucessfully last night.
no need any carrier data plan.

Just set the WIFI connection to your own router and change the browser setting to [WIFI browser], then choose the WIFI login in in the browser.

I am using the CSL HK version . I am not sure this way can be worked on other carrier's version. anyway you can try that.

I think there's wrong with my setting. coz my 8820 opened the website with a very very slow speed, sometimes it also showed " cannot find the server" ,then couldn't open the website.

one more thing, I also cannot login the MSN by WIFI. Does it need any other special setting?















VPN status: disabled

as per the blackberry manual, the WIFI icon should be black when connects to WIFI sucessfully,
I don't why the WIFI icon is always gray.......

Most likely because you have no data plan with your carrier. The carriers are not going to put out a product that enables the users to get the features without paying the money.

ok. If I joined a data plan for one month, then I cut off it, can I still use the WIFI function?
In addition, Is there any new ROM can be updated to unlock the WIFI?

Let me answer with a quick scenario. I have a TMo Pearl with BB data plan (browser, push email, etc.) My wife has one on another carrier (Unicel) with no data plan. If I put my sim card into her BB then all the service books are pushed to the device including browser, etc. However, when I remove that sim and put the Unicel sim back in the service books for the browser, etc., disappear.

The moral of the story is when you cancel your data plan you will no longer be able to use the wifi.

At this point, it is my understanding that you MUST have a BB data plan in order to use the wifi on the wifi enabled BB's. I don't personally have one but that is what I've read in all the documentation out there.

tks John, I got it.
is it also impossible to use my own wireless router at home even if I join a data plan? coz there is no carrier's hotspot at my house.

Hoping there will be a new ROM can solve this problem.

With a BB data plan you should be able to use your home router, assuming you have all the wep keys, etc.

thanks for your quick replying
I understood completely. that's a bad news.

ironicly tmo hotspots are NOT WEP encryped however the DO an a pormtp tha kicks you to the page to authenticate your hotspot account.
