Blackberry - WiFi connection error W004

Hi,

I have some problems with WiFi rather unusual on my house network with each blackberry device that tries to connect. My network hardware configuration is rather unique, I have therefore not been very fortunate search online for the possible solutions.

Connection Pref: Wifi Preferred
UMA wifi available: (checked)
Connection: (x)
Error Code: W004
Status: ISP error. DNS server cannot be reached

I have tried a battery pull, actually several, I have tried removing the WiFi profile and all other things that I can think...

Help!

Re: Blackberry - WiFi connection error W004

This seems to be a failure of the IP stack on the BlackBerry or the ARP->IP translation, because it is not even capable of ping itself on the network. Have you tried another browser as Opera Mini or bolt? I have had this problem with the w004 errors and it was a dns question. I have indicated to another dns server and then my isp uses, and he began to work fine instantly. You need just change your DNS.

Try to download the 3rd part browser to your office and the use DM Add/Remove app to install the browser. After the browser is installed open its options and enable WIFI. Make sure that you have data lit manage network connections. I have my setup my Blackberry without the data plan and it has no problems with connection to any router.

WiFi connection error W004 means DNS server cannot be reached

1. Retry connecting to the network.

2. Reboot the wireless router.
