Sounds like a hardware problem

First > try changing the modem port (default is com3, try changing it to com4 or com5 whichever is free)

Try querying the modem again

Second > Contact your modem manufacturer

80710723 Possible Port Error - Try opening ports , TCP port: 80, 443, 5223 and UDP port: 3478, 3479, 3658. or add Ps3 to DMZ

You really might want to try creating the connections again on your PS3 system on the same modem/router you are using.

Just re-configure you connection settings and see if that helps.

Hi,

BlackBerry 8350i does not support "Phone as Modem" straight out of the box :(

Your best solution would be to try Shark Modem. It's a BlackBerry application that allows you to use your BlackBerry modem. 8350i BlackBerry Modem Application

Confirmed that the 8350i doesn't support modem > here

Internet connection through Internal modem in Laptop

Two solutions:
First for the more experienced:
find the modem on the underside of the laptop unscrew/ re-seat the modem, test, if it works great, if it doesn't try inserting foam, or paper between the modem and the "black case"... if you cant find the modem locate the manual for the laptop.

second (and possiblely the best) 
Disable the onboard modem and replace it with a USB one

Modem in use

Try the following:

-Open the Control Panel
-Open System
-Click on Device Manager
-Click on Modems
-Highlight and right click on the listed modem
-Select Uninstall

Close out anything open and Restart.

IF (!) Windows is cooperating, it should 'find a new device' and reinstall the Winmodem (it's only software and a little telephone line matching).

If Windows fails to recognize the 'new device,' you will have to manually reinstall it via the 'add new hardware' path in the Control Panel.

As with any Windows stuff - rotsa ruck!
