Followed the instructions on this site but am still having problems with my 5450-billionton USB Bluetooth dongle (sw ver. 1.4.7)- WinXP Home setup. Everything worked out fine until I did a restart on my desktop:
a) when my desktop restarted, ActiveSync would not run and a message would pop up: "TCP/IP protocol not installed";
b) if I go to my Ipaq's Bluetooth Manager and tap "Activesync via Bluetooth" it just says "connecting" but won't sync;
c) I connect to the internet using cable and have a dial up ISP as backup. When I click on Internet Explorer, it asks me if I want to use my dial up ISP to connect to the internet. If I click cancel, it won't connect to the internet. My connections are all messed up.
Uninstalled the bluetooth software and did a restart but got the same results as above. Good thing there's system restore so I was able to get things back to normal.
Been doing this whole thing for the past 3 days and no success even if I closed down the firewall and antivirus software. Any kind soul who can help me out?
