Now my Bluetooth tethering had degraded and it refused to connect to network. It seem at first when Xubuntu works great and connects quickly. After subsequently use, it degrades. I couldn't figure out what's wrong.
I did try tethering again on Ubuntu. It refuse to cooperate with me. I was thinking that USB bluetooth dongle is the culprit. I did see the dongle's LED stayed on and won't blink. I unplug and plug back in and it blinks but until I paired my bb to bluetooth and it got screwed when I tried to run dialup. It did 'connect-- success' then bam my BB Curve rebooted itself. After bb rebooted, I tried paired it and it failed to pair. I unplug and plug Bluetooth and LED flashes as usual and when I pair it again, it got paired but dropped out. Then bluetooth led stay lit. It seem that Bluetooth dongle is really crappy.
So I decide to order a new USB Bluetooth dongle (Cirago Micro USB 2.0 Bluetooth that is tiny enuf to plug into USB and forget it) and see if the problem solves.
I'll let u know how it goes when I got new one.
