I'm another one with this issue.
Both PC and BB are connected just fine. Packets sent, but 0 received.
Tether version 1.4.4.0 on BB
Tether version 1.4.3.7 on PC
Reinstalling both Tether on PC and BB, checked.
Rebooting both PC and BB, checked.
Disabling all network adapters on PC, checked.
Tried on several PCs, checked.
Anything else I could try first before I ask for a refund?
Could you provide us with the exact wording for what Tether says on the PC?
When Tether is running on the BlackBerry can you press the BlackBerry key and select "View Log", could you provide us with the full text of the Tether log please?
It's very important that you write everything word-for-word from the questions above. If not we may end up going back in forth through emails longer then necessary.
