Here are the few things I have discover about my P1.
I am using the old modem DV-230 which you have to face the modem to the base station to get good strength connection.
This also allows me to choose the base station I want to connect to by turning the modem's facing direction.

In my area there are 3 base station:
- 00:00:12:a0:10:32 - Fair download speed
- 00:00:12:a0:10:31 - Good download speed
- 00:00:12:a0:10:33 - Slow download speed

It doesn't really matter what the signal strength is, at least you should have orange bar, then face your modem to the base station with good speed and you will get good speed.
Chances are that good speed base station has less users.

Another things is that the direction changes at times (I have no idea why), and I have to turn the modem to find that particular base station again.
Its a pain sometimes, but once I got the 00:00:12:a0:10:31 base station it will get good speed.
