reduce the power from 100mW to 10mW to save battery power

By default the power TRANSMISSION is set to 100mW but can be dropped down to 10mW to conserve power. I personally drop mine down to 10mW since I am really not too far from my router and it really saves on the power usage.

You can find it here:

Control Panel -> Connectivity -> Connections -> (edit any existing connection) -> Next -> Next -> Advanced -> Other -> WLAN Tranmission Power

GPS Lock-on speed FAST - tips here

GPS Lock-on speed FAST - tips here

---

I have had my N810 for a few days now. Initially, I was very disappointed about the GPS, very slow locating satellites and locking onto them. But I have changed my mind now.

The problem is the location of the antenna on our N810. It's on the top edge of the N810 next to min/max windows buttons. When I hold my N810 vertically, so the zoom buttons facing the sky, I can have my N810 lock-on to the satellites in less than 15 seconds (clear sky), that's about the same as my Garmin GPS. Once the GPS has located the satellites, you can then turn the display to face you, so you can read the screen. The N810 seems to be able to maintain the satellites fairly well after the initial lock-on, even indoor.

The worst position for the GPS antenna is to place the N810 on the table with the LCD facing the sky. This way, it will take forever to locate the satellites.

The difference between the N810 and my Gamin Nuvi is that the Nuvi has a built-in swivelable antenna which help to locate the satellite in any position/angle.

why Nokia N810/N800 is not sold so good as Ipod touch?

I'm getting understand the reason.
The N810 is a product need you to setup, there are so many things need you to do once you open the box, though you can surf the internet or do something else without updating anything.
But if you want to personalize and get the most satisfied performance you have to DIY something and spend lots of time searching the internet to find answer. sometimes you just have to try it by your self. For me, like linux and not much experience on it except Ubuntu, I feel I got in to a dark tunnel when start to configure my N810. That's where the fun is and people who like it because the difficulty, so as people who hate it.
The ipod touch is a simple entertainment product and you can just use it. Not much things you need to do to set up. Just like a fool camera.
