Is it possible to use the N810 to tether a laptop to the internet? For some weird reason, I can't get my laptop to connect to the wifi yet my N810 connects just fine. Is it possible to use the N810's bluetooth to tether to the laptop to get internet onto the laptop?

In theory - yes. But I suppose it will be a very complex solution. Try to find in Internet some advice how to connect the tablet to Internet using bluetooth and then apply the method in the opposite direction.

Notice that due to hardware limitations the tablet can not transmit simultaneously bluetooth and wifi packets. This will limit the speed of the connection.

I think you are chasing the wrong end of the problem. You'd be far better off and more likely to succeed trying to solve the laptop to internet direct problem.
