6. few questions and notes

Does your router have external antenna(s)?
If you can, keep the box as far away from walls and floors as possible. Keep it away from metal objects like filing cabinets. Keep it away from electrical devices especially fluorescent lights.

You want your signal to be as close as perpendicular to walls and obstructions as possible. Putting a access point next to a wall and being on the other side at a sharp angle will make the wall look like it is 10-feet thick (signal will on the hypotenuse rather than a right angle).

Most routers offer the ability to bump up the signal strength of the transmitter in the configuration.

Get a took like MetaGeek's inSSIDer (http://www.metageek.net/products/inssider/) and configure your channel to be centered on the most open channel in respect to your neighbors.

Since your other workstations are wired, consider moving the router or at least purchasing an external antenna and cable to move the signaling to an area where it will be most commonly used.

Buy another access point and have one for each of the floors (make sure both are not set up to be DHCP servers or you will have address conflicts).
