Understand the quoted range is a maximum, not average. You will almost always see lower numbers that the quoted range.
Range examples:
A general rule of thumb in home networking says that protocols 802.11b and 802.11g WAPs (wireless access points) and routers support a range of up to 150 feet (46 m) indoors and 300 feet (92 m) outdoors.
Another rule of thumb holds that the effective range of 802.11a is approximately one-third that of 802.11b/g.
Both of these rough estimates fall on the high end of what's seen in practice.Obstructions in the home such as brick walls and metal frames or siding can greatly reduce the range of a Wi-Fi LAN.
802.11a is most susceptible to obstructions. Interference from microwave ovens and other equipment also impact range. 802.11b and 802.11g are both susceptible to these. Of course, you can extend a Wi-Fi LAN's range by chaining together multiple wireless access points or routers. -

Invest in the latest standard for WIFI Wireless.
802.11N delivers 14x the speed of 802.11G & 6X the range of .11G.
In the real world this brings the numbers to very optimistic possibilities.
If a real world range for the old 802.11G yields 30feet through brick walls and floors, the user could see up to 180 foot range. (30x6=180) In the real world we should expect half and hope for more. (30x3=90) So this means a range of 100 feet through several walls and floors should be easily obtainable. This is why WIFI numbers are rarely bragged about. The range of success is all over the board and greatly relies on the placement of WIFI components. Without a doubt, the range of 802.11N, makes WIFI more practical than ever before. Even patio and outdoor use should be doable. -

Upgrade other equipment that can interfere with WIFI networks.
With the explosion of WIFI networks, other technologies are building products that won't interfere as much with your WIFI network. -

While setting up equipment, keep in mind, angle will increase perceived thickness of wall and floors.
* A 2 degree angle through a floor will make the floor appear to be 42 feet thick.
* You can add extenders to the wireless network. This increases signal strength and range. -

* Placement is critical to success when it comes to wireless networks. You will want to keep all networked devices away from power cables, 2.4ghz wireless phones and microwaves. You would be wise to consider upgrading wireless phones to the new DECT Technology to avoid interference.
* Keep your WIFI products away (at least 3-6 feet) from electrical devices that generate RF noise, like microwaves, Monitors, electric motors, and UPS units.
* In a very large house or building, the installer can add a wired connection between 2 or more wireless hubs (or access points). One upstairs one downstairs. This process creates a much wider range of access points still all being wireless to the end user. Now a laptop can roam through 3 levels of a house and as one signal fades the connection will pick up on the next access point that is hard-wired to the primary router.
