I have a buffalo air station wireless router. my signal at my bedromm about 40 feet away is hit and miss. i have an extra smc wireless and a us robotics wireless router laying around. can i use these as a repeater to extend signal?

If the router has "N" value it should run a good distance away, even to the neighbors home. If "G" 30 Feet to 50 feet max.
40 Feet is difficult if passing through thick walls or steel buildings. If it is not an "N" router, then you need that or an Extender system. See TigerDirect for hardware replaements.

CONTINUAL DISCONNECTION OF WIRELESS CONNECTION
There are a few things that can cause you to lose wireless connection with your wireless router. 1. Weak signal strength, check the signal strength on your wireless card. If it is weak move the wireless router away from brick or concrete walls and if possible locate the wireless router higher up. 2. Have you secured your wireless router from people near your from unauthorized access? i.e. change the default password, setup encryption use WPA2 or WPA, change the default SSID, and turn off SSID broadcast, and for added protection, enable MAC address filtering which allows only the MAC address/es of your wireless card/s to connect to your wireless router. 3. You could be getting interference from electrical sources such as air conditioners, arc welders, washing machines etc. If so, the power supply to the wireless routers and computers etc should be connected to a surge protection power board, better still connect your computer equipment to an UPS (Uninterrupted Power Supply). 4. Check the channels of the wireless routers and access points in your area and change the broadcast channel on your wireless router to an unused channel or one that is currently used but has the weakest signal strength. This will minimize interference with your wireless router from other wireless routers and access points in your area.

Check the configuration of your wirelss router.

first i would download and install this program http://www.xirrus.com/library/wifitools.php that will tell you all the networks being broadcast and what channel they are on ideally you want to be on channel 1 or 6 or 11 - as they do not overlap
you should be able to download a manual from here http://www.buffalo-technology.com/support/downloads/
you need to login to the router and then goto the wireless section and changed the channel there

Hi,
Routers generally have a strong signal for up to 10 meters. However no obstacles should be in the way. 30 feets is about 10 meters so the router is loosing its signal strength. If you would like to extend the strength of your router you can buy a range expander. This device acts as a repeater of the signal so from 10 meters you can go to 15 or 20 meters.

if you arent in a clear line of sight, many things can affect the signal strength of your network including the thickness of the walls, the composition of them and anything else that may be in the way. if you use a 2.4 ghz router and you have a 2.4ghz cordless house phone, they can interfere and cause issues. A microwave oven that is located between the router and a device can cause interference as well.

I've seen this on a router that was broadcasting very little signal. (in my case the next day it died. When the laptop is running move away from your router and try to determine where it loses signal strength. A router is good from the factory for about 200 feet with no obstructions. In most homes I give them 30 to 40 feet. Be aware that windows and glass doors nowdays use a metal mylar film between the glass to reduce infrared rays. If you lose the signal very soon then I'd say the router is dying.

Good Luck

It shows that your wireless router and wireless adapters are both working. One thing to try is changing your wireless channel. Since you are already using 11, try maybe 1 or 9. Check if your SMC adapter will pick up the wireless signal.

By the way, how far is your computer (using the SMC adapter) to your wireless router?

Hi there!

Do you know how to check the wireless IP address at your iBook?
