Try to update firmware for your router, also you might think about relocating the router.
If you do not see signal from your router, it means that the signal is not strong enough an you need to get a wireless extender or a better router.
Could be interference. Wireless G routers use 2.4 Ghz, some wireless phones also use that frequency. Could be interference with another router, too. Could be weak signal, or if there's metal in close proximity, especially a chain link fence.
A wireless repeater is simply a device that receives wireless signals and repeats the signal to extend the distance the wireless signal can travel. The end result is that devices can be used further away from the wireless router.
Usually you do not have to do that. Either your wireless adapter is relatively weak your router. If your router has movable antennas see if you can adjust it to get better signal.
You need to update firmware. If you have done that already, then you are out of luck. DIR-655 is well-known for dropping signal. There is nothing you can do to fix it.
A Wireless N router simply uses different types of Hardware, the exact piece is called a N Connector. This allows for the router to not only put out a wireless signal, but it also allows for the router to receive wireless signal. This works great for computers that cannot pick up wireless signals normally.
A wireless router takes your Internet connection from your modem and splits it with other computers on your network. The stronger the wireless router the better the signal you will receive. The stronger the signal the further you can be from the router and receive an Internet connection. As good as a strong signal sounds you should consider that your signal can be picked up your neighbors and passers by who may try to access your network.

yes, if the receiving router has a "bridge mode" available. With this mode a wireless router can mirror data received from a far away router to the local area covered by it
to turn off the wireless signal, you only need to unplug the router. if that is no good for your purposes, go to www.whatismyip.com and type the IP it gives you into your address bar. this redirects you to the router setup, where you may be able to turn the wireless signal off
No, With most wireless cameras; they rely on a wireless routers signal to work.
Wireless routers connect to the modem through an Ethernet cable and also use a power cord to power the device. The Internet runs through the modem into the router. The router transfers the Internet into WiFi signals that the wireless receiver catches and transfers to the computer. Wireless routers have various signal strengths. The signal strength determines how far you can be from the router and still receive a WiFi signal. the N router transmits a strong signal that can reach throughout your house.
