Configure an IP address on the relevant network interface and bring it up.

An open wifi access point is when your router can be accessed by joining with a wireless connection. This is done by not securing a router or allowing wireless connections without locking it from outside sources. Acessing a open wifi access point that doesn't belong to you is against the law and can be prosecuted.
Move the router to the middle of the house, or buy a better router.

Configuring a physical router requires software like PUTTY. while configuring router on Software like packet tracer is done on CLI (i.e. command line interface).
All layers - but to the greatest extent, the distinctive work done by the router - specifically, routing packets - corresponds to layer 3.
Technically, a router can be flashed and custom programmed to run faster, and have higher wattage for WAN. I would not recommend doing this, as it may burn up your router and turn it into garbage if not done correctly. I have done this myself, and use it as a paperweight now. So the answer, YES it is possible but not recommended.
Yes, you can do that. But it can be done only in series type connection not in parallel. Meaning that you should connect one of your router directly to the modem and another router connect to the first one.
First of all the router must be installed (the way this can be done varies from router to router), after that one must search for it with their computer and access it with a special key. That is roughly about it. More in depth info can be found at 'PCWorld'.
Multicasting can be done on a hub but a hub does not need it always. Configuring a router or switch to use multicasting requires that the router or switch be IGMP capable.
Your router has a feature that will allow you to attach a password to it. Contact either your ISP or router manufacturer who may have a URL for you to go to and actually change your router to password protected.
A wireless router bridge is a way to use an old or unneeded wireless router to extend the usable range of a central Internet access point. This can be done by connecting an older router to a functioning router and then either changing the wireless mode of the router to bridge, or by changing the firmware inside of the router so it can support bridging. The end result is a wireless router that will pick up the signal from an access point and provide Internet access to any computer that uses the wireless router bridge.
