Yes. There are loads of different ones on the market, from internal ones to external ones.

How do you find your router ip address?

I'm assuming you use windows, and the router is up and running and in use. If these are both true, type "ipconfig" from the command prompt. This will show up:

Connection-specific DNS Suffix . :

IP Address. . . . . . . . . . . . : 192.168.0.100

Subnet Mask . . . . . . . . . . . : 255.255.255.0

How do you open my wi-fi password?

That depends on your router. You'll need to access your router settings and turn off WEP/WPA or whatever security your network uses.

However, keep in mind that some ISPs may consider unsecuring your wireless network "assisting others to steal cable service" even if you have DSL, satellite, or some other form of internet that doesn't come from a cable modem. Also, you will be liable for any abuse coming from a third party accessing your network, such as hacking, spamming, etc. In addition, you're personal information will be easier to hack as data sent over the network will not be encrypted.

What is the difference between access point and wireless bridge?

A wireless Access Point (AP) connects a group of wireless stations to an adjacent wired (Typically, Ethernet) LAN. An AP is like an Ethernet hub - except that a hub relays LAN frames only to other 802.3 stations, whereas an AP relays 802.11 frames to all other 802.11 or 802.3 stations in the same subnet. (In English: "it allows communication between wired and wireless..") A wireless router connects a group of wireless stations to an adjacent wired (Typically, Ethernet) LAN. A wireless router is a wireless AP combined with an Ethernet router. A wireless router forwards IP packets between your wireless subnet and any other subnet. Most routers also have a built-in firewall, and built-in Ethernet ports. (In English: same as an AP, but you can network different subnets or networks (Example: your home network and the Internet [Modem also required typically!] )

If you don't have access to a WAP (wireless access point) then you will need to configure the laptops to work in ad hoc mode. In ad hoc mode, one of the laptops will be the "host", other laptops will be clients. You need to use the same SSID (service set identifier) for all the laptops. I presume you're asking about Windows laptops; with Windows Vista, it's fairly straightforward: # Select Connect to from the start menu.

# Click Set up a connection or network. # Click Set up an ad hoc (computer-to-computer) network, click Next, and then follow the steps in the wizard.

Turning up the transmit power or utilizing a highgain antenna to reach wireless users from a distance increases your exposure to?

Turning up the transmitter power is a good way to insure that more cellphones, farther away, can hear the base station. But it doesn't to anything to help the base station hear the cellphones that are farther away. The only way to increase the coverage range reciprocally is to do something with the antenna. But that's a catch-22 . . . a higher-gain antenna has a narrower beam-width. So it works farther out, but only through a narrower 'window' of directions.

Place the following networking technologies in the order of their highest speed from slowest to fastest Fiber optic dial-up networking cable modem Fast Ethernet?

Telephone Lines : 56 Kbps


The question states SLOWEST TO FASTEST so it would be in reverse order:


Telephone lines: 56kbps, ISDN: 64 Kbps to 128 KBps, SDSL: Up to 2.3 MBPS, Cable Modem: 512 Kbps to 5 Mbps, ATM: 25, 45, 155, or 622 MBps and Gigbit Ethernet: 1Gbps
