What does it mean to enable AP mode in net gear wndr3400 router?
This means that the device will no longer be a "router" ... it will simply pass through IP addresses in the same subnet as the one it is given (presumably by an upstream router). This is useful for networks where there is an existing router (e.g., uverse gateway) with built-in wireless, but you want to locate the wireless access point in a different location from the router.
Note that a router would typically have an IP address in one subnet (provided by the WAN or an upstream router) and it would provide IP addresses using DHCP typically in another subnet.
So your cable modem is a router in that it gets an external IP from the cable company. But then it provides 192.168.x.x addresses to you. If you add an additional router it might be given a 192.168.x.x address and then provide 10.1.1.x addresses to you.
If the additional "router" above were in "AP mode" then it would have a 192.168.x.x address and it would pass through DHCP requests to the cable modem... so everybody would get a 192.168.x.x address.
Is there wifi on southwest airlines?
Southwest is adding wifi to more planes all the time. They don't expect to have wifi on all flights until 2012.
Do you need wireless internet to go online with a ps2?
With the PlayStation 2, internet access can be enabled in a variety of methods, the most common of which is through a wired connection. Using the ethernet port on the back of the PlayStation 2, one can connect the PS2 system to the internet. However, if no ethernet connection is available, some third-party wireless adapters are available that can be used with the PS2 either through the USB or ethernet port.
How does the wireless Internet work on laptops?
In simple terms, you have two hardware devices that make up wireless connections. First, you have a Wireless Access Point or AP or WAP. A wireless access point is simply a wireless hub. An AP has antennas for sending and receiving the wireless signal to other wireless devices and it also has a cat 5 connection for connecting to the network.
The other device is a Wireless NIC. Wireless NIC's are manufactured for both desktop and laptop applications, however, the laptop NIC's are more popular. The wireless NIC's have a built-in antenna and it is also sends and receives signals. 802.11b/g devices send and receive at 2.4GHz.
Absolutely fantastic! A friend of mine would bring over his laptop & while I sat with my desktops poorly performing internet connection, he'd be connected through a anonymous IP that was lucky to have been useful in getting his Apple Mac online & with great download speeds. Lucky, considering that they somehow had their radiation permeating into the inner spaces of my home.
In fact, I should investigate whether or not the dangerous, brain zapping, wireless radiation is still violating the spaces of my inner sanctum. Imagine that, it's their produced & marketed product, yet my private property is infiltrated by it without any benefit produced other than the billions they rake in while emanating their intrusively trespassing, dangerous radiation
Honestly, I am going to wrap some tin foil around my head and pray the aliens don't get me.
What are the different functions of bridges?
Some bridges are for walking or riding a bicycle on (known as footbridges)
Larger bridges usually will accommodate automobiles (including trucks)
Some of these bridges may join highways to major streets or to other highways (called overpasses)
Long bridges that span over waterways may lift to allow a boat to pass underneath them.
Some bridges are simply meant to be admired and serve no function otherwise.
Another type of bridge is used for networking. It is usually referred to as a wireless bridge.
Wireless bridges are used to boost the range of an existing network.
What does the WPA key mean for a ps3?
Actually, it's closer to a passŵord (methinks), & it's used to connect to the internet via a given router [the wi-fi & lan device with all the lights (either still or blinking) & the phone cable slots]. Said WPA key can be found on the router's relative documents or even on the thing itself.
How do you connect your ps3 to Internet apart from wireless?
You can go into system link, which is multiplayer to play with friends around you. That answer does not make sense to me but could be accurate.
As far as I Know. Without the internet you can only play people next to you with there own controller on your console and you can call it co-op split screen or multiplayer that depends on what the game allows. I was surprised when I learned how many games could only play against someone online and not on the same console.
Who invented the wireless keyboard?
Though I'm not sure who actually invented the wireless keyboard, one of the first wireless keyboards was part of IBM PCjr in 1983.
The Internet is a WAN. It "INTERconnects NETworks" over the widest area possible, the Earth.
What is the purpose of routers?
Routers are responsible for delivering and receiving network communication. They regulate what goes in from either "leg" of the router and what goes out of either "leg". They can also be configured to send specific data through specific routes, hence the name.
The purpose of routers is to take the signal that is being sent via the cable wire and convert it into a wireless signal that multiple devices can connect to.
DWDM (Dense Wavelength Division Multiplexing)
"WI FI" is a neologism (new word) that represents a play on the old slang "Hi Fi", which originally meant "high fidelity" (music) and was generally applied to phonographs and the vinyl records played on them. "WI FI" would therefore be "wireless high fidelity", consisting of broadband wireless routers used privately or publicly to connect computers at high speed.

Which layer of OSI model determines the type of communication?
The OSI model is a general model for networking . It has seven layer in total and each layer have some responsibilities. The layer that determines the communication mode is physical layer.
What is a ssid and its wep key?
An SSID (Service Set Identifier) is the name of a wireless network that identifies it to users and devices, allowing them to connect to the correct network. A WEP key (Wired Equivalent Privacy key) is a security key used to encrypt data transmitted over a wireless network, providing a level of protection against unauthorized access. However, WEP is considered outdated and insecure compared to more modern encryption methods like WPA2 or WPA3.
How do you find the wep key on the router?
WPA/WEP is the encryption setting and is configured on the wireless router. The use of WEP is not recommended because it is extremely insecure. A WEP password can be cracked in a matter of minutes, or even seconds if there is enough activity on the network. Use WPA!
I have a similar problem with my new laptop. In my case, I believe that it may be because I might have accidentally disabled DHCP or DNS on its wireless adapter while adding a wireless router to my local area network.
I can see all my PCs from any other in my LAN, and connect to the internet with all of them, including my laptop. But after I turn off my wireless router, I can no longer use my laptop to get to the internet through any free wi-fi hotspots the way I did even a few minutes earlier.
I am, of course, trying to resolve this problem. Stay tuned and I'll keep you informed.
Follow up:
I found excellent advice at: http://www.cabnr.unr.edu/IT/Wifi.aspx It turned out that I should not have specified a particular gateway in the settings of my wireless network card as I have enabled it for getting DHCP automatically.
Disadvantages wireless sensor networks?
One of the biggest disadvantages of large scale wireless sensor networks is the fact that they are vulnerable to unauthorized access. Also it relies on the complexity of logistics involving selective replacement of sensors.
