How does wireless routers work?

Question

Now I'm accessing internet by LAN connected to a ADSL router (not wireless).

I want to get a wireless router for wireless internet at home.

Question1: Is there a difference between "wireless router" and
"wireless ADSL router?"

Question2: After I buying a new wireless router, do I still need the old non-wireless one?

Question 3: For home using, which range / mode should I buy?

*******Thank you for answering and helping*******

Answer 1

To make it simple for you.



There is no difference between a wireless router and a wireless ADSL router. They're the same.



You have to be careful and ask the seller. Some label a wireless router as just a wireless attachment to a existing router. However it is recommended to get a wireless ADSL router where you don't need an existing router. Mention an 'all-in-one' to the seller and they'll know what you need.



For a home, with about 5-10 connections, I suggest getting a nice cheap router 802.11b/g such as a Linksys WRT54G, or a Belkin or Netgear router.



Why? These brands are aimed at 'computer novices'. Most just need you to plug it into power, access an IP such as 192.168.1.1 (or something like routerlogin.net - Netgear), click setup, insert your existing ADSL username and password, and you should be connected.



It's so easy, you'll want to do it again since it'll last about 10 seconds (setup). Trust me.



PS: I have no idea what oolp_4_l... is taking about. I don't think he has an idea either.



Wireless connections are slower compared to connecting by a cable, because wireless eonnections can only travel in one direction at a time. EG: You send packets over and then receive them. But they cannpt happen at the same time.



As opposed to being connected by cable, it can move back and forth simultaneously. This means that connecting via cable IS faster then wireless (by a few kb/s really) but wireless is NOT faster than cable.

An ADSL router is also known as a DSL modem. The router is used to connect the computer to the DSL phone line for using the ADSL service.



A wireless router is simply a router with a wireless interface!



A wireless router could be a regular IP router with an 802.11 interface card and antenna added, or it could be a router specifically designed for wireless use.



To answer your second question. The only way you would not need your ADSL router is if the router you you is a 2 in one ( ADSL/Wireless Router. . . . .



For home, i'd consider Linksys, or Netgear.

Answer 3

A router gives off a signal. You use an adopter that scans in a radius for a router's signal. This signal can be anyone, but one should be your router. You then connect with the router, the name is known as SIDD and then you type in your WEP or WPA pw to log on to that network.



No, I see no reason for the old one. All routers have ports in the back for hte ethernet cable. The new one would be the device giving out the signal for hte adapters to pick up.



Since it's home use a cheap one should be fine. I found a trick to increase internet connection. If your computer has a weak signal use longer attenats for hte router and the desktop adopter. It acutally works. Do change the Sidd and WEP/WPA to your desired name and pw. Most of the time the default pw is defalut and you don't want a stranger using your speed.

answer 1



ADSL router is faster..The newer, faster ADSL standard offering up to 24Mbps download speed and 1024Kbps upload..

but i dont know about wireless adsl router..



answer 2



No u dont..The downside with adsl modem/router devices is that if you ever want to upgrade either the modem or router capabilities to go wireless you are forced to replace both.



answer 3

Whether your PCs have wireless already or you plan to add this later, a wireless access point will save you time and money if you want to share your network connection this way. If the wireless router has an integrated ADSL modem, it can only be used to share an ADSL connection.



Three things to be particularly aware of when going wireless are signal strength, speed and security. Most domestic devices have a limited range, especially when one or more brick walls separate the computers from the router. Because of this, in larger properties it may be beneficial to use a separate wireless access point, rather than one that is integrated into an ADSL modem/router. This is because you can determine the best location for the access point by trial and error, without having to worry about the availability of a telephone outlet. A device that uses a separate ADSL modem won't face this challenge, but you will still need to run a cable from the device to the modem.



When it comes to wireless speed, there are four technologies worth considering. All share the name "802.11" but are differentiated by their operating frequency, throughput, data rate and range (indoor/outdoor). "802.11" is a wireless standard developed by the IEEE LAN/MAN Standards Committee and then adopted by device manufacturers. They are often referred to as IEEE 802.11. For the average consumer, the most important attributes to consider when purchasing a wireless networking device are indoor range and maximum data rate.



802.11a (Wireless-A) operates at 54Mbps maximum data rate and a range of approximately 35 metres. 802.11b (Wireless-B) can reach 38 metres but only has a maximum data rate of 11Mbps. The far superior 802.11g (Wireless-G) offers a maximum data rate of 54Mbps and can reach up to 38 metres.



The latest type of wireless is called 802.11n (Wireless-N). It is still under development but many wireless devices are already available that utilise it. In its current form it can operate at maximum data rate of 248MBps with a range of 70 metres.



Wireless-G and Wireless-N are both below the speed of conventional wired networking, but are still much faster than most ADSL connections. Wireless-G is suitable in the average home for connecting multiple computers to the Internet. However, wireless streaming over a/b or g networks can be problematic depending on the number of walls between the router and the destination device. Wireless-N is far more powerful and will suit larger homes or those with higher than normal levels of interference. Wireless-N is also more suitable for gaming or media streaming as it is more reliable due to its larger range and data rate. Some proprietary systems are available that offer a rate of 108Mbps, but be sure to get a router and wireless cards for all your computers from the same vendor, or else they will default to a slower connection.



802.11g and 802.11n include the newer WPA security model to secure your connection against neighbours from piggybacking onto your Internet connection or those with more malicious intent. WEP is the older security method - you should use it if you have no alternative, however be aware that the encryption scheme has been cracked and tools are freely available online that can be used to rapidly break into WEP networks. The newer WPA standard is only an encryption technology, however, so it requires an authentication process between your wireless access point and the wireless computers. WPA is designed to use a RADIUS server to authenticate users, but as this is beyond the needs and means of most home and small businesses, WPA-PSK authentication is usually available as an alternative. Here the PSK stands for Pre Shared Key and it simply means that you use a password. A non-dictionary word with plenty of characters including numbers and punctuation marks is recommended unless you plan on changing it on a regular basis.

Answer 5

now thats a good question

yes there is a difference.wireless router is more faster,has more range and rest u can read in the wireless router packet.



no u dont need the old non-wireless one.



it depends wireless is more better but is more costly..
