i have problem with my wireless connection, all of the sudden my wireless router (linksys wrt54) stopped working, so i decided to exchange it for a new one of the same thing, got home and installed my wireless router and nothing, so i went and got a D-Link wireless router. my computer says its connected to the wireless internet but i can't open any web peges or anything when i try to log on to msn messenger i get that i have a DNS error but i have no idea on how to fix it.. thx for the answers but i still have the problem, it' says im connected to the internet but when u try to open a web peges all i get is "Error Loader" when i go to msn messenger it says i have a DNS error and the key ports aren't open Let's cover what you need to get Internet access to more than one computer at home, via wireless LAN (local area network).
The concept is the same for WIRED networks. Add Cat5e Ethernet cables and Network Interface Cards (NICs), instead of wireless adapters to each computer. You can use a wired router instead of a wireless router if you plan on being wired only. Treat an Xbox 360 just like any other computer. Xbox 360 needs a wireless adapter too.
1. You order or use your existing Cable, DSL, FiOS, Satellite, or Tin Can Internet access, doesn鈥檛 matter what brand of access you have or where you are located geographically in the world. An Ethernet TCP/IP based LAN is the same in China as it is in Germany.
2. Your Internet Service Provider sets up your Internet access and typically either rents or sells you a network bridge. They often refer to this as a 鈥渕odem鈥? Actually a complete misnomer since the device does NOT MOdulate or DEModulate.
Prices for residential 鈥淗igh Speed鈥?Internet access vary from approximately $19 per month for low end DSL to $200 per month for the fastest FiOS option in the United States. This varies based on bandwidth, location, and provider.
At this point you have what is commonly referred to as 鈥淏road Band鈥?or 鈥淗igh Speed鈥?Internet access, basically meaning it isn鈥檛 dial-up or ISDN.
Now you want to share that 鈥渉igh speed鈥?connection with more than one system. You want to be able to cart your laptop all over the house and stay connected to the Internet as you roam the house and back yard. Yes this will slow everyone down a little bit, but it's really your only choice at home. It is a shared connection. When you and your house mates are downloading at the same time you鈥檒l notice a lower download speed.
1. Confirm that your system has a wireless adapter or get one and install it. It is a hardware device you can buy at CompUSA or Best Buy or your local computer parts store. Costs vary depending on the brand and type you buy from about $20 for a refurbished 802.11 g model to $80 for the top of the line 802.11 N draft 2.0 types. You need one of these for each computer. USB type are better because you can use it with a laptop or desktop without opening the case to install it. You can also use one USB type with multiple computers at different times. USB type that are 802.11 n Draft 2.0 that are Wi-Fi certified are the best.
2. Get a wireless router. I recommend the D-Link DIR-655. Cost is around $140 or so. Get D-Link n series USB wireless adapters if you get the D-Link wireless router. If you get a Netgear wireless router, get Netgear wireless adapters. They work BETTER together if they are the same brand. This isn鈥檛 a requirement, merely a suggestion.
2a. If you are setting up a WIRED LAN I recommend Netgear routers and switches. I have a Netgear switch that is still operational after constant use and abuse over ten years.
3. Plug the wireless(or wired) router directly into the Cable or DSL network bridge via an Ethernet cable. DO NOT plug your computer into the Cable, DSL, Satellite or Tin Can network bridge "modem". Plug your wireless router into it.
4. Unplug the electrical cord from your network bridge for 30-45 seconds.
5. Plug the power cable back in to your network bridge.
6. Check the network bridge for green lights.
7. Make sure that the properties of TCP/IP are set to Obtain IP address automatically, and obtain DNS automatically on ALL of your computers, your Xbox, and the router.
8. Turn on or reboot your system(s).
Now you should be able to stay connected to the Internet with all of your computers.
If you can not access the Internet from every computer:
Attempt to log in to your wireless router via your web browser (internet exploder or Firefox) by typing in (http://192.168.1.1/) This address may vary depending on the brand and model of wireless router you purchase. Check the manual for the default IP address and the username and password for your router.
Then log in (Admin and admin typically). Be sure to change the password to something of your own choosing that is LONG. I label the bottom of the routers I set up with the Username and Password using my P-touch. I also label the bottom with the WPA-PSK password. If you do this be sure not to cover the vent holes of the router with the label.
Enable DHCP on the router by following the instructions in the manual.
You only need one wireless router for you wireless LAN. One wireless router can accommodate up to 253 wireless computers. You can use combinations of wired and wireless routers together but typically one wireless router is sufficient for all your needs. In rare instances you may need a wireless router and a switch.
For SECURITY:
1. Don't announce the SSID of your wireless router.
2. Use WPA2-PSK if you can. WPA-PSK if not WPA2. WEP is too easy to get into. If WEP is your only choice I wouldn鈥檛 bother enabling it.
3. Input the MAC addresses of all of your computers into the MAC routing table of your wireless router and ONLY ALLOW from the addresses in the table of the wireless router.
4. Turn the SPI firewall of the wireless router ON.
5. Filter anonymous or incomplete packets.
6. Only assign the DHCP pool of the router enough IP addresses for your total number of systems. If you have 3 desktops, 2 laptops and an Xbox 360, you need 6 IP addresses internally, for your LAN. So set your DHCP pool on the wireless router to 192.168.100.1 鈥?192.168.100.5 for example.
If this all seems too complex and complicated to do, use local.yahoo.com to find a wireless network specialist near you.
This is Wireless for your home LAN. There isn't a wireless Internet. We just have one, Internet. Wi-Fi is a brand name like IBM. Check that your wireless tcp/ip information is set to automatic configuration. If this is a laptop, check that the card is switched on, they often have a tiny slide switch. Check if you can connect to the internet wired to the router. If so use your wireless card's utility to search for your network, set encryption and connect. |
