    When plugged into the router (and I believe I have it connected correctly) I get low signal when I'm right next to the router and get an error being unable to connect via wireless. I take the same cable from the router into the laptop and internet works fine. Ideas????

    I had router installed with my cable modem for using our desktop (kids) and laptop (mine). It worked for two years and after a week of power outages, my laptop stopped connecting. Cable company did modem check and suggested unplugging router...My laptop connects without router through but through dial-up lol.

What internet provider are you using. is it verizon DSL or Comcast cable? 2 problems come to mind. the first is from your DSL or Cable box are you using USB or CAT5 cable (CAT5 has ends alittle larger than your phone wire)
If you have the CAT5 cable make sure it is going from your DSL/Cable box to the Internet connection on your router. you will have 1,2,3,4,5 ans one that says internet or WAN.
run another CAT5 Cable from your desktop computer to one of the 1 - 5 ports on the router. (If you do not have a Network card on your desktop you will need to install one.)

If all the above is correct and you have connection to your desktop and not your laptop please provide the Model number of the DSL/Cable box. some of the new boxes have a router built-in and cause issues. if the DSL box is a westell 6100. If this is the case I will provide detail on how to change your router so it functions as a switch to make it work. not hard to due but requires alot of instructions to complete.

Please understand as I get very basic to start but things very obvious to you I cannot see.

Generally when including a router in a home network starting from the cable (tv) or the phone socket (dsl) in the wall with a phone wire plugged in. The next box is generally provided by your internet service provider and is a modem/something that connects to the phone line or cable. Then sometimes when only one computer exists computers are directly connected to the modem with an ethernet cable (looks like a fat phone wire with oversize connectors) or a USB cable (small flat retangular ends).

When you want to add a router for multiple computers. The computer gets disconnected. If a USB cable was used it is often replaced with an ethernet cable and that cable connects to the WAN port (probably separate from a block of 4 lan ports) of the router you bought (tell me if you have two routers -- that is a different problem). If your service comes from a cable (tv) company your router may already be properly configured. If however you have DSL service from the phone company the chances your router is correctly configured are less. To finish with the cabling story -- your computer then hooks to one of probably 4 LAN ports all in a block. Now if you are lucky power on all devices and boot up your computer and see if you have internet access. If you do great if not please provide me the name of your internet service provider or a link to their help/support website and I will see what I can do to assist in completing the router setup. Until your wired computer gets access to the internet your girls wireless connections will not work either. Once we get the wired connection working we will address the wireless connections.
If necessary unplug the router and plug the computer back into the original cable until we get the router working.

    Jamie -- You have three major steps to complete --

    First is to get the router talking to the internet -- you say the wired connection works . I hope you only have one router, then if so this one is done.

    Second is to get the wireless adapters to talk to the router. To test if that is working I want you to do the following.

    Assure the wireless is turned on -- new machines have switches to save battery power when the wireless is not in use.

    Second -- test the connection

    On the wired machine first do the following

    Click Start then All Programs then Accessories then Command Prompt. A new window will open in that window enter the following command --


    and press enter. Assuming your router address is unchanged you will see 4 lines indicating success with elapsed times.

    Do the same thing on your daughter's machines -- let me know if you see a similar display or 4 timeout messages. If you get timeouts we have some wireless configuration issues to work on.

    If the above works then using the same command prompt window as above enter the following command (one space before / only)

    ipconfig /all

    In the display from your machine I expect there will be a DNS Address. In the Display form your daughter's machine there probably will not. Please let me know if this is so.

    I will provide detailed steps in either case depending on where you find the problem. If the first test fails the second test needs to wait until we fix the first issue.

    Flogger only --

    Check the bands for the wireless router/access point and the adapter -- they operate on bands A, B, G, N -- assure you have one in common. (may be OK not sure from your message)

    Keep router/access point away from wireless phone, etc. If you see routers in the area when trying to connect -- if you can see the channel they are on consider the following channels 1, 6, 11 are preferred. Choose one every one else is not on -- if you cannot tell try 1, if that does not work try 11.

    Probable bug -- do not hide network name (SSID) and use WEP/WPA security at the same time. Show network name (SSID) and use WEP or WPA.

    WEP or WPA encryption -- if you set it in the router/access point you must also set it to the same passphrase, password and key for the wireless adapters expected to connect.

    Lastly follow advice to Jaimee -- use ping to determine if you can access the router -- if it succeeds then wireless setup is fine.

    Use ipconfig to see if wireless has DNS address, if not DNS must go in router or TCP/IP config for the wireless.

    WEP or WPA encryption -- if you set it in the router/access point you must also set it to the same passphrase, password OR key for the wireless adapters expected to connect TO THE ROUTER.

    DNS addresses allow for the conversion of to an IP address for message routing which is why they are important. You can be connected to the router wirelessly and not be able to access the internet from a browser because these addresses are missing.

I just bought a laptop computer and I already had a desktop. My internet provider is Hugesnet Satelite. I bought a Netgear N600 wireless dual band router thinking I could just hook it up to my desktop...

The HN9000 should have an ethernet port. You will require two ethernet cables to connect the desktop to the router.
1. Connect the ethernet cable from the Modem to the Ethernet Input port on the Router (It is generally placed away from the other ports on the back of the router.) 2. Connect another ethernet cord from one of the output ports on the router to the desktop computer. 3. On the laptop, turn on your wireless card. The process for this differs from computer to computer. If you were to provide the model of laptop, I could provide you specific instructions. 4. The network setup should be complete.
If you need more help, let me know by replying to this solution. Thank you for using FixYa!

Make sure that your computer is able to go online through the modem.
If your computer is not able to go online through the modem then you will need to call ISP first.
If your computer is able to go online through the modem then you need to connect the computer to the router and the modem to the router.
open the set up page of the router and change the settings of the router according to the ISP.

Problem with sharing router

If you are referring to a cable modem then you may be talking about using both the USB connection and the Ethernet connection. They will not work simultaneously. But if you have a router and branching your connection, then there should not be any problems. Just make sure that when you are accessing the Internet through a router that you make sure that your router's IP address can access the internet after that you leave your computer's IP at Detect Settings Automatically, it works for me

I have a laptop comp i just got a desk top comp i have embarq broadband internet which comp do i pit the cd into to install and which comp do i hook up the embarq box to?

It sounds as though you will need to get router to allow the sharing of the Internet between the two computers. Using a router makes it much easier to share an Internet connection between multiple computers. You would connect the Embarq box to the router on the WAN port, and then connect your computers to the LAN ports of the router. You may also want to get a wireless router in the event your laptop has a Wi-Fi connection.

Pc connection problems

Sounds like you are setup to use Internet Connection Sharing. don't do this. Have each computer connect to the internet via the router. If the router is wireless connect all computers wirelessly to the router that are wireless capable and any computers that are not wireless capable, connect them to the router via a cat5 cable to the cat5 ports on the router. This will solve your problem. BPCS
