Question about Linksys WRT300N Wireless Router

1 Answer

Local access only

I have a comcast cable internet connection coming into a WRT300N. There are 3 computers that configured perfectly for wireless the first time and they work great. One is XP, one is Vista and one is Mac.

But we have two others that just will not work not matter what I do. One is a Vista and one an XP. Both appear to connect to the wireless network but have local access connectivity only.

The one computer that has Vista connects perfectly to my home wireless network and it is using the same cable and the same type WRT300N.

I am pulling my hair out and can use any suggestions.

    The XP that is working produces the following
    Access Type - Assigned by DHCP
    IP - 192.168.1.102
    Subnet - 255.255.255.0
    Gateway - 192.168.1.1

    The second XP is now working - operator error.

    The Vista has a different display and here is what it says if I am in the right spot.
    Connection-specific - hsd1.fl.comcast.net
    Description - Intel(R) Wireless WiFiLink 4965AGN
    Physical Address - 00-13-E8-0B-2C-63
    DHCP Enabled - Yes
    IPv4 Address - 192.168.1.104
    IPv4 Subnet Mask - 255.255.255.0
    Lease Obtained - todays date
    Lease Expires - tomorrows date
    IPv4 Default Gateway - 192.168.1.1
    IPv4 DHCP Server - 192.168.1.1
    IPv4 DNS Servers - 67.87.74.162 and 67.87.68.162
    IPv4 WINS Server - blank
    NetBIOS over Tcpcip Enabled - Yes

    Is that what you need?

    Actually, the wireless connection shows a good connection but "local" only. I cannot access the router with IE, can't access anything external with it. Outlook does not work, Opera does not work, FireFox does not work.

  • Lt Dan55 Mar 27, 2008

    All settings are as you specify.

    The error is "IE cannot display the webpage".

    If I click on Diagnose Connection Problems I get "Cannot communicate with Primary DNS Server."

    I stated before that I have the same setup at home but that was not quite correct. Last night took the Vista machine home. It connects just perfect and accesses the internet right away. BUT the router is a WRT150N instead of the 300. All of the settings are exactly the same as the router here EXCEPT the security type is WPA PSK instead of WEP. WPA PSK is not an option on the 300 here. Could that be the problem? Still, one of the vista machines works just fine on this router.

    Aaarrgghh!

    THANKS!!!!!

    Changing the protocol to WPA resolved the problem immediately.

    I appreciate all the suggestions and help.

    If i understand you correctly, the two computers you are having problems with are unable to connect to the internet, but can perform all local operations normally?  they can see other local computers on the network, can print to shared network printers, etc.?

    It sound like the two computers with problems have simply not been configured to use the correct routing through the WRT300N firewall...

    This will be easiest on the two XP machines:

    can you go to control panel, and then to the network connections window?

    if you double left click on the wireless network icon, and then go to the support tab, it should show you something like this:

    Address Type    Assigned by DHCP
    IP address         10.0.1.100
    subnet mask       255.255.255.0
    default gateway:   10.0.1.1

    (your numbers will probably be different)

    can you post those numbers, both from the XP machine that can connect to the internet, and from the XP machine that can not?

    Also, what tools are you using to access the internet? Just Internet explorer?  some other web browser? other software?  it could just be a problem specific to that software, instead of a problem with the network itself.

Hmmm... with those settings, the Vista machine SHOULD be working...

when you open internet explorer on the vista machine, can you go to tools, internet options, and then the connections tab?

along the bottom there should be an option for lan settings. click on that, and then make certain that 'automatically detect settings' is checked, and that everything else is blank.

then restart internet explorer.

what sort of error message do you get now, if you try to go to, say, www.cnn.com?

    ok... possible solutions if this is a security configuration problem...

    first, you can get the latest firmware for your router from this link:

    http://www.linksys.com/servlet/Satellite...

    Ok, so this vista machine WORKS with a 150N set to WPA PSK,

    but NOT with a 300N set to WEP?

    WEP is the older security protocol, and Windows vista can sometimes be finicky about connecting to a wireless network with less than ideal security settings....

    the first thing I'd try is updating the firmware and then setting to WPA PSK

    other questions:  if you connect the vista machine to the router using a physical cable, can you get online that way?

    is the router set to broadcast it's SSID?

    can you list what you see as the wireless security settings on both your (working) and (non-working) vista machines?

To connect to your wireless router, the router's wireless settings needs to be configured with the SSID, encryption etc. and also the wireless cards in all the laptops/computers needs to be configured with these router's wireless settings. Then the laptops/desktop computers can communicate with your wireless router.
Connect a LAN cable from the Linksys to the LAN port on your computer.
Open a browser and enter the Linksys configuration URL
http://192.168.1.1
The default login = admin

You can protect your router by changing the default admin PW (write it down and put it in a safe place)
Go to the wireless configuration and set up the SSID and WPA or WPA2 encryption to protect your wireless network and Internet from unauthorized access.

Have you secured your Linksys from unauthorized access?
The encryption code protects your wireless router from unauthorized access. The wireless card in your computer/laptop needs to be configured with the router's encryption settings before the computer/laptop can access the router.

WIFI not working with Linksys wireless-g broadband router/Comcast


Unplugging the wireless router and connecting it again should not have altered the wireless connection/configuration. You have connected the cables correctly because the Internet works when you connect a LAN cable to the router.
The Linksys wireless configuration or the wireless card configuration in the computer was changed it to lose the wireless connection. The wireless card configuration needs to be changed to match the wireless router's settings or change the Linksys with new configuration settings and configure the wireless card accordingly.

make sure your modem is connected to the INTERNET PORT of the WRT300N. wired pc must have an ip address of 192.168.1.x so we can say that the internet is really coming from the wrt300n

Use needle or pen to press it quiet hard for 1 minutes continuosly, This'll restore all default settings.

4. After that give static IP - 192.168.1.2 to your PC ,subnet mask 255.255.255.0 ,default gateway - 192.168.1.1 & connect your PC directly with a LAN port on the back side of Router.

5. After that type 192.168.1.1 in the address bar of your explorer & login window will come , type username = admin & leave password field blank, then you'll get Blue coloured Router configuration page, From this page you can configure your Router.

6.Now if your Internet connection is Cable then default setting will work for you, However for DSL connection ,on this page you'll find internet connection type - selectiondrop down box - select PPPoE into it for DSL connection.

7. After that restart your computer & you should be able to go online.

Configure WRT300N wireless Router to connect internet using PPPoE


Often the nets and subnets are NOT the same.. ie The Fixed connection often uses 192.168.0.1, 192.168.1.1, however sometimes the wifi is setup 10.1.1.1, or 10.0.0.1 etc, have you checked this? Esentially tho ya router is an "Acess Point" and ya Lappy etc is ya "Client" the links below has a lot of tutorials to help have a look. http://portforward.com/routers.htm http://portforward.com/guides.htm
