Question about Linksys WRT54G2 Wireless Router

Problems with WRT54G2 and DNS

I have a Linksys WRT54G2 router set up at my house. My computer detects it but for some reason I can't connect to the Internet. I can get on my router's page, but the wireless network just won't work. When I click "diagnose and repair," the same error message keeps coming up: "There may be a problem with DNS configuration..." In the router page under "Status" and "Router," the IP address, subnet mask, and default gateway are all zeros. There isn't even any text for DNS 1, 2, or 3. If it makes a difference, I'm running under Vista.

    I tried doing that but it didn't work. Now, I have the same problem as before where I hook the router up (even my iPod detects the wireless network), but there is no internet connection. The desktop I have the router connected to has internet access, but I can't get to the router page. Under ipconfig in cmd, it says that the IP address is 24.63.15.90, and when I type it into the address bar it doesn't work. In Network and Sharing center, under manage devices, the WRT54G2 doesn't even show up.

Hello,

It sounds like your router is not getting an ip address from the modem. Try powering off both router and modem, power the modem on first, wait about 2 minutes then power on the router making sure the ethernet cable is connected to your modem. Once the router is up and going, check the router's setup page and see if you have an ip address. Post your results here when you are finished.

Good Luck

If there is only zero on the ip add, sub mask etc then it would never work.Make sure your router is connected to a modem and that the latter can be hooked directly to a pc with cable and test if there is an internet connection. If there is a connection go back to your pc and connect to your wireless.Then go to start>cmd, a black screen would appear and type the following : ipconfig /iprenew .Then afterward type ipconfig and see if the zeros' you mentioned earlier changes to a value to the format of x.x.x.x .This should solve your problem.

    If the desktop has internet access but cannot log into the router setting then it may be your wiring connection here.Which means that it is possible your ethernet cable is connected to the modem but not the router as else it should see its settings.As a test,remove the ethernet cable from the desktop(I assume your desktop is hard wired to the router) and plug it to the laptop and see if you have any connection.If you have then it is definitely the router.Try to reset the router and check all cable connection and allow a reset of the router and modem by turning both off for few minutes.If this does not help then you have a problem with the router itself and I will suggest ebay.com for a cheap part, may cost less than 5 usd...Hope this helps, for any question please do ask.

    Unplug ethernet cable from destop(assuming your desktop is hard wired to the modem) and plug iinto your laptop.Test for internet connection.If you have one then go back to your wiring connection from modem to router and check..Make sure they are all connected in the right place.Then try a reset of both router and modem by turning off for few minutes, the former may have a reset button key somewhere on it,so confirm this from its manual and reset.If you still do not have any connection then you may need a replacement router which could be less than 5 usd from ebay.com.Hope this helps.

Hi

The Router configuration is not that much difficult, only few thing you have sure,

Follow the mention bellow instruction to configure and connect to Wifi Router,

  • Plug the network cable ( Mine was Blue ) which comes with the Router Box pack to your computer. The other end goes into any of the Router Ethernet Port ( 1 or 2 or 3 or 4 )
  • Now type in 192.168.1.1 in IE or Firefox or any browser. You will prompted for password which is admin. You must be logged into Linksys Router.
  • Now since your ADSL modem is also having the same IP , we will change the IP address for WRT54G2 Router to 192.168.5.1
  • Under Setup >Basic Setup look for Network Setup and Change Router IP. Change to 192.168.5.1 and Save changes.

WRT54G2 wired desktop fine, can't connect to wireless.


Hi Seth6025,

Try without using Wireless Encryption (password).

Try changing channels; default is 6; try 1 or 11.
Change your SSID: personalize it
SSID broadcast: Enable

Check the advanced wireless settings and make sure MAC filtering - DISABLED.

Reset the Linksys router by pressing RESET for 30 seconds should everything fails and re-configure. Firmware is another consideration BUT this is just a new release.

Regards,

Angel

Linksys WRT54G2 Wireless router unable to connect to Internet


Try again by Disabling the WEP (or WPA), MAC Address Filtering and Firewall Setting Individually. Should be a problem with one of those. Then when you receive the Signals, try to Adjust using Bottom Up method. That means one setting at a time, Hardening the Security. Have you checked your DNS settings? Have you checked the Channels you are using? Re check them and try again.

Setup linksys wrt54g2 broadband router with prolink h9200 modem


You probably will need to make some configuration changes in the Linksys router, or in your computer, or both. Your are correct that you connect the Linksys WAN connection to the LAN connection of the modem. If your connection type is PPPOE, you will need to set that up in the Linksys with the username and password provided by your ISP, so the modem will allow you to login and connect to the internet. If that is how you were connecting to the modem with your computer, you will need to configure a new LAN connection in the computer in order to connect to the Linksys. You can then configure the Linksys through your web browser to connect to the modem.


If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!
