My internet will only work through ethernet cable not wireless?

Answer 1

The problem is that the DNS addresses for your wireless card are wrong. For most home installations these are normally set to the same address as your gateway address. In this case, 192.168.0.1.



You need to get into the Network and Sharing Center and open the advanced settings for the wireless adapter. Sorry to be a bit vague - the exact method is different for different versions of Windows. Once you have found the advanced settings, look for an item called TCP/IPv4 or a similar name. Highlight it and open its properties. You will probably find that the DNS server is set for manual configuration and the two addresses 192.168.4.100 and 192.168.8.100 are listed as manual configuration. Change the setting to get the DNS server addresses automatically, then click OK for each window that you opened to get here. At this point the connection should renegotiate with your router for the address information.



I have seen this sort of problem before where a piece of software has updated my DNS addresses without my knowledge or permission. You should probably perform a full virus scan and a malware scan at this point to see if any rogue software is detected.



I hope this helps.

Answer 2

Well your router is ok because you are connecting it through that I hope so I think its a simple corrupt network and if so it's simple to fix follow these steps

1.turn off the router and leave it off just now

2. Right click the wireless icon (bottom right of desktop)

3.choose network and sharing centre

4.from this in the left pane choose (manage wireless networks )

5.from this the networks should appear that the router can find

6.look for your network if it appears highlight it and I the bar above this choose(remove)

You want to do this to remove the possible corrupt network don't worry it will appear again but be properly configured

7.exit back to desktop and switch off laptop now switch on router let it load 2 mins then turn on laptop

8. Go back to wireless icon and right click again his time choose(connect)

9 your network should appear if so choose it add your password and that should be you be connected

Now tick both boxes when connected

*save this network and connect automatically

and you should now be connected

Answer 3

Okay usually when something like this happens it's a fault with shitty Windows, so avoid their forums like the plague because they are useless. In the last five years I have had zero help on those forums, instead finding answers on third party sites. For this problem you can try this:



You need to enable windows, or a third party software to configure network settings. Go to network properties and tick the box that says allow windows to configure. Or type services.msc in run and scroll down to wireless zero and start and set start up to automatic.



Also you could try updating all your drivers and this site has some useful info:



Edit: well there's always the chance that your router is broken, which is likely if the problem persists after resetting the router.

Answer 4

"Ethernet adapter Local Area Connection:

Media State . . . . . . . . . . . : Media disconnected "



This says the ethernet cable is unplugged. Are you sure you did it while plugged in? Based on the output above, your Wireless network card has all the correct settings, but your wired connection is not connected.



Edit: His DNS is not wrong. 194.168.4.100 and 194.168.8.100 are valid DNS addresses from his ISP, Virgin.

Answer 5

Double check and make sure that the External WIFI switch on your laptop is on and that you didn't accidentally turn it off.

Answer 6

may be your wireless card is not install or properly connected.
