Wireless connection will not let me surf the net.
Sorry this is going to be a long answer, would be easier in a real time talk, please go one by one on my suggestions to pinpoint the problem and thank you for your patience in advance :)
Start your internet explorer/firefox, go to google main page, type something into google that you search for and click search. The reason for this is: the main page can load from an offline cache file, seeing the main google page does not mean you are really connected to it. Only if it finds results on a search.
If giving in a search word and clicking search results with no page is displayed you are either offline in your browser settings, not connected to the internet or you have browser problems. So let us check which one. :)
The browser is easiest to check, click your file menu, and down at the bottom where it says work offline. If there is a little check, untick it. Since you say however, that when you connect with cable it works I will assume that the work offline is not checked. So I will guess for the first option, that you have a network issue, so I carry on with this option.
To try to troubleshoot this, click on your start menu, select the option RUN, type into the open field: cmd
Then click ok.
It will open a black dos window. In the window, please type (after all the text that is written in it):
Then hit enter. This will provide you with some information about your connections. Search for the line telling you the IP address your computer is currently using. Based on what the IP is there are the following options to go:
1) If your IP address starts with 169.*.*.*, then your computer seems to be ok, your network card etc works but you did not get an ip from your wireless router though are able to connect to it. Please shut down your computer, go to the router/modem, pull out the power cable from everything and count to ten. Then plug back in the power cable, wait till all lights on the router/modem go green and start up your computer again, and see if the problem is resolved. If not resolved, check for IP again (see above, with the cmd, ipconfig). If still starts with 169, contact your internet provider and complain that you have problems accessing your router wirelessly and you receive no IP address. They are responsible for your router and they can diagnose it remotely through the connection they have to it. This way you find out fast if it is a router problem. If it is your own router, please provide router brand, type, etc some sort of number so I can look up potential problems with it:)
2) If your IP address starts with 192.168.*.* that is half ways good news, because it means you did receive an IP from the router, so at least to the router you connected. That means again card is ok, your wireless connection to router is ok, you can not browse though so let us see if there is data transfer going through, Go to start menu, run, type in again: cmd
In the black window now type:
Now hit enter. If it says that it can not resolve the name, then you seem to not even be able to resolve hostnames. Again call your internet provider, that while you are successfully connected to your router wirelessly, there is no data transfer through it. Please do make sure you tell them the IP address and that it works with cable. If ping google does give you a line saying it can ping it, then look underneath it for how many packages are sent out and how many arrived (ping statistics). If four sent and none arrived, again it is an issue with data transfer, try turning off the router and back on, try again, and if it does not work call the internet provider.
If ping statistics says four packets sent out and four arrived :
Pinging google.com [220.127.116.11] with 32 bytes of data:
Reply from 18.104.22.168: bytes=32 time=201ms TTL=236
Reply from 22.214.171.124: bytes=32 time=196ms TTL=236
Reply from 126.96.36.199: bytes=32 time=196ms TTL=236
Reply from 188.8.131.52: bytes=32 time=194ms TTL=236
Ping statistics for 184.108.40.206:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
This means you can ping google, so definetly you are on the net, then back to the issue of your browser being unable to go out. Then please get back to me we WILL solve that, but I need to ask you questions then.
3) If your IP address is NOTHING or 0.0.0.0 then either your card is disabled or dhcp client is not running on your computer. You can check this by clicking start menu, control panel, system, hardware, device manager -- go down till you see the icon for network adapters, open the option, look for your wireless card and see if it has a red cross on it or an exclamation mark. If yes, right click on it, go to properties and at the bottom choose: ENABLE.
If it has no red cross/exclamation mark, then check for the dhcp client service.
To do that you have to click on start menu, control panel, administrative tools, services, and in the list search for DHCP client. If you found it, select it and right click, then choose RESTART or START if it is not running. Once it runs, try reconnecting to the wireless and check for your IP in the black window again, if it now changes to something.
4) If your IP address is none of the above but some sort of number for sure *.*.*.* that means you are on the net, you have internet IP, and yet you can not browse. Try the ping google test, and based on the results if you DO get four sent, four received, get back to me, if four sent none received, reboot router and try again and call Internet provider if still not works.
Please get back to me about which of the above happened or if this solved your problem. If none of the above solved, please provide information what your computer said at which step and we will go on on that lead. Sorry for the long answer again, but network problems can have multiple reasons:)
If the solutions did help please rate :) and let me know :D
