Laptop will not connect to the internet?

Question

Hi,
I have a problem, My Internet on my PC works fine, also i am able to connect to my internet wirelessly through my iPhone, so my internet works. Now my laptop just will not connect although it says i am connected, and i have an excellent signal strength and status is connected, Speed: 54Mbps. I still cannot surf. I think it may be a DNS issue or IP issue, i have Renewed my IP by using ipconfig /renew through cmd.

Answer 1

on the side at the front of most laptops there is a wireless on off switch, i'm a bit of a nerd and felt so stupid when i had to bring it to best buy and tell me what the problem is :P

Answer 2

Have you tried getting windows to repair the wireless connection? If it is a DNS or IP issue, Windows should be able to resolve it. Also does your laptop have more than one wireless internet profile? If it does it could cause a conflict and cause your IP to not work. If your laptop has Windows Vista make sure your router has the suitable security I think it has to be WPA2. If none of this is useful connect your laptop through the LAN cable and then go to your device's and driver's and unistall it, restart your laptop and then re-install it. It worked for me. I also found when I had a DNS problem windows live messenger sign-in assistant helped me by giving me an error code in which I looked up. Hope any of this was useful lol =)

If you are actually obtaining the ip address automatically, it has to be a machine setting. Right click your wireless connection and select properties. Then select tcp/ip properties. Ensure that all the settings are for obtain automatically. If DNS is not set to auto you can not browse. In Internet Explorer go to tools/internet options/ connections and ensure that never dial is turned on. Then in lan check that ALL the check boxes are turned off.

Try refreshing the system by turning everything,including the router,off.Then turn the router back on,but connect the laptop first.If you still have a problem,open Internet explorer.Then under the "Tools" menu select "Diagnose connection problems" & allow Windows to attempt to correct the problem.If the matter is still not resolved you will have the option to view a report of the exact nature.Take it from there or repost on here.Good luck!!

Answer 5

Try checking your firewall or what ever AntiVirus/Spyware software you might have and check if its blocking your internet traffic (Usually known as 'Panic Switch'), if it is then just allow traffic. If that isnt the problem then all i can suggest is to turn your router off and all connections from your laptop, turn on router and make a new Wired Connection using an ethernet cable... if this allows your computer to surf then change it to wireless.

Hope this helps.

Answer 6

well what you can do is disable the wireless and try to powercycle the modem and the router you have to do the modem first so you would shut down all comuters then unplug router and rest modem frm the back unless u have the rest button on the front of the modem then let it boot up for 3 sec then plug in the router turn on only ur computer and enable ur wireless card and see if it will let you connect now is this a open network or secured?

Answer 9

I had this problem. Assuming you use Windows Internet Explorer, try reinstalling it simply by choosing "Tools" from your browser toolbar; then choose "Internet Options", choose "Advanced" then towards the bottom of the window choose the option "Reset Internet Explorer Settings". Then let it guide you through. This fixed it for me. Sorry, can't help if you're using something other than Windows Internet Explorer.

Answer 10

Turn off your modem and back on again, finally restart your computer. This will refresh the ip or flush it i should say.
