Hi guys, i've encountered a weird problem, i've just come back from university and tried to set up my computer but for some reason cannot connect to the internet. There were no problems when i last came back about 2 months ago. Its connected to the router (bt homehub 2.0) with 3/4 bars but has a little warning sign and when i run troubleshooting it says "the connection between your access point, router, or cable modem and the internet is broken", all the other computers in the house are connected fine and strangely when i run diagnostics and reset the router the connection works fine for around 5 minutes then i get kicked off and the warning sign appears again. does anyone have any idea how i might fix this? Thanks very much!

My computer is a dell xps 8500 with windows 7 and this is what came up when i did ipconfig /all :

hello there,
Can you do me a favor first? if this is possible, please connect your computer with cable to the router and from the router to your modem or wall port for internet. See if this gives you internet.
Second, see if other network devices can access the internet with this wireless internet connection. Try this one first then the Cable.

I want to know where the problem is. If you say like for example Cable works, but other devices with same network wireless access doesn't work. Then i can say that wireless is either bad configured or something else happening with wireless. Then i can continue to help you.

I'm an IT student who works specially with Teamviewer to access peoples computer to help them fix such issues when it's possible and needed.
Teamviewer is a software to share screen and can take over the computer while you can see what;s happening.

So neither with cable or wireless ? . Well i don't expect you can re roll your computer to 2 months ago.

So there is a few option left.
Make screen shots about the warning message of it and transfer to another computer by ?USB and upload it here.

Or

Can you download this file http://www.dell.com/support/drivers/us/en/19/driverdeta... and save it on your USB stick so you can run it later?
On this computer where the problem lies, can you click on start then right click "Computer" and select "Manage" . Click "Device manager" then right click the Wifi ( W Lan ) one and uninstall? when done restart and see first if it auto detect, if not or fail, uninstall and install the one on your USB STICK. And keep us update.

After this we gonna check further for Wireless disturbance nearby such as metal etc ...
Also for the settings... but as i see here from your ip config /all, i see no problem.

Have you set you PC to use a certain IP address (for example needed to port forward and assigned it a certain ip every time it boots) because some routers don't support that function.

Typically, the situation you described is indicative of DNS resolution errors. With Windows 7 you may need to manually set your DNS server(s). Better routers will act as intermediaries between your computer and the DNS servers and thus your DNS address will be the same as your router’s IP address, but in Windows 7 (observed) this relay can break down.

Manually configuring your network connector to use your router and your DNS server should resolve the problem. The DNS server IP-Address should be specified by your ISP, but some third parties do exist if you want to experiment.

OpenDNS: 208.67.222.222 and 208.67.220.220

Google (Public) DNS: 8.8.8.8 and 8.8.4.4

To Configure your DNS Server on the Windows 7 Machine:



Control Panel > Network and Internet > Network Connections > (Select your Adapter) > Properties > Internet Protocol Version 4 (TCP/IPv4) > Properties > “Use the following DNS server addresses:”

Specify your Router, and your DNS Server

Should this not resolve your problem, please post the configuration details of one of your functional machines (computer preferably)

Though so Your ISP has probably disabled Manuel DCHP it causes me a problem when I go between my house and a friends as I have a custom DCHP for my laptop due to port forwarding . Glad you have sorted it :)  Fingers Crossed it doesn't reoccur

Hello...

I have same problem,
I think that you need to free your mac Address.
Please Request your ISP(Internet Service Provider) to free your MAC Address.

i request for it and Now internet is working fine in my laptop.

Thank you c3h8- I had an issue with my laptop not connecting to the internet. I could connect to the router, connect to the internet via ethernet cable and other devices could connect to the internet. After doing various troubleshooting and potential fixes I stumbled across this and tried it on my laptop and it works fine now- thanks so much!
