Help required with internet connection (Dreaded yellow triangle).

Hello, firstly, I would like to state that this is my first post on these forums and I would like to note that while I will make an effort to abide by the rules of the forum, I may slip up. If I do just let me know.

Anyway, to the matter at hand. For over a year now, I have been using my Alienware M14x laptop, running Windows 7 Home Premium x64. Up untill now, there have been no problems with it's operation, least of all with it's internet connection. However just recently I have had a major issue with my internet connectivity. When I attempt to connect to my house's WiFi, I can connect to the router, however I am told that there is "No internet access" this is depicted by a yellow triangle the signal strength indicator, this prevents me from using the internet or any online functionality whatsoever. I have tried all of the obvious methods, such as resetting the router and rebooting my laptop. Additionally, I have tried all of the "ipconfig" commands in the console. However, that is the extent of my attempts to remedy this, as I only have a basic knowledge of WiFi/internet.

I have tried searching the web for a solution but to no avail. So I have decided to ask the Windows 7 community personally.

Also, many people with the same problem have posted their "postme.txt" files, so I will aswell, as it may prove usefull.

Any and all help would be greatly appreciated, as I rely on my laptop for my studying, as well as gaming (it IS an Alienware ).

Again, I would be very appreciative if someone could lend me a hand here, as ths is VERY frustrating for me.

:)

I would unplug the router, wait ten seconds and plug it back in. Wait a litle bit and then try your internet again.

@Havoc

Thanks for the reply. However, as I said in my first post: "I have tried all of the obvious methods, such as resetting the router", so unfortunately, this isn't the answer. Thanks for your input. :)

Okay your getting a valid IP from your Router
I would do an
ipconfig /release
ipconfig /flushdns
ipconfig /renew.
netsh winsock reset all
netsh int ip reset all
then reboot
Also have you done any updates, added or removed software?

@mrhiab

Ok, I'll enter those commands in tomorrow (it's late at night here) and see how I go. As for software or updates, I don't believe I've installed or updated anything.

Thanks for the reply.

Ok, I just entered in those commands bit unfortunately, the issue is persisting. If anyone has any other suggestions, I'd be happy to hear them.

Anyone else have any ideas? I would really appreciate I if s

Can anyone else give me a hand here? I would really appreciate it if someone could lend me a hand.

Can you tell me how many more of those tunnel adaptors are showing up in the ipconfig?

Have you tried disabling the Bluetooth connection yet?
