Windows 7: Getting yellow triangle over network icon. Some sites load, some don't

Upadating the driver may help.

Also open a cmd prompt by right clicking and choosing run as administrator and type:



netsh int ip reset reset.log press enter
netsh winsock reset catalog press enter
netsh int ipv6 reset reset.log press enter
nbtstat -r press enter
nbtstat -RR press enter
ipconfig /flushdns press enter and restart pc

Save and unzip then Run the 6to4 file first then reboot the machine.

Save and unzip then Run the IPreset file second let it run till your machine reboots which will be automatic, this takes about ten seconds. This is much easier than typing in 10 different commands.

After that open up Device Manager go to Network adaptors and disable the Microsoft WIFI miniport adaptor which is famous for creating connection problems.

Can you also disable the Bluetooth adaptor I see there unless you are actually using it for something?

After that please post a screen shot of your ipconfig/all, it's best to use the snipping tool for this rather than copy paste.

Thanks guys! I tried both of your suggestions, but still no luck. I haven't tried downloading a new driver, because I can't with the current internet.

However - This is a problem while connected with ethernet and wireless. So maybe it isn't a driver issue?

Anyway, it sounds really ridiculous, but I can't actually upload an image, and even copy/paste my ipconfig, because my internet somehow doesn't allow it. So I'd have to go down to the uni, but since it's the weekend, I have no intent of going there. My internet is really killing me like that!

Try downloading the driver from another computer and copy onto a USB stick or burn to cd and transfer to your computer and install the driver.

I tried running the 6to4 and I am getting an error message telling me devcon.exe "is valid but for a machine type other than the current machine"

then "this version of devcon.exe is not compatible with the version of windows check 32/64 blah blah"

I am running the 64 bit version and my machine is 64 bit


is this normal? do I just carry on or stop it?

Lakenz when you connect at your university you don't use a proxy do you?

Just had that thought?

So did you disable the Msoft WIFI miniport?

TheCyberMan - Yes, I connect to the internet via a proxy at the uni.
+ I think I will download the drivers there on Monday.

chev65 - I disabled one called Microsoft Virtual WiFi Miniport Adapter. But I left the WAN Miniport PPPOE, as that is what I need to connect to the internet here.

At the hostel it sounds as though it is looking for the proxy server.

Please check in control panel>Internet options>Connections>Lan settings there is a checkmark in Use a proxy server for your Lan make a note of address or hostname and port number.

Is there a checkmark for bypass proxy server for local addresses and under advanced please make a note of any addresses in there and where they are.

Once done at the hostel remove the checkmark from Use a proxy server from your Lan and place a checkmark in automatically detect settings click ok.

Re-boot the computer and check for internet connectivity.

If you use firefox browser and it is set to use a proxy you will need to set it to no proxy but make a note of addresses and settings before doing so.

I'm sorry at how tedious this is!

Okay, so I went and checked out the LAN settings, but like I thought, it was set on "Automatically Detect Settings".

Note: It connects to the internet at my hostel, just not to facebook and windows live(sites like that). I have to clear the browser data, then I can check Facebook for about 2 pages, then it stops loading again.


Thanks again!
