In Windows 7, I have a WiFi network that shows up with a warning icon overlay and the "No internet access" description as shown in this image:

No Internet Access

The other network shown there is a VirtualBox VM, and is expected to show that way.

Plainly, this notice is wrong as I have been browsing with that connection all afternoon and used it to post this question.

What makes this message come up, and how can I make it go away?

I think I figured this out. In the "Internet Options" control panel applet there's a "Lan Settings" dialog with a "Autodetect proxy settings" checkbox. Unchecking that seems to have helped things.

Update A much better explanation of what is going on can be seen here:

I have the same problem at home, but on a wired network, I get the red cross saying no network - even though the connection works fine with internet and local network. I will try your answer when I get home and report back! – falter Apr 14 '10 at 9:05
I can confirm that this did not work for me :-( – falter Apr 19 '10 at 10:18

i have also faced this problem(no internet access) many times on windows7 and i tried lot to remove this problem but problem still remained as it was. ......................but the one thing that i have noticed is that this problem occurs only with the systems with preinstalled windows7.So if you install the fresh copy of windows7 then this problem will not come again.

.......So from my point of view install the fresh copy of windows7 on your system, this will definetly remove your problem.

thats all
