I would personally leave your machine default ( with tweaks in windows ) from the start. After installing each application or addon I would reboot and try them out for a day and see where the offending application is. Just by looking at your screenies it looks ( bad assumption ) like you have a ton of STUFF installed on your machine. If that is what you like then fine, but if you want it to work I might tone it down a bit until it gets outta beta and more applications are readily available for windows 7. Something is obviously causing the issue with internet connection. Maybe you have not done all the updates.. Maybe the NIC is being seen and loading a driver that is incompatible. Maybe you have a virus that has lingered since the first install and is shutting down the network connection. Lots of possibilities.. who knows.. Rootkit virus? For you to have installed 5 new times and keep having the same problem, I would install windows 7 once more.. Then each time you install something new no matter how small, reboot. See if you still have access. Something is causing the issue and it is either something you are installing or a hardware problem. ( guessing ).
u r guessing wrong , i have done the updates everything is normal besides the problem i'm telling, i'm interested in testing the beta n as far as i know the idea of the beta is of installing all the applications u use everyday n report back to microsoft which ones r incompatible, as far as i know the idea of the beta is to find the problems that it has n contribute pointing them out , so when it is finally released it can work great, if ur idea of a beta tester is dnt install anything ....
what u say that i have a virus , no i dnt have one and i'm not the only one having this kind of problem

i think is something related to the fingerprint ,i'm not sure , i did it everytime i installed a
new application test if it worked for some time, i know the problem is not something i have installed
cuz my wife is testing windows 7 too , i installed it in her laptop n she has almost the same
programs i have on mine n in her laptop she has had no problems.
i dnt have plans of formating anymore, i only want to hear from ppl that is having the same problem
n have found a solution or is searching for a solution, may b we can check what we have in common
n find out what is causing it
