Cannot Connect to Internet or Network (sometimes)

I recently built a desktop computer with a friend and we installed Windows 7 Home Premium 64-bit. After doing so I went out and bought this wifi card.

Currently, my desktop cannot connect to my network, but it has occasionally (I would say 10% of the time.) And when I do connect to the network I get "Unidentified Network, No Internet Access."

I've tried to remedy the problem myself by searching online using my laptop, which connects with no issues. I've seen problems that look just like mine but can't fix it. I don't have security software currently, so there should be a conflict there. I've tried restarting my router (absolutely no change), and I've tried disabling and enabling the network card, seen above.

I've attached a screenshot of all the info I thought might be useful. I've also attached the troubleshooting report I usually get when i can't connect to my network.

The farthest I got was yesterday. I was connected to the internet for about an hour, maybe more, and was able to install some of my usual software like iTunes, Skype, and the likes. Haven't been connected since.

I did have the networking software for the wifi card installed, but have uninstalled it since. I can still see that my router is within range and I have 4-5 bars of signal usually.

And here is my "ipconfig /all" when I am connected.

I hope I was able to provide enough information to solve the problem. If you have a question regarding the computer I'll do my best to supply the info.

If you installed iTunes there is a network service that installs with it called "Bonjour" which is famous for creating network problems in Windows 7.

You should disable the Bonjour in Windows services, you will see it on the list in services. You can get there by typing services.msc into the run box. You may need to restart after disabling the Bonjour service. iTunes will still work after disabling Bonjour.

You should also disable the Microsoft virtual WiFi miniport adaptor which you see in Device Manager as it also is becoming famous for creating network problems. The mini port adaptor is only used for creating a shared wireless connection.

Let me know is this has any effect on your network connection. :)

No luck with that.

@Chev

The problem with that is I live with my parents and sister. And if I'm not mistaken, I would have to change settings on the router for that. And I don't believe all our devices are 802.11n compatible. I'd rather not piss off my family just so I can have internet on one computer.

@Mike

If you really think that is the problem, do you know of a good card that I could put inside the computer? I would prefer not to have a usb wifi card sticking out the back if I can.

I just mentioned the wireless n setting gives the best possible speeds.

You didn't even answer most of the questions I asked which were all relevant.

If you expect anything to change then you need to be able to make changes.

Unfortunately there is no such thing as a magic fix everything button in Windows.

I also checked the reviews on this card and they aren't so good, seems to work for some with Windows 7 and not for others though I suspect the problem is with the set up procedure rather than card itself.

Oops, sorry. I had answered them but the token had timed out. So to answer questions, IP is not static, DHCP should be enabled, and I don't have antivirus software. And yes I realize there is no magic fix button, although it would be nice if there was so I wouldn't have this hassle.

Yes I agree on the magic button although Widows does have a self diagnoses feature it hardly ever tells you exactly what the problem is.

For some reason it's showing that you have DHCP disabled and the DNS servers aren't showing up in your IPv4 properties. It also looks like you are using wireless g rather than wireless n because of the 54Mbps speed on your adaptor.

Have you tried looking in your IPv4 properties to see what the settings are?

The signal strength looks good but it looks like your IPv4 properties for this adaptor isn't set correctly. It would be best if you changed it back to using DHCP for now.
