Windows 7: Cannot Connect to Internet or Network (sometimes)

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.

From your ipconfig it looks like you have DHCP turned off for some reason, and that your DNS servers also aren't showing up.

Are you using a static IP for some reason?

If so did you enter all the required information into the IPv4 properties?

Have you tried to enable DHCP and see if the connection works any better?

You should be using the driver file I attached here for Windows 7.

The security and encryption should be WPA2 and AES encryption for this card.
You will also get the best possible wireless speed using the 802.11n Only setting.

I don't want to upset you but the problem lies with the cheap card. I also tried that same one and it always had problems for me no matter what I used it in. I went and got the Newegg.com - Rosewill RNX-N1 Wireless-N 2.0 Dongle (2T2R) IEEE 802.11b/g/n USB2.0 Up to 300Mbps Data Rates/ WPA/WPA2 (AES, 64,128-WEP with shared-key authentication) Cisco CCS V1.0, V2.0 and V3.0 compliant Vista/Wi and I never had an issue again. This small USB device loaded everything from windows and connected immediately. I tried it on some other PC's and laptops with perfect results.

@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.

I did change it back to auto, which is why I responded with it is not static (anymore). Still no progress. I looked at my router and it doesn't even transmit in 802.11n. Just 802.11b and 802.11g.

I had tried at one time to enter the IPv4 manually, but it didn't work. So I changed it back.

I looked at the reviews of the wifi card I have, and some of the bad reviews sound like what I have. They describe being able to see the router with good signal but can't connect, or get disconnected frequently.

EDIT: Here are the current settings as of right now.

I don't know if it helps, but this is the router I have.

The screenshot was immediately after I tried to connect, which was unsuccessful.
