Windows 7: Connected to wireless but can't access the internet

Question; when you left click your network icon in the notification area, does it show your friends network? If it does, when you click on that network, does it say connected or connect? When you hover the mouse over your friends network does it show the security type....wep, wpa or wpa2-psk. Or does it say unsecured? If it's security protected, do you have the network user name (SSID) and password to log on with?

Yes, ofcourse.
I have password, and it says "Connected", as you may see below.

Here are informations which gives program of my adapter:

Ok, I thought you might be at your friend's house. I see now that your friend allows you to access their wireless network. It's nice to have friends that share - mine do too.

Try this: reconfigure your wireless connection with static values.

O Use the following IP address:
IP address: 192.168.0.47
Subnet: 255.255.255.0
Gateway: 192.168.0.1

If this doesn't give you access to the Internet, you'll have to ask your friend to help you. There are too many settings on a router to try and test each one on a forum.

Someone else might be able to figure it out, but that's about all I can think of.

Good luck and take your friend out for dinner every once in a while

Alright, I'll see what I can do, because right now I have to go.
I'll post later results.
Thanks for help, once more.

Here's the manual (PDF) for the router you said you're trying to connect to.

There is something about your friend's router that doesn't seem correct. The manual confirms what I thought re: subnet mask and yet the autoconfig shows that your get 255.255.0.0 - so there's some work to be done.

See if you can match the manual configuration to your friend's router configuration. Make a note of the differences and discuss it with your friend.

From what you are saying it sounds like part of the network stack is messed up, possibly TCP/ip or winsock is corrupted which is fairly common.

Winsock entries tells Windows 7 how to access your network services. Additionally, your TCP/IP protocol can be corrupted. The TCP/IP protocol is a stack of 4 layers that includes several transport layers, but when this stack is corrupt you will constantly have connectivity issues.

If you can please run the following two commands one at a time, type them into an elevated command prompt and hit enter after each one then reboot your machine and test to see if you can get to a web page.

netsh winsock reset catalog (reset winsock entries)

netsh int ip reset reset.log hit (reset TCP/IP stack)

@kute: Chev65 gives a great suggestion - try that first before using the static IP address I provided.

I wish I knew as much about the TCP/IP stack on Windows as you do Rob - Thanks.

Thanks for reply chev65.
So, if I well understand you, I should open two command promts and then run first
netsh winsock reset catalog
then in a second command promt run
netsh int ip reset reset.log hit
and then restart?
OR
In one cmd, write/enter first line u wrote then in a new line write/enter second line, and restart?
Also should I be connected on this wireless network, while I'm doing this commands?

the command prompt must be elevated - right click to run as administrator
you can run them in the same command prompt
run them in the order Chev65 provided
No, you don't need to and should not be connected to the wireless
Sorry for jumping back in, saw this and replied to kute - Back to you Rob

I did this with commands and no changes.
I tried after using this commands, to do what you said with those IP-s, same happens, seem like IP/Subnet mask isn't correct or something, prob what you said, he changed configuration to the router.
Guys, thanks for attempting, I guess there are no any other chances left to try something more.
Best regards!
