Windows 7 wifi connected, but no internet connection

[dellic sekunde]

Hello all, I found similar topics but not solution for mine, please help.

I connect to my home wifi and it says connected, but there is no internet connection.
I noticed that network adapter shows "wireless network connection 2" with that "2" at the end of name. I guess there is a problem. If I rename it to just "wireless network connection" it says it already exists. But cannot see it, and use it! Can anyone tell me how to reset it or somehow switch to "wireless network connection" without "2"?

Also when I type ipconfig/all I get this:

[Trouble]

Hello and welcome to the forum. Give this a try first and see if your problem can be resolved using this method;
Evidently the driver (new versions) default to setting the "BSS Mode" to 802.11n and some have found that changing that setting to 802.11g has resolved their issues. So....
Go back into device manager
expand network adapters
select then right click the problem wireless adapter and choose properties
select the "Advanced" tab at the top
In the left column titled "Property:" see if you have a BSS Mode listed. If so select it and in the right column titled "Value:" use the drop down arrow to change from 802.11n to 802.11g
OK your way back out of there and reboot and see if that helps.
Regards
Randy.
