Windows 7: Unable to connect to wireless networks

Unable to connect to wireless networks

Hi, I've had my laptop now for a couple of months, and have recently noticed that it struggles to connect to wireless networks. The problem is strange in that it will quite happily connect to, and stay connected to some networks (ie my BT Home Hub), but will completely fail to connect to others (BT Openzone). The problem shown with Openzone is one relating to DNS, saying it is unable to resolve the primary DNS server. I've included a file detailing the results of network diagnostics - I won't pretend to know what it all means, so hopefully someone on here can tell me!

BT Openzone is my primary source of internet, as the Home Hub I use is only when I go home to visit my family. I've been having to use a network cable to connect through my pc, which is inconvenient, and doesn't help me when I'm not at home.

Also, I'm not sure, but the fact that my Microsoft Virtual Wifi Miniport Adapter is having problems (error coe 10 and will not start) may be something to do with it? I've tried updating drivers etc, but they won't install as the adapter itself cannot start.

Please help!

It could help by flushing your DNS Cache. What is your DNS provider. How to Flush DNS | Networking - Miscellaneous | Asked and Answered

I'm afraid I have no idea what my DNS provider is, I'm not an expert on these things, and am pretty helpless as far as DNS goes. I tried flushing my cache, and stopping and starting the DNS client, to no avail, but when I entered ipconfig/displaydns into the command prompt all I got was "could not display the DNS Resolver Cache".

Does this narrow things down at all?

I've just looked, and on my pc, it lists the IPv4 DNS Servers as three numbers, two of which are 192.168.22.23, the other is the same, but ending .22.

However, my laptop has two numbers, 8.26.56.26, and 156.154.70.22. The first one looks wrong to me, not sure what you think about it though?

Open start menu, type cmd press enter, in the box that opens type ipconfig /all there is a space between g + / look for your dns servers as in my image.

Seems a bit strange to me, that each Ip states I'm in the us, when I'm actually in the UK. Also, each one is a different state. Surely that can't be right?

As for my router, I don't have one. I'm connecting directly to BT Openzone, which is provided in the building where I live. I have no control over it, cannot reset the hardware or anything. All I can affect is my pc.

The above are the locations of the dns providers, so don't worry about them.
I suggest installing CCleaner follow my image on how to install it. Once done, open CCleaner, click on he 'Registry' tab and Scan for issues, fix all. Then click the 'Cleaner' tab, tick the box to add DNS Cache, Analyse and run. CCleaner is totally safe to use.
