Windows 7: Sony Vaio Laptop "stopped" connecting to WiFi connection " Limited acc

Hi,
I am hoping you can help me with my problem.
My main laptop (Sony Vaio VPCCB15FG) in the last week just stopped accessing the internet via WiFi.
It says it has Limited Acess but I have no idea how to fix it.

The other 3 computers in the house (Custom desktop, Toshiba Net book, Samsung Laptop) can all access the internet as normal.



It is only the Sony that is being problomatic.
It is also running rather slow for the spec so that may be related.

Please help! I am not super computer savy so please give simple instructions.

Cheers

Hi Riyaz,
Really appreciate your offer of help.

Laptop is an i5 2410 with 4gb ram
OS is Win 7 x64 Home edition

Device manager - Network Adapters has the following items listed
Atheros AR8151 PCI-E Gigabit Ethernet Controller
Atheros AR9285 Wireless Network Adapter
Microsoft Virtual WiFi Miniport Adapter #2

I hope this helps.

Cheers Neil

If you can go into your Device Manager then to Network adaptors, expand Network adaptors then disable the Microsoft Virtual WiFi Miniport Adaptor it should make your connection work again.

This Virtual adaptor has been causing many connection problems lately and usually just disabling it will get the connection working again. This isn't something the guy from Dell would know about and I've fixed this same issue many times.

Let me know how it works out for you.

chev65, no hijack intended, but can you expand on your comment?
Why so many wireless adapters on a laptop? 4 0n mine.

Hi Chev65,

Just tried disabling the Microsift Virtual WiFi miniport and no luck. Restarted the Sony incase that helped and still no luck.....

ANy other idea's

Lets try resetting the IP and flushing the DNS, this will fix any problems related to the network stack so as to narrow down what the problem might be.

Save the file below, unzip and run the file, let it run until your machine reboots then check to see if you can get online.

Hi,

I ran the file but no noticeable change to my wifi connection.

Any idea where to next?

Cheers

If you can post a screen shot of your ipconfig/all it would be helpful.

Also if you can post a screen shot of the read out from Xirrus WiFi inspector it would also help.

Option #2 shows you how to obtain the ipconfig/all.
IP Address - Locate and Find for Your Computer

Wi-Fi Inspector | Xirrus

If you are using AVG you should uninstall it completely as it causes wireless connection problems, also if you have iTunes installed the Bonjour "service" would need to be uninstalled.
