Hello, I here recently have been having problems with my wireless connection at my school.

A couple specs, SONY VAIO - VPC-EB11FM. The computer has run problem free for the couple years I've had it.


About a week ago, I dropped a little bit of water on the mouse pad, and the left clicker, and wireless went out. I cleaned the water off, then rebooted it. and everything was fine. A WEEK LATER...

I'm at school now, and I am having problems staying connected to the wireless, i even have tried using an ethernet cord. My roommate stays connected always, no problems.

So, I've tried to narrow down the problems, and it seems when i get on in the morning, and my computer is cold, It works fine for awhile, I play a game called League of Legends, and after I play for an hour or two, and my computer is heated up I start to lose connection, or it goes in and out and wont stay connected.

So I KNOW its not the schools internet, as I've stated, my roommate is connected just fine when im having problems. Dying to fix this :( Many thanks to any support. If this is fixed with low-to no cost, I'd be glad to give a contribution to the site.

so you disconnect both with a cable connection and a wireless connection and this only occurred after dropping water on the touchpad.

What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG , Webroot etc

would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
Make sure you also indicate on the reply which tests are for what condition.

lets see the following please

ipconfig /all
Three Ping tests

------------------------------------------------------------------------
ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply
Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the infomation above those entries

We would like to see the results from an ipconfig /all - post back the results in a reply here.

This should also work for windows 8
Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results into notepad and then automatically open the notepad and display on your screen.

Now all you need to do is copy and paste those results into a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will now be highlighted
Next
From the notepad menu - choose Edit - Copy

Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
The results from the notepad should now appear in the forum reply.

Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

For Windows 8
to open a Cmd Prompt or an Administrator Cmd prompt from the Desktop. Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.

Type the following command
Ping {then a space and then add the number that is shown against the item labelled "default gateway" shown in the results from the ipconfig /all}
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Type the following command
Ping google.com
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and

Type the following command
Ping 209.183.226.152
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste
For your information only
these tests will check various stages of the connection, the first ping test, ping default gateway checks to see if you still have a connection to the router.
The next two Ping google.com & Ping 209.183.226.152 tests the connection to internet. google is to test by name and the ping test using a number is checking that a connection exists without DNS.
these tests then confirm if there is a dns issue on the connection.

RESPONSE to anti-virus programs...

I currently have Malwarebytes installed, and use that and have found NO infected files through any drivers. I believe I have used AVG sometime ago, and Our school currently offers Mcafee for free , but i dont have it yet. But I have done full searches


ALSO FIREWALL:

I have seen a few places , that it could of been my firewall interfering , but i would need further direction on that to know if i have wrong settings. But i dont see why my wireless would work sometimes then not work. if the firewall had anything to do with it

Every day firewalls invent new ways to intermittently fail and frustrate the heck out of us. :D

About a week ago, I dropped a little bit of water on the mouse pad, and the left clicker, and wireless went out.
Is your wireless card in that area?

Yes,My wireless on and off switch is right below my left click on the touchpad. And the water went on the left click directly.


BTW: Right now im connected, problem free, and any minute its going to just lose connection again, and it will tell me "Limited access" & "No internet acess" but will be connected, with a yellow triangle with exclamation mark.

Run the AVG Remover.

If this is caused by a firewall (or other security application) it is not because of settings it is because of corruption, and it will need to be uninstalled and the Removal Tool (if one exists) run.

For this post I am going to ignore the possible (probable in my mind) physical damage.

I'm not clear on all the symptoms. Does ethernet have the same on/off trouble or are you not able to connect to it at all? Why does the ethernet not show above in your ipconfig /all?

When the problem occurs do you you still have a valid IP configuration as above? Can you ping your own IPv4 address? Ping the Default Gateway? (Wayne already asked for this info by asking for the ipconfig /all and pings when the problem occurs; I am assuming that your above results were for a good connection.)

Make sure you have the latest wireless driver from your laptop manufacturer's web site. Reinstall it if you already have that one.

TCP/IP stack repair options for use with Vista and 7 and 8.

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt. [For Windows 8: <Windows Logo> + x - Command Prompt(Admin)]

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

I don&#8217;t know how to get the the IPv4, its not pulling up on cmd when I do ping IPv4. But I also don&#8217;t know how to get the internet to run just via Ethernet cord, I always have it plugged in, but it seems to just auto do wireless.

ALSO- I have checked for latest driver update. (see notes, for possible other useable driver "SmartWi" from sony. (It says on site it is compatible with my computer model.

OK, so now from that latest ipconfig /all we know that when you lose connection the adapter still shows up but it has indeed lost the connection (no longer has an IP, Default Gateway, etc., from the router).

It would also be good to see the following for both a good connection and again for when the connection has dropped ...

Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 8 or 7 or Vista I prefer to use the built-in Snipping Tool.

I think the adapter or the part of the motherboard to which it connects is defective, or possibly a problem with the antenna leads or connection.

How would i further my investigation, and try to narrow down what it may be?

If the wireless card is easily accessible through a cover on the laptop bottom remove and carefully and firmly replace it several times. Make sure the antenna leads are secure. That's as far as I know to go with something like this.
