Unhappy Can connect wireless, not wired
Hi guys,

Been reading the forums here, found some related issues, but not able to hit the nail.
Hope someone can help me out!

Here goes:
I have 1 PC, 1 Vaio laptop, 1 PS3 in the room.
Netgear wireless router has been giving me good access to all of them & the internet.

Till recently, the laptop was not being used, so was not connected.
My partner decided to use it, thats when this problem started.

The PC had a wired connection, the PS3 wireless.
There were no problems in connecting to the net through either devices, or for streaming movies onto the ps3 using media servers on the PC.

I recently decided to connect this laptop as well & then things went wrong.
The laptop & the PS3 which are wireless connect easily to the network & can browse the net.

However, on the PC there is no joy.
Sometimes when i reset the router & restart the PC, i can connect and use the net with no issues.
But this is temporary.
i have not been able to pinpoint how long this lasts or when it connects & disconnects. i believe there are no regular intervals, just random.

I am even unable to recognize the media servers on my PC via the PS3, though at the same time i can view media servers on the laptop. Basically the computer is dead to the network, can not connect to the internet or be visible to other devices in the network.

i would also like to add that when we decided to use the laptop, to make things easier i installed teamviewer to remotely access the PC through the laptop... blame it on my laziness. Not sure if this could be the reason for the problem as i installed teamviewer almost immediately after connecting the laptop.

I really have almost zero knowledge in networking , so please be easy on me

Welcome to TSG:
Let's see this from the pc when not working
Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)



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

Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

And did you uninstall or disable teamviewer just to eliminate it as a potential culprit ?

Try the following repairs. If you still get that "Default Gateway . . . . . . . . . : 0.0.0.0" then reset the router to factory default settings and reconfigure it.

(From a JohnWill post)

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

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

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.

Hi Guys... Sorry for the late response, was out of town for the weekend.

Well, there is an update.

I decided to try pedroguy's suggestion first to uninstall teamviewer & voila! the system is back to normal.
I have used the internet for varying time durations and there has been no problem at all.

So iguess that was causing the error.

Is there any way to know if this is an existent problem with the program itself or a one off?
How do i know this was infact the problem & will not occur again? should i b ecopy pasting the cmd->ipconfig details to confirm.

Thanks a bunch

If you re-install the program:
And you have the problem again,then you will know for sure.
If you install the program and you do not have the problem.2 possibilities.
It was not the program,or re-installing the program fixed some corruption or program problem.
I would like to see another ipconfig /all just to compare it to the first ipconfig /all

Oh well.. Back home now... Just to see that the net is NOT working on the PC, but IS on the laptop.
I don't quite understand what the problem is cos the last 2 days there did not seem to be a problem...

Here is the ipconfig /all after the uninstall of teamviewer.
Not sure if anything is changed.. Let me know

Assuming that is what we were intending to do?

Yeah guess so. However, the last time (after i uninstalled Teamviewer), the net worked perfectly well for 2 days.
But eventually died... i hope this is the case now.

I would however like to know, what caused this problem (assuming for a moment it had nothing to do with teamviewer).
Is there anything i should do to ensure it doesn't repeat?

Thanks for all your help so far!

I strongly doubt the "Default Gateway . . . . . . . . . : 0.0.0.0" was caused by Teamviewer (but stranger things have happened). I suspect it was a corrupted stack (hence the repairs worked) or it is an intermittently defective router.

I noticed the problem after installation of teamviewer.
I had chosen installation of VPN during first of teamviewer.
There was a new addition to the network devices in device manager which stated VPN (or something of that sort).

Now since teamviewer has been uninstalled, it has been removed from the list.

I maybe wrong, but i feel the problem was caused by this aspect of the program & not teamviewer on its own completely.

There doesn't seem to be any problem now. However i am going to try re-installing teamviewer again & see if the problem arises.

Thanks for your solution TerryNet
