Skype crashes WLAN, can't ping loopback.

Hi,

I have a problem with my network connection and I can't identify the reason behind all this.

Here are the details:

First of all, my Skype jams the home router. I tried a million times and it always happens, as unlikely as it sounds. Whenever I videocall sb all computers in the house lose connection and the damn thing has to be rebooted. When I reboot the modem/router, sometimes I get a popup saying "IP conflict, some other computer in your LAN network is using the same IP".

Secondly, when I try the command "ping loopback" in the cmd console, I get at best 50% of response, but it varies. Sometimes it's all lost, and sometimes just half of it. The same thing happens when I try to ping my own router-assigned IP. The internet connection status is fine and working, Browser loads webpages.

I checked with my housemates and none of them seem to be having similar problems.

I already tried releasing my IP and renewing it, but the problem didn't go away. Similarly, I uninstalled the wireless network adapter card and installed it again. Windows says drivers are up to date.

One last thing: the crash seems to be linked to the VPN cisco client that I installed recently. I removed it in the course of searching for a solution, but it didn't help...

Does somebody know what to do besides reinstalling the bloody windows?

Regards,

Jan.

First of all, my Skype jams the home router.

Click on my name above in my response and read my "how-to" guide on troubleshooting wireless issues. Go through the troubleshooting steps. If nothing fixes the issue, try another router and see if it happens with another router. If it doesn't, then replace your router.

Secondly, when I try the command "ping loopback" in the cmd console, I get at best 50% of response, but it varies. Sometimes it's all lost, and sometimes just half of it. The same thing happens when I try to ping my own router-assigned IP. The internet connection status is fine and working, Browser loads webpages.

These are two standard troubleshooting steps to ascertain if the issue is hardware or if it's the TCP/IP stack. I'd start by uninstalling then reinstalling the tcp/ip stack on your interface. If that doesn't fix the issue, you will likely need to replace your NIC.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

Thanks a lot for the response!!!

However, I've got one more question: Call me stupid, but, could you tell me how exactly do I uninstal the TCP/IP stack on Win7? I knew how to do it up to Win 2000, but now it's got apparently much more complicated...

Thanks!

J.
