Windows 7 network Slows down Packets are Lost
Posted on 2009-12-20
1-No router, directly plugged into the cable modem
Two identical HP tablet 2730p tablet laptops one with Windows 7 and the other with Windows XP. The one with Windows 7 will begin to have intermittent connection after xx minutes. If I do a restart, I can ping sites with no packet loss and surf the web with no issues. But after 10-15 minutes, internet pages will error with page cannot be displayed and I will get 50-75% packet loss on pings. I have to keep refreshing to page over-over for it to pull in. If I disconnect the cable from the PC for xx minutes and reconnect all the speed comes back until xx-minutes and I am in the same boat.
If I do the same with the WInXP laptop no issues no packet loss. Surf the web does not present an issue at all
The Windows 7 network slow down happens on wireless as well but to eliminate devices I am doing this directly from my cable modem. No forget the wireless for now.
Wi-Fi is off on both units
Test by not using the PC's network devices
Job provides me a cellular card. Again when I insert the card in the WInXP machine no issues at all. When I place the card in the Win7 machine I get great connection at first with no packet loss, but after xx minutes I began to see packet loss on this card and surf the web with began showing page cannot be displayed
This is driving me crazy...what is it about Win7 and it's network. When do a ipconfig /all the ip address list some:
IPv4 address: 184.108.40.206(Preferred)
ipconfig /release all does not seem to break the IP lease that is set to expire on 12/24/09 and looks nothing like XP how it list the address. The IP is different from machine to machine meaning if I take the cable out the XP machine over to the Win7 identical machine.
I have unplugged the router on each machine reboot and keep getting this crazy issue. Help
