I have this network issue with windows7 on a laptop, the connection suddenly drops, sometime at laptop->modem, sometime at modem->isp, sometime both. The ADSL modem is on autodial and become DHCP server, should be plug and use for pc.
I believe this is not modem/router problem, but with windows7 itself. Reason is the modem settings is never touched, the win7 is new pc however.
My previous winxp pc have no such problem, connection lasts almost forever/weeks without unknown connection drop.
I also notice, win7 sometime did not detect the net cable plugged in, even if i tried it multiple times/disable/diagnose. Resetting the router/modem or reboot win7 and it will. Manual IP also doesnt solve the problem. Laptop has been open once for display replacement, could this have effect on net card ? If so, how come i still able to browse ?
Is there someway to solve this ?
I understand what youre trying to ask. Its a bit complicated here since the router->isp too sometime affected, which I found a bit weird.
The answer to your question : The connection is totally drop, its like you pull out the cable.
Add: I just check the modem log, and found this.. 7/16/2010 8:28:21> LLC 1483 unknow protocol
IMHO If firmware/driver is outdated, it still wont affect connection. On network protocol level, everything is disabled/removed except IPv4 only. Is there a new IPv4 protocol stack ? LOL Aww there it goes again. The LAN is ok but ADSL dropped. sucks. – afifio – 2010-07-22T04:04:56.713
