|I've had much success here in getting solutions to my pc problems in the past, and hope to get the same result this time. I recently had broadband activated at my home, and set up a LAN, but I am already having a problem I can't solve on my own. First, the necessary info: my DSL connection is coming through a home gateway (modem/wireless router), with which I have set up a LAN. I connect to the LAN (and therefore the internet) with a single, notebook computer, though sometimes I use an ethernet cable, and other times a wireless network card (depending on whether I want to sit at my desk or on my couch!). |
Here's the problem: whenever the computer's connection to the LAN is interrupted (whether by disconnecting the card/cable, or by putting the system in standby or hibernate), I cannot subsequently re-establish the computer's connection to the internet: Outlook will not retrieve or send mail, and the browser will not load pages. What's more, whenever this happens, I cannot even access the control panel for my router, leading me to conclude that the computer is failing to even connect to the LAN itself.
As expected, when I'm trying to re-establish the connection via wireless network card, the computer fails to acquire a network address. However, paradoxically, when I'm using the ethernet cable, the icon in the system tray shows that there is a LAN connection present and that it is connected at full (100 Mbps) speed, and the Local Network light on my router turns green.
The only solution to the problem is to restart the computer WITH either the network card or ethernet cable plugged in. When I do this, I have no problems with my connection until I standby/hibernate, or disconnect the card/cable.
The only thing that I have tried to fix the situation so far is assigning a specific IP and DNS to the computer's connection. This did not help. I've since restored the automatic assigning feature.
I'd appreciate any help that anyone can provide, especially suggestions of what might be causing this problem, and what might be done to fix it.
