My laptop goes offline, but others in same office don't
Posted on 2013-01-05
hi- every now and again, my laptop stops accessing the internet. My husband is on the same router and it never happens to him. I'm using an ethernet cord and he is wireless. If I connect wirelessly, I still can't get to the internet.
Rebooting my laptop doesn't work. I tried to do a ipconfig /renew, and that didn't work either, it says the media is disconnected. I replaced my ethernet cord and that didn't help.
The only thing that works is rebooting the modem.
Here's what I get from Ipconfig when the computer won't connect:

I have a Dell Inspiron N7010, with Windows 7 Home Premium, 64 bit. My Modem is Technicolor TG582n, fairly new since we had it replaced about two months ago. This only started happening after the modem was replaced. When the internet goes down, I can still connect to the modem.
Any idea why this might be happening? I have Mcafee, but could it be a virus?
Probably not related, but I also get an issue where my windows explorer stops operating. (not Internet Explorer, my taskbar freezes and I get an error message saying, "windows explorer is not responding.") I have to close it and start it again. This doesn't necessarily happen at the same time as the computer freeze-up, but I thought I would mention it.

my wife had similar issue
I got her a second machine
(laptop and PC)
it does not happen with the PC with PRO....
so the other thing I did was update drivers and chipset
seemed to help...somewhat not entirely
also showed her how to disable NIC and enable it
this solves the issue 75% of the time
we still have the issue at least once a week that requires modem reboot

it could be a virus ?
when you say when it happens you can connect with the modem see if you can ping the dns server by fqdn or ip address and post the result here its a good test for dns that a virus can interfere with as I have seen fake entries in the local resolver ipconfig /displaydns

Ok try this
ipconfig /all >c:\ipconfig.txt attach the file for my review.
Also the default gateway seems strange 192.168.1.254
Did you modify the new modem Today we call these devices Routers not modems.
Most routers come defined by default 191.168.1.1
Is your network adapter setup to use DHCP or is it a Static Ip address?
if ipconfig /renew fails you ae not finding a dhcp server
The router must be configured to run dhcp have you checked the router settings?
On the back of the router where your ethernet cable is pluggged into are the lights on?
Are the lights on on your network adapter in your computer?

all of the comments above are good for basic trbshooting
seems like you already did most of that
since it is only ur pc .....the network and network setting delivered by DHCP should be fine
as mentioned as long as u are getting a good IP via DHCP
then don't worry about basic networking
the issue is specifically related to ur PC ONLY right...?
then that is the one to spend ALL your time on
ps you can run other monitoring tools (some are already in Windows 7)
Performance and resource...
thats what I did and although not answering my questions completely
it seemed to point to the NIC or internet(modem)
I have a separate cable modem and a Wired/Wireless Router
although we 'lost internet' on the one PC the 'network' connections were still alive
thus my few attempts surrounded the PC
I probably could have updated the firmware on the modem...but did not bother
