Hibernation loses Internet connectivity!

Topic

New Reply

I’ve got a new modem/router (2Wire) from AT&T on a Dell Optiplex 360. The old one died in early December, but had no problem with connectivity to the Internet after coming out of Hibernation. It did have lousy wireless security, but never had any hackers that I know about. The new one has of course the best security as far as I can tell. But after hibernation, the tray icon says I am connected fine; so does network in the control panel. But my browser (Firefox) & email client (Thunderbird) & other indicators says “NOT CONNECTED!” I’ve so far contacted AT&T, but have not solved the problem. Does anyone have any suggestions?

Try this:
Enter Device manager.
Right click on your network adapter.
Select the “power management” tab
Uncheck; “Allow the computer to turn off this device to save power”

I think it would help if you do some basic troubleshooting (when it hasn’t reconnected) to figure out where the disconnect is:

Do you know how to ping? If not look it up via google.

Ping the router’s IP

Ping your ISP’s DNS server

Ping yahoo.com

Open a command window and at the prompt type:

ipconfig /release

and hit Enter

wait a few seconds and at the prompt type:

ipconfig /refresh

and hit Enter

and let us know what happens.

(I used to have this problem all the time with XP but Win 7 reconnects automatically for me every time.)

Thanks. I saved your suggestion off to try at a later date. I’ve got new memory chips. new MB & new hard disk coming, so my attention in the the meantime will be to save all data I can.

if you go into your router setup there should be a page for your wireless settings. the channel your router broadcasts on will be listed. it’s my understanding that interference on that channel (whichever it is) is what causes this particular problem. hope this helps. as i said, this was a problem for several months until channel was changed. did this about 5 weeks ago and have not had a problem since.

Question…The wireless is for guests in the house, while the computer which has the problem is strictly Ethernet cable connected! Does that make any difference???

Thanks for your reply. Someone else has suggested the same process a few days ago. At the time, I have done what you suggested, to no avail. From my observation while the machine is coming out of hibernation, before the “resuming windows”, I see a screen which looks like the entire machine has been powered off. Furthermore, this exact same machine came out of hibernate perfectly with a much older version of the 2Wire modem/router for about a year before it died in December 2010.

Had this problem with my westell router for several months. Finally found a post on a forum that I can’t remember that said to go into my router setup and change the channel the router broadcasts on, in my case went to channel 1. Haven’t had a problem since. Router is still set to sleep to save power. I also do not allow device to wake computer as it seems to me either option would defeat the purpose of sleep/hibernate. Hope this helps.

What does it mean “change the channel the router broadcasts on”

Good idea, but tried that, and it didn’t work!

I have discovered 2 more things: Sleep mode seems to cause the computer to shut down! Also, there’s some kind of hard disk error which may be the key to all!:confused:

:)I don’t know about sleep mode, but the Hibernation problem was solved by a complete reformat & install of all new Windows 7! Thanks for all of your suggestions! This was suggested by Dell. Should I close this thread & how do I do that?

Your reply should be sufficient. Too bad you had to reinstall but glad you got it working. Thanks for posting back.
