Thank you,

I've seen that after owners update drivers. I don't have a good cure but to head back to the stock drivers.

Is your router plugged into the same power strip?
by Gordon_Hay / May 3, 2013 7:07 PM PDT

I have been having a similar problem when I take my Toshiba laptop back to its usual place near my Virgin supplied Netgear hub and switch on the power supply to the laptop, which is on the same power strip as the hub. It has also happened once or twice when resuming from sleep.

I went through all the usual checks on drivers, troubleshooters etc without success, before stumbling upon what appears to be the answer - it is simply the act of drawing power to the laptop that is causing the internet connection to drop out, and it usually requires rebooting the hub a couple of times to get it back. When I move the computer back there but continue on battery power the connection stays on, then when I plug in and switch it on the connection usually, but not always goes.

If I power the laptop from a different outlet or in another room there is no problem.

router plugged in
by tedtks / May 4, 2013 4:58 AM PDT

interesting idea - I have a similar poblem but figure its due to other factors. if I start the desktop with the new printer plugged in (hp 6700 - connected to usb port) the system will lock up. so I dont plug in the usb line
until its powered up and I actually need it ... then all is good. probably an hp thing with its drivers immediatly
wanting to check in home to update hahaha which I have turned off, but it still tries to connect - I think.
I will stew on this for a while to see if I can deduce anything on it. (dropped connection)

Power saving and/or IP Conflict...

Have you checked your power saving settings to make sure that it is not set to allow your computer to put your network card (wired or wireless) to sleep or shut it down?

It sounds to me, first impression, that your computer(s) may be putting your network device to sleep or turning it off until it is required again which may or may not be working correctly, a lot of people experience difficulties with this type of feature.

It is also possible that when waking back up your computer is simply attempt to pick up where it left off with the same IP assignment from the router and your router no longer recognizes your computer as an authorized connection at that address.

Hope this helps

A single, stray strand of wire.
by Gordon_Hay / August 3, 2013 2:21 AM PDT

In case you are still watching this thread, and for anyone coming here with a similar problem, I thought I should post an update detailing the answer to my situation which I described elsewhere on the thread.

I thought I had cracked this a few times but these turned out to be false dawns, it was only when I noticed during one of these outages that the connection to my TV box was also out that investigations let to the fault being found in the cable feed into the house, specifically the connecting plug fitted to the end of the outdoor grade co-ax where it enters the house, where my ISP's technician found a single strand of wire coiled around the "stinger", the central pin in the plug.

The person who installed this plug evidently failed to notice this strand coming from the braided shield of the cable and trapped it in the plug, which then wrapped it around the pin as it was screwed into the socket, introducing "noise" to the signal. The technician teased this wire out, replaced the plug and all has been well since - he said that while uncommon, this is not an unknown fault.

Now, I don't pretend to understand how this "noise" combined with the change to my laptop's power state - mostly from battery to AC power/charging, occasionally charging to fully charged - triggered these outages but it did, and it has not happened once since the repair.

I hope this info will help anyone else enduring this annoying and persistent fault.
