Windows – Issues with internet after sleep mode

connectioninternetsleepwindowswindows 7

i have a weird issue that started happening a few days ago, for no reason (no new software was installed or windows update was done when it happened the first time).

Just like most people, i rarely shut down my pc, i just put it to sleep till i need it.
My problem is that lately, my internet connection has been practically useless when i wake it up, i'm forced to restart the computer if i want to be able to use internet without issues.

When it wakes, it reconnects to the router without problems, it says there's internet but browsers, steam, etc cannot connect to the internet, i can't even ping the websites from the cmd but weirdly enough, skype sometimes still works when that happens.
I can't even access the admin web page of the router i'm connected to (the 192.168 something)…
I dont think it is the router since its only this pc that has this issue (other devices work fine), plus i've hard reset it and i still had that issue when the router was again up and my pc connected to it.

Also, reconnecting or even removing and plugging in the wifi adapter again doesn't do anything, it connects to the router, says theres internet but i still have that issue.

Even stranger is, if i wait long enough ( 5-10 minutes), it magically starts working fine and i can access websites and do stuff normally, sadly its not permanent and only lasts for a couple dozen minutes before starting acting weird again, the process then repeats (works, stops working…).

Its really annoying because its such a weird issue and the only solution i have for now is to shutdown the pc instead of putting it to sleep.

Any tips?

Thanks

I Turned the power setting OFF (i.e. UNCHECKED the "turn off the device to save power" setting) and it is now working fine.

To answer Scott's comment and anyone looking for this setting, this is how to reach it:

Device Manager
Network adapters
Double-click the adapter pertaining to the network connection of interest
Click the Power Management Tab
UNCHECK "Allow the computer to turn off this device to save power"

This is the same answer Brian gave the next day. I am performing some tests to see if it speeds up reconnection to the Internet after waking up from sleep.

Networking – Internet issues with subnet mask/DNS

As Jim G said, a router typically forwards lookups to the IP of the DNS server it is configured for - To add... The benefit of this is that devices can register themselves in DNS so you can access via hostname - this would not work if you only used your ISP's DNS (excluding Netbios/similar).

As for the netmask... networking 101 time!

a netmask literally masks everything before it... For example,

255.255.255.0 can be:

XXX.XXX.XXX.YYY

In the same way as:

255.255.0.0 can be:

xxx.xxx.YYY.YYY

What I mean by this is, the subnet just defines what is on your own network, anything that isn't, requires you to go through the router. By using the range 192.168.1.x on a /24 (255.255.255.0) subnet, simply means that anything from 192.168.1.1-192.168.1.254 is on YOUR network, anything else has to go through the gateway.

By changing the subnet to a /16 or 255.255.0.0 simply means that your network is 192.168.0.0 - 192.168.254.254, but, as these are all private addresses, it really shouldn't make that much difference in a home network.

As to why it suddenly changed, and the fact you are using a bridge, all I can think is that it was either an update to the router/similar that caused problems, or a driver update on your machine.... but, it is an odd one.

Internet Connection – Issues After Installing Windows Phone 8 SDK

Disable the virtual connection:
Control Panel -> Network and sharing -> left side open change adapter settings.

Right click on the virtual connection and select disable, and then enable your 'real' connection and see how this goes.

As per your comments, you are able to do this but after reboot, after a few minutes, the problem persist and connection is lost (although the V-ethernet remains disabled).

Since there is no difference between your "ping" of both your local router and 8.8.8.8 (eg ping 8.8.8.8) it confirms it is your machine.

Update

I would now open start, type in msconfig and in the start up menu, look for anything which is called vEthernet and disable it.

I would also open start, type in task s (to load task scheduler) and ensure there is nothing in here about the vEtherent.

Lastly, I would open start, type in services.msc and check here - it could be in there as a delayed start (this may be hard to find!)!

If there is no luck with the above, try a system restore.

Update 2

On the host computer, open Internet Options from the Control Panel. The Internet Properties dialog box opens.

In the Internet Properties dialog box, click the Connections tab.

On the Connections page, click the LAN settings button. The Local Area Network (LAN) Settings dialog box opens.

In the Local Area Network (LAN) Settings dialog box, deselect all the check boxes. Click OK twice to close both dialog boxes.

Restart the emulator and retry the connection.
