No network after sleep of laptop computer

• Windows 7 "no DNS (or no network) after sleep (wake up) sleep (or Hibernate).

  The purpose of this thread is to understand the expected behavior of the TCP in Windows 7 stack and the cards on the resume from sleep/hibernate - not - display the suggestions that have been posted in other threads.  I also wanted to gather some folklore on this subject in one place...

  It seems to be a group of people having this problem Windows 7 "no DNS (or no network) after sleep (wake up) sleep (or Hibernate)" without definitive duty (or with various) responds to what the issue is.

  Do some reading on this in various places, I see:

  -Suggestions to disable UPnP.  This should be largely irrelevant to the problem.

  -Reset the default router.  Generally, this should not be necessary.

  -Reinstall Windows 7 (ah yes, the panacea for all ills!).

  -Replace DHCP static IP address.  This should not be necessary (considered at best as a workaround).

  -If it solves the problem, it points the finger at DHCP feature / state on the curriculum vitae of sleep?

  -Disable the firewall.  This shouldn't be a problem (why would it).

  -If it is a question, it is likely to be isolated, rather than the majority of the cases.

  -VMWare (or similar) virtual networks.

  -This could be a problem for some people.  It would be useful for anyone who has a problem to confirm if they have VMWare or similar virtualization installed products (who can create virtual networks).

  -Disable the TCP (TCP sliding windows) tuning car.

  -It is possible that TCP auto tuning could be a problem for some people - but - unlikely, it would be a problem for people only on the recovery from sleep mode.  I think that anyone with questions about the TCP (TCP sliding windows) tuning car rather than questions on RESUME intermittent connectivity problems.

  -Some people report improved performance when turn it off this feature.   Report MSFT from 10 x to x 1000 in laboratory performance. conditions.  It's one you need to test yourself to see if it helps or otherwise.

  -NETSH INTERFACT TCP SET GLOBAL AUTOTUNING = OFF

  -NETSH INTERFACT TCP SET GLOBAL AUTOTUNING = NORMAL

  -It works on XP but not on Windows 7?

  -It is fairly widely commented that the TCP stack has been re-written/improved thanks to Vista and Windows 7.  It is not surprising, therefore that problems on Windows 7 that do not exist on Windows XP.  This does not necessarily imply that the Windows 7 stck is bug, just as not all software and peripheral food chain TCP are speaking the language of same/current (in the absence of a better technical description).

  -One wonders, therefore, are only optimizations issues additional tuning and unloading that have been made in the new stack TCP?   How this confrontation with the problems that occur only in the curriculum vitae of sleep/wake extended?

  -Some people recommended prevents the system from voltage of their cards during the standby/hibernation.  Does this means:

  -The card is not dynamic.

  -If the card is allowed to be turned off so there will be a lag between the state saved in Windows and the State represented (none) in the card when the system is out of his sleep (or Hibernate).

  -Perhaps, it's something that needs to be addressed in the functions of battery/sleep TCP in Windows 7 - How to handle/recover the situation when the NETWORK adapter is turned off?

  -If we put the system to sleep, we want to have power supplied to the maps or not (what are the implications)?

  -People have the same problem for the hibernation?

  -If there is a problem of State related to the cards, would be - why, in some cases of people solve the problem by disabling optimizations that involve some treatment being given cards instead of being carried out using the processors.  If it was kept in the processors, we have consistent state on the resume (as opposed to cards)?

  I think what I understand of MSFT is here:

  -What is the behavior designed in the stack revised to ensure a consistent state between the adapter, battery, previously obtained DNS, DHCP settings, etc., the curriculum vitae of sleep/wake extended.

  -Unlikely connections persist across sleep/hibernation - so are they remind/re-restored?

  -Windows 7 has more work to properly manage this for cards that - are - power off during sleep?

  -Is - it a requirement of MSFT at this time for an own CV, the card must stay lit?

  An exchange of views on how this is supposed to work for MSFT would be useful.  Then perhaps hundreds if not thousands of people facing this issue can understand why it happens and how they can solve.

  Thank you for spending time and energy on it. I had a frustrating to deal with this problem, but - finally, disable virtual network cards seems to have helped.

• Need for other computers on the network to access my laptop computer to run a program

  I installed a program on my computer that acts as a service and I now need to install the application on other computers on our network.  Other computers need point to my computer in order to run the program.  Even if I set the program to point to my ip address, it fails.  Do I need to add a player shared or mapped on each computer to see my computer?  I am new to this and I would appricate all the assistance.

  Thank you.

  You should check with the technical support of the mystery about its requirements for network program. Client/server different programs have different requirements. Certainly, you must assign your portable computer a static IP address. If the laptop is not always in the office or available, it is not really the choice the most suitable to host the game server a program. But presumably you know the better your situation and feel that the laptop will work. MS - MVP - Elephant Boy computers - don't panic!

• Peripheral USB malfunctioned after fashion "Eve" laptop computer in Vista

  If I turn off my cell during the night and then open it in the morning, it works very well for a while and then this happens. The sound begins to become an anachid. USB devices don't work. I can't connect the printer, a USB key or CDMA cell phone through which I connect to the internet. Even the bluetooth connection does not work. This works for two or three hours if he rested all night. If I let it sit for an hour in the afternoon, and then open the computer it works for only about half an hour or so when the problem is recurring.

  Either your laptop is overheating and/or your equipment is faulty when it's hot. Since it is a laptop, the question is on the motherboard. If the laptop is still under warranty, contact technical support of the portable mftr.. If this isn't the case, then you must decide whether to spend rather a lot of money on the replacement of the motherboard based on age and the initial cost of the laptop.

• Why not work network after sleep (pfsense VM) based on freeBSD?

  When you resume a computer virtual which has a guest operating system (a gateway and a firewall based on freeBSD), pfsense networking does not work.

  Even if the user interface shows correctly in place of the network interfaces. And the two network interfaces of the gateway that are connected, the WAN one like a usb device (usb-to-ethernet adapter physical network), the LAN as a network card virtual vmnet3 and other virtual machines that use this bridge across vmnet3 look good too.

  What else could be bad due to the recovery, it was well before the last suspended?

  Hello

  UH... Yes the internet USB adapter is indeed likely your culprit, not sure how I missed that in your original post.

  Unfortunately, there are a lot of people having trouble with the USB from one version to the other, and the way that it works is moving.

  Of course, the intention is to better support for USB, but VMware also regularly breaks things in this particular area.

  Back to a version might help.

  There are also a whole bunch of parameters vmx USB change their behavior... and they are mostly undocumented.

• After syncing firefox from one laptop computer to the other, I repeatedly get syncted phone has the same IP address as the original. Reverse?

  One of the results of these two laptops with the same IP address was that the original laptop computer proxy settings have been changed and I could not get into the internet. After you restore the default proxy settings, I again had access to the internet, but two laptops always have the same IP address.

  You do not use DHCP to automatically assign different IP addresses?

• I have 2 imacs and a laptop computer and you want to back up all three wireless via time capsule on my existing wifi network. If we can also use the time capsule as my wifi and replace my uverse wifi, that would be great. possible?

  I have 2 imacs and a laptop computer and you want to back up all three wireless via time capsule on my existing wifi network. If we can also use the time capsule as my wifi and replace my uverse wifi, that would be great. possible?

  If you want to make sure that you will be able to get the Apple support in case of problems or questions with your backups, you must use the wireless Time Capsule to back up your Mac.

  As long as the time Capsule provides a wireless signal, you can decide who to your 'main' network, then use it wireless Uverse for "guest", or children. If you do not need the Uverse router/modem wireless at all, it is possible to turn off wireless on the device and make it work only as a support modem/router...with Uverse wired.

  At this point, you can start thinking about how you want to configure things and get back in touch if you need some advice on how to do it.  We need to know what operating system that uses the Mac that you normally use to administer the time Capsule, provide good instructions, if you need it.
