Networking :: No Network Adapter Detected - Deep Sleep Mode

May 5, 2015

I decided to take the plunge and install win 10 on one of my machines. Used windows update to install build 10074 from windows 7.

Everything seems to have worked fine except my network adapter (onboard Realtek thing) isn't being detected.

Figured this might be a driver thing so I installed various versions of the realtek drivers both win 7 and win 8 ones and these seem to install fine but then cannot detect the card. The installer gives an error that the card may be in "Deep Sleep mode".

Once installed the Device "REaltek PCIe GBE Family Controller" appears in device manager with no issues or conflicts, but nothing is in the Network Connections window when I go through Network and Sharing centre.

I have tried booting to the trouble shooting menu and selecting load unsigned drivers but this has not worked.

I rolled back to Win 7 and the card came back and all connectivity was restored. Re-installed win10 and back to the same issue.

How To Prevent Computer From Going Into Deep Sleep

Oct 9, 2015

How do I prevent my computer from going into a deep sleep after inactivity?

I have hybrid sleep off. Whenever I try to wake it up, it doesn't respond to any of keys except for the power button. That leads me to thinking it's been shut down, crashed, or is in a deep sleep. I don't think it has crashed.

Do I need to disable hibernation? If so, how do I turn it off permanently?

Networking :: Wireless Network Adapter Disappeared After Upgrade

Aug 8, 2015

So after 2 failed attempts at installing Windows 10 on an Acer Aspire Z5801 PC, I finally managed to succeed. However, a new problem appeared after installation.The Wireless network adapter went completely missing. Windows does not detect its existence at all, it's like the PC doesn't have one installed. It doesn't appear in Device manager + isn't listed as an "unknown device". It's simply not there at all.The wired network adapter is there, but not wireless.

Installing the driver from Acer's website - I had to select Windows 7 64-bit as the version is all that's available for my adapter.I used a USB stick to transfer the setup files to the Acer PC. It said it successfully installed but still didn't appear, even after a reboot.Used a USB wireless adapter (Netgear) to see if it was an issue with how Windows 10 handles Wi-Fi - nope, that installed and worked fine.Scanning for Windows updates after using the USB adapter. Some updates were found and installed (no driver ones though), but still no Wi-Fi.

In the end, I reverted back to Windows 7 and what do you know? The adapter got recognised again.The USB adapter isn't a viable solution since it's required by another PC. I just used it for testing purposes.

Networking :: USB Wireless Network Adapter - Connection Unstable

Oct 6, 2015

I recently brought a new wireless network adapter for usb (Asus usb N14) and since I've started using it the connection is really unstable, I'm on the same connection on my iphone and it's just fine but on my pc it's really struggling, I've ran speed tests and it'll work fine when randomly it'll just go down, I'll still be connected to the router but have no internet. Right now looking at the wifi graph in task manager it literally going straight up for a few seconds then straight back to 0 when downloading a file, and I'm unable to download any large files because it'll just fail after about 30 seconds.

I've updated it to the latest version with no change in performance or reliability. One other thing I'm at Uni so other people will be using the connection and I've no access to the router unfortunately.

Networking :: Wired Network Adapter Is Not Showing After Automatic Upgrade

Sep 15, 2015

I have DELL Inspiron 14R N4010. Automatic upgraded to Windows 10 Home. Previously I have Windows 7 Home Premium. After upgrade I didn't see the wired network adapter. However my wifi is working fine and can access Internet. I tried to re-install the LAN driver (Atheros AR8152 PCI-E Fast Ethernet Controller Driver); it ask for upgrade/repair/de-install means driver is already present in the system. In spite of that upgraded the dirver (got the upgraded driver setup from Dell). Unfortunately, the device is still not visible in device manager.

Installation :: Machine In Sleep Mode But There Is Network Activity?

Nov 27, 2015

I just upgraded from Win 7 to Win 10. The computer is connected to the home network via a gigabit switch. I notice that when the computer is in sleep mode ,there is still network activity but only the 10 mb/s connection LED is lit. When I had win7 OS and computer is in sleep mode , that same LED on the network switch would be off signifying no network activity at all .

Is this normal for Win 10 ?

Networking :: Airplane Mode Will Not Toggle Off In Network And Internet Settings

Aug 18, 2015

For some reason the Airplane mode setting can not be turned off in Network and Internet Settings, Network setting from taskbar, or Action center from taskbar. I am using my desktop and will never have it on an airplane. However, the computer does have a wifi adapter which I could use and it is able to be enabled.

Also, have other wifi devices on my home network, another PC and a tablet, a wireless printer and all are working fine. It must be a 'bug' on the desktop but someone should know that it is there. On the other PC, which is an all in one, the Airplane mode is not even in the settings anywhere.

I am on 10565 Pro version though this occured in last build too. Whenever I come back to my pc in the morning after putting it in hibernate mode for the night my airplane mode is always on. I notice it first by my bluetooth mouse being disconnected and then wifi connectivity.

The one fix I tried is unchecking the allow to shut off option to save power under device manager properties for my wifi adapter.

Networking :: Lose WiFi When Back From Sleep Mode

Sep 4, 2015

title says it. every time I turn on the computer, my wifi is always there. when I come back from sleep mode, it is not. no wifi options are available in the network section.

it is not signal strength. I had a slight USB issue, but as I said, I always get wifi when I turn it on, so seems any USB issue would show up when I boot either way..

is the power surge to the USB ports the same whether you boot from off versus from sleep? is coming back from sleep different somehow than powering up from off?

Always Loses Connection And Network Adapter Fails

Mar 25, 2016

This is all after upgrading from Windows 7 three days ago.
 
After two days of enjoying Windows 10, my internet just started going out. The pc would freeze for a sec and then id get a red x in the bottom and my wifi would be gone. In device manager, it always shows my wifi network adapter operation was unsuccessful. I switched to a different adapter and installed the latest drivers, which say are compatible with windows 10, and the same issue still happens. I also tried some CMD command I found online related to old VPNs and that didn't work.
 
Usually it only fixes if i unplug and replug the adapter. Disabling and enabling doesn't work. I repaired winsock and renewed tcp/ icp and that didn't work.. What can I do? I cant go 20 minutes without losing internet.

WiFi USB Adapter Not Showing In Network Connections

Sep 2, 2015

Ok so got a new usb WiFi adapter. I installed the driver first which I downloaded on my phone then transferred to my pc via usb cable. Have tried reinstalling multiple times, still won't work. I'm guessing the problem is there's no win 10 drivers for it. NOTE: I did have a old usb adapter working with no driver before but not even that's working even with drivers uninstalled. The new adapter shows up in device manager with a problem indicated with a code 10.But not in network devices.

Network Sharing Not Working Properly - IP Address Already Assigned To Another Adapter

Sep 16, 2015

I have a problem with Windows 10 Network Sharing feature. It assigns fine the IP address 192.168.137.1 to the network card that acts as the bridge to connect other computers to the Internet. But it's not working, and when one goes to the share NIC adapter and right-click on it and select PROPERTIES, and then from the list of it shows one select :

"Internet Protocol Version 4 (TCP/IPv4) then you see that everything is fine, the IP address 192.168.137.1 shows there and the subnet 255.255.255.0 also there. BUT ONCE YOU CLICK ON OK in that window, another Window POPS UP and a message saying:

"The IP address 192.168.137.1 you have entered for this network adapter has already being assigned to another adapter (in parenthesis it shows the same adapter that it's assigned in the SHARING tab in the main adapter), so there is not way to get out of that 'network card properties'. further down the message in that window says: DO YOU WANT TO FIX THE PROBLEM BY CHANGING THE IP ADDRESS FOR THIS ADAPTER? and the choices are: YES or NO

The command Line in an MSDOS window run as administrator: IPCONFIG /ALL doesn't shows any other virtual or real NIC with the IP address 192.168.137.1 except for the one that was assigned in the "Sharing" tab in the properties of the real NIC that connects directly to the ISP box.

I don't know if I have explained well this issue, but all I can say it's that no other network adapter has that IP address. I have a VirtualBox virtual adapter that it has an IP address totally different, the same as another Virtual VMWare adapter.

I even went to control panel > Device Manager > Delete both NIC's (the one that connects directly to the Internet and the one that acts as the SHARING network, and the issue remains the same.

I cannot use the Wireless Router to connect my tablets or WI-FI Cellphones.

I have several Operating Systems in the Same Computer to boot with, and Windows 8.1 for instance Network Sharing works fine in the same computer.

I'm running Windows 10 PRO 64bits

HP Pavillion G6 Notebook / WiFi Network Adapter Losing Connection?

Dec 5, 2015

OS: Windows 10 Home, 64-bit
PC: HP Pavillion g6 notebook

Network adapters: Ralink RT5390R 8-2.11bgn Wi-Fi Adapter (Date: 5/18/2015, Version: 5.0.57.0), and Realtek PCle FE Family Controller (Date: 4/01/2015, Version: 9.1.401.2015)
 
Problem: Every once in a while, I'll lose my internet connection. When I click the wifi icon on the taskbar, there will be no networks listed. The only way to fix the problem is to go the Device Manager, disable the Ralink Wi-Fi Adapter and then re-enable it. This fixes the problem anywhere from a of couple minutes to a couple of hours, then it happens again. 
 
Solutions I've tried: I've tried doing a system restore but it failed and there are no more restore points. I've tried uninstalling the Ralink driver, downloading a new copy, and reinstalling it.

Networking :: Internet Connection Can't Be Detected?

Nov 11, 2015

I've been running Windows 10 on my PC for a few months now. I upgraded from Windows 7 and absolutely love it! However, I am having an issue. When I use my PC on a normal basis, Everything is good. Internet connection is perfectly stable, no problems. But ALWAYS if I restart my pc, and SOMETIMES when I put it to sleep, when my computer turns back on, my internet connection can't be detected. I have to unplug it for about 5-10 seconds and do a full reboot in order for my internet connection to be detected by my pc. None of my other devices have this issue. I have an xbox one, Smart tv, my phone, laptops, etc. connected and none of them have the same issue.

Networking :: Ethernet Plugged In But Not Working - No Hardware Detected

Oct 21, 2015

I am having trouble getting my internet connection to work with an ethernet cord. I have no problem using wifi, but I get disconnected on wifi pretty frequently. I have two ethernet cords in my possession, one of them is new, and neither works. I've tried connecting to the router and the modem.

I've used used troubleshooter with both wires while plugged into the router and the modem. I've created a connection that has our given username and our password in it.

I turn off the wifi specifically by clicking on the wifi icon on the bottom right of my computer screen. It seems that the ethernet cord is not detected.

Computer Freezing - Processor 100% Network Adapter Turned Off / Occasional WHEA Blue Screens

Oct 16, 2015

My laptop, an Acer, has been freezing multiple times a day recently. Sometimes I get a blue screen eventually that tells me there's been a WHEA error, sometimes none of that. Yesterday, I kept staring at the screen for a while instead of restarting, and eventually it recovered. I could see the processor activity climb to 100%, and that interrupts claimed up to 14% of the activity. Afterwards, the network adapter (Qualcomm Atheros AR956x) was turned off, apparently because of a 'code 12' - 'insufficient available resources'.

That problem was only resolved after a restart. When I shut the computer down, I got a screen telling the computer was being 'prepared' for a long time - sometimes I also see a blue screen showing the installation of updates at start-up, even if none were waiting to be installed. The drivers for the network adapter are up to date, version 10.0.0.318 (apparently dating from May 2015). I'm quite sure this is a software issue - 'chkdsk' doesn't find any problems, nor does 'sfc /scannow'. And a friend of mine with an Apple laptop running Windows 10 (we've never exchanged USB sticks or anything) has exactly the same problem since installing Windows 10 (different network adapter however, and seems to have improved recently).
