Windows 10: Can't ping router through physical Ethernet (Wi-fi works fine)

I have set up a Windows 10 computer, and initially I used a wireless adapter, but now I've moved it into my office and connected via Ethernet cable instead, it refuses to talk to the router. (The wireless adapter still works if I plug it in.)

I would like help understanding why a very simple Ethernet connection is not working. Here are the steps that I've tried, and their results. I apologise for the long post, but I've tried so many different things!

I booted the computer into Lubuntu, and it works perfectly.
The indicator on the router, and the LEDs on the ethernet socket indicate that there's a hardware connection, in both Linux and Windows. No hardware was changed, other than plugging in the USB stick.

I have tried using DHCP on the router (whose IP address is 192.168.1.1), in this case 'ping' says:

PS C:\Windows\system32> ping 192.168.1.1

Pinging 192.168.1.1 with 32 bytes of data:
PING: transmit failed. General failure.
PING: transmit failed. General failure.
PING: transmit failed. General failure.
PING: transmit failed. General failure.

Ping statistics for 192.168.1.1:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
PS C:\Windows\system32>

It seems that with this setting, Windows fails to see the DHCP server, so it sets its own random(?) IP address, which is not within the subnet for the router, hence the failure.
I have also tried manually setting a valid IP address (192.168.1.25) in which case 'ping' says:

PS C:\Windows\system32> ping 192.168.1.1

Pinging 192.168.1.1 with 32 bytes of data:
Reply from 192.168.1.25: Destination host unreachable.

Ping statistics for 192.168.1.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

PS C:\Windows\system32>

Note that during this ping test, the status page of the router lists 192.168.1.25 as having "active sessions" and 0 TCP and 1 UDP sessions are listed.

In the control panel, the Network status shows as:
"No Internet access"
Your device is connected, but you might not be able to access anything on the network.

Trouble Changing Wi-Fi Password


I've been following the following steps to change my Wi-Fi password for some time:

1. Launch Control Panel.
2. Click "Network and Internet."
3. Click "Network and Sharing Center."
4. Click "Wi-Fi...."
5. Click "Wireless Properties."
6. Click the Security tab.
7. Check "Show characters."
8. Enter the password in "Network security key."

Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?

 

Unable to see the local router Wi-Fi network


I am working on a friend HP All-in-one system that has a Wi-Fi interface. It came with Windows 10 so there has been no upgrade from a previous version of Windows. Some of the System Specification:

HP 23-r119c All-in-One Desktop PC
Intel Core i3-4170T CPU
8 GB of memory
Integrated Intel HD Graphics
Realtek ALC3228 sound
Wireless LAN 802.11b/g/n fetirung 2.4 Ghz 1 x 1 technology
(Shows in device manager as a Realtek RTL8188EE 802.11 bgn Wi-Fi Adaptor)
1TB Disk drive
CD/DVD burner drive

Side note I am not sitting at the system now and have no access. I am trying to see if anyone has seen an issue exactly like that. I did lots of research, seen lots of issues reported that are similar but none that fit my exact symptoms. Most fixes reported for issues where a Wi-Fi network is not showing up did not work for me.

So here it is. The connection to the local Wi-Fi router used to work fine. The name of the Wi-Fi network is BELL500. At some point in time the Wi-Fi network BELL500 disappeared. It does not show when I click on the Wi-Fi icon on the task bar. But other Wi-Fi networks do show up. Here is what I have tried so far.

• 1- Using my own laptop I was able to connect to the local Wi-Fi network BELL500 and had access to the Internet. So router and service provider are fine.
• 2- Downloaded the Wi-Fi adaptor driver from HP and install. To do so I first uninstall the device from the device manager and then ran the installation script I downloaded from HP. The Wi-FI adaptor was created and available network showed up. But the problem persists. Connection is not possible to local Wi-Fi network BELL500 since it is not listed in the available network.
• 3- Perform and sfc /scannow. There was no problem found. The problem is still there, the Wi-Fi network BELL500 does not show up.
• 4- Connected to a Wi-Fi network available from the list that had no security. It connected but it is a guest network and needed more credential to continue that I did not have.
• 5- Enabled my iPhone connection sharing. It showed up on the Wi-Fi list indicated that the service to discover the network also worked fine.
• 6- Tried to add and configure manually using control panel the BELL500 network. Even tried to use a different name. Did not work, never came up as a possible network to connect.
• 7- Shutdown the All-in-One system. Powered off/on the Wi-Fi router and waited for connection to work. Rebooted the All-in-One. There is no change for the local Wi-Fi network BELL500 it still did not show up. Other networks do show up.
• 8- Re-enable my iPhone connection sharing. It appeared on the All-in-One and I made the connection. I was able to get the All-in-One on the internet and it worked fine.

From all that it seems as if the Wi-Fi adaptor on the All-in-One worked fine, the Windows 10 services to discover and make connection to Wi-Fi network work fine and the router also worked fine. But from some weird and unknown reason the local Wi-Fi network BELL500 has disappeared and we are unable to get it back.

I executed a “netsh wlan show all” before and after the reboot. I put the result in 2 files that I have attached. Never saw the BELL500 network. The output are in french. If there is anything you need translated let me know. One thing I found strange on the output is that in the list of SSID there is one with no name. I tried the same command and I never saw an entry like that on my laptop.

One thing I forgot to do while trying to fix the problem was to search the registry to find if the BELL500 is listed anywhere. Is it possible that the Wi-Fi network BELL500 is still present somewhere in the registry, but that the registry entry is in a way that it would not display on the list, be listed with the netsh wlan command, would prevent the network to be rediscover and could not be used. If I found any entries in de registry with the BELL500 network should I delete them? Any idea as to what I should look at or do to try to clear the situation.

Thank you,

Luc

 

Wi-Fi, Ethernet, WinAudio fail to start on boot


I posted this on the Microsoft Community Help board and got little to no attention from the support engineers. Hopefully someone here can help.

I am having a recent problem with Windows 10. I have been running Windows 10 Home Edition from an on-line upgrade on my Lenovo Y510P for months with no issues. About a week ago, I started noticing that after a restart, my system tray icons for Audio and Network (either Wi-Fi or Ethernet) would start out fine but about half-way through the start up process would become marked with a red X or a warning yellow triangle with an exclamation point.

The Audio can be restarted either by running the trouble shooter or turning on the WinAudio service. The Ethernet actually works just fine but the yellow triangle warning icon persists and claims to either be constantly identifying the network or displays that the connection is unknown. Running the trouble shooter finds no problems. The Wi-Fi system tray icon appears with it's obligatory warning triangle and the Wi-Fi will connect to a known network if in range, but there is no Wi-Fi Icon in the Action Center, and no Wi-Fi entry in the Network & Internet Settings list either.

If you list the adapters in Network Connections, the Wi-Fi does appear and you can access the properties for the adapter, but if you try to select connect/disconnect from the context sensitive menu, it does not open a list of locally available networks, instead you are taken back to the All Settings Screen. Likewise if you run the trouble shooter on the Wi-Fi adapter when away from a known local Wi-Fi network, the troubleshooter tells you to pick a network from a list. When you click on the link, you are not taken to a list of networks, but rather back to the All Settings screen.

I have updated the drivers for the audio and both network adapters, The device manager claims all devices are operating appropriately. Malwarebytes reveals nothing.

I suspected the problem might be related shared service dependencies, but the problem persists through a clean boot in which both services and start-up items were tested. Neither a system scan nor a DISM repair revealed any corrupt system files.

I did notice that if I click on the "connect to the internet" icon on the log in screen, I do get a list of the dozen or so available Wi-Fi networks in my immediate vicinity. I can not see that list anywhere once I log into Windows 10 proper.

I created installation media (burned the Win 10 .ISO to a DVD) and performed a reinstall of Windows 10 which allowed me to keep my installed apps. I'm guessing both this and the basic system refresh maintain many settings and registry entries that are likely the source of my problem. Reinstalling Windows 10 did not resolve my issues.

I'm at a loss. Any suggestions?
