Networking issue.

  • Updated 2 years ago
I have a non-internet connected network at our mountaintop station. Running W10 Pro. It has four computers connected to it. on two of the computers, I am using USB to ethernet adapters. Up there, they stopped working after an update. So to do some in depth troubleshooting, I brought them to my house to work on them. 

The USB to ethernet adapters work FB here I updated W10. Took them back and the ethernet doesn't work. Changed out the router and switcher. Still doesn't work. Brought one back to my place, and it works. Placed in again, and it doesn't.

While not specifically a Flex problem, I do need the network to work and to use my radio with it.

Does W10 do anything strange now that it demands connectivity to the internet before it works?

I wanted to ask here before I fall down the rabbit hole. And I don't want to have ot bring the entire network and radios and computers down to my place.

I think the first question I would ask you is to better define 'not working'.

What does device manger show for these devices - are they present and does device manager show them as working?
Are you getting a link light?
If you look at the Ethernet counters are you getting any packets or errors?
Are these devices assigned static IP or are they DHCP addresses.  What are you getting for an IP address?

The answers to these questions may help narrow down where to start looking.

Device manager shows them as present and working. The networks connection panel says that the cable is unplugged. Cables have been checked and plugged into other cards to verify they work. 

At the remote station, there is no activity light on the cards or router or switcher. No packets either.

Each computer is assigned a static IP at the station. 192.168.2.10 through 192.168.2.40. Mostly for working with N1MM logger.

At the house, I generally use assigned IP's but can give it a static one if I wish. At home, they all work and see each other just FB.

By any chance when you FIRST plug in the cable does the link light LED light briefly but then goes off/out?  I've seen that behavior when there's a routing loop or IP address conflicts. How many routers and switches are there at your mountain top QTH?

Try checking Eventvwr System log focusing on going back in time to where the system last rebooted.  Check for any Critical (Red) events that may correlate to the link getting shut down.

Do you think it could just be Windows being a little vague? Like you state it says that "the cable is unplugged" , might it mean instead "the cable with the internet's ethernet signals on it doesn't seem to be connected"? I've seen PC's on my LAN claim "No Internet" when they are isolated from the LAN router that doing the DHCP. Does your LAN router provide DHCP services? I suppose it does, since it was working before. Without the Internet available at your mountaintop station. your only option might be drag those machines back to the Internet.

When you look at your network interface from Windows 10, do you have any number of packets being sent/received on this device?

W10 only wants Internet access to check your initial electronic licence entitlement.

After that you can disconnect, unless of course you mistakenly created a Microsoft account login. One device on the network (router, server, NAS etc) has to take care of DHCP and DNS that is it.

Your issue sounds like a device driver compatibility problem, or an IP address conflict to me.
