Ethernet issues?

How can I fix the Ethernet problems on Windows 10?

Check for viruses.

Check your drivers.

Check that the connection is enabled.

Check the network cable.

Check your connection details.

Run the Internet connection troubleshooter.

Roll back the network adapter driver.

Turn off your firewall and VPN software.

So how could they wire it? Does it go to a board or is it a lot of wires out of the divider? Anything out of your switch needs to go from one of the switch LAN ports to a wire to a room.

The ethernet cord from the wall should NOT go to the WAN port on the router. The WAN port should connect to the line that goes out of the house or if it's broadband/LTE, then none at all.

DHCP is supposed to make everything automatic but sometimes it doesn't work. Look under your router for its IP address. It's a set of 4 numbers separated by dots (eg. 192.168.0.1 or 192.168.1.1). In each computer, go to Network Settings, IPV4 and set the Gateway to your router's IP address. Click the Validate option before Saving. 

The simple answer is to get whoever came out in the first place to come back and fix the problem

the six port must be a HUB and NOT a SWITCH.

=====================================Routers are of TWO types.Type 1) this requires a WAN IN socket for broadband input from some sort of modem and 4 LANS OUT thus it has 5 sockets ONE colour coded separately(to identify) WAN IN from a separate MODEM.Type 2) takes either optical cable IN or Telephone Cable in and provides 4 LANS OUT.If you have Type 1 then your WAN IN must be connected to a Broadband source eg if you are in a block of flats it would be your 1 LAN wall socket. If its your own Home then you need to plug in your MODEM to it using the short 1m LAN cable that came with it. If you dont put it IN the IN socket then it wont work.If you have Type 2 then you must attach your CABALE or Telephone line and then you have 4 LANS out. In some cases a business version might provide ONE high speed LAN and several Lower speed LAN sockets but they are all OUTs. You can then add a HUB(not a SWITCH which may look similar) and the Hub acts like a RING of connections and you plug IN a single cable to it from one of the 4 LANs OUT of the Router(if its a business one then use the HIGH speed LAN socket it will clock down to lower speed if your HUB is lower speed). You then connect the other HUB sockets to individual PC's

so you may have purchased a SWITCH and NOT a HUB.

hope that helps

As you plug the router or any device in to a wall socket, you should get a light or lights on the Netgear switch, either next to or relating to the port on the switch where that connection ends up.

And some light/lights on the socket on whatever device you are connecting.

If any wall sockets do not work properly, the most likely reasons are a socket not properly wired, or a faulty ethernet cable. Or just a missing patch cable.

Sometimes the insulation does not cut through properly as the wires are pushed in to the socket terminals with a punchdown tool, or if the tool "wobbles" it can twist open the blades that should grip the wire and it not connect properly.

Or wires can get swapped over by mistake..

The wiring should have been done with "trunk" cable and a socket either end - the wall socket one end and a socket in a patch frame at the other, then connected with short (patch) cables from there to the netgear switch.

If the installer has put plugs directly on the main cables, I'd be extremely suspect of that. Normal Ethernet plugs are designed to fit flexible, stranded core cable.

Sockets are intended for trunk - single strand core - cable. You cannot usually have both a plug and a socket on the same piece of cable and it work reliably long term, with either cable type..

[There are special plugs to work with trunk cable but they are extremely rare. 

Each contact piece has zig-zag teeth on the base that fit around and grip the single strand, rather than the normal spikes intended to puncture and go through the centre of a multi stranded wire].

Yes there is something your doing wrong.   Each Ethernet Cable from the rooms has to have it's own Ethernet Port. 

Your Modem/Router should have Four Ethernet ports and those can feed Four Rooms.

All of the Ethernet Cables should come back to a single place. So if you have (as an example)SIX Rooms, then there should be a Wall Plate next to your router with Six Ports.

You then use FOUR Patch Cords to go from the Router to any Four wall plates.

Ethernet Cables CAN NOT be Daisy Chained like you do a PSTN Telephone line.

If you want to feed all the rooms at the same time then you need to purchase an Ethernet Switch with multiple ports.  You can get them with Six Ports, Ten Ports,  24 Ports or even 48 ports.  Your router Feeds Port One on the Switch and the Remaining Ports feeds your rooms. This is a picture of an Ethernet Patch Panel.

So how did they wire it?  Does it go to a panel or is it a bunch of wires out of the wall? Anything out of your router has to go from one of the switch LAN ports to a wire to a room.

Update:

So first, I would test the router's LAN port on the router to see if you get an IP can get internet.  Just plug in a laptop.  Every LAN port is equal, but you only have 4 or 5 because the LAN side of the router is limited.  It sounds like they left a 6 port switch, there has to be a ethernet cable between the router's LAN port and one of LAN ports on your switch. It does not matter which one.

Lastly, if that works, then try any of the ethernet ports on the Netgear switch. (except the one feediing the switch).  This should work, you get an IP and can use the internet.  Then all the other ports have to have a cable to each connector for each room.  I don't know what was left, but it is either a patch panel like above, could be a wall connector with a bunch or ports or maybe it is a bunch of cables. 

It sounds like the cable modem should be:

wall coax to router

router (one LAN port) to any port switch

rest of switch ports plugged into each room

BTW, if you connect two cables from the router LAN to switch, it will turn the switch logically off, so don't do that. Once you connect the cable to the switch, all the ports are equivalent so if you have 6 rooms, you need 6 ports.  If they feed the switch with one, you have to use one port off the router itself + the 5 remaining ports on the switch if you have a 6 port switch, because you used one to feed the switch).
