GS108 switch ports don't appear to be working

Hello KRas4, 

The GS108 is only a pass-through switch (pure hardware) and is not involved in giving away IP addresses. For your setup, the router is the main source of communication on the LAN (we'll take away the GS108 as a part of the networking equipment and consider it as a client). What you can do to isolate the issue are the following: 

1. Verify the connection again Modem>Router>Wall Jack. 
2. Take note that the Modem is responsible for the internet connection, the Router is responsible for translating the internet connection going to the LAN and providing client devices DHCP IP addresses. 
3. Make sure that every port on the router is working fine, verify this by checking if each device plugged into the ports gets an IP address. 
4. If this is verified, we'll eliminate the router as an issue here. 
5. Now, you have 5 wall jacks. (Question here, are these 5 separate wall jacks end-to-end or are they on a patch panel?)
6. If they are separate wall jacks, they all need to be plugged into the router. 
7. If they are on a patch panel, check each end of the wall jack if you can get an IP address. 
8. If you can get an IP on only one end of the wall jacks this will mean that your router does not give enough IP addresses or there is something wrong with the patch panel. 

The GS108 switch only relies to your router, imagine it as just additional ports and does not have the capability to give out IP addresses. Make sure that the wall jack where you plug in the GS108 can give you a connection and an IP. 

Thanks,
