Had my hub working and added a switch and now it can’t connect. Any ideas.
Had Internet modem > vintage > wireless router > hard wired stuff plugged in here. All worked.
Ran out of slots so added a switch.
Internet modem > TP-link desktop switch (plugged hub, myq gateway, wireless router and vonage in here)
The phone works. The wireless router and stuff hard-wired there works.
The my-q gateway and smartthing hub will not connect.
Any suggestions please!!!
