Switches in Series, Newwork Setup GS108T

@chodson28,

Welcome to the community!  

Now I have the CAT 6 wired from the Modem to the switch to the final switch then to the shop computer.

Is your modem a modem-only device or a modem-router combo?  If ever your modem is a modem-only device, the correct setup should be: modem--router--GS108Tv3.  

When the switches are connected in series the last one says Standalone Mode and can not be accessed. Do I need a crossover cable instead of a standard cable? What is the best mode to be in this situation?

All of the RJ-45 ports of the GS108Tv3 supports autosensing.  It senses whether the cable plugged-in is a straight-through or crossover cable. 

I have lost connectivity to several smart devices is there a easy way to get them back online without starting all over on adding them to the system?

Where can I find info on best way to configure this setup or improve it?

Proper network connection/configuration will surely help. Post a detailed diagram of your current network (not in words, should be a diagram) as well as post another diagram of the network setup you wanted to implement.  In this way, community members can easily picture it out how to help you and post their suggestions.
