Server and client "no internet access" after changing out wireless modem

I just replaced my wireless modem (went from Netgear Nighthawk Model R7000P to Asus ZenWifi XT9). The internet comes from Spectrum who supplies the cable modem. I've put the new wireless router in the same location as the previous router and made all of the same connections. The router is then connected to a Tenda 24-port ethernet switch (TEG1024G). All clients and the server are then connected to this switch. I am able to get internet just fine on all wireless devices, but the wired devices, all clients and the WindowsServer2012, show "no internet access". I can still connect fine from the clients to files on the server. I seem to remember the same thing happening the last time that I changed out the wireless router several years ago, but I can't find any notes as to how I fixed it then and haven't been able to find anything similar when I google it. I know that the server has to be on for any of the clients to have internet, so I suspect I need to make a change on the server, but I'm not really sure where to look. After trying several things, it seems that some wireless devices get "no internet" if I have the ethernet cable from the switch to the server for awhile, but continue to work fine as long as I don't have the switch connected.

    Hello Thank you for your question and reaching out. I can understand you are having query\issues related to Internet connection. On the Windows server please check if there is any VLAN assigned . also please verify Gateway IP and DNS ip and change it as per your new Modem configuration. Please Disable any Antivirus program or Windows firewall you may have for temporary purpose. --If the reply is helpful, please Upvote and Accept as answer--
