Crash Course In Configuring Layer 2, 3 Switches (HPE 1920 JG926A)?

Hi, I got a Hewlett Packard 1920 JG926A switch running version 1120 of the Comware firmware for a great price, but have very little knowledge of what I can do with it. I have an HP J8177C RJ45 SFP module I can use in it, but I was hoping someone would be able to help me figure out why it can't resolve DNS on say, pings to www.google.com, and why I can't seem to designate an uplink port.

The sole routing device upstream, and gateway, is a TP Link wireless router I'm using as a VPN server, and providing 2.4, 5ghz wireless access. All endpoints are currently uplinking to this via LAN port 1, using a 16 port 1000BASE-T switch. The HP switch is uplinking on the 16 port switch as well.

Topology is:

DMARC - Linksys CM3024 Cable Modem eth port 1 - TP-Link AD7200 port WAN

TP-Link AD7200 port LAN1 - 16 port Switch - HP 1920 port 24

IP's:

Cable Modem:

192.168.100.1

TP-Link Router:

192.168.1.1

HP Switch:

192.168.1.2

Endpoints:

All addressing on 192.168.1.x

HP SWITCH CONFIGURATION:

IPv4 Routes:Destination Mask Protocol Priority Next Hop Interface

127.0.0.0 255.0.0.0 Direct 0 127.0.0.1 InLoopBack0

127.0.0.1 255.255.255.255 Direct 0 127.0.0.1 InLoopBack0

192.168.1.0 255.255.255.0 Direct 0 192.168.1.2 Vlan-interface1

192.168.1.2 255.255.255.255 Direct 0 127.0.0.1InLoopBack0

Endpoints can access the HTTP UI of the switch, but without more knowledge, I'm at a loss if I'm on the LAN or WAN side, as I don't feel like I understand the wording and layout of the UI. If there's some better place for me to ask these "Wave a magic wand and make me great at this" questions, I'd appreciate advice. My goal is simply to configure a or a range of aggregated uplink ports, and pass traffic from the remaining ports through these uplinks. All this with zero experience using an HP switch. I was also told to buy a serial to RJ45 cable, and warned that I would thank them later, if I ended up configuring myself out of access to the device.
