I have Mediacom cable internet. I talked with them and link aggregation and the 4 ports on the back of my Netgear cm1200 modem should all work.
I enabled link aggregation on the modem and Tplink ax6000 Archer router and connected cables to the ports in the instructions (1 & 2 on the modem and 2 & 3 on the router). After which, the router says the wan port isn't connected and there is no internet access. The router instructions do not say the wan port needs connected.
I tried plugging my smart TV into the modem: no connection. Same story with my Tivo and the base for my power line wifi extender. My laptop, however, initially didn't work when I tried, but after a while and maybe a modem reboot, it said it was connected to the internet, and said the network name was the same as the wifi related to the power line extender. That is weird for two reasons: the laptop wifi was off and the powerline base was plugged into the router. I unplugged the powerline base altogether and the laptop still had a successful internet connection under that same network name.
When the laptop is connected to the modem, the modem has a green light for that port. When the tv or powerline base is connected, they have orange lights on the modem ports. When the tivo is connected, it gets green, but still no internet connection.
Both modem and router appear to have their latest firmware.
What am I doing wrong?
