Hopper does not see my wireless network

This is why I prefer hard wired connections. If your Hopper is not in a good spot to do ethernet , look into an Ethernet over powerline bridge. One device at your router, and one at your Hopper

The Hopper and Joey are probably communicating over the Coax if you don't have a Wireless Joey.

 

So you have a Hopper and a wireless Joey. Is there another device that is doing the wireless connection to the Joey ? Or are they both just connecting to your router ?

 

Wireless joeys communicate on their own network. They don't use your existing home wi-fi network.

 

That was sort of the point I was trying to make to the OP.

 

As already noted, the Joey/Hopper wireless is separate from your Internet wireless. In fact, there is a separate wireless access point (WAP) box connected by cable to the Hopper that handles the Joey wireless. When my Hopper was installed the wireless connection was weak and I had to buy a Linksys Velop whole house wifi (the installer had it) to make it work, even though the old router worked fine with other devices.

I got my wired 4k Joey and my wireless Joey to see my H3 and communicate using only my home LAN and home wi-fi. I disconnected Dish's separate AP altogether, and it's stuffed in a cardboard box somewhere. No use of MOCA either. I attached my H3 and 4k Joey to my home network using Ethernet to my home Gig-E switch (which is uplinked to my home broadband router). My home wi-fi is a tp-Link wi-fi mesh network also ethernet-attached to the Gig-E switch. Completely stable, streaming apps work great, recordings play back on all the devices, etc. This setup coexists perfectly with all the laptops for telework and virtual learning along with my 4k TVs that also play streaming 4k HDR from their built-in apps.
The Dish AP's stability was very dodgy causing me to unplug and plug the Dish AP and wireless Joey, and do the device pairing dance a couple times a week. My home network once employed ethernet-over-powerline extensively which was also dodgy, and I now have a half-dozen 300Mbps powerline adapters in the same cardboard box with the Dish AP in favor of the wi-fi mesh network.

 

It's unclear for me: did you mean "network" as different IP network or different WiFi RF channels or totally different RF freq ?

 

Absent DHCP, wired networks use APIPA.

 

Or if you have bridging turned off on the Hopper.
