Internet Cable Connection

I appreciate everyone's suggestions. I took my cable toner and hooked to the cable from the antenna on the roof. I opened the Antenna Amplifier and isolated the cable coming down from the roof. I then put my toner on the cable I think is feeding the entertainment center coax and found it. I took and connected both of those two cables together and I now have internet. The reason I didn't just hook up down below with WiFi is I have to have a hard-connection for my work computer. I can't use WiFi with it.
I no longer have an antenna to use (it wouldn't go up anyway) so I will have to work on that another day.

Route your coaxial through a window and connect to modem. This temporary connection to make sure internet connection works.

I appreciate everyone's suggestions. I will let you know what my solution is.

Trouble with SAT cabling in that vintage of RV's they hid splitters in the cabling in strange places. Our 2005 5th wheel had one hidden behind a panel in the entertainment center. Our 2017 5th wheel was much better with four sat connections in the UDC, Two from the roof top pre wired sat location and one each to the bedroom and living roof TV locations. A 5th connection in the UDC was for park cable input which is routed to the OTA roof top antenna power supply in the bedroom closet. The back side of the power supply has 1. Cable input from UDC 2. Input from the roof top antenna 3. Cable to the LR TV plus the connection on the front of the power supply for the BR TV.

So one could identify the cable input run from docking station to the power supply and remove it, and connect it to the CABLE MODEM.

BTW our 2019 TT had a splitter hidden in the bedroom wall behind the power supply in the SAT cabling.

When snowbirding in Palm Springs, I subscribe to high-speed internet from Spectrum so I can stream my TV content via an Amazon Fire TV device and Hulu. It is provided via the normal cable TV connection at the site.

The first time I hooked up my router to a TV jack (the one with the amplifier), my internet speeds were very slow and intermittent. The Spectrum tech came out and identified the problem as "noise" being introduced by the amplifier circuitry. He said RV's are notorius for doing this.

The solution was to place the router in a "basement" compartment and connect it directly to the site's cable feed on the post. Works great.

I think that even if you are able to identify and fix the problem with your RV's wiring, the router may not work well when connected to it. Ultimatley, you may have to go with a solution similar to what I did.

Good Luck.

When we needed to hook up to the local cable internet connection we ran coax from outside into the RV at the bottom corner edge of a slide opening, and to a WiFi Cable modem router just inside. From there the Internet was distributed by the WiFi connection. Optionally, you could place the WiFi cable router outside the RV in a safe place and not need to run any cable into the RV.

Internet signal through cable will not like going though too many splitters and amp/switch. Try to find a direct connection. Many trailers will have a "SAT" cable run that can be used for direct connection.

I am using RG-6 Coax and I found the Antenna amp on wall. I took the coax that is feeding the TV (when amp is switched off I lose all channels) with AMP off and still no connection to the internet. I pulled the amp from the wall. It has 3 Coax attached. It looks like 1 feeding into amp and two coming out. I assume that this is a switch. When the amp is on it feeds the cable going to TV. When the amp is off I assume it feeds cable but it doesn't seem to work that way or degrades the internet signal too much to connect to internet.
I am going to try and feed another cable in to entertainment area and go from there.

Internet is normally connected with either RJ 15 or RJ 45 connectors not coaxial cable. Higher speed is done with a four wire connection using a RJ 45 connector, slower speed is accomplished through a 2 wire connection commonly a RJ 45 connector.
Most RVs are wired using RJ 15 connectors.

There may be a splitter in the wall or ceiling. You need to trace your cable and repair or replace as required.
