Apologies if this has been suggested already, I've got too many irons in the fire and might have missed/forgotten if this was earlier said; I no longer use a wired router, all my computers are wireless so there is no physical ethernet connection to any computer.
I use the Netgear A6210 USB wireless Rx/Tx dongle and it is fast, very fast. Ethernet directly connected I get 300 Mbps download from the cable. With the Netgear dongle, I also get 300 Mbps. I lose nothing and eliminate that lightning path. As to the cable itself coming to the house, I have replaced the cable company's grounded F81 Barrel Connector between the drop line and the house with a 75 ohm grounded surge protector bought at DXEngineering, I use them on my two HI-Z RX arrays as well. After taking a hit to my just out of warranty, McIntosh tube preamp's USB this year, (forcing me to either pay big $ in repair or go with Toslink, I chose the glass toslink. (For audio only, the Toslink is excellent but with this system Toslink only offers one way communication from the computer to the preamp and some home entertainment utilizes two way communication). Fortunately, my needs don't require this. Those 75 ohm cable lines must be protected, just like our communications coax. 73, Gary KA1J > very good suggestions Wayne.
