@drlou77 I have a Netgear Orbi mesh system. It utilizes a main router which is connected to my cable modem in a different room which holds a separate home theater system. The main router feeds a satellite router using a 866 Mbps wireless signal. The satellite router provides Internet connection to my Aurender N150 streamer. I consistently get 275 Mbps download speeds throughout the entire house.
My Ethernet cable upgrade saga began with a frequently recommended Generic Cat, 8 cable from Amazon as I wasn’t really a believer that an Ethernet cable could make a difference. I thought the treble improved but later learned this was likely noise that is frequently mistaken for improved high frequency response. So I bought AQ Cinnamon Ethernet cables. I started with the cable modem to main router and in the HT system another to the Apple TV 4K set-top box and another from the HT receiver to the TV. The difference was noticeable on video so I bought them for the audio system as well. I immediately heard less high frequency hash and as they burned in I could hear more natural sound.
MScaler to the Qutest brought refinement and later the Denali brought more noise reduction which resulted in more cable purchases. This time because I have all Shunyata power cables, I decided to go big and bought Shunyata Alpha v2 Ethernet cables. Same order as the last time in separate purchases except that I bought a Shunyata Alpha USB cable with the streamer feed Ethernet cable. These much better cables provided improved imaging, soundstage depth and tonal accuracy. The imaging improvement is incredible!
I don’t know your equipment or cables but I would recommend a better Ethernet cable on your streamer. Use a retailer with a long (e.g., 60 day) evaluation period because all digital cables require burn-in IMO. I’ve experienced digital cable burn-in many times now and the cables that aren’t pre-sale burned-in by the manufacturer tend to sound extremely closed-in or even harsh sometimes.
Happy journey!
