I would say so. It is introducing interference and noise on your line.

More than slightly imo. Of course we don’t know how long of a run this was. But for a single Ethernet drop by itself anything over 250-300 to start is price gouging in my book.

That’s insanely overpriced. But I think the first mistake is getting an electrician instead of a low voltage tech.

I went back n fourth between the 2 myself. Took about 2 weeks for me to decide. I ended up with the 8 port only because I figured I wouldn’t be getting more than 8 U6 enterprise AP’s and the cameras are all 1Gbe so I didn’t see the need. At some point I will get a 24port but most likely a professional and not the enterprise.

You could save some money by getting the entripsrise 8 Poe. Unless you plan on using more than 8 Poe devices.

I don’t think it really matters feature wise. From what I’ve seen the only difference is the U6LR covers 500 more sqft than the others.
