EDIT: Something odd I just noticed is the errors are the same for 2 ports. Traffic from my PC on port 9 and going to the GS728TP on port 16. I'm trying to think of a situation where the receive errors would be the same for 2 ports but 0 transmit errors. I can't really think of a reason for that beyond a software bug.

  @jra11500 Thanks for the reply. Wow, that's nuts, the thread was from 2015 and I specifically paid extra to make sure I got the most recent version of the switch. It's hard to comprehend they are still putting out switches that do this. I've sent a message to the supplier that I want to return it. See how I go. Maybe this issue on it's own would be ok but it's also coming up as 100M half duplex and the software for my cameras keeps dropping out and I have to push play again on the cameras. I'm going to buy another second hand Netgear. They have always been rock solid for me.

Thank you for your post. We’d like to confirm whether, with a 70 m cable, the switch can negotiate 1000 Mbps full-duplex when connected to the FS726T.
Regarding the packet loss you mentioned—roughly three times the number of data packets—could you clarify what exactly you’re referring to? We haven’t received similar reports before, so we’re inclined to suspect cable quality or other external factors.Additionally, please let us know if any special configuration has been applied on your switch.

Hi  @Ethan-TP, thanks for the reply. I was only able to get 100M half duplex over the 70M cable going to a Netgear GS728TP at the other end. When I switched out the TPLink for an FS726T I would get 1G full duplex with no errors. (see basic diagram below). Regarding packet loss, I'm not sure I was getting packet loss, just getting a large number of RxBadPkt errors. There is a large thread about it here https://community.tp-link.com/en/business/forum/topic/83046?sortDir=ASC&page=4. I moved the TPLink switch to a location close to the GS728TP and I was still getting RxBadPkt errors and my security camera viewing software would keep dropping out and requiring me to hit play again. According to the thread the RxBadPkt errors might not be real errors, although that combined with it not running at 1G and other issues I decided to return it.
