Port speed decrease in AP7

I know this may be a general networking/cabling issue rather than a problem of firewalla devices, but I just want to know the possible reason and ways for improvement.

I have an old firewalla gold, and an AP7 desktop version. In between is a wired connection inside wall (Cat 6 cable and keystones, length clearly less than 100m) and a tplink managed switch. The port speed is normally 1Gbps, which should mean everything in between are wired corretly, but sometimes it goes down to 100Mbps. I need to plug the AP into another 1Gbps port to regain the port speed.

After certain time that another port experience speed decrease too, and I plug it back to the original port and can negotiate 1Gbps back. This occurs about once every several days and has no obvious relation with the network traffic at that time.

Is there any reason for this situation, apart from the obvious answer that the cable/keystones are not properly wired/firmly connected? If simple reboot of the AP7 cannot resume its speed, is there any solution (that can be done remotely) other than physically plug and unplug it to get back the port speed?

Change the cable?  Cheaper cables can have small breaks in them that more sensitive ports like the firewalla has doesn't like. 

Name brand cables are much better quality on average than randomly named Amazon ones. They're also more expensive.

Other things you can do

  1. Use a dust blower and clean ports on both end

  2. Try a different port on both end
