It happens with all cables, they are not broken. I did figure it out yesterday though, there is a major design flaw. There are two halves (clamshells) which come together to form the unit. The half which does not have the RJ45 connection is not notched and partially blocks the tab from the connector from fully clipping into the port. If the cable is pulled on an angle towards the tab it pops out as the tab is pressed into the edge of the plastic clamshell. If it's pulled on an angle away from the tab then it does not pop out.

 

This could be avoided by having installed the RJ45 port at 180deg so the tab portion is away from the other clamshell OR the clamshell be desigened with a notch as to not interfere with the tab and operation of the port.

 

I really don't see how this design flaw could pass though the processes of a major hardware vendor such as TP-Link. It's honesly like designing a car where the tires rub on the frame when you turn right. Sure it "works" but it's bad and should never happen. 

 

Interesetingly the photo below is NOT how mine is, my RJ45 port is 180deg from the photo and so has the problem I mention. Also mine has no metal in the ports it's all plastic. Has TP-Link has made the design cheaper and it's now causing problems?

 

 

 

I've just bought an 8080p with the very same problem - all 3 ports affected by same design floor. Did you send them back or just live with it?

I just live with it. Since the units are behind a TV it's not a huge deal as it's not touched/disturbed. I bought another set 6 months ago and it does not have this design flaw. It's just plastic, so if you really wanted to you could melt or cut out that bit of blockage to 'fix' the issue, but I doubt you'd need to worry about it.
