Model: TL-PA9020P-KIT
Hardware Version:
Firmware Version:

Searching the forum was not productive.  Please forgive me if my question is "something everybody is supposed to know."

 

Have four PA9020P adapters installed for over a year.  Working fine.  Today, I realized some devices were off-line and discovered that all four Powerline units are showing RED LED's.  The tp-link utility connected to the primary unit will show only 1, then sometimes 2, and sometimes 3 adapters.  The fourth one has not appeared (yet).  No changes to electrical wiring.  No changes to anything that I can think of.

 

How do I fix this?  Should I go around to one after another and perform a "reset" until Powerline magically heals itself?  Should I unplug them all and start over?

 

Thanks

@CrimpOn 

 

A Red Powerline or homelink LED indicates a poor signal.  The main thing that causes signals to become poor is interference.  Interference can be caused by many things but the three main factors are,  Age of the physcial power line, Poor Insulation of the power Line, and devices connected to the power line, particularly major appliances.  The first thing to do is move the adapters into a different room and see if the indicator LED changes.  If not then move the adapters one at a time into the same room but in a different outlet as the main unit and then check the indicator LED if still red try updating the frmware or contact support as you might have a defective unit to replace.  As three units are doing the same thing that would seem unlikely though.  

 

Next thing to try would be to "filter" the noise out by pluging major electoric devices suchs as stereos, TV and computers and major applicances into surge protectors.  Keep in mind there is a difference between surge protectors and power strips.  One filters and protects that other does not.  

 

This would be where we would start.

Thanks for responding.  I am glad there is "somebody there."

 

I was able to resolve the issue (at least for now).  I noticed that only one of the four units would NEVER appear on the tp-link display.  So, I went to that unit (1) did a 'reset' by holding the sync button for 15 seconds until the LED's went out and only the power LED came back on, (2) did a fresh 'sync' by pressing the Sync button for 1 second, then dashing through the house to press the 'sync' button on another Powerline.  Now, all four units show green LED's.  The tp-link display shows all four of them.  And, the transmission rates look about the same as they always were.

 

This has been a learning experience for me.  There must have been something that messsed up my Powerline network, and I will probably never know what it was.  At least the next time I will give this a show before displaying my ignorance.

Hi!

 

I have the same issue with TL-PA9020P-KIT.

 

I have 2xV1 and 2xV3 TL-PA9020P-KITs.

 

They are working fine for example for two weeks and after some time 2 of them randomly have solid red led and tranfers are very slow. Sometimes I need to pair them one more time. I think it is not related to any interference in my AC network because if I restart main house AC power switch they are going to be green. So it looks like they are halted for some reason and only reboot helps them. I think it is firmware issue and need to be fixed.

 

When new firmware fo TL-PA9020P-KIT will be availiable ? It is one year without any update to TL-PA9020P-KIT firmware.
