its a well known problem with version 1.6 I returned mine and requested version 2.6 and all the issues disappeared. There is a serious either hardware issue with 1.6 or firmware issue but 2.6 has not had any of these issues. There's a reason a new hardware version has already been released. My suggestion get the newer hardware I even worked with TP link engineers and still couldn't get 1.6 sorted out. Easiest way to tell the difference between the two versions is the packaging. 1.6 the box it comes in is huge and the units are packed vertically and standing up whereas 2.6 the packaging is smaller and the units are in there horizontally.laying flat down. That's the easiest way to spot the difference because sometimes they don't have the Hardware version listed on the outside of there packaging and sometimes they do.

  @BroncoP3t3  Probably the easiest way is to pick up each unit and check the version number on the label on the bottom.

  @jzchen 

if the units are out of the box yes you can do that but if there brand new sealed in the box then you can't check it that way and the box isn't always labeled 

  @icehawk940 Thanks for letting me know the boxes aren't always labelled.  So far I've been able to look at the SN/version on the boxes when shopping, (if the store has the item on the shelves).

  @BroncoP3t3 

you can do it either way if you get in touch with TP link and send it back that way request 2.6 hardware or if you go to a retailer like Amazon speak to a customer service representative and tell them what one you want. Like I said easiest way to tell the difference is the size of the box 1.6 has a much larger retail packaging box than version 2.6.

Found this thread after reaching out to TPlink a few days ago.

I’m having the same issue with Cox fiber 2g plan. Anything hardwired works fine, but the wireless connection is unstable. I get random drops that last from a second to a minute. Sometimes, a satellite with a red LED will pop upm1 or twice a week, but a hard reboot fixes it, but that’s not the main problem. The drops interfere with my work calls during the day and my girlfriend’s streaming to my devices at night.

Network setup:

- Cox 2000/2000 fiber test at 2100 Mbps average

- ONT Brand: Calix Model: GP1101X

- 3x BE63 HW version 1.6 firmware version 1.08 (2 purchased as a set, 1 about 3 months later)

- Wired backhaul

- 3x 2.5G switches Trendnet non-managed

I’ve reset all units to factory settings and tested the hardwired speed at each satellite. I also forced a connection to the living room satellite to rule out node switching. The drops are completely random in frequency and length. I have no idea what else to do except buy something else and hope TPlink can fix the issue during their return window. 

Has anyone had TP link support be able to successfully resolve their issue without a hardware swap?  And does anyone know what that  process looks like?
 

  @Knightfolk it's the hardware version 1.6 has tons of issues the newer 2.6 version doesn't. I had to return my original hardware and get the 2.6 and all the issues are gone

  @icehawk940 thanks. I hope they let me do advance replacement. All three units are all outside of the return window at Amazon. 
 

thanks again for the info. At lead I know it not me at this point. 

 Well, it's been 7 days and even though I was promised that the engineering team would get back to me but COB yesterday,I've heard nothing but raido silence. Idk how they think this okay. This is causing major issue with our work from home jobs. At this point I think my only option is to buy another 3 pack and hope at some point I'm offed a buy back for the original units. I suspect TP-Link makes the RMA process so ridiculous people just give up out of necessity. Very disappointing. Beware.
