Getting worse.

Down to 2 Decos now.

 Main Deco at 100% processor constantly also.

if anyone at TP-link is listening?

  @SteveWex They are based in Hong kong so won't see this till they get in in the morning. 

I also have stability issues with a new X50 PoE system :-(

@David-TP 

I've made the following changes:

• Removed the Network and restarted all the Decos.
• Recreated the Network using an alternative X55 as the Main Deco in case the original Main Deco was faulty.
• Applied the Firmware update to each of the X55 (V1)
• Applied the recent update to the M5
• Rebooted the entire network.

Result: Zero difference.

As you can see above, the network continues to show most clients offline. They appear and disappear randomly with the Deco, sometimes moving between Decos (so I can see 40 items connected to the 'Front Bedroom', then a moment later they might appear on 'Living Room')

The system is going through the various Deco Online/Offline status as before and the entire network is slow and unstable.

Other things of note:

• Decos appear and disappear randomly
• Main Deco is showing 100% CPU Usage

@David-TP 

Got it working again, but the only way I can get it to work is to use one of the M5 Decos as the Main Deco.

Hardly ideal as it's not as required by the list that wants the X55 first, plus I've lost all the X55 features.

Putting the X55 back in as the Main Deco created all the original problems. (This time using the third and final X55 as the Main Deco.) This seems to suggest there is a problem with the X55 being at the head of the pack.

As I need the outdoor Deco, I think the best option is to ditch these newfangled X55 in favour of 3 more M5 seeing that they work. As I only bought the X55 in April last year, I will try to return the X55 to Amazon for a refund unless some miracle occurs in the next 24 hours.

@David-TP 

Well as usual I guess the deafening silence says it all. I have come to expect nothing less.

Thanks for nothing.

Time to head for the Netgear pages to see what they can offer me in the way of a decent Mesh system.

  @David-TP - I am also experiencing the same issue.

5 x x55 updated to 1.5.5.

I've tried many things - switching the "Main" unit, many restarts, resets and power offs. Even tried introducing an x60. Nothing worked. Many of the symptoms described in this post - the non-Main Decos appear offline in the app (but aren't - I can logon via the web interface), connected devices appear offline yet the "offline" devices retain Internet connectivity. Decos would come online, then drop off again within minutes.

The thing that finally brought it all back stable was a downgrade to 1.5.3.

I guess I'll sit at 1.5.3 and wait for a fix.
