Our Decos systems use WPA2/WPA-AES/TKIP mixed. Could be some devices saved the wireless profile different than that of those which did connect back successfully. Forgetting the network or changing the password create a new saved profile.

One of the issues that I still can't get an answer on is the Password requirements... Does Deco require any minimum / maximum / combo of alfa-numeric? It appeared that way when I was directed to set up a separate account in GUEST.. and my standard 10 digit alpha / numeric was simply rejected.... On a hunch I simply added one letter and it accepted it.

After 4 times Resetting Each Deco and attemptong to get them to be recognized by my devices, I changed the SSID Name to lower case, and added one letter to my 10 digit password string.....

 

That worked, though I woud have like to know what were the requrements for Name & Password for this product. It would have saved hours of work........

 

 

 

 

@Wizard99   Did you get all devices working using the Mesh Network and same SSID and password as your WIFi?  Or did you go around to all your devices and change what they connect to?

 

I am having the same exact issue, similar post, as you.

 

Thanks for any help

Here's the end of the Story....

 

For a 4th and final attempt, I again RESET all 3 Deco's....  

 

I then changed my Credentials slightly.....  Changed my SSID name from Upper case to all Lower Case..... Then added ONE LETTER to already 10 alpha-numeric current Password....

 

It then worked.....  Please know that this was suggested previously by the Help Staff... not how to change it, but just change it.... I resisted this as it made NO SENSE to me....

 

I was skeptical because no one could give me a reason as to why this would allow me to re-connect to my devices.... the CSR's could not even provide me the official SSID and Password minimum/maximum requirements for these devices.........

 

And IF my old SSID and Password WAS being stored somewhere and this was interfering with the New Deco's, I would sure like to know here this was occuring.... especially since "Resetting" the Deco's should have cleared everything off.... 

 

As mentioned, the only reason I wished to keep my old SSID and password was that I would need to change EVERY device in my home. Not a simple affair as I've just finished Deleting and adding 56 Devices.. many IoT Switches and other not freindly to change devices..... Plus updating all the Alexa Routines... ARGGGHHHH!

 

And I also found I could no longer connect to my ethernet connected NAS! All the Mapped Drives were lost... Those all had to be deleted and Mapped again....

 

All the reviews I could find and read on TP LInk Deco and any other Brands for that matter of MESH Routers all dealt with initial Set-Up issues...  None spoke of the need to wipe and start over every device you may own.

 

Wish there had been an easier way of course....... and hope these don't fails and need repalcement!

 

 

 

@Wizard99 I set up the Deco as an access point off my old WiFi and then set up the Deco with a new SSID and password.  I will then migrate everything over and then remove the old WiFi, hopefully...  So far so good doing it this way..

 

Good Luck

@Ralphie Good News..  I kind of followed the advice from this thread.  I setup the Deco in AP mode, created a new SSID/password and was able to move everything but my 3 Insteon (Foscam) cameras.  Has anyone done this?  Any advice?

 

Once I get the cameras either moved over or replaced, I will then switch the Deco over and remove the older WiFi..
