hi there ...

lately updated my network to tp Link products ... no fancy configurations ... just plugged in & let go ... Router / Switches / APs all worked stable - all wanted enduser connected without any problems ... some of them got fixed ips - the rest goes via dhcp and most connected through my APs (Alexa / Hub / Tablets / Phones etc.) ... so i thought - easypeasy - lets change my smartplugs too ... bought 8 of P100 and none of them is willing to communicate :/

after a long journey of trial & error - i'm finally here ... hopefully to find a solution with u guys ;)

my setup - short overview:

TP-LINK ER605
    -> TP-Link TL-SG108E 
        -> div. Enduser
        -> TP-Link TL-SG1005P
            -> div. Enduser
            -> 2x TP-Link EAP653
                -> div. Enduser
                -> Kasa KH100
                    -> div. KE100
                    -> div. T110
               -> TP-Link OC200

my journey:

plug in - Kasa app opened - + - choose P100 ... and this is the final answer of all attempts

soooo ... like mentioned - pressed button for 5 sec - next try 

pressed for 10 sec - next try

pluged in another poweroutlet - next try

changed the range between my aps - next try

restarted my wifi on phone incl. bluetooth - next try

read some google-answers

unplugged all not needed endusers ... so only my main desktop & my phone were active - next try

tried this step also with another tablet while my phone was disconnected

changed wifi settings to only 2,4GHz & WPA2 - next try

changed the channel from 1 to 6 to 11 and back - next try

changed and tried every single p100 of my bought ones - but only with step 1 - 3 - next try

and my last attempt - connected Alexa & activated Skill Tapo & allowed everything - the no-brainer 4 dummys - as promissed - next try ???

somewhere i read - Tapo_Plug_XXX Wireless - should appear in wifis - nope ... just a side info

soooo ... now its hopefully your turn - guide my way pls !

thx in adv 

hope to read somewhat anytime soon !? ;)
