I have about about 15 TP link switches in the house and they were all working fine until I decided to update the firmware on my router.  After it rebooted, only about 2 of the switches are able to connect.  

Switches: 2 x HS220 , 1 X HS210, 12 HS200

Router: Netgear Orbi rbk50

I purchased them over the last couple of years (so the versions are V2-V3) and just installed 2 HS200 yesterday. After the router reboot, a lot of the switches are blinking green, I tried restart the switch then do  a factory reset.  The HS200 go orange and green then I re-add them, it gets to the part where it allows me to choose the wifi network then it attemps to add it and within 5 seconds the wifi light on the switch blinks green.

Everything was working fine until last night then at 10pm I decided to do a firmware update on the router which messed things up.  My other devices re-connected fine but it's just my tp-link stuff that's giving me issues.  I just removed one of the switches from my kasa app this morning and will try adding it when I get home.

Any suggestions?

Thanks in advance.
