Deco M9 Invalid wireless password error and general connection to wifi problems
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Have 3 Decos, 2 M5 and Main Deco M9, have removed 2 M5s from network and have continuing problems to connect from multiple IOS devices and Macbooks/Airs. As well as invalid password error.
Have rebooted to factory settings and set up network again but continue to have problems.

Hi,
Like this thread, please email our tech support to get the firmware to give it a go. https://community.tp-link.com/en/home/forum/topic/164184?page=1&t=2019%2F07%2F03%2007%3A31%3A46%20%2B0000

Hi Mad,
Thanks for your valued reply.
Glad to hear that it works for now, and the wifi network name won't cause the conflict theoretically.
You can take more time to test its performance and stability; any updates, just let us know.
Nice day.

@Mad From TP-Link support: Go into Deco App, More->Advanced->IPv4,
- Turn off obtain DNS Automatically.
- Set Primary DNS to 8.8.8.8, 2nd to 8.8.4.4

Did you have special characters in the password? I bet they didn't test firmware with special characters in Wifi password and that causes problems with some devices. Just my hunch, but I'd bet on it. Now I'm stuck with some devices that can't connect and have to start setup all over. GRRR

Exactly. All deco models does not accept special symbols in password for the Wi-Fi. Tested. Besides the blocklist is nonsense. First block, then allow, like in standard routers. Have no idea why TP Link is so lazy and cannot provide the functionality into deco models since long time. Next thing they do not provide is the option to change the channel. Explanation that system is selecting the best channel is idiotic and there is no logic behind it. One more time they are lazy. Next thing is port 22 opened. It should be some random port not 22 for mesh. And who for a God sake is using root for ssh connection? It is a matter of time when the root password will be guessed, hacked or discovered and provided. This is the basic knowledge in Linux. Never use port 22 and never allow root to connect on 22. I have no idea who work in TP Link but I recommend them to learn fast. This is not how the security should work. The 22 port is used for mesh network with hidden SSID which is repeated on the same channel - next nonsense.
