Network numeric passwords blocked
Around one month ago I bought a set of tp-link Deco S7 mesh units, and installed them in my house using the same network name and password of an old repeaters from another brand. Setup was easy, and I could use the same password of the previous network with only numbers, to avoid the need of reconfiguring all my devices. I was happy with the results, the network signal and speed were much better than when using old repeaters, and all devices reconnected automatically.
Yesterday I reset the S7 units and tried to reconfigure them to another network name and password. For my surprise, the app did not allowed me to use a password with only numbers, it requested letters and special characters as mandatory. I could not even set the units back to the previous network name and password that I initially configured, because of this limitation.
So, is there a way to set a network password with only numbers in S7 mesh units, to avoid needing to reconfigure all my wifi switches, tvs, alexas and ther devices to use a new password?
Thank you!
