TP-Link Deco M9 Plus is Stable with 1 M9, unstable as soon as an extra unit is added
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
As soon as I add a second M9 to the network the problem, NOT being able to reconnect (for a couple of minutes), starts. as soon as I remove the second and third M9 the wifi is stable again.
use case:
we have 3 deco M9
- 2 or 3 Deco M9 devices are configured for one network
- as soon as I leave the house the wifi of my phone will (of course) be disconnected.
- when I come home there is a change that wifi will not be reconnected (it connects and disconnects immediately)
al devices in our house do sometimes have this problem, not just our phones.
the problem is gone when only using one Deco M9, then the wifi is stable.
more info:
i have tried (probably) al setups that can be configured
- router/accespoint
- beamforming on/off
- fastroaming on/off
hopefully you can come up with a solution soon because I have no ideas left.
i'm not happy with this product. i'm more than a year bumbling with this hardware.
I tried to upgrade the firmware to 1.5.3 as you mentioned (methode 3). but i't is not excepting my TP-Link id.
I know I'm using the right network, right ID and password (incl. case-sensitivity), I do not use a vpn.
I even tried it with a direct (ethernet cable) connection in the main Deco M9 but this didn't help.
Why can't I use the android app to upgrade to this firmware version?
the android app indicates that the deco is up-to-date with 1.2.11 instead of upgrading to 1.5.3.
hopefully you can help me connect to the Deco M9 so I can upgrading the firmware
