I do not see any brands that offer all I need. I’ll be setting up TMHI (T-Mobile), and a mesh network through the house, because the TMHI device will not be centrally located in order to get the best position for signal. I also have two out-buildings that need limited internet - looking at point-to-point for those, and access points inside. I can find everything I need, but not under one brand. Also - I need more than two hard-wired connections inside the home. but most of the mesh ‘masters’ I see only have two - one in, one out… SO - I’m open to suggestions, please! thanks in advance for any and all assistance!
Mixing brands is fine, assuming one of two things is true:
They are following the same defined standard (e.g. 802.11ax, not “mesh Wi-Fi”)
The proprietary feature you are looking for is contained within devices for that brand. IOW, that feature doesn’t need to interoperate with other brands.
Most mesh systems are proprietary, so everything within that must match (for the back haul connection). But you can also just setup another WAP, following the 802.11 and 802.3 standards. Similarly, your point to point devices can connect to other devices using 802.11 or .3, but not to the mesh back haul.
