Slaves frequently loosing contact with main Deco P7
I seem to have version EU/1.1 (3 pack Deco P7)
I experience since several months back from time to time lost contact between the two slaves and the main Deco, which then still works (as AP) as it should. Upon rebooting the main Deco unit, the connection with the slaves is re-established and everything works again - untill the next time.....
This is very frustrating as this should not happen in the first place and secondly, it requires a manual reboot of the main DECO, close to the main router, which is located somewhere else than the two slaves.
Configuration: Router ASUS RT-N66U --- Main Deco --- ethernet cable class 5E--- TP-Link switch TL-SG105E --- ethernet cable class 5E --- TP-Link switch TL-SG105E --- slave 1. Slave 2 is wireless connected to the Main Deco. Several units (PC's, TV, etc) are connected to the two TP-Link switches. I have no other switches.
When I first experienced the disruptions, I replaced my two previous D-Link switches with TP-Link switches ("could be the reason" acc TP-Link website), but that was clearly not the reason for the problems, as it made no difference :-(
What is wrong here?? Please advice me what to do! I need to be able to rely on my system, as I run a webserver and an email-server on my network.
I am pretty much ready to switch to something else by now...
