The problem was not solved, I bought and I have Mikrtotik Metal G-52SHPacn year 2019 and also a 2011UAS-2HnD with RouterOs 6.45.1 and they give exactly the same failure mentioned in the first message of this thread in 2014 ... disconnected, received diassoc : sending station leaving (8), comment, I have several home devices connected to metal 52AC, cell phones, tablets, etc. and none more than 6 meters away and most with direct line of sight, buy the equipment two months ago and since then connections are horrible in almost all devices that connect, (6 in total) the only device that goes well and does not fail is an old Chinese Tablet that navigates and walks as if nothing happened, the other computers all the time disconnected, received diassoc: sending station leaving (8), every 2 to 5 minutes, unbearable, I tried everything, everything, change of frequencies (channels), change of security .. change of data rates, etc. etc. I touched everything And for my last test I did Full reset to Metal 52ac, OS "Current Firmware 6.45.1" security default (without security), I only enabled wan by dhcp client and the nat in mascarade for internet access, nothing else, all default and connected by wifi only one device (sony xperia x performance with Android
to Metal 52ac and this device with little navigation load, web browsing news, 480p videos is disconnected and connects every 2 minutes approximately, being unbearable, just like before, but if the data load is maximum, for example video playback 4k .. the connection is stable does not fail, as long as it is playing and occupying all the bandwidth, if it pauses or leaves the video the connection returns to fail as before ... conclusion is that Mikrotik does not support modern energy saving system? or modern data saving? By disconnecting the devices that enter in that mode or change mode, is there any way to configure so that Mikrotik does not disconnect the devices? Try to keep them? pay for mikrotik 5 times more than the normal router Tplink, Zyxel, Huawei to have these problems ... ..
Could someone solve this problem?
and excuse my bad english
