I have Chateau 12 Mikrotik router with latest ROS 7.1 beta2, which I am using as access point. I setup 2 WiFis - one for 2.4Ghz and the other one for 5Ghz. Since I have no point to use 2.4Ghz for now, I only use 5Ghz WiFi only. I don't know if this issue happens with 2.4Ghz. Main router is Mikrotik RB4011iGS+RM running latest stable version of routerOS 6.*.*.
Devices like laptops or smartphones are constantly being moved, therefore they disconnect and reconnect as they get away from Wi-Fi and get close again, but at some point some random device is no longer connecting to the Wi-Fi anymore. Android devices show "Obtaining IP address" and then "Configuration failed". Not sure about laptops, but most importantly - it happens to randomly "selected" device which no longer able to connect to Wi-Fi. All other devices work as expected without any issues. It's just happens to a random device.
In order to fix it, one can:
- Reboot router (it does not fix itself at all). Didn't try experimenting with wireless interface resets or similar kind of thing.
- Temporarily switch to 2.4Ghz until router is rebooted.
What I suspect
Something is wrong with Mikrotik WiFi drivers on "Chateau 12" or the way devices get configuration via WiFi. Something directly related to WiFi...
At home I have "Mikrotik RB4011iGS+RM" router and Netgear R7800 with OpenWRT acting as access point only. This setup is rock stable.
Now I have "Mikrotik RB4011iGS+RM" working as router and "Mikrotik Chateau 12" as access point only. And this setup is causing this issue...
