So i have 2 access points in the house one is on the first floor and the other one is on the second floor.
Now for the first floor access point i have set up an ACL (only wlan1 is enabled) (SECOND AP)
/interface wireless access-list
add interface=wlan1 signal-range=-60..120 vlan-mode=no-tag
add authentication=no interface=wlan1 forwarding=no signal-range=-120..-61 vlan-mode=no-tag
Second floor access point has wlan1 and wlan2 enabled with ACL configuration as follows (MAIN AP)
/interface wireless access-list
add interface=wlan1 signal-range=-89..120 vlan-mode=no-tag
add authentication=no forwarding=no interface=wlan1 signal-range=-120..-90 vlan-mode=no-tag
add interface=wlan2 signal-range=-89..120 vlan-mode=no-tag
add authentication=no forwarding=no interface=wlan2 signal-range=-120..-90 vlan-mode=no-tag
Now i have this one lenovo laptop that has connection issues so i started logging. I got information that yesterday around 20:20 there was a disconnection issue so i looked at the AP's logs.
Side note: the laptop was not moving it was on a table.

From the logs it looks like the laptop wanted to randomly connect to the other AP (group key update is 1h so maybe that was the trigger).
Now as it is too far and the signal strength is too weak it gets rejected. However the AP that it is connected to now says that it is connected to antoher device on the network and disconnects it from that interface as well.
The end result is that something goes haywire in the wifi chip on the laptop and it now has no network access at all for a while.
Any ideas here?
