Hi,
i’m having an issue
my laptop keeps disconnecting from MikroTik as below

any idea how to resolve this problem?
it happens from time to time

At first glance it looks like radio interference - connect using an Ethernet cable and use /interface wireless scan to see what other wireless networks at what frequencies (channels) exist around you. Google something about how WiFi actually works - in the 2.4 GHz band, only few channels (1,6,11 or, with newer specifications, 1,5,9) actually don’t overlap, so even a nominally different channel may interfere with the one you’ve chosen for your AP. If channel aggregation is used, the same can happen also in 5 GHz band. Some mobile applications for wireless scan show this graphically.

In crowded environments, it is actually better to use the same channel as another AP than a partially overlapping one, because in that case the two APs can accommodate to each other to some extent so they end up sharing the channel. On partially overlapping channel the devices just malform each other’s transmission.

thank you for your help
i have used Freq usage and then i chose the least used frequency and i will observe again

thank you for your instruction. it was helpful
