Why does OpenWRT router's ESSID disappear?

Installing and Using OpenWrt
1

I have 4 OpenWRT devices.
Their ESSIDs do not appear on phones's wifi list as quick as other routers do.
Sometimes it takes several minutes for them show up.
Is there a way to fix that?

Are you connected to an SSID during the scan?

No. Tablet is scanning for WIFIs and only OpenWRT router's SSID is not in the list. I takes some time for it to appear.

Configs?

Have you altered "beacon interval" by chance?

My gut says it is finding more than one of them and is deciding which to offer.

no, each one has different SSID

Tried channel 40?

  • What channel?
  • What bandwidth?

You can use OpenWrt's built in 'channel analysis' or an app like "WiFi Analyzer" to see congestion.
