lost ping randomly

Running MikroTik RouterOS 6.38.5 on RBwAPG-5HacT2HnD.
Got a Canon ip7200 firmware v1.0 (latest).

Printer is connected on 2.4 channel1 (forced to channel1) and ping around 1ms and 900ms and sometime drop off ping..?? why?

Printer is 15 feet away from RBwAPG-5HacT2HnD (ceiling mount 8 feet)

The RBwAPG-5HacT2HnD is default configured in WISP AP.

Thanks!

Is the printer suspend mode enabled?
I had problems with HP Ink jet printers when was connected to wireless, even disabling the suspend mode, the print wasn’t accessible sometimes.

I will never again buy an HP printer. They get stuck in a continuous standby mode where you have to power cycle them to get them to work again.

Same delay directly from AP.

Thanks
