Can incessant attacks on my wisp radio in Santa Cruz Mts bedropping service?

    Daily I see in my Ubiquiti AirOS log multiple attacks on SSH port 22.

    I also see periodic dropouts of the network, but they're not correlated
    1:1 with those attacks so I had never put two and two together.

    However, yesterday I turned off access to SSH on my rooftop radio,
    and my signal for the past 24 hours has been super clean.

    Here's the signal before I turned off access to port 22:
    (the red areas are pings that never returned, the blue is ping time0
    (the x-axis is in reverse time, e.g., 3pm, 2pm, 1pm, etc. moving right)

    Here is the signal AFTER I turned off access to port 22:

    The difference is so astounding, that I wonder IF the little computer
    inside the radio was getting hammered by the attacks, which perhaps
    weren't even showing up on the log file???

    Could that be?

    Turning off SSH solved the problem!

    For the past few days, I've been graphing the dropouts and the signal has
    been clear.

    So, it seems that leaving SSH enabled on a rooftop radio when you
    have a static IP address is folly because brute force attacks will
    eventually knock you off the net.
