How many times can an internet connection interruption occur and still be considered acceptable?

No, it only shows that there is a fault somewhere between the ISP and 
the LAN port. It does NOT show there is no fault after the LAN port.

You are assuming that there is a single point of failure or only one 
bug. In reality there are many and they often cascade.

One of the software failures of that generation of routers is if the 
connection drops, the NAT tables are not refreshed. So some connections 
are NATed to the wrong IP address.

Another mores subtle bug is that the capacitors in the power supply for 
the router are starting to fail, which leads to random unpredictable 
results. The same with the WiFi, where a spec of dust or a minor change 
in a capacitor's or resistor's electrical value will result in major 
tuning changes, causing signals to degrade.
