any point of buying a wifi 6 router if the ont/onu is limited by 200mbps

Can you check if you are incurring the same issue when connecting via ethernet? Disable wifi or don't connect any devices except one device and that is through the cable. Also share logs, if Tenda router has one.
 
@Lolita_Magnum these are some logs. But at the moment I am unable to pinpoint the time when my internet was gone with this log file. at this moment the time in the router is:

@ssrahul96 I am more leaning toward wifi6 day by day although I only have 3 devices to connect. My LCO keeps spinning me round and round that I should buy an ONT(router cum wifi) instead of ONU + my custom router. He keeps insisting that this will solve my connection drop problem.
