DHCP, IPV6 and Debugging on MR60

Wondering if there's a more detailed way to log the MR60/MS60 daily functions and erros etc. For debugging purposes mainly. Other than the provided log under Administration---> Logs. I have been having some issues with the routers DHCP service, it advertises the same IPv4 to different devices causing one of them to go offline. I found that assigning Static IP's kinda solved the issue except that every now and then the Router will attempt to assign an IP out of the specified range. The log show repeated attempts of DHCP IP 192.xxx.xxx.xxx to MAC XX:XX:XX:XX:XX at etc time date. My question is why is the router repeatedly assigning this IP to this device when the typical lease should be good for a long time? The attempts happen one after the other within seconds apart. On a smart TV it was happening and it would disconnect from the WIFI and reconnect. The TV had its board and wifi card replaced only to then notice it was happening on other devices the same way. Another symptom I have had is the device has a valid IP address but cannot access the internet, but other devices are working properly. It seems that a power cycle to the router fixes everything, is this normal? or should I upgrade to a different router? Lastly even with the Routers IPv6 service it works after a power cycle and shortly some hours later its just not working anymore, I havce centurylink configured everything to their requirements but nothing. I know some routers you can access a developer mode by Telneting into them wonder if somehting similar would be available to the MR60. My firmware version is V1.0.6.116_2.0.54 on a MR60 Nighthawk Mesh Router and Satellites MS60.
