Frequent disconnects - High volume of Post RS errors

[hoppalong]

Good Morning, 

We recently (Feb/March) upgraded at end of contract and upgraded to the 500Mb Package. We have retained our Hub3 router which has been in Modem mode connected to a Deco M5 TpLink Mesh for the past 12 months with no issues. 

Since upgrading we are encountering frequent disconnects. I have checked all connections into the router & the wall and they appear secure. 

Looking at our Router logs there appears to be an increasing amount of Post RS errors. 

Our router was restarted last night about 10pm to reset the counters so currently has around 11 hours uptime.
