@Ram_Eswar  having same problem 

  @Kevin_Z Hi, Before two week i got replacement tplink xx530v from tplink service center. that replacement tplink router came with pre installed

firmware 0.6.0 3.0.0 v6096.0 Bu1ld 250422 Rel.46744n. by default i didn't enabled CWMP TR069 protocol which worked without EPON Registering Loop error for 12days so 

i came to conclusion that CWMP TR069 protocol caused EPON Registering issue but iam wrong after posting my findings to community, by next day on power cycle router again faces EPON Registering loop error and router didn't registered until next power cycle. but after 8 hour power cycle resume it automatically became EPON Registered status.

** Today i installed Firmware Version : 0.7.0 3.0.0 v6096.0 Build 250606 Rel.25672n and again by default CWMP TR069 protocol not enabled, but as like my previous old xx530v router this replacement router also started facing same frequent EPON Registering loop issue after random power cycle.

** Youtube link TP Link xx530v EPON registering loop error - YouTube here in this video you can find i able to recreate EPON registering loop if i turn OFF & ON router few times

So firmware 0.6.0 3.0.0 v6096.0 Bu1ld 250422 Rel.46744n didn't cause very frequent EPON Registering loop error like firmware 0.7.0 3.0.0 v6096.0 Build 250606 Rel.25672n**

** By disabling CWMP TR069 protocol wont resolve EPON Regsitering loop error, this router requires firmware update to rectify this issue.

  @Kevin_Z No older firmware 0.6.0 had similar EPON Reigtering loop Error but faced once in a week during power cycle, but this firmware 0.7.0 has very frequent that is 4 to 5 times per week on power cycle. 

Yes, i contacted your local support spoke with L2 engineer they contacted me via phone and connected them to this router via ultraview they just checked firmware version

and told me to get router replacement, now that replacement router to facing same EPON registering loop error.

also Shared all video link to L2 engineer phones whatsapp

**  Even i checked my cable operator OLT by myself he is using Optilink 11444 epon OLT, checked all logs but its not showing any errors related to EPON registering error to this xx530v, just showing status as offline during EPON Registering Loop, checked all other random ONU which are not tplink but all other 5 ONU(Netlink) which i checked are all my neighbours which are working normal showing status as online, My side Cable operators OLT only uses auto MAC authentication i am not able to see any other serial number or LLID of any connected ONU.
