Hello @SDHINESHKUMAR 

 

When the Wi-Fi keeps disconnecting, how about the internet LED on the C80? Is it orange or green?

 

If the internet LED turns orange, please go through the troubleshooting suggestions we provided in the following thread, locate if the issue is caused by the ISP or the C80, then report back with the details:

Router Disconnects from Internet

 

BTW, who is your ISP?

It is my local ISP provider.. I have checked with my another Asus router and it works fine without issue..

I'm a little confused. Do you mean the internet LED on the Archer C80 will turn orange but you still have internet access when connecting a computer to the C80 with an Ethernet cable? Please confirm the disconnect issue again. When the internet LED turns orange, please login to the web interface of the C80 and confirm what is the WAN IP address at that moment. BTW, what is the WAN Connection Type on the C80?

 

Please save and send us the system log on the C80 as requested in the thread I posted previously, then we will try to investigate further.

@SDHINESHKUMAR 

 

1.11.30 Build 220624 Rel.50807n(5553) should be allowed to downgrade to the previous 1.11.0 Build 220425 as per the release note, there are no limitations on the downgrade. Can you please confirm again?

 

If it is not allowed to be downgraded, please don't worry, the support engineers should help further with the issue. Please let me know if there are further inquiries.
