Hello, everyone!

Due to changes after Android 15, there have been new updates regarding energy saving, which has caused issues in ipv6 connectivity due to low RA Lifetime for IPV6. Devices with Android 15 need an RA Lifetime equal to or greater than 180 seconds. If the value is less than 180 seconds, Android ignores IPV6. After  running many tests and troubleshooting, I have identified that TP-LINK routers/ONTs have a default RA Lifetime set to 30 seconds, with no possibility of changing this, and consequently all devices with Android 15 are unable to receive IPV6.

I kindly request that developers make an update to resolve this by setting the default RA Lifetime to higher value than 180 seconds of give us option to manage RA lifetime with min and maximum Retry interval as the options with ZTE modems. I will leave some attachments for analysis. Kindly Don't ignore this thread by saying that this is ISP modem and blah blah because i have already discussed with ISP and they cannot solve this issue at their level. So You Tp Link guys will have to intervene.

Similarly if we select and enable RDDNS via Lan Ipv6, it gets a lifetime of only 10 secs.

Please take it issue seriously and help us to find a perfect solution.
