Model: TL-R470T+  
Hardware Version: V6
Firmware Version: 6.0.4 Build 20200313 Rel.32850

Hello,

When I enable IPv6 on the router - the CPU on the router starts to ramps up from constant 25% utilization up to 100% over a 10 hour period and eventually becomes un-usable. If IPv6 is is then disabled the CPU load drops to 45% instantly. To return to the 25% utilization a reboot is required.

The router is configured with basic load balancing: 2 wan ports and one IPv4 policy route. SNMP monitoring is enabled. (no traps)

Any suggestions you may have will be greatly appreciated.
Thank you 
Sean

Hello, 

 

For the CPU issue, you may upgrade the firmware again (20200313 upgrades to 20200313) and see if it could refresh the CPU.

 

Besides, SNMP occupies CPU a lot. The bandwitch, amount of clients and behavior of the clients would also eat the CPU.

 

As I know, the maximum capacity of TL-R470T+ V6 is 30, NAT throughput is 95Mbps.

Hi @Yannie,

Thank you for suggestions, SNMP seems to account for about 3-5%. Amount of traffic has no bearing what so ever, this occurs if if all the devices on the network are off. The maximum traffice I could have is 7.5 Mb. ( Dual WAN - 3.5MB and 4Mb). I am already at the latest version of the firmware.

I would suggest to contact tp-link support when we cannot figure out the issue, especially when it seems to be the device issue.
