RT-AC66U CPU at 100%

[PhilNE]

I'm using 376.48_3 and the CPU is constantly at 100%.

The TOP command via TELNET is showing.............


Mem: 68052K used, 171480K free, 0K shrd, 8560K buff, 29196K cached
CPU: 5.1% usr 94.2% sys 0.0% nic 0.0% idle 0.0% io 0.1% irq 0.3% sirq
Load average: 1.00 1.00 1.00 3/47 3798
PID PPID USER STAT VSZ %VSZ CPU %CPU COMMAND
1 0 admin R 5608 2.3 0 99.0 /sbin/init


Is this normal please???

Cheers
Phil

Have you tried resetting to default settings? I think it is in the Administration tab.

Disable DLNA Media Server and iTunes Server

 

[PhilNE]

Thanks Nullity and fearlegendz.... tried both but still the same.

Another problem I'm having is that if the router is switched off I have to do a factory reset and go through setting it up from scratch.

Clean your NVRAM and Reset to Defaults, after configure it manually, do not import any old config file to the router.

After doing what hggomes suggests, if it still doesn't work, please report what is in the system log (using the gui).

If you don't have NAT acceleration enabled, then any Internet connection close to 100-150 Mbps will push the CPU load to 100% on the RT-AC66U.

with this parameter, normaly you loose the parental control.

 

[hggomes]

Take a look at the process:

1 0 admin R 5608 2.3 0 99.0 /sbin/init

 

[PhilNE]

Thanks for all your suggestions but I think it may have finally died...

I updated the firmware to 376.49 but after it rebooted the power light just flashes like a strobe light.

Tried the firmware restore utility with no luck...

 

[hggomes]

That means its on "WPS Processing" state, try to press RESET before power on and see if the Power LED blinks slower, if yes then you are on Bootloader Recovery Mode, you just need to upload your FW via TFTP or http://192.168.1.1

with this parameter, normaly you loose the parental control.

Correct, as well as Traditional QoS and IPTraffic support - all incompatible with it. But if your Internet connection is faster, you will have to chose between losing these features, or not being able to reach your ISP's full performance. In that case, you need to buy a router with a more powerful CPU.

Thanks again everybody....

I think I've got a dodgy WPS button....

Only time I push 100% on my AC66U is when QOS is enabled and my speed approaches 110+mbit.

Has nothing to do with turning off Nat acceleration as i can turn off QOS and turn off Nat acceleration and 120 mbit i get with with QOS off will only put the cpu at about 35% with NAT accleration off and if put Nat Acceleration back on the 120mbit with QOS off will still be at about 35% cpu.

QOS is HUGE hit to the router cpu. i mean yah QOS disable Nat acceleration but. Nat acceleration isnt the issue atlest not on my end

Please reboot it one more time, using the reboot button, and report here again on what is in the log.
