I noticed Load average: 4.99 5.02 5.00 on the router
Quite unusual. Especially there is no one on the network.

So I made a top command and got the following.
Any clue? Thanks

R7000 on Firmware: DD-WRT v3.0-r33986 std (12/04/17)

Code:

Mem: 49320K used, 205268K free, 0K shrd, 5296K buff, 14492K cached
CPU: 99.8% usr  0.0% sys  0.0% nic  0.0% idle  0.0% io  0.0% irq  0.1% sirq
Load average: 4.99 5.02 5.00 6/140 20478

Thanks. But from the Reading Kong said it was fixed in November. My build seems newer.

not sure from your links if this is fixed or not, and not so clear as to what needs to be done.

Thanks for your followup.

It is fixed in Kong's builds, so use builds from him:
http://www.desipro.de/ddwrt/K3-AC-Arm/TEST/
reset to defaults by doing: "erase nvram" from the command prompt after uploading the new build
