Something is wrong.

Usually a router's CPU utilization is 0% when there is not much network activity going on.

This is a snapshot of my Huawei WS880 dual-CPU utilization just now.

I have never seen it exceed 15% per CPU, even under heavy torrenting and video streaming.

Like I said earlier, "something is wrong".

I agree with what you say.

No use.

Every Tom, Dick and Harry in the neighbourhood who knows also use channels 1, 6 and 11.

The DD-WRT firmware for the C1200 is not available yet.

See here for the list of TP-Link supported devices.

Really?

Where did he get it from?

True.

It is really hard to get my Huawei WS880 to work above 20% utilization.

And I have 12 devices connected simultaneously.

True. With the FCC lockdown, you will not see the TP-Link's new model Archer C1200 running DD-WRT.

Here is an extract of the news....

"Last month, Libre Planet—a free software community—raised the alarm that TP-Link, one of the largest router manufacturers, had begun locking down firmware in newly released routers.
As proof, Libre Planet pointed to a transcript of a support conversation.

In the chat, a TP-Link rep says that the lockdown—which blocks the installation of open source firmware—was a reaction to new FCC requirements.

That’s a problem, because alternative router software packages like DD-WRT are hugely popular. These tools provide more sophisticated features and faster security patches than manufacturers offer.

I contacted TP-Link and asked them to confirm whether their support chat rep was correct. The company directed us to a new FAQ page confirming the lockdown. The FAQ reads,

Why is TP-LINK limiting the functionality of its routers?

TP-LINK is complying with new FCC regulations that require manufacturers to prevent certain firmware customizations on wireless routers.”
