100% CPU Usage when downloading? N66U

[Dunksterp]

Hey guys,

I stumbled upon this forum because I've been googling the crap out of my issue but to no avail.

I have an N66U router that's been configured and operating fine for several years. Today, when I started a Steam download (on ethernet), as I have done 100s of times before, my wifi crapped out. After troubleshooting and diagnosing, I found my router was hitting 100% CPU usage. This has never happened before.

It appears to be happening on all downloads, from all sources, on wifi & ethernet. Steam, speedtest.net etc etc

I tried SSH onto the router to see what was using most CPU and it appears to be:

httpd -i br0 -these two mostly
ksoftirqd/0 -these two mostly
protect_srv

Can anyone shed any light into my this could have just started happening?

I have virgin media that's about 250Mb Down and 30 up, been this way for 3+ years.

Has my router basically eaten it and is on it's way out?

This is normal behaviour if your router doesn't have hardware acceleration enabled.

Go to Tools > System Information > Network and check the status of HW acceleration.

OK, in my testing I ended up doing a full factory reset. I was putting it off due to lots of stuff in port forwarding. Since then, my internet speed has shot up to 350Mb when doing a speed test, and it seems to only use 50% CPU. This is all really strange.

I was pretty certain HW acceleration was enabled.

Either way, I guess I might get a little longer out of this thing fingers crossed.
