Two Issues with _5 on N66R

[Zhenya]

Hi All,
I made the jump from my old WRT54g a month ago and am loving the N66.

I have 2 issues with the newest build and was wondering if anyone had the same issues / had a fix

• Core CPU 100% - The cpu seems to be almost continually pegged @ 100% according to the Network Map - System Status
• When I am downloading large amount of data, sometimes,the download speed seems to be almost be a step function. Data moves (at any given speed, usually slow) then a step function to zero and then back to some other random speed.

Has anyone seen any issues like this? What logs can I provide to help understand this better.

Additional information - I have 2 drives attached. 1 is an externally powered 1.5 TB non solid state disk drive and the other is a 1gig usb stick

Thanks!

Let me guess, you're using the inbuilt mediaserver? (minidlna?), that will go bonkers on transmission and USB-HDD activity and rise either itself or the other conflicting proccess to 100%.

Try to open ssh and run "top" to see whats going on with what in realtime.

If using minidlna, try disabling it and see if that helps, and if it does, you should use the entware version of minidlna instead, I've gone from constantly/daily 100% CPU to now having barely over 1%, sometimes peaking at 10-12% when doing heavy load on USB-HDD+transmission+minidlna.

If you don't like the penguin Icon in the minidlna that comes with entware you have the entware-version of minidlna with the regular routericon: http://forums.smallnetbuilder.com/showthread.php?t=21981

You nailed it. I turned off ' DLNA Media Server'

in

USB Application -> Media Services and Servers ->Enable DLNA Media Server

That eventually brought down my CPU usage to a respectable 3% while streaming an HD video (with small spikes of 18-22% on load or other actions)

I mistakenly thought that DNLA had to be enabled to get the SAMBA server to work. Since I am using SAMBA, I don't are much for the DNLA fix (hopefully Merlin will roll it into the upcoming build)

Thank you!

Glad to be of service.

I really like samba better too, it doesnt depend on databases and you can set security/password, while DLNA is just a plain "dumb" protocol, with no security/parent control and bases itself on database-structures / constant updating.

On the other hand, if you plan on using the router to watch movies on a smart-TV etc, you will eventually have to use DLNA, since they most likely wont support smb/samba/cifs/nfs.

In a "perfect" world I wish all the smart-TV companies started supporting smb/samba with password security and automatic thumnail-fetch of jpgs with the same name as the video-file, it would be so much easier, alot safer with good parental control and alot less strain on any router. DLNA is a "joke", but the TV/media-industry has made it a requirement, the DLNA-makers probarbly had this guy on the sales-team: https://www.youtube.com/watch?v=OaiSHcHM0PA

SAMBA works great with the following setup, even with a USB 2 external drive streaming 1080p video (and other devices cruising the web)

N66+EXTHD_USB2 -> Nexus Player -> Kodi (app)


Nexus Player

Kodi Tv (XBMC) This recognized SAMBA and loads everything beautifully.
