Unfortunately it looks like my system is still struggling a bit.Hi John,
Thanks for this.
I did wonder about whether I'm just hitting the limit of the router but I believe I didn't see the same problems when using the merlin firmware.
I was also finding that, for example, loading websites on my laptop would take an incredibly long time when I'd already have a 4k stream running from my local server to my TV. The 4K video's bit rate was ~60Mbps so I figured the wireless 802 N router should be able to handle both things at the same time. Restarting the router would solve the problem (for a few hours).
By 'exact data', are there some logs I can extract from the router or were you asking for some more descriptions of the kind of things I'm seeing?
Basically, when I power on/boot up the router, I find that I am able to run multiple video streams from my local media server to our various devices (laptops/phones) and simultaneously browse the web. After about a day (sometimes less), I struggle to watch a single stream and browse the web at the same time. Restarting the router makes the problem go away. Sorry if this is still too vague...
One big thing I've tried today is formatting the JFFS partition (I'd missed that part from the instructions). So far today, everything seems to be pretty solid. Fingers crossed that this was the issue...
It felt like I was able to more consistently handle multiple HD streams without buffering but, towards the end of the day (5 mins ago), my system was unable to stream a single 4k video from my local media server (connected via ethernet to my rtn66u) to my TV (connected via wireless) without regular buffering. Restarting the router again resolved the problem.
One new clue is that, while my system is struggling to stream, I am unable to access the router via 192.168.1.1 (my webpage hangs). After restarting the router and attempting to stream again, I --am-- able to access router GUI while the stream is running (but the GUI is slow to load).
I don't know if this illuminates anything or not...
One other new clue: I've enabled ssh as I wanted to check `top` when the router was struggling. The ssh connection becomes unresponsive (I cannot make top update) when the stream is struggling. It's almost as if the 4k stream is overwhelming the router. Should streaming a 60Mbps movie do that to a rtn66u?
When the stream is struggling but top manages to update, it looks like ksoftirqd/0 is using up a lot of CPU time...
