This sounds like a similar problem to one i'm having - I started to notice it a couple of weeks ago when trying to watch some mkv files over the network. Normally they'd play fine but these were taking up to a minute to buffer enough to start playing…. I thought it may be the files themselves as normally I only play files I've ripped myself and these were ones I'd downloaded.
then I noticed that other files I know were ok were taking a long time to buffer on my ps3 too… even though that's wired into the same router as the MBWE.
I've tested the network and router and it's not them that's at fault…..
Also, the boot time is ridiculously slow now when it wasn't before…. takes nearly 10 mins before I can access the config web page and about 7-8 mins before I can SSH into it. but i can ping it successfully after about 4 mins.
On Saturday I went out and bought a 3tb external USB drive to back up all my data (mainly movie rips of my entire DVD collection in high quality - I'd cry if I lost them because they took me months to rip them)….. in all there's about 1.2 tb of data in around 2000 files.
I plugged the USB drive into the port on the MBWE and set off a copy - I've done one before on another drive when there was only about 1tb of data and it completed overnight.
This one didn't…. it's just completed about an hour ago…. so it has taken from saturday at about 4pm till wednesday 4pm to copy the data off it via USB. :-(
just done a hard reset to factory default and the problem is still there.
I'm not really aux fait with linux, but i've just used 'top' as recommended on another thread and there's nothing hogging cpu or memory that would look like the cause of the slowness.
I did install featurepack manager a while ago and I know it was definitely working OK before then, so i'm going to try and uninstall that now (i would have thought it would have disappeared with hard reset but didn't).
So, any thoughts anyone on what else I can try if uninstalling that doesn't work?
