ATV2 "network card" failure under load

DiQ23 · 2012-01-24 18:41

Took it up to my office, different switch all gigabit with different cat 5e and it fails even faster now ! Pretty much proves it's the ATV2.

Fortunately I can get my data off via wireless. Fingers crosses that doesn't follow the ethernet.

Thanks for your help guys Smile

Go to an appstore ... i think they will exchange it instantly ... maybe restore it to a non jailbreaked version before Wink

I now have a replacement ATV2 and this one's doing the same !

Is it possible that it's a bug in iOS ?

Wow!

Well, I'm guessing the odds that a second ATV2 would have an Ethernet issue are fairly low, so since you eliminated the possibility of your network infrastructure at home being the culprit, I guess that only leaves the possibility of the file itself, or something about how you're handling the file.

Is it just that tarball and no other tarballs? How exactly are you transferring the file (command line, GUI, etc?). Need more details Smile

As for bug in IOS...have you tried this before jailbreaking?

Tarball changes - it's a backup of .../XBMC/... I've tried gzip and bzip2. I've also tried a VirtualBox .vdi file that I put on the ATV2 - same problem when copying off.

Same issue using WinSCP on Win7 both SFTP and SCP. Also using SFTP with Nautilus on Ubuntu 11.10.

Also SCP out of the ATV2 to the Ubuntu box. Also FTP out to my FTP NAS in binary mode (ascii makes the tarball unreadable).

All work fine over wireless but not wired. Moving files to the ATV2 is never a problem.

How would I try before jailbreaking ? I know how to un-jailbreak (did that this morning before returning it) but how would I transfer files from the ATV2 to wherever ? I used SeasonPass to jailbreak.

:confused2:

Duh, sorry, my bad. Forgot you can't xfer before JB.

Is it possible there's some kind of network configuration problem that exists both at your house and at your office where you tested? Jumbo frames or something? Grasping at straws here....

DiQ23 · 2012-01-26 23:45

My office and house are the same place.

I have three switches, all routers routers but only one has DHCP daemon etc running , connected together with homeplugs. The atv2 and the NAS are on the same switch. My office runs on another switch which is where I did the test.

I suppose I could try unplugging the the office switch from the network, giving the atv2 and another machine fixed IPs and try that. Can I miss out the switch with cat 5e and connect directly ?

I'll give this a go but the fact that there's no issue over wireless (g) makes me think it's not related. I regularly transfer much larger files than these ~800Mb tarballs about using ftp, sftp and smb with no problems. Still, I'll try.

Isn't there anyway to get logs from the iOS networking ? I mostly use Linux, the Win7 is for supporting MS products and games only. I've always found that in Linux it's quite easy to get to the bottom of such issues.

Sounds like a electrical ground problem imho. Either your ethernet cable has connected ground (which shouldn't be) or there is some sort of problem with that homeplugs. Whatever it is - i bet logs wouldn't help you here. Beside that there is no possibility for debugging ios networking on os level. You can only sniff traffic with wireshark or so - but i bet this will just show a broken transfer.

Try to get a minimal setup where only atv2, 1 switch and the nas are connected to the same electrical circuit (and leaving other electrical devices off if they are connected there too). Something like that ...

Tried with two routers, both disconnected from the homeplugs and the rest of the network. One router running stock Belkin firmware and the other DDWRT. Separate ethernet cables each time, four in total. Belkin connected to Win7, DDWRT to Ubuntu.

Same problem with both setups.

Is there anyway to change between wired and wireless from cli ? Thinking I could just script it to backup using wireless and then switch back to wired.
