      Re: SAGEM 2504n transmitting frequent Wakeup / Wakeon Lan packets to iPad?

      Thanks for all the replies so quick.

      I have tried today turning off both iTunes over Wi-Fi sync & turn off UPnP in the router, problem still there.

      The wakeup packet is still being seen in the system log every 30s. That App I found enables you to look at the system log is called 'System Status', I used the paid version, there is a lite version but not sure what is disabled in there. Shows lots of stuff on processes, network and memory usage. You can't kill any processes, but it is certainly useful for this kind of issue.

      I wouldn't say having to turn off Wi-Fi is a 'Solution' to this problem, it's a circumvention, a bit annoying, but better than losing your battery.

      Does anyone know how we can get Sky to check if this is a Sagem router firmware issue? I know the Sky firmware hides a lot of the parameters from you. You can save the router config, but you need a manual to explain all the setting and I can't find one online for the 2504n.

      Thanks again for the posts, good to know other folk have encountered this also.

      Forgot to say, I have turned off wireless sync in iTunes as a controlled test to see if I get any improvement as you have had and will report back later!

      Having said that, I've had wireless sync enabled since it became an option and it wasn't previously a problem.

      I'm still very suspicious that the 2504n Fibre router is the culprit because the problem first started on the day that I swapped the router when I got SFU. Nothing else has changed here since then. Working in IT as I do, I tend to be very sensitive to looking at "what's changed" as part of my standard troubleshooting process!

      Similar to me then, iPhone connects to a wireless N access point and Sky router is handling DHCP only (wireless is off).

      in that case you should find that if you have wireless sync off when you have your iPhone in standby mode it should disappear from the attached devices on the sky router. Also when you wake your iPhone you should see that the wireless for a second or two is disconnected. My iPad however does not do this, my iPad is the wireless only version however.

      That was how it was when I was using the Sky Netgear V1 router pre-SFU.

      Since getting the 2504n, the iPhone shows up on the router summary page and the attached devices list as cabled - and it even shows up when it is standby! It is in fact connected wirelessly to the WAP. The WAP has a static IP address. The WAP is a Devolo dLAN AV200 Wireless N, so it's connected to the router via power line ethernet. The 2504n router's wireless is off.

      Using the very nice System Status app (paid version), I can browse the system log on the iPhone which shows that it receives a wakeup packet about every 30 seconds. This is the same as the OP reported, but I think he is using the 2504n's wireless.

      I'm just using the standard Sky setup of Fibre modem connected to the Sagem2504n.

      That's interesting as my iPhone4 at ios 5.1.1 does not get the wakeup every 30s when on Wi-Fi, but the iPad does, how odd. Clearly something is triggering the router to do this, I think this has to be a firmware issue in the router as the 2504n is sending the wakeup packet. Or perhaps it is something in how ios 5.1.1 negotiates the connection that triggers something.

      I think this is one only Sky and/or Apple can resolve.

      Is there an official route to submit defects to either organisation?

      Agreed. My suspicion is the Sky router which is locked down tight. No idea about the official route to submit defects to Sky - I suspect there isn't one!

      Re: SAGEM 2504n transmitting frequent Wakeup / Wakeon Lan packets to iPad?

      Is there a setting in the iPad which allows you to turn off/on WOL? Most devices have this disabled by default, but the iPad may have it enabled. This would explain why the iPad seems to be the only device to suffer.

      No sign of any way to disable WOL on the iPhone (probably not on iPad either as I guess the UI is fairly common).

      Anyway I have trialled andrewjr's suggestion (turn off iTunes wi-fi sync) for the past 24 hours and I can confirm that this has stopped the rapid battery drain. Probably because it's no longer receiving wakeup packets every 30 seconds!

      I'm still puzzled about why this only started to happen since the day of changing the router from Sky Netgear V1 to the 2504n Fibre, hence my suspicion that router behaviour is the cause.

      The Netgear seemed to know when the iPhone was in standby and didn't list it as attached when it was in standby - the 2504n seems to keep sending wakeup packets every 30 seconds and always lists it as attached (even when it's in standby).
