Thanks Sandman. Did just that.

Change Sleep to "Never" or at least 2 hours in Energy saver prefs. Or, Uncheck "wake for network access" in net work prefs AND uncheck ITunesFIle Sharing in Itunes sharing prefs.

Problem is with Sleep when networked to devices over wifi. You can also buy the latest Apple Extreme or Airport router if you want to pay to fix problem

Howdy,

Turning Sleep to ``Never'' is NOT a fix but rather a way to avoid running into the problem which should get fixed.

Incidentally, I've unchecked ``wake for network access'' for about a week now and haven't had my Gen1 Time Capsule drop my Ethernet connection upon wake. But it'll take a while longer for me to start feeling comfortable. I'd just as soon not have to buy a Gen4 Time Capsule but...

Good Luck,

You can buy new stuff. Ever since Snow Leopard, Apple added a wake on demand program called Bonjour Sleep Proxy - cause these problems unless your devices are really new. If you're not networking a bunch of devices, you've found your solution with turning off wake for network access and never sleep - I just changed my sleep to just over two hours since I use my computer pretty often

If you're correct in your assessment of this issue and it's solution, then perhaps someone should consider this issue solved? Do you think it covers everyone with this issue?

Howdy,

Quite frankly I don't consider any of these suggestions as fixes. They are all work-arounds. I happen to not need ``wake for network access'' but there are others that do need that feature active. Apple never says that I need a late generation Time Capsule (or Airport Extreme, etc.) to use that feature so, until Apple says so it should work.

vallejogreg, howdy,

Those works arownd unofortunately do not apply for the MBA that will sleep anyway when the lid is closed. If I open the lid the annoying bug shows up again (and no you cant keep the MBA all the time open, that makes the full concept of an ultraportable pointless).

And regarding buying a new Airport is not realistic either. I use my devices with more than 10 wifi networks. I should ask most of Dutch goverment agencies, the train and the bus company to change their access points to an apple Airport Extreme, just because I had the stupid idea of buying a MBA lol 😟.

Actually, they Do say that. Just not very loudly. They say you need the latest firmware and 802.11n router, which is saying you have to buy their router because there's not alot of routers out there that meet that spec.

Point well taken. I think I read from apple that you can close the lid if you keep the machine plugged in and then you won't have this problem. Apple really over reached on this issue of Wake on Demand for network Access

Howdy,

Well, the Gen1 Time CApsule certainly satisfies those conditions. It's at software version 7.6.3 which came out a bit earlier this year so that condition is met too. So why have I been having a problem with my WIRED connection to the router; at least until I turned off ``wake for network access'' and I'm still waiting...

And most modern routers meet those specs as long as the user keeps the router software up to date.

Good Luck,

I believe that if you even if you are wired, if the router isnt 802.11n and Bonjour Sleep Proxy capable, you will have this problem of unable to connect to internet on wake up. MOst routers DO NOT meet those specs. Apple put this out as open source code but that doesn't mean it will be adopted

Howdy,

Are the requirements now shifting on me? I have a Gen1 Time Capsule with the latest Apple Router Software installed, version 7.6.3. It's 802.11n. How do you tell if it's also, the newly stated requirement, ``Bonjour Sleep Proxy capable?''

Good Luck,

OK you got me. I don't know the various generations of TIme capsule - and don't care. But I've read that dropping wifi is still possible. The problem people are complaining about is dropping WiFI then being unable to log back on without shutting off router and turning back on. The machine sees the network but can't log on. Should only happen if asleep. Maybe your issue is different.

I disagree that the problem is being connected to DEVICES over a wifi network

I still have a long lag when starting from sleep and the only wifi device I have is the mouse. Its a NETWORK issue for sure...as when I start back up, my computer has diconnected me from the network drives, stopped checking mail and lags to connect back to these things.

It HAS gotten better. It doesnt crash on wake from sleep...it just LAGS for sometimes two minutes
