Wifi issue - Sleep/resume when Time Machine is active results in lost connection

I also have this same problem. Macbook Pro with a Time Capsule backing up over wifi. Whenever I put my machine to sleep (close the lid) while the Time Machine is backing up, I can't get back online til the Time Machine times out. I usually restart my machine at that point.

For the time being I just stop the backup before I put it to sleep.

Annoying!

I am having the wifi, sleep, TM problem also. How do I notify Apple that this problem is widespread? I am running Lion 10.7.1 on an Early 2011 15" Macbook Pro.

Same problem here. Actually I've had some problems even on Snow Leopard. Time Capsule disk wouldn't mount - that would happen every 2 weeks or so, it would backup but after restart (although wifi worked).

Otherwise I am having the same behaviour on Lion. Mid 2010 MBpro 13" (also happening on late 2010 MBAir 11").

I just bought a time capsule and I have a Mac Book Air (the verson without the back light keyboard). I am having the same issue. I also have the latest verson of Lion. A friend of mine has the newer Air and a time capsule and is NOT having the same issue. Also I think he may have a diffrent wifi radio in his because when he is within 5 feet of his Time Capsule he gets 25 megs a seccond of data. I can't get that from mine.

Hopefully it gets fixed soon.

Like others it only will happen if my mac goes to sleep.

I have had the same issue since I updated my 15" MBP to Lion - same deal, from time to time when I open my laptop, the Wifi is non-functional for about 1-2 minutes until time machine backup times out. Then Wifi reconnects

This seams to only be a problem when using a TimeCapsule. I am now backing up from a Macbook Air to a shared folder on a Mac Mini with no problems.

No, the issue is there when backing up to Mac Mini as well - at least for me. I'm running a 2011 Mac Mini (also with Lion) as my file server.

Note that the backup itself is not a problem. It is when you put your computer to sleep during the backup and then try to wake it up that the problem will show.

This problem did not exist in Snow Leopard. I wish I could go back! This is VERY frustrating and NO response from Apple!

happening here too.

I get this issue when TM backing up over WiFi to my NAS. I've got in the habit of checking that TM isn't running before closing the lid. Then it works fine.

I have the same problem. Since upgrading to Lion, when I reawaken my Macbook Pro, and Time Machine is running--and it always seems to be running--I have to wait 1-2 minutes for Time Machine Backup to time out, then wifi reconnects.

The suggestions seem to be:

- force quit / relaunch Finder

- or notice if TM is running before suspending

- or wait for Apple to fix it, which they haven't in the past month

Same problem with a MacBook Late 2008 and a 1TB Time Capsule.

I have to wait to Time Capsule finish the backup and eject the disk, or stop it manually.

My MB uses the 5 GHz wifi of the Time Capsule, and I have also activated the 2,4 GHz, with different name, to use with other devices like ipod.

Has anyone tryed to conetc the MB to 2,4 GHz and see if the problem continues?

Now I'm at work. But when I get home I'll check.

If Apple does not correct this in the next update (10.7.2), I am thinking to go back to Snow Leopard.

Thanks at all.

I've noticed that this is very intermittent. Time machine works overtime on my system, gigabytes of new stuff, it's busy all the time but I noticed that it doesn't always hang on re-awake if TM is running. When it hangs, TM is always running but often it'll awake with TM running and the WiFi will be running just fine.

I can't be sure about this, I've only tried it half a dozen times but I think it only hangs if you power down then power up with the charging lead plugged in. So far, if I shut the lid with the lead out, it wakes up just fine.

Like I said, I'm not 100% sure but so far it seems to be working. I thought I'd mention it anyway, see if others found the same thing.

Same problem here with new MacBook Air running Lion. Just switched out my Netgear dual-band with Time Capsule and this morning when waking the system from sleep, which occured in the middle of a time machine backup, I couldn't see the Time Capsule on the network. After some fiddling I'm re-connected but get the continuous "Wi-Fi Searching..." radar icon.

This appears to be fixed in the 10.7.2 release.
