Wifi inactive upon wake, have to turn WiFi on and off.

Hi,

Every time my Macbook goes to sleep and wakes up, the Wifi is no longer connected, despite reports to the contrary in the menubar. I have to quit and then relaunch wifi from the menubar. This does not always work, however. And when it does work I have to wait a number of seconds – I usually can tell by my mail notifier which connects and notifies via Growl.

This started happening after I upgraded to Lion.

I have tried resetting the SMC and it made no difference. Any suggestions?

I suspect a disc wipe and reinstall would do the trick, but would really prefer an easier solution.

Thank you for your time.

MacBook, Mac OS X (10.7), wifi, lion, 10.7, wake, sleep

Quick reply:

Create new network location.

Delete the old ones.

Power down modem, router , Mac for a minimum of 60 seconds

Power back on starting with the modem.

SMC / PRAM etc will have no effect on this particular problem.

I have tried both of those (not in that order, incidentally) and it makes no difference.

I would be suprised if it had something to do with the router as I can connect happily with all other wireless devices.

In desperation I wiped the HDD and reinstalled Lion from scratch using the rescue partition.

Sadly this has not fixed the issue. Could it be a firmware issue for the particular WiFi card?

Looked this up:

Card Type: AirPort Extreme (0x14E4, 0x88)

Firmware Version: Broadcom BCM43xx 1.0 (5.10.131.36.11)

Any help gratefully received. This is driving me slightly nuts.

Well, it seems to work sometimes now. But even when it does (about 50:50 I think), I have to wait either because it really isn't connected or because I'm waiting for it to confirm via my mail checker.

I'm assuming this is a different issue to the WiFi not working at all threads.
