WiFi Connectivity bug in mavericks?

Hi All, This is not a VoiceOver issue at all; my Mac is doing something annoying and I want to see if anyone else is having the same problem. I have a 2011 MacBook Air running 10.9.2. When I wake my Mac from sleep, the Wifi status is "No signal." This happens no matter if I've physically moved the Mac around from network to network; it occurs both when I venture out and when the Mac is sitting at home. Turning Wifi on and off again does not resolve the problem; the only workaround I've found is to restart the mac. Granted, a Mac restart is a far cry from a windows restart on an actual hard drive, but I just wanted to see if any other 2011 MBA owners had seen this to determine whether it is a software, firmware, or hardware issue. It seems to happen every other time or so that I wake my mac. Thanks, Chelsea
Not as of yet. No issues here. I'm drawing a blank, but if there is a way, try reseting yrou network settings in maverick and that should clear out something corrupt if any.
Take care and hope that sort of helps.
OK, I'm not totally sure that it's an issue with going to sleep, as I run No Sleep Helper, plus my mac mini, I tell not to sleep ever, so, yeah, but, I have noticed as well this issue. I'll leave the mac running, not necessarily asleep, but just in general, and won't touch it for about a day or so, maybe half a day at very least, then will come back, and the wifi has dropped to no signal. It's the strangest thing! I'm not where the range of my router would be spiratic either. I have a Linksys WRT54S router, with the most recent official firmware. I didn't hack it or flash anything weird on it. The weird thing is, this is happenning with my mac mini, my mom's mac mini, which both are the late 2012 I5 500GB drive, 4GB ram systems, although my mini, I upgraded to 8GB, but anyway... It's also happening on my aluminum mid 2013 non-retina display 13 inch Macbook Pro with 4gb ram, I5, 500GB hard disk. None of the drives are SSD's, although I'd not think that would matter. I've not had to restart the mac like you clame though. I can usually just go to my menu extras with ctrl+F8, vo+right arrow over to my wifi no signal, vo+space on it, then vo+down arrow, and vo+space on my network, then it reconnects just fine. Yes, I have reset the router. Yes, I've power cycled the modem. I'm a certified network administrator, and have been since 2001, so I think, frankly, I'd know to do that. I'm not that far gone! I've checked to see it there might be an IP internal Lan conflict, and there isn't. I've looked at the router's DHCP settings and server, and they all look perfectly good. I don't see any ports which are conflicting, and no TCP/UDP port triggers causing the issue. I moved from channel 6 which is common, to a more non-common wifi channel, and that did no good. None of my other wifi devices have this problem. Not even my white mid 2010 polly-carbon 13 inch macbook with 2gb ram, 250GB hard disk, not sure the processor. It's whatever came standard in those base units when non-customized. Even that system isn't having the problem. My friend has brought over her macbook Pro, and her macbook air, and neither of these ever have had this issue. My friend who often comes to visit me always brings his macbook which is identically the same model as my white polly-carbon macbook, and he never has the issue either at his home, nor at mine. It seems to only be my mac mini, and my macbook pro having these issues. All of the macs in my home on our network are running OSX Mavericks 10.9.2. So, yeah, bottom line is, you're not crazy. I guess neither am I, huh!
I have experienced this problem too with my mac and my iDevice both devices would just disconnect from the network with out me doing any thing all I would have to do is reconnect them to the network then they are working fine.
Reconnecting to the network manually worked; much easier than restarting. So it looks like a Mavericks bug, unless your MacBook models are running Mavericks as well. Thanks!
I encountered the same problem when I upgraded to 10.9.2. I did a search on Google and found an article that linked the issue to Bluetooth. I turned off my Bluetooth and the problem disappeared. I don't know why this worked. When I want to use a Bluetooth device, I simply turn it back on. When the problem did occur for me, I did not have to re-start my computer but just re-connected the WiFi. I read that the problem may only be present with certain routers, particularly Airplane routers. Hope this helps.
Hi Wayne, I actually use Bluetooth very rarely on my mac and didn't realize it was turned on. Apple seems to have a habit of enabling it on update, so thanks for the tip. I'll see if the problem goes away.
