wifi signal lost by macs upon sleep
Posted by: MartyStickle
Date: August 09, 2012 05:17PM
Recently moved and set up our networks as follows: Cable Phone/Internet modem to Apple Extreme. Ethernet wired to Apple TV and wifi connection to 3 macs, 2 iMacs and 1 MBA. The computers lose the connection to the wifi upon sleeping and so each time we come back to our computers, we have to select the router all over again. Shouldn't this just happen by itself?

Using 10.8 (just upgraded) but I think it also happened in Lion.

I'm still having this all the time in Lion and in Snow Lepoard. Usually just turning Airport off and back on gets it going.
Have not been able to solve it. (Asus router here.)

remove all WiFi entries for that particular router, do this in network preferences, and also in keychain (and look in all keychains, login and system). Most of the time this solves the issue.

It could be a router issue as well. Try it with an Apple router.

Sorry, I don't understand this. Do you mean from Airport Utility or in Network Settings? If the latter, I don't see any wifi entries??

Missed that. Saw Asus. Is the firmware up to date on the Extreme?

System Preferences -> Network, click on Airport, then on Advanced, again on Airport tab, and under Preferred Networks. remove all entries (click on MINUS sign)

Chris,

When checking Airport utility, I note I have "check for updates when opening" checked. No updates were listed. Is that what you mean?

OK. There was one network there and it was an unsecured network I used to use when I lived on top of a mountain without neighbors. I secured the network now that I'm in civilization. Anyway, i deleted that network and we'll see what happens now.

Thanks.

the airport utility should warn you if a new firmware is available.

You can also click on the word "version" and a menu should open which will list several version availabe for upload. make sure you have the latest.

also, try to restart the Airport once in a while.

OK Thanks ST. Of course it's only been running for a couple of days. We'll see if the deletion of that network helps.

to make it clear: I would delete ALL network, both from that panel and also form Keychain. Then connect again (you need to enter the password).

Update: Seems to have helped. After waking up, just about 5 seconds the network comes back. I'm happy. Thanks ST and Chris.

Yep. Multiple routers, Macs, and across OS versions. Doesn't happen every time, but it will occur in spurts. Toggling Airport on and off generally solves the problem.

Huh? What does "yep" mean-- that you have the same problem?

My new router installation didn't give me a Secure network (lock by network name) How do I get a lock (secure) network now?

Yes. It doesn't happen all the time, but often enough for me to make note. In fact, I have more trouble with WiFi on my Apple devices than all other devices combined. I have a lot of Apple devices so maybe the comparison is unfair, even still, it gets annoying.

Yes, Sam needs to go in to her router and configure for security. WPA2 personal with a long 30+ character password ideally. While poking around, check the channel used. 1, 6, or 11 are the best options for 2.4 GHz, while 5 GHz has more room to avoid overlap and a completely different set of channel options. Also disable WAN access to your router if enabled.
