I applied the solution and it seemed it worked for a while but the problem occurred again.

I looked at the problem suggested by Gary that it has to do with the country code. I live now in Germany. I checked the setup of my Time Capsule and apparently the signal from there was with UK CC. I changed this setup to Germany and since then all goes smoothly.

Actually I have an impression it goes faster!!!

So check first the setup of your router.

Cheers!

This fix worked for me on our iMac, finally! I have tried each of the fixes that osxdaily has suggested and none have worked until this one.
The WiFi connection would drop out after a certain period of not being used, then when we come back and try to reuse the iMac, after searching for WiFi signals it would latch onto an unlocked neighbors signal.

Thanks so much for your help!

Any thoughts on percipient wi-fi connection problems on iPad? Second Generation? Sometimes even making a hot spot with my iPhone 4 doesn’t result in actual internet access on my iPad. Not the end of the world but frustrating.

So far so good. No Wifi problems to speak of over the past few days. MBP connects to Airport Extreme and other routers with no need to reboot.

I’v never experienced any WI-FI connection / dropping problems with Mountain Lion until I recently moved (2,000 miles) I’m using the same Modem & router but a slower internet connection ( 10Mbps down to 3Mbps) due to cost. Now I get dropped at least once a day. Would any of these suggestion from this article or the article from August 2 address my problem, or would it be a internet provider (Time Warner Cable) issue ?

Be aware; if you use Rowmote. The app will not recognise you computer as is use to. You’ll have to name you computer again. In /system preferences/ network / share. Just name you computer as it use to be namned. Done and ready to go!

Martin, That reminds me. I had an issue with my home wifi connection that was caused by duplicate keychains. I could connect to my network but overtime would get disconnected. I tried the preferences to no avail. The problem has not occurred since removing the duplicate wifi network system and login keychains.

what to do to the files copied to desktop then?

I have been suffering from WIFI re-connection problems when waking my MacBook Air running both Lion and Mountain Lion, but I have finally worked out what has been causing the problem.

I suspect that many people who live in built up areas with many wireless networks around them may also be suffering from this too.

The problem is 802.11d – when your WIFI wakes from sleep the first thing it does is to listen for a wireless network beacon signal to determine what country it is in and then it restricts it WIFI radio to _only_ listen on the frequencies for the country detected.

Hence, if you have a neighbour with a wrongly configured country code then your machine will only listen on the frequencies for that country. I live in the UK and have a neighbour with a WIFI router wrongly configured for TW (Taiwan) – My Macbook then cannot see my Wireless N network as the channel is not one used in TW.

I suggest checking the WIFI network country codes in your vicinity to see if you might be suffering from this using the WIFI Scanner built into Mountain Lion: http://osxdaily.com/2012/07/31/wi-fi-scanner-mac-os-x-mountain-lion/

You can also check your syslog to see if it is configuring your WIFI radio for the wrong country:

Nov 9 18:18:11 GarysMacBook kernel[0] : en0: 802.11d country code set to ‘TW’.
Nov 9 18:18:11 GarysMacBook kernel[0] : en0: Supported channels 1 2 3 4 5 6 7 8 9 10 11 56 60 64 100 104 108 112 116 120 124 128 132 136 140 149 153 157 161 165

My wireless N network is on Channel 48 and hence not seen – hence the failure to connect.

The trouble is, I have put a letter out to all my neighbours explaining the problem and how they can fix it, but the WIFI router is still wrongly configured. I don’t know who owns the router as I have about 20 WIFI networks around me – about 10% of the time my WIFI still won’t connect to my WIFI network as it sees the TW WIFI Beacon before mine.

I think that the 802.11d spec needs changing so that the country is not set on the first WIFI radio beacon detected as this can be wrongly configured. The strange thing is, I only see this behavour on my MacBook and not my iPhone 5 or my Windows laptop, so it must be possible to work around the spec.

Maybe I can report my neighbour to OFCOM regulator in the UK, but I can’t see much hope in this.

At least I know the problem, if I can’t fix it.

I hope this helps some people as it was bugging the hell out of me.
