My MacBook Air keeps dropping wifi connection on my home network. When I connect to my network, it remains connected for a few minutes, then it drops the connection. I have no idea what's the problem. I found several forums on the internet discussing this, but none of them really gave a working solution. My MacBook is 13" 2012 base model (MacBookAir5,2), I'm running the latest developer version of OS X Yosemite as of October 14th 2014 (GM 3.0 I believe), and my router is a TP-Link TL-WR741ND. These are the things that I found on the internet, and I tried all of them:
- Upgrading the router to latest firmware, resetting it
- Changing the WPA2-PSK mode to AES
- Set a different channel on the router
- Deleting the network information as well as related keychain items, repair permissions in Disk Utility, restart, reenter password for network
- Simply turning off/on the wifi on my computer
- I set the permissions of the Keychain items for my network so that every app can access it
- Swap the router for a different one (exact same kind, I have two of them)
All this with no luck. My MacBook still drops wifi every couple of minutes. I have been using the same router for months now, and I never had a single problem with it. This only started recently. I wonder if it's something in the latest version of Yosemite? I have been regularly updating to the latest version of it since the first developer beta came out this summer.
So what else can I do? It's very frustrating. This is the only network that my MacBook can't handle, and this is also the only device on the network that does this. Every other network is fine on my MacBook, and every other device on this network is fine as well.
1Option-click on the Wi-Fi Menu Extra and select Wi-Fi Diagnostics. What does it tell you? Use it to enable extra logging and keep it on until the next drop. What do the logs say? – Spiff – 2014-10-14T23:01:04.250
1This is strange: it doesn't seem to drop the connection anymore. The problem somehow magically disappeared now. I don't like these kinds of problems though, they can magically appear again... Anyway, I will enable logging whenever it drops again. – adam10603 – 2014-10-15T04:56:53.473
