MacBook Pro Can't find home wireless network

Thanks. I have fixed the problem. I just changed the router channel from 12 to 11. You're a genius!

Same problem, resolved by changing the channel. Hats off to the trouble shooting by you, sir portiao! Feels amazing to finally know why would my macbook air suddenly say "f**k you, yes, you particularly" to my home network.

The above works. The exact same problem - rMBP stops detecting the home WiFi network all of a sudden whereas all other devices - iPad/iPhone/Windows PC - are able to connect. Worst of all, rMBP detects the WiFi of all neighbours although I am not sure if it would have connected.

NVRAM/SMC reset didn't help. May be, they were not meant for this problem.

The one thing I had done prior to this problem that might have caused it is this - The rMBP was detecting & connecting to the home WiFi network although it was dropping the signal often which problem itself developed all of a sudden. I made the mistake of "forgetting the network", and it seemed to "forget" the whole thing.

Resetting the WiFi channel to 11 or < 11 helped. This was on Auto before that although the current channel was showing 2!! Can't understand but removing the Auto helped. All other devices, too, connect now.

Hopefully, good to go!

Oh Thank you so much ! Your Solution worked like a charm !

The fix worked, but just because it worked does not make it ok. Why in the world would apple design their software to only read a limited set of channels? And then i'm required to go into my wireless router settings and make changes there?

I'm a lifelong apple fanboy and this seems a bit ridiculous and a bug worth looking into. Its kind of embarrassing when a windows computer, my iPhone, and a samsung note all can connect to a wifi but my macbook PRO needs me to change the settings in my wireless router...

OK. This has happened to me a few times in a couple of years: (Model: MBP 2011)

Here's what worked for me:

Note: You can do this from another device that DOES connect to your home wifi (iPhone, PC, ..etc) or you can plug in your MBP to your router via an Ethernet cable.

1- Log in to your router configuration panel by typing 192.168.1.1 into your browser (The Username and password are usually supplied by ISP or manufacturer). You can google it as well.

2- Go into "Home Network" Section and then "Devices" Subsection. Click on Edit somewhere on your screen (Mine is on top right corner. I have a Thompson router). Delete the Wifi MAC address of your MBP. If you don't know which one it is or don't know what a MAC address is, delete all devices you see there. (don't worry, this is like tapping -forget this network on your iphone-)

3-Click Apply

4- Go into "Home Network" again. Look for "Channel" line. It should be on "Auto". Change it to a random channel like 3, 4, 5 ... Click Apply. Change it again to "Auto" click Apply again.

Your network should be detected right away by your MBP. If not, restart your router (turn off, unplug about 30 sec and plug back in, turn on).

This worked instantly for me.

Thank you so much! Glad that this support community exists, as the apple care people were not really able to help me.

Try setting a new location for the network. In System Prefs/Network in the Location window at the top, navigate to Edit Locations and a window will pop up where you can add a new location.

After that, go to Advanced>TCP/IP and renew the DHCP lease. Then Apply.

Thank you so much for this reply. This was driving me insane, It totally worked. The cable guy had set the WiFi modem to channel 13. I just put it on 7 and it started working. Thanks again.

Guys.. need your help...

i have try to set from channel 3 until 11 but nothing happen...

my MB still cannot detect my house wifi...

pleaseeeeeee..

help me....

Yes, this (changing modem channel settings from auto to a specific number <11) worked. I have been ignoring it for too long as when I restart my Mac, at times the problem solves or I end up using my iPhone portable hotspot in the interim. Today I decided to do what it takes, searched & came across your solution.

Thanks so much & God bless.

Of course, in my case, I had to call the helpline (1504 / 12540) of my ISP (MTNL Mumbai) who guided me step by step on changing the channel i.e. connect the LAN chord to a PC (which was detecting the connection), log in to 192.168.1.1 & then change the channel from auto to a specific number <11 (I selected Channel 1) under the Interface Setup > Wireless.

I'm having the exact same issue here, but before I change the channel on my router, I tried booting to windows.

Why does windows work and mac osx doesn't?

AWESOME!! For days I've been trying everything I could find about why Macbooks would drop signals...nothing worked...except this. Whew!

Thanks so much!! I had the same issue. I changed the channel to below 11 and it worked!! Thanks a bunch!
