My wifi connection stopped today. Connection timed out

Dylan_love,

I have had no luck solving the problem. I've moved the router and tried many of the suggestions I've found online with no luck. Don't know if it could be the computer, the router, or ? Seems odd that I can connect initially but then the connection gets dropped.

Have spent so much time working on it that I've given up for a while. Love to hear if you come up with a solution.

Sorry.

You can download iStumbler99 from here:

It will show you what other Routers of all types are around you, and what channels they are using.

More than one Router on a channel causes interference. More than two cause the channel (and usually two up and two down from it, as noted in my post above) to become unusable. If you cannot move your Router and computer to get a better signal, you will need to obtain a dual-channel Router.

Thank you Grant Mattox! I will definitely get back to you incase I find a solution to this!

Thanks your response Grant Bennet! I will try that out and I really hope it works.

Hey everyone, my WiFi suddenly won't connect to my MBP either (posting here via iPhone). Really ***** to find out how varied and common these problems are.

I'm trying to understand the thing about switching 'channels'.

If a channel has a lot of interference, shouldn't the OP have problems with their other WiFi devices? Or is it more about finding a channel less 'crowded'? It's also more difficult to understand when there's only 2-3 other devices at home that are connected at irregular periods. I don't think the malfunction could be any more surprising.

There are an incredible number of variables. Signal strength can vary in distances as short as a few feet, and different antenna designs in different devices can produce very different results for signal-to-noise ratio.

The first thing to get right is to reduce direct competition for the channel you are using (or use a different channel until you have little or no competition).

Once you are not fighting with your neighbors' Routers, you can move your Router and your computer around to get the strongest signal and not too much noise so that you can operate without issues. Trying to optimize placement without first reducing competition is an exercise in futility.

More subtle issues can come from moving much larger amounts of data through your computer than your other devices.

Interesting stuff. Well I just went down and turned the router off, waited, then powered back on until ready. I also adjusted the antenna to point straignt up instead of at an angle, and this all has seemed to work!

I thought maybe there would be a different number in the adresses if it had switched channels, no? I recorded the I.P. and the other two numbers and they're both identical before and after.

Thanks everybody for contributing.

Hi. I had similar problems and found a solution that worked for me:

My Mac Mini suddenly no longer could connect to the WiFi network (connection timeout). Rebooting and restarting the router did not work. I tried deleting the network from the network preferences but this also did not solve the problem.

Finally I tried opening the KeyChain tool and found that the router password was still there. I deleted it and then tried reconnecting to the WiFi network. This time I was asked for the password and, voila, I was back on the network :-)

I guess the keychain password entry somehow had been corrupted.

I was havving a lot of trouble with the connection timed out until I changed the name of my network to the identity of my apple airport extreme to the name given by the newtwork which is: Apple Network 00000f (identity assigned via Airport Extreme). I am so happy I tried this.

Hi,

I've been having the same issue with my MacBook Pro mid-2012 and I went through, deleted all of the previous locations and then accessed the keychain tool and removed passwords for the wi-fi I was trying to use and it has worked (fingers crossed it keeps up with this) thank you!

Yes , change the Channel of Wi-fi network will work. I had the same problem with my mc book Pro . Now problem resolved
