Why can't I connect to my house wifi?

Maybe you are having trouble with your CapLock key and entering the password in upper case😉

Else I might try:

1. Using an ethernet cable connection to check the internet works that way.

2. Deleting the entry for the network in System Preferences>Network>Advanced and starting again. Check you are entering the correct security type required by the ISP.

3. Wiifi diagnostics are available by holding the Opt key and clicking on the wifi icon in the toolbar. Then go to the Utility menu and select the Scan tab. If many of your neighbours use the same channel, you can go to your router and change your's to a different one etc.

Wifi problems seem to crop up a lot on here and unfortunately there doesn't seem to be a 'one fix' solution.

However, sometimes any one of the following may help although, unfortunately, not always. - in no particular order:

• Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
• Change the wifi channel on the router
• Create a new Network Location: http://support.apple.com/kb/HT5289
• Reboot the router

Also take a look at this link and the links within the article for other ideas. They mainly reference Lion, but still seem to be relevant to Mountain Lion:

Then you tried with an ethernet cable? If it cannot find the network this way, it is nothing to do with wifi. In System Preferences>Network, go to the Ethernet settings and check you are using DHCP and set the advanced options as per your other computers.

I couldn't get mine connected either, and when I was on this site trying to see if anything would work, nothing would work, so I clicked on System Preferences>Network>Assist me...>Diagnostics...

and then just followed all the steps, and now my Wi-Fi works! I hope this helps you if you haven't figured it out already, or helps someone in the future looking for an answer! 🙂

Hi, I'm experiencing the exact same problem as the original post but none of the suggested answers have worked for me. What was the solution in the end? Thanks

I had this exact same problem, too, and found the resolution buried in another thread: renewing the DHCP lease. It's described in step 6 of http://support.apple.com/kb/HT4628.

thanks Paul. I created a new location and it worked.

I just received the Newest Pace from AT&T and had the same issue attempting to connect to my home wifi. The password was correct so the problem was not there. My work around to was use my iPhone and generate a hotspot, I then connected my laptop to that hotspot. Once I was connected to the hotspot, I then connected to my home wifi and "Poof", Im connected and everything is running smooth. Don forget to turn off your hotspot on your phone. I had to do this with my youngest daughters old phone as well.

I am adding this here for a search result because I know that this problem has accrued many times already while speaking to the at&t rep and its gonna happen again.

It is a Pace 5268AC and I am working on a MacBook Pro with OS X Yosemite.

Hope this helps someone and have a great day.

I ran into the same issues with my Pace 5268AC from AT&T on my iMac / Mavericks OS. While connected by ethernet, I tried several of the suggestions listed above to no avail. After three hours of frustration, I randomly decided to change my Network Name to something more personal. Much like Martin's post above, "POOF", I'm connected by WiFi and everything is running smooth. I rebooted and still working just fine. OMG.

Below is a link for those who may not know how to change your Network name.

You need to type the IP address listed on the back of your router in the url window within your browser. Then go to WiFi - Modify security or settings.

After all was working, I then went back and changed my password. I didn't want to change too many things at once! : )
