Q: My Mac Pro won't connect to Wifi?

My Mac Pro won't connect to the Wifi that it has been for the past 2+ years. All other devices in our home that use the same Wifi are working just fine.

MacBook Pro (13-inch Early 2011)

A:

Tried doing Network Diagnostics multiple times, did not work. Keeps saying it can't connect or times out.

 

What color was the light pertaining to Wifi in the left column?  Red, Green, or Yellowish/Orange?

 

Some of the following you may have already tried:

Try the basics first:

   Change your router channel number.  Most times this works & is all you have to do.

 

Disconnect & reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.

 

System Preferences>Network

Click the Assist Me button.

In the next window that pops up, click the Diagnostic button & do the necessary.

    Care to share which OS you are using?

     

    Please detail ALL you have done so far in the way of troubleshooting?   Need this info to avoid the been there done that scenarios.

    I'm using OS X. Version 10.7.5. I've unplugged the modem to reset it. Tried doing Network Diagnostics multiple times, did not work. Keeps saying it can't connect or times out.  Besides restarting multiple times and turning Wifi off and on again, not sure what else to do.

    My daughter is having exactly the same problem with her Mac Book Pro (which is the same model as yours)  Did you sort this out? I can't really tell from this thread. Anu suggestions greatly appreciated.

     

    Thanks
