Q: can't connect iMac using wi fi

I had been connecting to the internet on my iMac via wi fi for a number of years.  Until today.  Can't seem to connect no matter what I do.  Strange thing is, my iPhone and iPad can both connect to my wi fi network just fine.  I'm using ethernet now, but would prefer to use wi fi (hate the cables, but yes, I think ethernet is faster).  How can I start from scratch and get my mac to forget all the wi fi info save on my mac.  I had played around with the settings and I think I messed up everything.

iMac (21.5-inch Mid 2011), Mac OS X (10.7.5)

    10.5, 10.6, 10.7 & 10.8…

     

    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

     

     

    10.5.x/10.6.x/10.7.x instructions...

     

    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

     

    The interface that connects to the Internet should be dragged to the top of the list.

     

    If using Wifi/Airport...

     

    Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

     

    For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

     

    208.67.222.222

    208.67.220.220

     

    (There may be better or faster DNS numbers in your area, but these should be a good test).

    Click OK.
