MacBook Pro and wi-fi

Hi all,

I had to reset my wireless modem recently after a lightning strike zapped all my settings.

After setting it all up my MacBook Pro keeps asking me to reconnect to wifi whenever I open a browser or turn on the machine. I've set my home network as my preferred network and saved the password.

I did re-name my home wifi network (and deleted the old one).

Each time I'm asked to reconnect on the MacBook there's the option of a neighbour's network. It doesn't come up in the options when setting the preferred network in Advanced, so I can't delete it as an option.

After redoing the wifi settings on my iPhone (and my wife's iPhone), my iPad and a PC they work fine. Only my MacBook keeps asking to reconnect.

I'm using Lion OS X.

Any suggestions?
