network connection

using windows 7 and dlink 524.
8 months ago....went away from my home...everything working
just came back...reconnected everything..............can't open up my network upon my laptop (I am the master). (I can however pick up my neighbors network )
my wife can connect on her laptop and with her I-pad (in another room) on our network
my computer will connect on a direct modem to computer set-up but not on a wireless router connection
