Macbook Pro 15 2010 cannot connect to Wifi - also cannot do AHT

MacBook Pro - MacRumors Forums - forums.macrumors.com
My Macbook Pro 15 (2010 model) is unable to connect to my wifi network even though I am using the correct wifi password. I am using conventional 2.4GHz wifi. Also, when I try to do an AHT via internet recovery, it seems to connect to wifi then (not 100% sure though) but then gives and error code:

"apple.com/support -3403D"

Does anyone know what might be going on here?
