I'm running Lion on my MBP version 10.7.5 and I can't connect to my friend's wifi. Every time I try to connect it reads a connection timeout. I can connect to every other wifi network I try but his. I can connect with my iPod and his entire family with their devices but not my MBP. I've read other forums and tried everything. I've done Ethernet and it works fine. I've set my network priority to wifi and even manually set his. I've done the custom location thing and all of that but no luck no matter what I do. I need help.
