After my last SMC reset, I've noticed my wifi doesn't seem it likes to connect. Sometime, it'll be great, connects, works great, no drops or anything. Suddently, after coming out of standby, the wifi doesn't want to connect. It finds the network, connects, but doesn't get the IP. At first, I thought it was a problem with the base router, but I can connect without any problems from my dad's iMac and other wifi products, it's just the macbook air. Is there anyway I can fix this without a full system restore?
