I have managed to fix it. When i connected my macbook to the aero I noticed that the signal was only 1 bar instead of 6 so I went into the aero settings and first i changed the channel from 1 to 2 but that did not fix it then I changed from frequency from 20 to 20/40 this made it work perfect. I am not sure if the firmware update had changed the frequency on the aero of the wifi or not but at least it is working now and I hope if anyone has this problem may find some help in this post.
