Hey guys/girls I have had a problem with the most current update to lion. 10.7.2 for some reason kills my wifi on my macbook pro. It will work, but when I take it to school (which has a portal) it will work at first, but after I put it to sleep to carry it to the next class it will never reconnect again. Same thing happens at my friends house who has comcast. It will constantly disconnect if I put it to sleep and then wake it up. I have looked on apples discussion boards and fooled around inside airport but nothing that is suggested works. So as of now I keep a backup of 10.7.1 on hand and have downgraded back to that. Does this happen for anybody else? Does anybody know of a fix for this? btw I have a macbook pro early 2010 13in 2.3ghz i5.
