okay, i was having a problem with my surfing, using wifi, so i decide to reset the ip address using ipconfig in dos. once i did that, it wouldn't renew. at this point, my lan and my wifi would not connect. it would eventually time out and give the message limited connectivity. i disabled the wifi and was able to renew the lan connection but not the wifi, then i disable the lan and was able to renew the wifi, but not the lan. so right now, i have the lan working, but not the wifi. when i try to renew the wifi, it just hangs until it times out. so, how can i get both to work at the same time again?
