i have always had problems with my macbook and IP addresses. most of the time it works fine, but there are occasions i go somewhere and it will tell me it can't connect to the internet bc i have a self-assigned IP address or no IP address at all. right now i am in a hotel and cannot connect to hotel internet. i have a portable router from verizon i am using. the way i fixed it on my personal router was by creating a new location in network preferences, then renewing the DHCP so it will give me a new address. this method does not work however for the hotel router. it will not assign me a new IP address. the setting is "using DHCP", but no matter how many times i try to restart or create new locations it will not fix my IP address problem. even though i keep it on "using DHCP", i occasionally have this problem, which i don't understand bc i thought "using DHCP" will automatically assign me an IP address no matter what, but apparently not? is their a way i can fix this permanently so i don't have these problems in the future? how can i always have an IP address that works no matter what router I'm using?
