I've been trying to get my chromecast to work on my Cisco 1142 router with no avail. I have had my chromecast connected to multiple networks but I can't seem to get it to work with my 1142. I've tried everything I can find. I've tried the 'no ip igmp snooping' command, and confirmed that it's disabled. I've tried 'no dot11 igmp snooping-helper' also. My chromecast says that it can connect to the network, but has no internet access. I'm stuck on what it could possibly be, any help would be greatly appreciated.
