Trying to updated a Cisco 4400 WLC through TFTPD, which is the tftp server Cisco says to use. I have all the software I need but it won't communicate. I have only one guess as to why. Cisco says the server and the WLC need to be on the same subnet. The WLC is on 192.168.99.100 and TFTP server is at 192.168.96.69. Would I need to have the server be on a .99.xxx address as well? Is that what it means by same subnet? I'm not much of a networking guy.
