I have about 15 devices connected to the router (some wired and some wireless). A few months ago, some of these devices started to randomly lose connection. When connection was lost, the IP address would change from the 192.168 string to the 10.0 string. Release and renew of the ip address worked in some instances but not in others. After setting up assigned ip addresses for each device did not help, I replaced the rotuer with a new Linksys EA3600. I am having the same issue on the new router and with different devices. I am even having the problem with wired devices. I have created a dhcp reservation for each device but it has not helped. After waking up a pc, after the lease expires, or sometimes just randomly, the IP address of the device will change to the 10.0 string and no longer be able to access the router and subsequently the internet. Release and renew rarely works. I have tried everything I can think of on various machines including rebooting the router, rebooting the machine, disable and enable nic, uninstall and reinstall nic and drivers, release/renew ip address, clear arp cache, and confirming tcip setting are set to dynamic.
I have had this issue of losing connection and the ip address changing from the 192.168 to the 10.0 with 2 different routers and several different devices and types ranging from ipads and phones to laptops, desktops and gaming systems. Different versions of windows are involved and though the problem has spanned 2 routers, the problem has not remained specific to a certain set of devices.
Any help would be appreciated.
