[CALUG] Booting back to Linux

[Miguel Gonzalez]

Hi, 

 Have you tried to change MAC address in the linux machine so the IP address lease is different? You can spoof your MAC address in linux.

 Regards,

 Miguel

Byran,
Yes, I am using DHCP, but I am reserving the DHCP address for that particular MAC, so I always get the same ip-address. It was the quickest way to get simulated static ip-address than remove Network Manager and use the normal way of assigning the ip-address.

No, I am not using UPNP router (or I do not think I am using it). I have a Linksys E3500, wireless N router.

The DHCP is reserved using MAC address, so I always get assigned the same ip-address irrespective of which OS is running.

Also, please note that this started with Windows 8 and it worked very well with Windows 7. 

Router logs have nothing in them to suggest errors, so for now, my only solution is to unplug the router for few seconds and plug it back in.
