I think this answers your IP question:
set IP address and config to default 10.0.0.1
Try setting up your laptop with a 10.0.0.x address...
I found a website that confirms this:
https://support.soundenterprises.net/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=28&nav=0,7"The PC on which your TFTP server software runs must be configured with a static IP address in the range of 10.0.0.2 to 10.0.0.30."
