Which tablet are you using iPad, Android or Windows? You never said. Do you have Box.com, Dropbox or SkyDrive? You could download to those cloud storage and then slide load the files to the laptop.
Can you do this on your laptop:
Click on Start or the Orb
Or press flag key and R on the keyboard at the same time
type: cmd
type: ipconfig > mynet.txt

What do you see when you type yours.
Another thing we can do for you is make you use static IP address instead of doing a DHCP.
This way you would force the PC in question to use a certain address.
IPv4 Address. . . . . . . . . . . : 192.168.x.xx (type in the address from what you had)
Subnet Mask . . . . . . . . . . . : 255.255.255.0 (match this to what you have on your tablet)
Default Gateway . . . . . . . . . : 192.168.x.x (this is from your router IP address)
