LAN dropping connection large xfer, then can't see other boxes

- Win7 Ultimate
- Dlink DIR 655 router
- Windows Firewall only thing running
- device drivers look good

About 800GB transfer, it would occasionally drop connection, but looks like most (maybe all?) files were moved. Had to restart transfer a couple times. Left overnight.
Today can't connect at all. Did ipconfig/renew, rebooted, reset other box. Poked around

Other boxes can see my Win7 box, but Win7 can't see other boxes on LAN
