But I bet I could put the modem and my LAN on separate subnets to keep the DHCP servers from interfering with one another.

My modem is currently the only DHCP server on my network, and the router is set up to pass traffic through. Maybe you could help me understand something: You said it might have something to do with having the router in 'switch mode.' What do you mean by that, exactly? Is that when you turn the DHCP server off and allow the modem to assign the network's IP addresses, or something more complex? It'd be great if someone could figure this out!

I've just been leaving the iSpot's wifi on and connect the laptop directly to it to get around those annoying website hangs, but you're right about the range being too short. All my other devices that connect through the router are working great: Slingbox, Tivo, VOIP phone.

My feeling is these issues may be resolved if we can figure out how to set this up in regular router mode instead of switch mode.

I noticed this exact same behavior when connected through the router as well. 2) YouTube videos will sometimes buffer part of the way, then stop buffering until I manually advance the progress slider to the next 'section' and then it happily buffers that section before hanging again.
