Need to connect to a wireless network 320' away

Hi,

The house next door has a high speed cable connection. I'm looking to try to connect to it either wirelessly or via a direct wired ethernet. The wireless router is about 320' away from my wireless access point at my house. My connection is very weak and sporadic at best. There are a few trees in the path but not a lot.

I would like a solid/hassle free connection.

I've been looking at either a direct burial cat5 cable, will these work at 320' away?

Or somehow extend the range so that I can reach 320'. I was looking at possibly purchasing a couple of Hawking's Outdoor 14dbI directional antennas.

Whats the most solid connection to reasonable cost solution for this situation?

Any and all replies greatly appreciated.
