|I missed the bit about running over power lines. I agree with wanderer 100% on this not being a very good method.|
I also don't care much for wireless. I highly recommend connecting via a network cable to the switch and then trying the transfer as wanderer suggested. Report back to us and let us know how it goes.
I dont have a cross-over cable but i did read somewhere that modern NIC can auto determine a cross-over cable setup and use any cat 5 as a cross over. Is this true, will it work?
No, this won't work. You have to use an actual crossover cable. Try connecting to a router directly and if you still get slow speeds, look into borrowing, or buying, a crossover cable and use it. Before you do, ensure all NIC's are set to autonegotiate.
