My cable service comes into the bottom SW corner of the house. I have a Linksys WRT4g - v1.1! - trying to punch upstairs to the NE corner of the house where the office is, at around a 60 degree angle. It has to traverse magazine, classic NZ walls (made with WOOD and covered in Gibboard), and Rimu flooring. Total elapsed distance on the longside of a triangle is about 15 metres.
Suffice to say my experience is somewhat restrained.
I'm thinking of using 2 802.11n Apple Airports - I like apple kit - and bridging them, with the computers upstairs connected via wires.
Local reticulation on the 1st floor would be 802.11b/g, which is what my computers and smartphones have.
I'd appreciate people's thoughts.
I can't move the access point higher up, because the ethernet cable would then sit right next to 230v power wiring - unless there is cable shielded in lead these days ...?
