Cable from master socket to router, and router placement

[julianhj]

I have a few router-related questions:

- are telephone cables all pretty much the same in terms of quality, or can they have an effect on broadbands speeds?

- is there a recommended maximum length before signal quality begins to drop?

- are there any guidelines for the ideal placement of a router to maximise it's wireless strength?

Thanks!

Cheers, I've got a collection of cables to sort through, I'll try and pick the chunkiest looking one to connect my router to the wall.
