hmmm. my ISP is telewest / Blueyonder. the router is less than a metre away so im wondering if its worth it
That is who I am with. It really depends on the speed of your internet connection - for 2mb, I would go with wireless. 4mb...wireless again. 10mb, definitely wired.
If you are moving lots of files or large files from computer to computer across the network, use wired for sure. Just much faster and reliable.
