I have also spent some time today in town and bought a telephone extension kit and also a wireless router and a couple of wireless USB sticks. I have ADSL and an ADSL router already. This is downstairs at the moment and I have cat V cables running from its location upstairs to my office. The plan is to move the ADSL router upstairs, extend the phone line upstairs and to leave all my SUN, HP, Linux and Windows boxes hardwired with cat V networking and to then have the wireless router so that I can use my laptop downstairs when needed and still access the net. Its taken me sometime to decide to go the wireless route but I have to get rid of the networking cables from downstairs and keep all the routers, hubs, computers etc in my office. Wireless is a neat solution for this and as there are security concerns with wireless it will be secured behind its own firewall and also the wireless will be secured and it wont be on 24/7, in fact it will be on when needed only.
OK, xmas lights to wire up now!!
