Tried a search and got a lot of good info on home networking but need some more help. Currently have a wireless adsl modem, desktop with wireless USB connection to modem, laptop with wireless card access to modem. Having a loft extension witha computer, questions are is a cat 5 cable run justified or will a HPNA be just as good. Cat 5 in theory 100Mbps and HPNA maybe 10(is that right). If mainly for internet access and occasional file sharing is the potential higher speed necessary. Worried that wireless may not recah from loft to modem which is on ground floor as laptop connection to modem is very poor and has short range whilst desktop is much stronger. Any help greatly appreciated. I presume i cam mix wirelss and wired connections together, my adsl modem also has a slot for ethernet connection Thanks for anticipated help.
