When both comps were using WIN XP then there was file sharing. Presently the problem is I have a "connected" XP comp and a "no network access" WIN7 comp.
I was told you can only have one network enabled at any one time per computer. Hence I normally disable the internet connection before enabling the network to the 2nd comp. This allowed me to use my one jack router connecting to the internet. I would then disable internet and enable the network to send my work compter any files I might have downloaded. Does bridging allow two networks to function simultaneously?
