Mother-in-law has bought mac mini (we are both newbies) and install in bedroom. Unfortunately the wireless connection to downstairs routers is not strong and 'comes and goes'. As an alternative we install a home plug set up so she could have, in effect, a hard wired connection. This worked fine for a few months but now the mini just doesn't like the connection. It will stay up for about 4 hours but then go. I guess the ethernet signal is just not quite strong enough. I have tried all sorts of plugs upstairs - some sort of work but most show no signal at all. Downstairs it is a little better but her mini is upstairs! The thing is - if I plug my winXP into any plug upstairs I get a strong signal an can connect straight away. If I take the mini downstairs and plug straight into the router it is 100% and it has worked 100% upstairs -for some reason it does not like it now. (I'm guessing the old house wiring and oxidised connections give too much resistance to the signal). But the winXP laptop works anywhere(!). The sets are the same, not too to do. Local/DNS server 192.168.1.1, 255.255.255.0, automatic ethernet connection etc. It works but compared to the winXP laptop the mini appears to not like the incoming (via the home plugs) ethernet signal. Is this typical for a mac mini?
