If I build an LMCE box, I will have to connect it to my network via a Wireless Nic. My router has a speed of 54MB while wireless (I havent tried it before though)
If I get a 54MB wireless nic, will that be fast enough to watch movies that are stored on my main computer on a windows shared drive?
Well I have not tried that exact configuration but my home lmce box has a Linksys Wifi router/AP and I regulary use my Laptop booted into Windows XP or Kubuntu 7.04 to watch both live TV and recorded TV at standard PAL quality over a 54g wifi connection. This works fin with only the very occasional dropout. However as ever with Wifi your mileage, interms of dropouts etc, may vary dependent on your location.
