RE: Newbie needs Network / media centre solution!

[Marcus Warrington <marcus.warrington@xxxxxxxxxx>]

I wouldn't personally rely on wireless for any application that required
high bandwidth or consistent throughput. Its just too susceptible to
external influences and interference.

I use wireless (54g) for internet browsing on a couple of laptops at home,
everything else is hardwired (cat5e 10/100). When I first started using
wireless no other access points where around, but now a few years later
there are at least another 6 access points that get detected. The through
put and reliability has also deteriorated as more neighbours have gone
wireless. I seem to remember that only 3 of the 11 (or 13) channels
available are actually unhindered by the other channels. i.e. 1, 6 and 11
are the ones to use, otherwise you get interference from the other
channels.

For streaming any video (and especially HD) I would recommend you look at a
hardwired solution.

I think you'll find that should be 200 Mb/s i.e. Mega bits not Mega Bytes.
I'm sure I read a review that tested these and found its throughput was
nearer 11-12 Megabyte a seconds. That should be adequate for your Blu-Ray
(48Mb/s)

I think the only way you'll approach anywhere near 20MB/s is by hard wiring
with cat5 or 6 and using Gigabit network cards. AFAIK there's no way you'll
achieve anything like that wirelessly.
