Re: Devolo Homeplugs as a network option?
 

So perhaps the best for me would be to get the gaming pc wired directly by ethernet into the BT/Bethere connection, and use homeplugs or separate longer cat 5 wire to connect the other one......?
Basically ping will matter on one computer, less so on the other.

Yes... Wired is always going to give the lowest possible latency.

If you worried about ping that much ask BE to turn the interleaving off but your Sync speed will probably take a hit unless you have a very good line.

I've never used them, but I'd think it is the same as using wired ethernet. It's faster than wireless, more stable and more secure. I can (occasionally) see the wireless networks of three neighbours, and I've had to experiment quite a bit to figure out the best place to site my router to get decent wireless coverage (I'm on ADSL, so can use any phone socket for the router). Even then, I find I often connect at 24Mbps rather than 54. Not a big problem, but higher speeds are nice when transferring large files. So, short answer: If your wireless coverage is patchy (and tbh, it often is with neighbours' networks, wet dogs, DECT phones and Microwaves), they sound brilliant. All the advantages of wired but without the wires. They seem a bit too pricey atm, but I'd consider them if prices drop.

They do sometimes get affected by sources of mains electrical noise but i've never personally experianced it.

Only problem I had was with UPA and Home plug adaptors on the same ring main.

Obviously they do add some Latency since they have to modulate the data onto a carrier signal that can be used over the Mains without causing problems for electrical kit
