Just wanted to ask around if some rMB users here wouldn't mind checking something for me and sharing it here: I'm getting what I think is a pretty low bitrate on my wifi network at home with my rMB. Using Network Utility and looking under the info tab, I see a link speed of 54 Mbit/s. Would some of you guys mind launching Network Utility on your machines and reporting what you get, so I can see if this is (as I suspect) really poor? I'm not concerned about the rMB itself.. Am pretty sure this is because of the old ADSL box I have at home which has been around since 2009 or so. I doubt it has anything close to current wifi spec, but I'm switching over to fibre optic soon so I'll get a whole new router then and it should be much better. But for now it's a bit annoying. I was hoping to use my 2010 i7 MBP as a home server to be able to just stream whatever I want from my large collection of series and films (much like I currently do with Air Video on the iPad) but it's not working as well as I'd like. It could also be the fact that some of my video library is on an external USB drive (the MBP only has USB 2.0) so it could be struggling to get HD video out fast enough. But I doubt this is the source of the issue because it has absolutely no problem playing this kind of video content itself - so it really feels like poor wifi speed from the router is the culprit here. Also, if I'm in the same room as the ADSL box, it's pretty flawless, no dropouts. But a little further away and it stops and hangs for buffering often enough to be annoying. Anyway, what with all the very latest super duper wifi spec the rMB is supposed to have, I really doubt that it is the problem here. I'll check at the studio tomorrow where we have a much more up to date router and see if it's better there. But while waiting for the optic fibre internet to get installed I would like to get it to work a little better anyway.. I'll try changing wifi channels later when I have some time. So please go ahead and report what wifi speeds you're seeing, would be great to see that I'm not expecting anything unreasonable here!
