When the first gen Roku is in use upstairs it hawgs all the bandwidth or packets or whatever. It can slow the rest of the devices to a crawl, and especially puts the whammy on game pings. I've read this is due to the Roku's aggressive buffering-- neither the laptop nor the big HTPC hawg bw when streaming vid. I've tried the deal where you hit Home 5x, rewind and forward 3x and get the advanced options, where one can ostensibly set down the bandwidth, but this has only helped some. If there's an alternative for < $100, I'd be interested. I've tried futzing with the QoS on my Netgear router, but it hasn't helped either AFAIK.
I've done some router QoS stuff. Set the MAC addy for the Roku to low and that of my gaming rig to highest. [crosses fingers][does not hold breath]
I was going to say try some router options. I have DDWRT on my router and I know there's options like that.
Modern routers use DDWRT? I thought that was 80211g Linksys WRT54G-timey stuff. [Edit] Well I'll be damned . . .
DDWRT is even better than before. You have to look in the forums though for the latest releases via FTP.
/me knocks wood . . . This seems to be working so far and I haven't had to dink with DDWRT yet. I did download some bins just in case since it's so old.
