Running the 615 in bridge mode definitely improve the stability of the unit. However, one of the lights on the unit turn orange (instead of the normal green), I suspect eventhough it works, the unit is not optimized for it's job (as a dumb switch). Don't know any of you guys have this 'symptom'? Also lately, I have been using utorrent, the upload speed for outstrip the download speed (e.g. 6kb/s download, 541kb/s upload), is the TM fair usage policy starting to rear its ugly head?
