said by rocca:Unfortunately many less expensive or older routers aren't capable of handling the full speeds (ie their CPU maxes out). I recently picked up an Asus RT-N66U and it's excellent, others have reported good results with the less expensive RT-N16.
My trusty Linksys WRT54GL is just fine at 20/1.5 and also was at 30/2 prior to that, when I was on retail Cogeco service.
I was shopping for a newer router and discovered that I did not NEED one.
That was with the latest factory firmware, though I switched to Tomato later for its QoS features.
I currently have the QoS disabled, but just updated to latest Shibby build #105 (Jan 23, 2013), and will be trying QoS again soon.
