Upload & Sell: Off
Just wanted to add a few IT things.
Try these tools:
Are you sure you are connecting at 100mbps ? Sometimes, if the setup is configured to 'auto negotiate' the speed and duplex, it will fall to 10mbps. Turn off 'auto negotiation' and set it to 100 on the NIC card and router. Also, full duplex. Really needs to be that way on all the network hardware.
Do you actually have a 'router' or hub ?
I agree, you should check on something other than Linksys. I've heard good things about the Apple network hardware.
I would check online for a firmware and driver updates for the NIC and router. Then, apply them.
This is interesting about youtube. It appears they use a 'throttling' engine. Basically, and it will be a different config for Mac,PC(depending on what OS), router, firewall, etc...In your router setup or PC firewall you want to block this address: 220.127.116.11. The subnet mask is: 255.255.0.0 Once 18.104.22.168/16 is blocked, youtube's player logic will fall back to Google's datacenters and stream at beautiful speeds. This is extremely useful for HD yt videos.
