Just got one and now Wifi seems VERY sluggish. Have a Motorola 5120 modem. Do I need a faster modem to keep up? Any other suggestions?
Does your modem have wifi also ? If it does disable it, btw disconnect the power cord on the TC and re-connect and see if things are faster.
I had that problem when i got my first TV, i had a modem and a wifi router and i had to play a little bit to get work good but in the end i removed the linksys router.
Rarely i get that issue now but i know i just unplug and plug back and speed go back to normal; might aswell check if you have intruders in your network.
Hope it helps.
What's sluggish? The 'net? Local?
I just bought one Saturday (open box) and it worked like a champ.
Open up Terninal and do ping tests to another computer, your TC, your modem (if you can) and say.. google.com or something.
