I just got a Asus RT-N56U Dual Band Router and am trying to connect it to a Times Warner Cable Modem. It seems to work with a USB WiFi Adapter but when I try to connect using cables it seems to get a signal to the Router but no output to the NIC in Computer. If I bypass the Router and connect directly from the TW Modem to the NIC it works fine. I think I'm missing something.
Went back to Fry's today and got a replacement. Installed the new one and same problem.
So, I had an extra NIC and had a vacant slot open so I disabled the onboard Lan, installed the PCI NIC and it worked. Keeping my fingers crossed.
I did try to update the drivers. I have an Asus Motherboard and Asus Router.
It worked okay when directly connected to my Times Warner Modem. Weird computer electron stuff. At least it seems to be working fine now with the Trendnet NIC.
