I recently bought a Linksys E3000 and flashed it with DD-WRT (4/11/11 mega). At the same time, I bought a TiVo Wireless-N adaptor (v1.1.E1). I've set up the router with WPA2 Personal on the 5MHz and 2.6MHz bands. The TiVo adaptor won't connect to either band. I am certain about the network SSID and password, and I've tried simpler passwords and other levels of security. The only way I have made it connect so far is to leave the 5MHz band unsecured. I would rather not do that. I spoke to TiVo technical support, we went through lots of troubleshooting steps (including some of what you see above), and the support rep decided that the adaptor probably requires a replacement. Before I go through the return process with Amazon, can anyone think of something else I might try?
