Thanks for the reminder. I just installed it on Sunday. Or Saturday. Anyways. Completely painless install. The router was smaller than most I have encountered. No external antenna. I configured the whole thing wirelessly with my iPad. Had to reset/reconnect 3 different times due to changing password, setting up wireless security, and something else... the SSID, I think. Each time was flawless. It's a 150MBps router (the connection on her computer indicated a speed of about 130MBps) which is more than enough for what they need. We also connected her new Roku to it and it was streaming HD flawlessly. Like I said, I also got the little thumb drive wireless device for her computer and that setup was pretty simple too. I was surprised the setup didn't come on the flash drive itself, but whatever. I was extremely happy with the whole experience and would definitely recommend it to others. Much cheaper than other setups and seems to have all the security and options I was looking for to protect them.
By the way, I've never played with a Roku before. Very cool little interface if you don't have another way to consume those services. I did end up setting up a shit-ton of accounts for my mother-in-law that day. It got old after the first few.
