I had originally planned to buy a WRT350N, but it seems like local stores here don't carry it anymore (don't ask me to buy online, it's not one of my option). I'm thinking of getting the WRT610N instead since it's available everywhere but my concerns are: 1. Will it drop connections? Any experience with this? 2. Can it work at 2.4GHz and 5GHz simultaneously? Some seem to report that it can't. 3. DD-WRT firmware is still in development. 4. Internal antennae may not be better.
