Speaking of returning routers, I spoke to Amazon and they said they would take this router back after the regular return period (they sent a return code or whatever) because of all the complaints, but maybe that was just for me. Dunno. I actually didn't return the router, however, because I was too lazy. Just complaining more instead!
But now, I'm giving up, it's time to buy a new router. Never got this thing to work more than 50% of the time. The 50% of the time it is not working is because the 5GHz drops out.
@Mackerel: I did raise a new topic. He asked if he should return the router, and I gave him another reason if he was not already aware of it.
