Thanks very much for the information. A friend has an Asus router (RT-AC68U) with your firmware and recommends it, but he said the issue he is running into is his router is running low on nvram. So I was advised to look for one with something higher than 64 KB. Being short on time, I am the kind of person who tends to buy up in capability with the hopes of avoiding problems down the road. I wish I had time to tinker, but I simply don't. But I need the flexibility that your firmware and the Asus routers provide.
Once again, thanks very much for the info!
