Well, as mentioned in another review, the firmware in the initial shipment of these (3.0.0.3.72) is broken. Not buggy, not unstable, but broken. You CANNOT connect to the Internet with the factory firmware, at least in the initial release. I purchased one, returned it in exchange for another one, and the second one had the exact same problem. As discussed on this here: [...]You must manually enter a URL [...] then change to a language other than English, then update the firmware. (The current version from the ASUS website is 3.0.0.3.90 as of 1/13/2012) Of course, that means you need to download the firmware first, since you can't connect to the Internet with the factory firmware. And of course, a router is required for most people to access the Internet, so... well, you can see where I'm going with this.After the firmware update, things were much better. I had the Internet connection set up in a few minutes, and the speed was unbelievable. Certainly the fastest consumer wireless on the market right now. It has nice features, like 6 different SSIDs for guest networks (3 for each band.) You can choose whether or not to give those networks access to your primary network, and since you can set up multiple SSIDs, you can have different settings for each. It also has parental controls, good QoS, a VPN server and some other nice features. It supports Zoneedit for dynamic DNS, so I was pretty happy about that. (Neither the Cisco or the Linksys models I have tried do.)One feature that's present in the Linksys E4200, but not on this router, is an SSL web GUI. I work in IT, and it bothers me administering my firewall over plaintext HTTP. Probably not that big a deal to home users, but I don't think it's that difficult to implement an HTTPS server for the admin GUI. It also makes this unit completely unsuited for deployment in a business environment, where security is paramount. I'm hopeful that it'll be in a future firmware update. I could probably use this router for a lot of small-business clients.As far as wireless range goes, this blows away both the Cisco E4200v1 and the Netgear WNDR3800, both of which I tested in the same placement as this one. I get full signal in all corners of my house, which isn't too big, but both the Netgear and Cisco routers got medium signal in the corners of my house. I have 5 wireless devices and 6 wired devices, and speed thus far has not been a problem. I stream video without drops and file transfers are quick. No complaints.I really wish ASUS hadn't made the error of shipping this with broken firmware. They will undoubtedly have a return rate nearing 100% until they get the new firmware on shipping units. Had it not been for this, I would easily give this product 5 stars. If it had HTTPS on the GUI, I'd say it's a perfect device.UPDATE 10/12/2012So they fixed the firmware issue within a couple weeks of release. Now, they've released a firmware upgrade that adds HTTPS functionality. I'm upgrading my review to five stars!UPDATE 11/16/2012I changed the title of the review, because, other than price, there is no longer any reason not to buy this product. It is the best wireless access point on the market, save for the new ASUS RT-AC66U, which is just an updated version of this product. (New radio, supports a new standard that nobody uses yet.) I don't use it as a router, so I can't qualify those features, but as far as range, features and consistent connectivity, you can't beat this product at any price.
