I've Asus RT-N66U and TP-Link MR3420 v1, 3G connection speed I got from supercharge E372 is equal. Can't see any different too, on the speed both routers connect to 3G after cold bootup/reset.

Didn't try it on E398 though (upgraded couple weeks back) since I've left MR3420 at hometown.

When u really want it times, u'll find excuses & ways to get it.

TP-Link MR3420 can't support full HD streaming from my NAS to Apple TV smoothly, just happen that time a friend has the same setup & use Asus router, he doesn't has such issue, so I just duplicate his setup.

Yea, Blacktubi already answer, I've tried E398 on Asus & it works. 1 minor glitch I noticed is ~50% of the time when I cold boot the router, E398 can't connect to internet, toggle router internet on/off switch will clear the issue, still trying to understand what is causing it, didn't have such issue on E372 (the issue did occur but very seldom).

I try on both factory and Merlin firmware, both work same. Didn't try other custom firmware. Main reason I try Merlin is dual-wan support, but for my usage, I didn't notice any different.

I'm waiting Apple TV 3 JB too!

Main benefit of Apple TV to me is AirPlay, this's make playing video/audio/photos really convenient, being from internet/NAS/Apple devices/PC.
*AirPlay from PC can be done using AirParrot.

My previous router (TP-Link MR3420) can't support smooth full HD AirPlay from NAS to iPad to Apple TV, Asus pass the test easily, I even try 2 full HD video concurrent from NAS, it still works! *That time I didn't know MR3420 has wifi-N issue on factory firmware, should have ask all the sifu around here first.

Should be I Don't Know.

E372 is in the list. E398 is not supported when I contact Asus few weeks ago, I took the risk to get E398 to try it, & it works! (Blacktubi agree to take back if not support, that helps greatly). I don't have MF680 to try, I don't mind trying if anyone willing to loan me.

I guess not many ppl buy Asus router to use with 3G/4G modems. TP-Link still most popular choice.
