Style Name: N900 Mbps + ADSL/VDSL modem
Important update, please read below
-----------------------------------

I have owned this router for over a week and been having a hell of a time with the DSL ping and speed. I search everywhere online on how to resolve x2 higher ping (from 15ms to 30ms) without success. Firstly you must remember that any new router will face the dreaded DLM ( Dynamic Line Management - https://ttb.custhelp.com/app/answers/detail/a_id/651/~/dlm-%28dynamic-line-management%29 ) that can last week(s) finding the optimum speed. But anyway, here are the things to help.

Here's how to improve speed and decrease ping:

1. Update firmware

2. [wireless] settings
a) Disable [WPS] (security risks)
b) 2.4 GHz
i) Disable [b/g Protection]
ii) Set [Channel bandwidth] to [20 mhz]
iii) Set [Control Channel] to one of [1, 6, 11]
c) 5 GHz (Dont touch)
3. [WAN] settings
a) Disable [uPNP] (security risks)
b) Set [Connect to DNS Server automatically?] to [no] and add [8.8.8.8] and [8.8.4.4] to DNS Server 1 and 2 (Google Public DNS).
c) !important part! Set [MTU] to [1442] and [TCP MSS Option] to [1400] (Improve ping and connection speed).

4. [Advanced] settings, select [DSL Setting] tab
a) Set [DSL Modulation] to [VDSL2] (vDSL line)
b) Set [Rx AGC GAIN Adjustment (VDSL)] to [performance].

I couldn't be more than happier now, extremely fast and great WiFi range/speed! Good luck!

----------------------------------------

Update: 2014-09-16

Unfortunately I've found my vDSL connection dropping again and with the recent DLM effects my connection speed has dropped from 48Mbps to 20Mps. Looked at Asus wireless forum and it seems others are experiencing the same.

Style Name: N600 Mbps + ADSL/VDSL modem Vine Customer Review of Free Product ( What's this? )
Firstly, it should be said that this is a high end modem router and is designed for use with a dial-up telephone line based adsl internet service and not for use with a cable or external modem.

This router has a modern and up to date appearance, stylish and suitably high tech and will look well on any work desk or even in the living room.

The wizard based setup was easy and straightforward and for most users all they need to do is input their ISP user name and password to access the internet with no need to use the supplied CD. Many adsl routers such as the AVM Fritz! Box Fon 7390 Wireless 4 Port VDSL/ADSL2+ Router DECT VoIP Phone Adaper that I usually use myself now support internet access from a cable, external modem or another router. Not so this router which is limited to an adsl connection only. Although Asus claim a maximum speed of 600Mbps this is slightly disingenuous as this is in fact the combined speed of the 2.4 and 5Ghz network streams. Rival high end routers from Netgear and other now support a single band connection of 450Mbps or higher - although few network adapters yet can handle this. Perhaps I overlooked it but I could not see anyway of using this router as a repeater to another existing router network. As another review has already pointed out this device does not allow for MAC address spoofing - this is a way of fooling some ISPs that insist on their own specific routers being used by allowing the user to input a suitable MAC address into the router settings and which is then passed on to the ISP during the connection process.

Style Name: N600 Mbps + ADSL/VDSL modem
Just wanted to share what an amazing router this is in terms of setup, options and function.

Unpacking:
Came with power cable, ADSL filter, ethernet cable and CD & Manuals etc - no problems here.

Internet Connection:
So I updated the firmware when I first got it and chose internet connection autoconfigure (happens when you open chrome/ie/firefox) when connected to the router via ethernet. Did all the configuration itself and requested username and password which I entered and it worked, just like the "under 30 seconds" video on youtube.
(I am on a sky ADSL internet connection, the original router has its username and password hardcoded and you have to use Wireshark to retrieve them both)

all settings that it autodetected are the same as those on the original router (VCI,multiplex,etc etc) so glad they are not an issue. The internet connection is as fast it was before 16Mb/s (2MB/s). Not lost sync or internet use over the last week or so.

Wireless Performance:
My house is a victorian 4 floor (basement) with thick solid walls which are the worst for wireless transmission. The new Sky router (white box SR101) has poor wifi reception - it would transfer on the wifi network transfer at 3MB/s at best - with the Asus I now get 6-7MB/s.

Also, where I had no reception I now get 1-2 bars (out of 6) and primarily at long range the 2.4Ghz is better than 5Ghz (as expected). Virtually everywhere in my house in terms of internet speed via Wifi gets 16Mb/s (2MB/s) even if its just 1/2 bars out of 6 - great news!

My wireless printer picked it all up and worked, so no problems there!
