Hoping to use LAN/WAN Bandwidth Monitor

[John Doran]

Dear all,

I was hoping to use LAN/WAN Bandwidth Monitor as described here:

http://www.asus.com/support/FAQ/1008717/

I installed Asuswrt-Merlin v378.53.0 on my Asus RT-AC66-U router, but did not find this feature. The article linked above does not specify which router types actually support it. Does anyone know how I can access it?

A bit more background for those that have the time: I am hitting the fair use cap of my "unlimited" subscription because since three weeks ago I am all of a sudden uploading 50 GB per day every day. I am trying to find out what application is triggering this volume. I have *a lot* of devices in the house eg 2 Synology NAS, 4 PCs, 3 Ipads, 3 smart phones, 4 smart TVs, 4 routers (the AC66 as external connection, 3 configured as WAPs with wired connection),... They are all using dropbox etc. but no offsite backup services. Most are on fixed IP. I think I just need a central monitor like the one linked above to pinpoint the problem to a device. Then I can install specific application bandwidth monitoring on that device?

Pointers welcome,

-John

You need an RT-AC68U or higher model to use that feature.

Have you enabled LAN Sync in the Dropbox Preferences for all devices? How are you determining that you are uploading 50GB per day / every day? Your ISP has issued a warning? Or, is that what the router is showing (erroneously, I'm sure)?

I had a similar problem a while ago, and used the Per Device function of the Traffic Monitor to track down the offending device (an Apple TV in an infinite firmware upgrade loop). This was on an RT-AC66U.

You can find this functionality under General -> Traffic Manager, in case you haven't seen it before.

Thank you L&LD for a quick response. As luck would have it I had a RT-AC-68U lying around. Once I had downloaded the latest official firmware it was easy to find the Adaptive QoS and Bandwidth Monitor. So thanks for that! (I did not try the latest Merlin version for the RT-AC-68U). And yes, the measurements come from my provider: historically download was 10-15GB per day, and so was upload (I can't even explain why upload would have been so high); upload then recently jumped to 50GB per day; my provider notified and squeezed me when combined monthly volume hit 1000 GB...

Thank you Netnoob for your response as well. Where did you find the "per device function of the Traffic Monitor"? Is that on the official firmware or somewhere on Merlin? (I had the recent Merlin version on the -66 earlier today and it allowed me to save tomato rstat and sstat files, but those seem impossible to read if you don't know scripting)

Are we sure that the latest RT-AC-68U firmware is working well? I noticed two problems:

(1) The Bandwidth Monitor feature showed 15-20 Mbps UP-loading, while in reality I was downloading a large torrent, shown in bittorrent on my NAS as 2-2.2 MB/s (times 8 that seems in line with 15-20 Mbps). Traffic Manager on the router correctly showed 2500-3000KB/s (I assume a bit more than the bittorrent rate due to protocol overhead). Did Asus just get UP and DOWN wrong in Bandwidth Monitor??

(2) Eventually the AC-68U seemed to stop working though, and no amount of resetting or verification of settings helped. I could ping out to google from the router itself (using Network Tools). I could ping the router itself from within the LAN (from cmd). But I could not ping google from within the LAN. I took the AC-68U down for now.

You need to enable 'Per device traffic monitoring'

Works great on my RT-N66 - I am running John's Merlin fork but I should imagine it also works fine on recent Merlin builds.

I can see real-time, daily and monthly down and upload data for all my devices.

Like netnoob it also worked great for me when I had a misbehaving device (an iPhone stuck in a restore loop that downloaded several hundred mbs of data)
