Use of YAMon to monitor bandwidth - how to add a *wrt device into my network

Hi all,

My current setup is a Surfboard SB6141 connected to a Netgear Nighthawk as my primary router. One of the Nighthawk's LAN ports connects to a TP-Link 24-port gigabit switch which then provides the connection to most of my ethernet devices. One other ethernet device is connected directly to my Nighthawk router. The Nighthawk is the only WIFI access point (no extenders).

Thanks to Comcast's 1TB data cap, I want to better understand which individual devices in my network are hogging my bandwidth (I used 1.5TB last month alone).

Lots of reading to understand various ways and it seems like the best way is to have a router device which is seeing all the incoming/outgoing traffic and measuring bandwidth accordingly.

YAMon seems to be a popular choice, installed on a *WRT-flashed router. Unfortunately, I can't flash firmware on my Nighthawk.

*BUT* I still really want to keep my Nighthawk as the primary WIFI device.

It appears main option would be to take my "old" ASUS RT-AC66U router and flash WRT onto it. But this is where I'm a little grey for setup and ensuring the WRT device with YAMon is getting all the inbound/outbound traffic.

Would I set up such that Surfboard -> ASUS WRT as router/gateway with wifi off -> Nighthawk as WIFI access point? And if so, what would I need to do special for IP addressing? ASUS WRT would inherit IP address from Surfboard, then ASUS WRT LAN would be one IP subnet that the Nighthawk's WAN is connected to (let's say 192.168.1.x), then the Nighthawk's LAN would be on the same subnet, correct? And if that's the case the ASUS WRT device would then be able to see all the individual devices and see their bandwidth utilization using YAMon, right?

Your plan is correct.
To restate what I think you did. The surfboard would provide the WAN address to the ASUS. The Asus would act as the router for the network provide all the lan ip. The nighthawk is purely a AP and would only have a IP assigned for management

I suspect part of your confusion on the nighthawk is when you set it to AP mode all the ports become lan ports...or at least they all logically work that way.

Thanks! Looks like I'll have some fun tonight flashing the ASUS router. :)

I just wanted to follow-up on this thread in case anyone else stumbles upon it. I have Comcast Xfinity Internet Blast which is 75mbps. Prior to making a lot of changes to my network, I was continuously getting 90mbps download speed.

Long story short - I had gotten rid of my Comcast cable modem and bought the Surfboard SB6141 going straight into my Netgear Nighthawk router. I had been noticing that speedtest.net was only coming back 30mbps to 55mbps. I thought I messed up getting the SB6141 instead of one of the faster models, but with only having 75mbps download speed I thought it would be sufficient.

Last night I flashed DD-WRT onto my ASUS RT-AC66U router and hooked it into my network between the SB6141 and the Nighthawk. I then logged into my Nighthawk and put it into AP Mode. I then went to speedtest.net to compare speeds because I was really worried about network degredation introducing another device into the mix. Surprisingly enough my download speeds are back to 80-90mbps!

That said -- last night I was noticing sporadic DNS failures and it seemed like it would take a second or two before pages would start to load. Thinking DNS or something else isn't set right. I have DNS set to my main gateway - the ASUS router - and my Nighthawk is the primary access point for all of my network devices - wired and wireless. I'm running DHCP on Windows Server 2016 - Should I have the gateway set to the ASUS or the Nighthawk? Same with DNS. I have both pointing to the ASUS since the Nighthawk is only configured as an Access Point.
 
I would set the DNS as the actual dns server, many times google 8.8.8.8 is the most stable. Your router can cache things but I have more problems with it messing up that speeding stuff up. The gateway needs to be the asus device. It may or may not work to send it to another device that is not actually the exit point to the network...ie the gateway.

Thanks for the guidance -- that gateway question was embarassingly newbish haha. Makes total sense now that I read your response.

Thanks to YAMon I was able to tweak some configuration settings on my Blue Iris which changed my server's daily bandwidth utilization from 150gb to 25gb a day.
