Padavan's Custom Firmware

Chris Hand · Jul 19, 2016

Sorry to post abit off- thread - users here obviously like Padavan - I recently bought an N56U by mistake - thought it was tomato compatible AC56U - my error - I'm happy to try Padavan - it looks very good but I need the load balancing dual-wan feature & I can't find out if that is included in Padavans firmware... does anyone know please or know where I can check a full feature list?

I am using windows 10, and when it gets updated in august, it will have ubuntu bash shell which is alredy part of the technical preview. Can we compile new FW with this bash shell in win10? Did someone tried it?

Hi, thanks for keeping Padavan alive for so long! Glad to see it still kicking.

I have a 56U and after doing some diagnosis, found that the latest base firmware on my router (or some internal setting) was causing my internet to be about 4x slower than my link speed (My cable modem is capable of 100Mbps down, I was getting about 15-20Mbps consistently across multiple speed test sites). The latest Padavan firmware fixed this, I'm now getting 80-90Mbps down (Same physical cables and everything else). However, I have a new problem with Padavan now..

Wifi (2.8ghz) works great for the most part but intermittently and occasionally, it slows down to an unbearable speed then later picks up pace again. The link never gets saturated though (Wired was downloading stuff at about 500KB/s, wireless was just doing low bandwidth web browsing). I was looking for a QoS solution to prioritize Wifi traffic over wired, ran across some earlier posts in this thread linking to a QoS script ("simple_shaper.sh") hosted on a site that no longer exists. So firstly, does anyone have a QoS solution for Padavan firmware?

The second issue is that because this might not even be a QoS issue, any idea how I can try to track down what might be the cause? I was thinking resource consumption on the router, but cpu/memory consumption seems fine when I run top/ps. Utilization graphs in the web interface also look fine. This only intermittently happens

For QoS, I saw this option in the firmware: CONFIG_FIRMWARE_INCLUDE_QOS=y . I'll try building with it.

Has anyone used the cron scheduler to regularly restart the router? I have turned on the cron scheduler in the admin page and entered a cron job to test it. I can edit the cron job also by logging in to the router and using crontab -e

My test line is
5 * * * * reboot

This should reboot the router every 5 minutes (only for testing that this works)

In practice nothing happens.
If I log into the router and enter the command "reboot" the router restarts.

What am I missing?

Duh. That reboots every hour at 5 minutes past the hour and it works. Now I've set it for 3am each day and its working well.

For anyone contemplating the migration from latest stock Asus to latest Padavan (3.4.3-099) it was very smooth and easy. It was as easy as upgrading from a factory-> factory firmware except you need to manually re-load any settings.

I had a few concerns based on what I'd read but no issues:
IPV6 worked too without a hitch and I'm on Comcast. I configured for: Native DHCPv6 / Stateful: DHCPv6 IA-NA .
Blocking specific hosts from accessing the internet was possible and Padavan's wiki provides instruction on how to do so.
I was quite happy to be able to use SSH (and very secure SSH too), and HTTPS on my older RT-N56U. Also not losing traffic history when updating configurations was a pleasant experience too.
I gained the option to create a guest-wireless network, and an actually secure VPN Server (not PPTP) and VPN Client to boot!

Thanks for the info.

There was some issue reported last spring. Still can't decide is IPv6 working on Comcast or not.

using latest padavan on RT-N56 vB.
I had my virtual machines at data center, so every vm had static public ip. One used as web, dns and time server and another as mail server.
I moved it to my home (static public ip), but only one ip. I liked most to use my dns caching server (dnssec support :O ) but:
I have on my lan mail-in-a-box which has dns server for itself. And there is problem, because on router I configured port forwarding port 53 to mailserver host and cant use my dns caching server.
Is it possible to configure router to not use port 53, but 54 instead? I can set server to listen on another port or port forward 54-> 53 .?
Help me

Hot edit / idea:
or configure mail-in-a-box to listen on port 54?

Thanks for making this padavan firmware. It's great!

I need some help on troubleshooting an issue I stumbled into yesterday.

I've set up an RPi web server with a free ddns service. It works well with my N56U.

Yesterday I setup DNSCrypt-proxy which caused a failure of inadyn. I can send the verbose log later today, but what I get is a SSL failure.

Do I need to add the proxy parameter to inadyn process? Do I need to alter dnsmasq.conf or resolv.conf to exclude my web server from DNSCrypt? I have no clue, all help is appreciated.

Just information and warning!!!
Don't try to compile the firmware with Windows 10 BASH!!!
First i updated the bash shell, then I did everything, word-for-word, command-for-command as instrusted on official page of padavan wiki. After compiling the fw I flashed it and got almost-bricked device. Nothing worked! Just 1 blue light and that's about it!
I have managed, after quite some time, to reflash with official ASUS fw then with Padavan's!
DO NOT TRY TO DO IT!!!

I didn't realise that N56U_B1 has a hidden AC mode. Is this correct? I'm currently using AC51U.

Also, thanks for a great firmware. I've been using various routers for over 15 years and this is the most stable, fully featured firmware I've ever had the pleasure of using! Bravo.

The n56u in an N only router.

https://wikidevi.com/wiki/ASUS_RT-N56U is an N router

but
https://wikidevi.com/wiki/ASUS_RT-N56U_B1 is N+AC
because it has an extra wireless chip that can be unlocked with Padavan.

Not sure why Asus did this and never marketed it as a new model?

My take on this is because of the very poor (in comparison to newer models) 5GHz performance of that series model.

The chip was obviously used because it was cheaper to source than the original lower end model. But Asus doesn't want to update (or can't, while still turning a profit) the RF components to give a usable 5GHz signal that matches (even somewhat) other current AC class routers. And given that AC is 5GHz, they stopped there.

I haven't seen any reports of the B1 model running an AC network. Would you have a link handy?

Pierino · Sep 29, 2016

Didn't know that. Sorry.

The MediaTek SoC used in this model is only single physical core (but with two logical cores). Pavadan mentioned (from the URLs you linked), but not specific to AC performance, the CPU utilisation is quite high with high speed traffic over WiFi.

Hence, I would think this is one reason Asus in its goodwill decided not to turn on the AC feature but I doubted that. More likely because Asus don't want to cannibalise the sales of their higher profit margin models.

Btw, thanks for breaking the news for me. RT-N56 B1 and Pavadan firmware both look very interesting and keep the 3rd party FW fun.

Believe it or not the MediaTek SoC in B1 is more advanced that you can find in RT-AC56U/68U/88U. lol

Hi,

I had plans on updating my old RT-N56U(Firmware Version: 3.0.0.4.374) to Padavan's firmware but i saw there is alot of options to install which of these is the closest to the stock one? with all the normal features, portforward, wlan etc.
Also if i save my settings in the current stock firmware, can i import then straight to Padavan's?

Thanks in advance

Try the 'full' versions (in filename).

You will need to do a full reset to factory defaults once you switch firmware. Importing your previous settings is not an option.

Hey.
Thanks for the respond.
It seems like the Full is marked as B1 version, does it also work for my non B1 version?
