Asuswrt-Merlin - custom build of the Asus RT-N66U firmware

[RMerlin]

Having a problem with the latest firmware, I am locked out of the web interface, getting a connection refused from all my machines.

EDIT: seems to happen right after accessing the wireless log page, it somehow screws up the httpd on the router. not sure why, but after reboot its back to normal, I am staying away from the wireless log page for now.

Did you have any wireless client connected (2.4 or 5 GHz)?

Dynamic or static IPs on them?

yes- both frequencies

mostly dynamic IP's

I am able to reproduce the problem. going to the wireless log page seems to crash my httpd process. Anyone know the exact command syntax to restart httpd ?

cd /www
httpd

That will block that shell as httpd doesn't detach itself. While it's running go to the Administration -> System page, and click "Apply". The firmware will restart it in background.

Can you send me a PM or an Email with the following file?

/var/lib/misc/dnsmasq.leases

Also the output from this command:

cat /proc/net/arp

Thanks!

done and done

Fixed. The issue occurred if you had a network bridge, meaning a wireless associated MAC couldn't be found in the arp cache.

I'll push 3.0.0.3.162.14b on Github and my website in the next few minutes.

Thanks for testing this diyguy!

NP, thanks for the quick fix!

It will list currently connected clients. It either means the laptop isn't currently connected, or it's actually connecting to the 2.4 GHz radio. Check System Log -> Wireless Log for more details.

the laptop is definitely connected to 2.4 (i am looking the sysinfo from there ), but it is not connected to 5 (i am 3 meters from the router and it supports 5ghz, so the laptop should have no problems to connect to it), which is identical to 2.4ghz.
the question was: is the device connecting and using 5ghz on demand, only when needs more bandwidth, or should it connect immediately to it by default?

Hi!
I don't know where to ask, so i will put my question here. Forgive me, if I'm doin it in wrong place. I'm preparing for switch from asus firmware to Merlin-based. Is in it any more advanced URL filtering options? I mean to set a specific page(s) that will be blocked to a specific IP/MAC/Range or group (ex. 192.168.x.3, 192.168.x.8, ...) of computers. Thanks for any answer

Thanks for this - the sd-idle routine is working perfectly.

Any progress on the wireless schedule issue?

The laptop will connect to either 2.4 or 5 GHz. It will depend on your laptop's configuration.

If you have the same SSID for both radios, then you will have to go into Device Manager, edit the advanced proprerties of your network card. Some network card (like my Centrino 6230) have an option to tell which radio to connect first.

Otherwise, just give two different SSIDs to the radios, and configure a connection with the 5G SSID.

The filtering features are unchanged from the stock firmware. However if you are skilled with iptables, my firmware makes it easier to create and apply custom rules, through a script that gets run after the firewall is activated during boot.

The issue still exists in the beta Asus sent me last week, so I reported the issue to them.

Fixing it won't be so simple, so I'll give them a chance to fix it themselves before trying to do so myself. The problem is the current bug is caused by another fix they did related to radios, so it will be tricky to have both issues fixed.

Does anyone know where the Static DHCP entries are stored on the router? is there some sore of conf file ? does it get read with dnsmasq?

Also I have this pesky certificate error when I go to the routers web page since I am using HTTPS, is there anyway to fix that ?

No, that's understandable, thanks for looking at it and reporting it.

DHCP reservations are stored in nvram, in the dhcp_staticlist variable.

You can't get rid of the certificate warning, as the router is using a self-signed certificate (unless maybe if you want to spend 150$ on purchasing a one year certificate and adding it to your router, but somehow I doubt it ). This is a normal security feature of https. Some browsers however allow to add an exception to them, telling them not to warn again.

eh, on windows i see the pc connected on 5ghz at 150mbps nominal.
unfortunately i mostly use ubuntu, and although i can see it with "iwlist scan", i don't know how to force a connection to it.

No idea if Linux can be told to give priority to a given radio frequency, you'll have to do some Googling. It might be simpler to simply use different SSIDs (I use name and name_5G at home), and configure the connection specifically for the 5G SSID.

i googled a lot already, but could not find a solution (yet).
i'll go for separate names, thanks.
keeping the same name is useful only for fallback connection, or is there some kind of channel bonding?

I'm trying to adapt a dnsmasq script for ad blocking which I found here

http://www.dd-wrt.com/wiki/index.php/Ad_blocking

before attempting, I wanted to know if anyone here has done this already ?
