Asuswrt-Merlin 378.53 is now available

[RMerlin]

OOM-KILLER makes it sure i can't do anything on my router anymore. Only 1 GB of free swap left (file, not a partition) and it kills whatever process is using memory... Can't run rsync anymore, or anything that uses a lot of ram. Renders the router pretty useless.

It's a router, not a computer. You will need to stop running whatever you are running on it that requires so much memory.

on my tr-ac66u I seen some wireless clients which are registered as wired and I see a wired client which says it had static ip (pretty sure I just set up dhcp)

Running 378.53 on RT-AC68U configured as a media bridge. In system log->wireless log->Rx/Tx rate is always shown as 6 Mbps. What does this mean? And also, SNR shows up always as 0 dB although signal is at -29 dBm and noise level is at -92 dBm. Are these just a interface bug?
[RT-AC68U is able to connect to my main router (WRT1900AC). I have measured speeds at above 400 Mbps between the two.]

SnR=always 0
Noise= -92 normal( with 68u its always around -90) dependind of your environnement
Signal=-29 ( very good signal,the best you can have is -25)
And for your 6Mbps, do some transfer to your Wireless device and it will change
So i see no problems with those logs

Sorry for my English

I've setup Parental Control for my kid's tablet, enabling Adult and Streaming and Entertainment categories. As a result Google.com got blocked off completely. This seems to be too harsh, especially for an Android device.
Is this handled by original Asus code or can be adjusted in RMerlin releases?

Thanks! Rx/Tx rate seems to stick to 6 Mbps/6Mbps even when a transfer is happening at 20 MBps (160 Mbps). Tried refreshing, that didn't help.
Expected SNR(dB) = -29 -(-92) = 63 dB. Not a big thing to complain, but just found it odd.
Also 2.4 GHz light stays on in a media bridge mode using 5 GHz. The interface clearly says 2.4 GHz is disabled. I didn't see any rogue network from my clients. May be just a rogue LED

After I´ve updated to 378.53 (on AC68U) and enabled just Ipv6 (6to4), the test on http://test-ipv6.com/ (or other ipv6 test sites) is negative.

Can someone help me?

This uses Trend Micro's Web Reputation System database, beyond my control.

Google shouldn't be blocked however, make sure you didn't also enable another category that might cause this.

So, I got some info that may help to clarify what is the problem and I also noticed that when running the route command over ssh, in STRICT mode and EXCLUSIVE dns mode, the command takes up to 15 seconds to answer the routing table... when in RELAXED or DISABLED, it is instantenous.

My VPN provider informs something about forcing a update in resolv.conf when running openvpn from linux, does this have anything to do with Merlin ?

https://forum.vpn.ac/discussion/13/running-openvpn-in-linux-terminal-with-no-dns-leaks

Well, thanks again for any help!

I finally managed to track it down. It's not a bug in the firmware, it's the ovpn config you are importing that's telling the router NOT to run the proper cleanup script at exit time.

Remove the following line from your custom config field:

explicit-exit-notify 1

Should be fine after that.

 

[RMerlin]

I am using the policy rules (great feature) is there a way to automatically reconnect when VPN is back on, in case the "Block routed clients if tunnel goes down" kicked in?

It already will once the tunnel comes back.

Thank you RMerlin for the great firmware!

I have a seemingly strange issue: After upgrading my RT-AC66U FW from 378.52_2 to 378.53_0, the 'DHCP' screen displays incorrectly (without any side or top navigation) and it does not function. I have a lot of settings, so I was hoping not to have to clear NVRAM, etc unless that would certainly fix my issue.

EDIT: I just realized that the PPTP Server (Advanced_VPN_PPTP.asp) and VPN Server pages (Advanced_VPN_OpenVPN.asp) have the same issue.



Can you help?

Thank you in advance!

Do you have any manually assigned IPs and device names? Make sure your device names don't contain any special characters (no $ " ' .).

 

[thegorilla]

Do you have any manually assigned IPs and device names? Make sure your device names don't contain any special characters (no $ " ' .).

I do have manually assigned IPs and names, but as far as I can remember, names have only alphanumeric, underscore and spaces. Because the page is messed up, I can't see the assignements.

I also found two other pages that have the same issue, one of which (PPTP Server) I have never used.

 

[john9527]

Because the page is messed up, I can't see the assignements.

Can you check them in the Network Map on the default page? For safety, I'd also not use spaces in seeing if it can clear the problem.

Open your web browser's console, and look for any Javascript error. Post the line containing the error.

Folks I think that something is missing in this version, I am trying to setup WDS and the settings to use WEP when choosing OpenSystem as the authentication method is missing.
Here are the settings in the Asus firmware versus Merlin.

I've verified that there are no spaces, only alphanumeric and dash. That is for connected device, I can't confirm for unconnected devices, since I can't see the assignments.

Here are the errors using IE11 Developer Tools. I'm sorry I can't figure out how to copy/paste the text from the console window, but the errors are: "SCRIPT1004: Expected ';'" and "SCRIPT5009: 'initial' is undefined"
