Asuswrt-Merlin 376.49 is out

[RMerlin]

First of all, thanks Merlin for all the hard work and the excellent firmware result of it.

Just upgraded from 48_3, did a Factory Reset and when configuring everything again I noticed that "Advertise DNS to clients" option is missing from OpenVPN Server settings.
Is this a bug (i think so) or was removed for some reason?

I was able to enable it manually in case anyone has the same problem by executing the following command:

nvram set vpn_server1_pdns="1"

Thanks, fixed. It's an issue in Asus's code that I had fixed a few months ago, but came back as I switched to their webui code in 3677.

These past few weeks I've had 2-3 reports of issues with MAC filter names, yet I've been unable to reproduce any of it so far. Can you describe in details the steps you are taking, and the actual results?

Hi Merlin,

All it is is the name disappears and just shows the mac address twice.

Perhaps if I were to factory reset and re enter the whole lot that may cure it, but it doesn't bother me if I dont look at it !
I'm sorry there is not much detail to add.

When I add a new name to filter either the whole list disappears and just shows mac ads where name should be. or some work and some dont.

Thanks

Either you really haven't updated as you think or you need to clear your cache.


No problems here with my RT-N66U - updated, pulled the power plug and waited 5 minutes. Started the router and after 10 minutes did a gui Reboot.

Solid ever since.

So weird but it works now after i updated again. Weird that it didnt work the first time when i just repeated what i did then now.

Network Place (Samba) Support option is enabled under VPN Server - PPTP and i can't see my devices while using VPN service

anyone facing the same issue ?

Had DHCP issues with 376.49_2 on my AC87R

Just got home today from my pre-Christmas vacation and saw there was a new update.. I decided to take the chance even though Merlin moved the version to beta due to a boot loop. After the update everything looked ok until my DHCP hosts started to renew. The system log kept stating:

no leases left​

Well I took the plunge and deleted all the static leases and tested and the DHCP clients were correctly getting addresses from the pool. Then I stared to re-add the statistic leases and everything seems to reverted back to normal.

Very strange but just wanted to see if anyone else had DHCP issues when they did the update? So far everything seems to working fine after the DHCP issue. I will be testing out QOS later next week after this smokes in.

Just an update:

I am seeming memory utilization at 61% now vs on the previous version of Merlin on the router only hovered about 35%. I can't seem to find what is using the additional memory but this could cause some issues with folks that use other applications such as BitTorrent and media sharing from the router.

Media Bridge

Hi, I have been using 376.48 for a while now in media bridge mode. I bridge the 5ghz band to my primary router and then it would rebroadcast on the 2.4ghz band to other wireless clients. Although asus says it is not supposed to work this way (both radios active) it worked perfectly. After upgrading to 376.49 this stops working. Is that by design as a fix or is there someway around that? I even try enabling the 2.4 radio using telnet (wl -i eth1 up) but it won't stay on, and the wl -i eth1 status message show a BSSID of all zeros.

Ideas?
Thanks
Dave

Check /etc/dnsmasq.conf to see how many leases are available total. Also make sure the message you are seeing isn't caused by a bug in Windows 8 where it requests a DHCPv6 lease even tho it's obtaining an IP through stateless configuration (RA).

Check with "top" what's consuming your memory. Also check the content of the ram disk (/tmp).

Solved a problem by changing the Encryption cipher setting in Advanced settings.
For some reason the openvpn server now in 376.49 doesn't start if the Encryption cipher is set to None!

Might be a limitation of the auto-cert generation code (which is from Asus).

Personally I never understood why the original OpenVPN code even allowed setting encryption to "None" (or to the even more confusing "Default" value). I'm often tempted to remove these two settings.

Same with "Compression" settings - there are "Disable" and "None". Any difference between them?

I installed RT-N66U_3.0.0.4_376.49_2

and yet it tells me that ive got 3.0.0.4.376.45_0 installed?

Hi,

This simply means that the installation/upgarde failed!

Typically this has one three reasons:

1. Either there was not enough memory for doing the upgrade (remove the USB devices and reboot before you upgrade),
2. or it was the beginners errror 1: you did not unzipp the downloaded firmware (should be a .trx file),
3. or beginners error 2: wrong file downloaded (check carefully the router name).

With kind regards
Joe

NAT Acceleration

It seems that in 376.49 setting NAT Acceleration to Auto on my AC68U will show "CTF only" yet in 376.48 I could select "Level 2 CTF+FA" and it seemed to be enabled and working.

Was this a bug in the previous version, by showing CTF+FA but was only actually CTF? Or is there a problem in this version not allowing FA on AC68U?

 

[KGB7]

The 2.4ghz band is broken for me. Laptop only connects at 54Mbps and Galaxy S4 connects at 13Mbps. I changed every setting and i cant get it past 54Mbps for laptop and 13Mbps on S4.

Turbo QAM no longer works either, unless you set Wireless Mode to "AUTO". But if you set it to "AUTO", then Galaxy S4 connects at 6Mbps regardless if Turbo QAM is ON or OFF.


At 40mhz, the connected speed is half of 20mhz for both devices.


Done speed test and full reset. All settings entered manually.


5Ghz band works fine.

ive been getting this in the log after the update. Anything to be worried about?

 

[Erroneus]

Anyone else having problems with the 2,4GHz radio dying on RT-N66U? Suddenly my 2,4GHz SSID disappears and I have to disable the radio and enable it again for it to appear.

 

[redpants]

For me its the opposite. 2.4ghz never goes down but 5ghz drops once in a while...

 

[TNR27]

Updated to this firmware today on my RT-AC87U. At the top of the GUI, where the SSID names are listed, my 2.4G SSID name is listed properly, and the 5G SSID is listed as 'undefined'. Everything seems to be working properly, and the 5G network can be seen with the correct name. Seems to just be a graphical bug.

same hear except 2.4 is labeled as "undefined"

Check /etc/dnsmasq.conf to see how many leases are available total. Also make sure the message you are seeing isn't caused by a bug in Windows 8 where it requests a DHCPv6 lease even tho it's obtaining an IP through stateless configuration (RA).

Not using IPv6 since AT&T Uverse is unreliable with their current implementation. I use 100% static addresses assignment I leave a pool of 20 open just to bring on new devices. Oh well re-adding the statics took a while but fixed the issue.

You must be running something that takes up memory, because mine has a lot more available:

Nothing else running I do have startup scripts that add a couple of hostnames to the DNSmasq for lookup purposes. Here is my top you can see nothing is using up a lot of memory httpd is the biggest consumer of 1.1% of physical.

It seems that in 376.49 setting NAT Acceleration to Auto on my AC68U will show "CTF only" yet in 376.48 I could select "Level 2 CTF+FA" and it seemed to be enabled and working.

it wasn't. The BCM4708A used by the RT-AC68U does not support FA.

ive been getting this in the log after the update. Anything to be worried about?

It's DFS doing what it's meant to do: ensure that the 5 GHz channel you are using does not conflict with nearby radars that use the same band. Looks like Asus left logging enabled for it - or at least it's the first time someone posts DFS log entries.
