CUSTOM/FORK RMERLIN FIRMWARE

[RamGuy]

Well, that explains a lot. Thank you

 

[L&LD]

Just an update on my speed issues with the final 378.50.3 hggomes firmware I'm still testing on my RT-N66U.

Please see my original posts a page or two back.

I have left the network idle for over 24 hours now and no matter what, the best performance I can achieve is about 25% less than the RMerlin 378.50 final allowed.

However, before I flash the RMerlin firmware, I tried testing both upload and download speeds. Previously, I was only comparing the Wireless to LAN throughput which is an upload spec.

Copying the same file to a different destination directory gives me a 29.1MB/s peak download speed from the router to the wireless client. That is an improvement of about 16%.


I will leave this firmware on for the next week or so until I have time to try more variables. Still disappointed by the drop in upload speed, but the improvement in the download gives me confidence that the upload speed may be fixable too.

hggomes, thanks again for this firmware fork and for your help so far.

 

[cyborgpunte]

Love this fork, thanks @hggomes

But atm on Merlin again, adding this to compare with:

To my \\RT-AC68U\tmp (CIFS) with Merlin 378.50_ta (CFE:1.0.2.1modded)

UL 62,4 DL 41,2 (Mbps) meusered with "LAN Speed Test(Lite)"

[hggomes]

FACTORY DEFAULT RESTORE and manual configuration from scratch is the key, probably you guys are restoring old config file to the router.

 

[faur]

Dears,

someone can PM me a link to hggomez final firmware for ac87u please? (presuming that the tx power will increase, that will help me a lot!!)

Thank you in advance!

Update: Thank you a lot!!! (y)

Feedback of minimal value of transmitted radio power

Maybe i should set the minimum value equal to stock, give me a feedback and i will decide on that.

Because increasing transmitted power is not the panacea, how about setting the default value equal to stock so that the user can either increase or decrease his WiFi router's transmitted power as he needs?

 

[noric]

Could you please PM me the RT-N66U firmware?
Thanks.

Update: thanks for the Pm.

 

[gedesby]

I would be happy if someone could send me a link so that it also can be tested in the southern part of Denmark.

And hggomes don't let anyone tell you whats wrong and what's right you know. Don't let others make yours choice

 

[nonolk]

Hello,

May someone send me a link for this firware for ac68u.

Thank you in advance.

Hi,

I have a strange problem with the firmware.
the next day I lose the port forwarding.
I have to click applied for it working again.
I erased the nvram before installing the firmware.

 

[hggomes]

Hi,
I erased the nvram before installing the firmware.

Before?!??

------------------------------------------------------------------------------------------------------------------------------------
MANDATORY:

- FACTORY DEFAULT RESTORE (http://ROUTERIP/Advanced_SettingBackup_Content.asp) is required AFTER FW upgrade.
- DO NOT USE/IMPORT OLD CONFIG FILE AFTER FLASHING, just configure it manually from scratch.
------------------------------------------------------------------------------------------------------------------------------------

If it doesn't fix it, give it a try on RMerlin FW or ASUS stock, you will see the same scenario for sure, it's the same code.

 

[kasz]

Yesterday I performed this firmware update and change was night & day.

What I did not performed was a factory default restore after install, but only with the upgrade change was noticeable. I will try to perform a factory default restore this afternoon.

Many thanks for your fw!

 

[mdm-rulez]

First of all, thank you for your efforts HGGOMES.

May I have RT-AC68U FW links, please?

Thank you.

Hi,

I erased the nvram after flash but I have the same problem.

I lose port forwarding after some time.

I have to click apply for it working again

I have this in my log :

After click on apply :

ifconfig :

What is the output from: iptables -vnL
Before and after you lose forwardning?
Do you use any own iptables script?

 

[stefauresi]

hi,

no scripts

I erased the nvram after flash but I have the same problem.

Have you erased nvram or factory default restore via webui?

Have you configure it manually from scratch after or you have imported an old config file?

Please describe exactly what your steps after flashing it.

You can't actually see the rule there can you? You need to see the prerouting table instead, that's where you will see your rule from port 80 going to 192.168.1.20:81.

iptables -t nat -L

I've noticed you are using pppoe connection, normally ISPs disconnect/connect/redial after 24-72h, you will have a new IP after, see if after you loose the firewall rule on the router the ppp0/wan IP change.

[hggomes]

Have you really read all my questions? It would help if you could answer them or we will get nowhere...

That's the rules you need to check after loosing the firewall rule:

Chain VSERVER (1 references)
target prot opt source destination
DNAT tcp -- anywhere anywhere tcp dpt:www to:192.168.1.20:81
DNAT udp -- anywhere anywhere udp dpt:www to:192.168.1.20:81

Also you must tell me what's the reason for having DMZ and a forward rule together running on the same machine, that's the issue here.

 

[stefauresi]

Webui

Have you configure it manually from scratch after or you have imported an old config file?

manually from scratch
