I have so far been unable to load and test this firmware (AAKL28), as I am still in the first week of line training after I moved ISP and DLM was reset...

I've made a firmware for the VMG8924-B10A if anyone wants it. Based on the latest 1.00(AAKL.21)C0

http://bit.ly/8x24Jumbo

can you please do one for VMG3925-B10B? thanks.

Ideally based on V5.13(AAVF.7)C0

Here are firmwares compiled from zyxel sources, the ...jumboframes.bin ones have only the patches from Olipro's repo and the 3925 ones have the updated A2pv6F039x1 xDSL driver vs A2pv6F039v version in the latest ones from zyxel.

I have tested all to boot with a serial console attached and none make any new warning messages. I have only used the 8324 with new xDSL driver on my line and it worked fine several hours before I pulled it to test more.

https://www.dropbox.com/sh/jw4pdc3yem4zzaa/AACVBARaPKaEemeeJ8hP87J_a?dl=0

I own an 8324 but these are for the 8924 not 8324.

Ideally I want to use the 3925-B10a tho as its smaller, looks nicer and syncs with less errors than the 8324.
Edit: To clarify these are all based on the latest version of each, the VMG8324-B10A_1.00(AAKL.21)C0 & VMG1312-B10A_1.00(AAJZ.14)C0

Johnson may already have the source from Zyxel for this but I'll request it from them anyway.

They usually respond quickly but have held back brand new firmware for a few months recently.

A new version of the VMG3925-B10B firmware is now up on:

https://github.com/trejan/VMG3925-B10B

This contains (i) the jumbo frames patch; and (ii) a mechanism to sync the admin user password to supervisor + root.

many thanks, hopefully this newer firmware has same sync performance as my current one.

jhm has done it, as soon as DLM puts me on fast path I am flashing (DLM reset after aaisp migration).

Thank you, but please go ahead, just in case it doesnt work properly :)

I have AAJZ17 for the 1312, AAKL28 for the 8x24 & AAVF13 for the 3925. Been meaning to get around to building the various telnetd/x6/stats versions for each device and flashing all to test.

Also have dockfiles and helper scripts to build on all platforms with just a working docker install and a few commands, need to clean them up and put them on github.

In the meantime any specific version anyone would like? I think underzone mentioned an 8324 with jumbo frames and x6 adsl_phy, others?

Anything of note between AAVF.12 and AAVF.13 on 3925?

There are quite a few changes but nothing really jumps out if you are using them in bridge mode.

Edit: Scratch that, didnt notice the DSL driver is updated from d26s to d26u, that would be of note but I'm not sure of its impact.

In that case I'm interested as I can always try it on one line only, see how it fairs.

I wonder what " [eITS# 180800775] Detail information when CPE sync up DSL." is about?

I also see WLAN memory/resource leak, which could explain why when I tried testing WiFi I would get random lockups.

I am waiting for my line to stabilise due to interleaving being applied but when it is sorted I plan on upgrading to bridge mode on my 8324 and a new separate router. 

I'm hoping to use the jumbo frames and multiple telnet features so an update would be great.

I was however planning using the firmware with custom commands also just in case I need it in the future.

Not sure if this would save time but why have so many versions why not just have the fully featured version with jumbo, telnet and custom commands and then that in std, x1 & x6?

Thanks for creating these firmwares I for one are certainly thankful.

the newest jhm firmware seems good from initial impressions, no issues flashing through GUI, and it also defaults to 1508 so you dont even need to run the commands or edit anything on the modem.  I have confirmed from tests (after adjusting aaisp control panel settings and pfsense) that I do now have a live 1500 byte mtu on pppoe.  Thanks to everyone involved in the work on this.

--edit--

Some notes on the new firmware.  These issues are not related to the patch I think.

On this firmware zyxel overhauled the UI, its not good.  But the more concerning bits is what else I noticed.

The modem was powered down to send a dying gasp to dslam, dsl cable unplugged, and then I powered back up and flashed, I then waited 3 15 min cycles, and powered it down, then plugged dsl cable back in and powered it up.

On dslstats it logged 3200 ES which is very close to the dsl downtime.  I dont see these ES anywhere in the telnet data so it is odd, but I have never seen that behaviour before when doing this process on older firmware versions.  I do wonder if the modem now saves its stats on shut down to its storage so it can remember it, but as I Said I dont see it anywhere in the telnet data.

Also just to check if I am not going senile I looked at dslstats to see the modem uptime, but thats now "not available" so some things have moved around as well that affects the monitoring.

We will find out probably within a day if this becomes a DLM issue as 3200 exceeds the daily threshold, my feeling is only the stats "since link time" are passed on.

Yeah I see this which is modem uptime, and they also not there and confirm I did power down when I said, so no idea where dslstats got this 3200ES from.
