@GigabitEthernet the VMG 1312-B10A modems have performed well for me compared to my previous (DLink) modems, 5-10% improved downstream sometimes but at higher SNRM and greatly improved reliability. Upstream is slightly worse than the DLink modems, which is a nuisance. This is all over ADSL2 though so be warned, your mileage may vary.

I think you've misunderstood my post.

No problem, Weaver.

I will flash johnson's newer firmware right away.

The firmware I am currently running - "1312-B10A-from-zyxel-jumboframes-3925adsl_phy" - is very unstable and my modem has dropped twice in 24 hours. The Internet feels less responsive with this firmware and less reliable, than with my Huawei HG612 which would stay up for weeks!

Any idea how hard it would be to patch in the SNRM graphing into the VMG3925-B10B firmware?

I really didn't want to have to compile it myself, but I'd also like to re-enable the administrator passwork sync functionality so it may come to that if the original person who compiled it is too busy.

I hope not hard at all, I now have a 3925 to test and will want the graphing working before doing so.

About the copying of admin to supervisor password that was present in that github repo then removed. Copying it over every 60 seconds is certainly an option, but when the tools to crack and change the supervisor password permanently without firmware changes are available, isnt this the best option?

That firmware uses the x1 adsl_phy, so I would be surprised if the x6 one offered improvement, but excited if it did.

Another thing to try would be a much older firmware with different adsl_phy and kernel module. Will look up what the other user I mentioned found to work.

As for the perception of "slower" internet with the zyxel, I can not suggest any reason this would exist. Its possible, but I have no idea what would cause it. Did you ever sort out how to set the ports on your archer correctly under OpenWRT to get 1500 byte MTU?

Compared to having it work automatically in the firmware?  Not really.  Every time I think of sorting it out, I forget exactly where the most recent instructions are on the forum, thus I haven't done it yet. ;)

It only really needs copying over once, at boot, or included in the password changing script so it happens when you change it via the UI.  I'd look into it, but I'm really wary of flashing any firmware that someone else hasn't already checked works as I don't have a spare for testing.

Firmwares for 8924/8324 based off the new AAKL.24:

Is anyone able to confirm this is the latest/correct location of trusted firmware for Zyxel 8924 B10A with 1500 MTU support when running in bridge mode and multiple telnet sessions?  Thanks

I built one using AAKL.28 a while ago but never got round to sharing it. It has the jumbo frames patch and nothing else. Not sure what the multiple telnet session fix is, but I didn't bother since I have no use for it.

"using AAKL.28 " really? Good news if so, I thought we were still waiting for the sources to be released (6 months was quoted).
Care to share it mate?

Here you go: https://www.dropbox.com/s/hvy0m087809zphe/VMG8324-B10A_1.00%28AAKL.28%29C0_RFC4638.bin?dl=0

I'm running it right now, so it works but use at your own risk and all that :) This firmware has only been tested/used in bridged mode. In routed mode, YMMV.

This only has the jumbo frames patch, nothing else has been touched.

For reference this is the best URL for the AAKL24 version of these firmwares for VMG1312-B10A and VMG8924/8324-B10A it explains what firmware does what.

https://forum.kitz.co.uk/index.php/topic,21545.msg381478.html#msg381478

Does anyone know if there is any real problem these being for AAKL24 instead of the more recent AAKL28? 

The ability of multiple telnet sessions, jumbo frames and custom commands is one of the reasons I want to try this firmware.

Thanks

Have a look at the change history (listed in the PDF in the firmware archive file) and decide for yourself.
