Title: Advice on first modem
Post by: Adam1V on February 14, 2021, 04:43:59 PM
Hi guys, first time poster here.
I’m looking to break out my broadband connection using a separate modem and UniFi UDM Pro.

Currently using Sky VDSL 70/20.

I had originally settled on using a Vigor 166 however a few posts on here are suggesting the firmware is not particularly stable.

Just curious if anyone has any suggestions, is the 130 a decent and stable alternative?

I would say depends on your cab type if you know it?
I use vmg3925 in bridge on eci cab. I want the real time line stats. They are cheap and very stable. Easy to get supervisor access too

Hi guys, first time poster here.

Welcome to the kitz forum.  :)

As above . . . If you are interested in the circuit statistics, one of the ZyXEL VMGnnnn-B10 series devices should serve you well.

Where can I find the cabinet type?

Just looked it up, and slightly puzzled as it’s listing FTTC is unavailable to my phone number and postcode when it clearly is?

Ah, that data comes from the SamKnows website and, unfortunately, is horribly out of date. So you are located in the area served by the Midsomer Norton telephone exchange. If you know the primary cross-connection point (cabinet) number, it is fairly easy to lookup the details on the Magenta Systems CodeLook website (https://www.telecom-tariffs.co.uk/codelook.htm?xid=533765&locality=13447).

The good news is that Huawei cabinets have been exclusively deployed in the Midsomer Norton area.

Looking via Google Maps Street View (https://www.google.co.uk/maps/@51.2780368,-2.4737166,3a,37.5y,81.01h,82.19t/data=!3m6!1e1!3m4!1sfwYiHzZ6MCeK6SS881jdHw!2e0!7i13312!8i6656?hl=en), I am fairly certain that is the "fibre twin" to SSMID P3 (https://www.google.co.uk/maps/@51.2782963,-2.4735661,3a,15y,244.35h,86.1t/data=!3m6!1e1!3m4!1sRsNUH-PdM0XhBUU7fMdMtg!2e0!7i13312!8i6656?hl=en).

Sorry for the daft question, but what is it with the Huawei cabinets, are they out performing all others?
After doing a lot of reading on this site, I think the ZyXEL VMG8924-B10A appears to be a wise choice of modem, set in Bridge mode?

Nice. Will be passing it in the morning heading for westfield... I would opt for a broadcom device and not a draytek given your vdsl cab type.

8924 bit old now. Try a vmg3925-b10b

Huawei cab has better options than eci. 3db profiles, g.inp as an example, vectoring (on some)

It is actually the case of what is wrong with the alternative infrastructure cabinets (with ECI electronics) that were deployed for the FTTC (VDSL2, ITU-T G.993.2) service. Given that is was just a binary choice, the elapsed years of deployment have shown "Huawei good", "ECI bad". (With apologies to "Snowball" from George Orwell's novel, "Animal Farm".)  :D

8924 may be a bit old, but if you're just using it as a modem, then I find it great.  I've recently moved from a draytek to 8924 to match up with broadcom in the cabinet using an 8924.  Very happy with it.  I am lucky to have a very good line - max attainable rate for me is 115/25 this morning and I get 80/20 with SNMR of about 15db each way, but it's been completely solid, and the dual port setup to enable monitoring using dslstats is very nice and simple.  All in all, turn everyone off (wifi etc.), set it up as a bridge, and you're good to go.  And, of course, it has the added advantage of being available for about £10 on the auction site of your choice...

After a load of fiddling, i also got the voip ports to work when it's in bridge mode, it's £10 buys you voip as well...

I myself should start thinking about using VMG 8924-B10A units, as they are cheaper than the VMG1312-B10A devices I’m using now. Can they still be bought new, boxed?

Consider putting the Johnson (our very own kitizen) firmware in them so you get PPP MTU 1508 and the functional enhancements including the ‘easy stats’ (as I have termed it) built-in web server. See https://github.com/johnson442/custom-zyxel-firmware/releases (https://github.com/johnson442/custom-zyxel-firmware/releases)

I'm using a Draytek Vigor 130 with my VDSL line to Unifi USG3 and USG4Pro, and it has been bulletproof.  If you use it as a pure modem (ie with PPPoE being handled in the Ubiquiti router) there are some Unifi config hoops you have to jump through to get SSH access from the LAN onto the router; these may not be possible on the UDM Pro as from what I understand they removed the ability to edit the JSON config manually.

Web stats are pretty limited from what I recall.

For reliability I can recommend a VMG3925. Mine has not been rebooted for 307 days and the DSL connection has been up for 47 days.

VMG8324-B10A would suit too as it's the same unit but without 5GHz WiFi. Both have the noise filter on the DSL input like your beloved VMG1312-B10A. They're not available new but new old stock units do crop up quite often on eBay.

Yep - I bought a couple recently on ebay - one NOS and one just lightly used.  No warranty etc., but that's they I bought 2 - just in case.

Ive managed to find a 3925-B10B off ebay, new and unopened.

Currently just playing around with it and exploring menus, it's not immediately obvious that I can use it in modem/router mode to connect to Sky Fibre Pro (MER Option 61), is that expected? I can only see PPoA for ADSL and PPoE for VSDL. I've tried using suggested abcdefgh@skydsl and a few numbers for a password, however I think it needs to be set to MER with a client identifier ID and Vendor class ID Inputted, which isnt visible.

To be honest, i dont plan to use it in this manor, it'll be set to bridge mode and i'll be using a seperate router however i wanted to connect to the internet with it and just have a play as well as update the firmware.

I cant find what firmware version its on and 'Firmware Update' isnt an option from within the maintenance menu but for now ive assumed that might be visible once an internet connection is established.

It is indeed not obvious, it involves manually setting a VLAN that connects the VDSL virtual NIC to an actual physical port on the router, thus making a bridge.  But this is exactly the same way any router turns into a bridge, it just has to be done manually on these units.

Post by: Adam1V on March 03, 2021, 06:36:55 PM
Thanks for that.
Still slightly confused so apologies if these are daft questions but if I get this straight;

1, I need to setup one of the physical ports to be part of a VLAN
2, In the WAN settings for VDSL I can map the connection over to said VLAN
3, I physically connect the blue WAN port to the Yellow VLAN port and it should be good to go?

Should the VDSL settings be set to router or bridge mode?

Thanks in advance.

LAN1 becomes the Modem/Bridge port, you connect it to WAN on your router.
The only difference here is that as you are with Sky you need to use different settings on your new router, DHCP rather than PPPoE.  This is discussed in another thread on the forum somewhere.

Further instructions are for setting up a second port to be able to still connect to the UI for reading statistics.

I use the 3925's..more than likely partially locked so you cant see the firmware or supervisor password. Fairky easy to crack this. There are a few threads on this or happy to help you if required.

Just needs configuring in bridge mode. Can send you screen shots if required. I would get it unlocked so you have full access to all menu's/settings..

Some of mine are ex Kcom which I unlocked. I have one on a sky vdsl setup on bridge on another line too

I might be confusing matters here, but currently I do not have a router. this is on the way.
I understood I could use the 3925 as a combined router/modem (literally only just to get online, play around, nose through menus with), is this feasible?


I note, once the router arrives, this will connect to the WAN port and the connection will need to be set in Bridge mode.

I have admin access (username admin, password 1234), however firmware options still not visible.
Will I need to reflash using TTL cable?

Thanks

 You just need the output of cat /var/passwd file then use hashcat to crack the supervisor password. My gpu takes about 12 mins to do it. I do find the older version of the firmware makes it easier.

Not sure if it still warrants unlocking, but just found if I login with a newly created user account (non-admin) it displays the full menus as well as the firmware upgrade.
