VMG1312-B10A Unreliable, Alternatives ?


[link to this post]
 
I have recently been regraded to fttc from old fashioned ADSL and i'm using the AAISP supplied VMG1312-B10A modem. I disable everything on it like wifi/firewalling/upnp and use it as a fairly basic modem in routed mode.

I open up snmp from the LAN side and forward syslog back to the linux firewall facing it.

When in ADSL mode it manages to get to 3 days before crashing, now in vdsl mode it only lasts 2 days before crashing. Stops responding to pings, stops forwarding packets, UI unresponsive, needs a power cycle despite there being LED activity.

I'm going to try bridged mode with pppoe/pppoa (I haven't worked out which i need yet) but this means I need to change a bunch of addressing/firewalling on my linux firewall.

Has anyone else found this device to be unreliable and if so, what other devices have people used instead ?

Thanks

On FTTC I found it fine in pure router mode fed by my HG612, but no IPv6, and utter rubbish when I tried it in modem/router mode. Getting it to work as a pure modem was beyond me.

Finally I dropped it and the HG612 and bought a Billion 8800NL R2. Very pleased with it since installation on 17 December, only letdown is the wifi is only 2.4GHz. Which is no real problem to me.

Setting up dual band IPv6/IPv4 took me a couple of hours or so but has been rock solid since.

I have a software tunnel from the linux host to endless, the modem isn't talking ipv6 at all.

I think i can work out ipv4 and pppoe, but at that point I guess i'll be seeing native ipv6 hitting the ppp interface which i currently terminate with tun0 and I'm not quite sure how i reinstate ipv6 on a ppp interface.

I also do wireless elswhere in the network, i disable that in the VMG1312-B10A.

Thanks for the reference to the BIllion, I will look it up.

Anyone else have any other alternatives ?

If you don't mind using a 2 box solution, then consider the excellent Draytek Vigor 130 hooked up to any standalone router. Otherwise something like the Tplink VR900 would be good also.

I am not sure what you mean by a 2 box solution.

At present and previously i have used the zyxel modem in routed mode, where my /30 ends up on an interface of my linux firewall and the router has its own /32 address on it's external interface as it's running its own pppd talking to A&A.

I have the option of putting the zyxel into bridging mode and using it purely as a modem, and having the linux host run the pppd talking to AAISP. The external IP currently on the zyxel moves to the linux host.

I think i either will be using a modem/router (a single box, as it is now), or the same, single box as a purely modem.

Why do I need a second box ?

Using the information from https://support.aa.net.uk/VMG1312:_Bugs I have the VMG1312-B10A almost perfectly (FTTC and modem and router). The only issue is if there is a remote loss of the PPP session IPv6 fails and I have to do a full reboot of the router (as documented on the support page). Apart from that issue it's fine.

I've actually found I'm getting a more reliable connection than I was with the HG612 - I had an issue with my central heating - when the hot water thermostat turned the boiler off I frequently found the HG612 lost sync. That hasn't happened at all with the ZyXEL.

On a Huawei FTTC cabinet the Vigor 130 I had made a complete mess of the connection. Heavy banding resulted, not yet fully removed but vastly improved after three days of the Billion.

Irrelevant though to the OP I gather, who is on ADSL2+.

Mine didn't play that well I'm afraid. When used in modem/router mode it was highly unstable so didn't hold IPv6 for more than a day or so.

2 box solution = xdsl modem + standalone router.

Personally this is what I prefer, a standalone router is far more powerful than a combined unit, you can do things like run a OpenVPN server on it (with the right fw) and best of all, you can reboot the router as often as you like without messing up your sync rate.

Ok i see. What you're referring to a "standalone router", I use "Linux machine".
Does ipv6 termination, firewalling, vpn endpoints, dhcp forwarding between its private interfaces.

Umm, no, i was on adsl for years and was regraded on Jan 3rd to fttc. (did you read the first post ?).

The old adsl zyxel was good as gold, would stay up for long periods (months/years). This xdsl one is rubbish so far.

What do you mean by "heavy banding" ?

Ok - I'm not willing to put up with a router which requires a button off reboot regularly. I have the modem and a number of associated linux hosts on a UPS in a fairly inaccessible part of my loft and going to visit the modem to hit the button is a major inconvenience.

When the modem gets rebooted in need to reinstall my firewall (I think it's doing some preventative arp-y type thing) but the v6 tunnel appears to survive the modem reboot without needing a restart.

[re: gavsdavs] [link to this post]
 
I got a bit confused in my memory of your opening post re your use if ADSL then FTTC. The fact yo are now on FTTC in fact makes the rest of mine more relevant smile.

Banding is what Openreach DLM uses instead of changing the sync-time noise margin in the way the BT Wholesale one does on ADSLx. See BT SIN 498 Section 2.2.1.

For some reason unknown, early'ish in 2016 60000kbps banding was applied to my line. In November/December I decided to change my kit for a few reasons, but a number of experiments caused that to be lowered to 55000 then 49000. The Draytek Vigor being directly involved in the drop to 49000kbps.

In the evening of December 17, as I said earlier, I got this Billion working. However unusually DLM lowered my banding again at 10am next morning to 45000kbps. Changes atre usually made overnight.

Satuerday>Sunday night it jumped it straight back up to 55000kbps, where it still is. Now a month on, and I'm hoping in another 4-5 weeks DLM will remove all banding. That's the sort of timescale it seems to work to when easing off. My Max Attainable is well over 66000kbps, where with the HG612s it was always below 60000. Which made the original 60000 banding very odd in the first place, as the sync was a solid actual 60000 as a result having never reached 58000 before.

Re your setup, I assume you realise it should be PTM not ATM, but you say you are unsure re PPPoA/PPPoE. It is PPPoE for VDSL2.

[re: RobertoS] [link to this post]
 
Thanks for the background on Banding, I will have a read.

With regards to line speed, this Zyxel does a very good job. The cabinet is brand new and currently filling up. It's about 300metres away and it's syncing at:
US=19999000, DS=79999000

However I can't live with a modem/router that falls off the network and requires a visit to get it back.

I've just ordered a Draytek 2760 to go in its place which I hope is more reliable even if it does deliver slightly lower sync rates. I will report back.

I really don't fancy having to run pppoe on my linux host, I did that years ago with the adsl frog and a series of PCI based ADSL modems. It was more work than a box doing modem/routing for you.

I've lived with 3mbit adsl for 10+ years, having 80mbits at the moment is a world apart.

As you intend to use the 2760 in bridge modem mode you should have just gone for the Vigor 130 modem as they both use the same vdsl2 chipset (Lantiq) and saved yourself a few quid. Another option would have been the Netgear DM200 vdsl2 modem which also uses a Lantiq chipset.

No, I intend to use it in routed mode, I don't fancy having to run a ppp on the linux host as that would require a load of addressing changes. I recognise the 130 is purely a modem, which is why i picked a 2760.

God you lot have such a dramatic internet life.

I just plugged in my HH6 got IPv6 and good wifi and it's been up forever. I admit I have a 8800NL for TTB which also just works for 4 but can be a [censored] to set up for IPv6

The old zyxel P660R i used for ADSL was great. could snmp it, syslog it, stayed up for as long as you want.
This new VMG1312 is a bit rubbish by comparison. The fact that AA run a bugs page for it kind of backs that up smile

And told me if I wanted a router that would handle their IPv6 I could buy another one, seeing as the ZyXel they sold me doesn't reliably do so. I was told it is a bug that they believe ZyXel will not be correcting.

All that will run AA IPv6 here from my vast collection of routers, is the Draytek Vigor 130 modem into the FRITZ!box 7930, which will even do the work of my WD MyCloud NAS and DECT base station, though no full dsl info. Did think about the same Billion as you Bob, but seems a pig to set up for IPv6, whereas the Fritzbox is plug and go.
