Zyxel VMG1312-B10A uptime.
« on: September 03, 2020, 08:06:05 PM »

I have been having PPP drops on my Asus RT-AC68U so I converted it to a wifi AP and turned my ZyXel VMG-1312-B10A into a router which was being used as a bridge modem. I have 3 Zyxels and earlier in the year PPP was dropping so I swapped out the modems and it stopped. But recently it started happening again so I reconfigured the Zyxel as a router but it dropped at 8.34 this morning. I have a script to download a 1gb at 32 minutes past the hour every hour and the ZyXel was fine up til 8.34 this morning. It usually gets to about 800mb downloaded and then the PPP drops and its very random.

I have swapped the Zyxel with a 3rd 1312 and it has been fine all today, further testing needed. I have been talking to my ISP and they want to send an engineer but I doubt they will have the skills to diagnose this type of fault as it only drops when under load. Could it be I am not powering off the Zyxel often enough?

Sounds like you need to change to a good ISP if they can’t sort this out for you. You shouldn’t be powering the ZyXEL off ever, of course.

Well Ive swapped to HG612 to test. The Zyxel was up 2 months almost before my line started playing up.

Uno are one of the best.  Maybe not quite in AA's league, but probably the best of the rest and have already offered Tim an engineer visit, so don't think they are doing much wrong.

I agree they got BTO to dig up my drive for a new cable gratis.

So my PPP session dropped 3 times today under load, ISP is contacting OR to send an engineer. But even their own session history says "Port error" when the line drops so I am hoping for a port swap although DSL is rock solid with HG 612.

Well this is getting frustrating. Uno are saying that port error in their session history could be anything. This has been going on for months and I have sent numerous routers back as faulty due to this PPP session disconnect fault.

I have now tried numerous makes of router and modem and it does it with all of them. Uno are also telling me it is unlikely OR will do a port swap or lift and shift as they term it as the line is likely to prove clear. It's like I dont exist and my swapping of routers counts for nothing. I am now using BT OR modem and Asus router with default settings which countless other users must be using successfully. Now considering A&A.

To be fair, if your line stays in sync it seems unlikely its a problem with the DSLAM port.

This is a frustratingly difficult problem to diagnose and switching ISPs could very well be the best option, as it would eliminate the ISP as the problem. (as its the ISPs kit your PPP session is terminating on so perhaps where the problem lies)

Notice what AA say port error refers to: https://support.aa.net.uk/Line_State_Colours
"L2TP relay failure, or L2TP tunnel level close"

Thanks for that Alex. I have never tested the line this hard before but I suspect this has been going on a while. I have now reconfigured my ZyXel as a router as I really didn't test it hard before and the Asus as AP. A&A is on my list to change to if Uno cant fix this.

AA also has this ‘fix your line in a month’ deal where they will take you on with a fault and will even give you your money back if they can’t fix your problem in a month.

Thanks for that Weaver. I wrote to Openreach CEO on Saturday and today a Network specialist called me who will own the problem until it is fixed he said. I will keep the A&A option in mind. Only trouble with A&A is they have fixed limits which I might go over downloading 1gb every hour to test the line.

Edit: Emailed A&A support for an opinion.

I am a longtime AA customer, and I don’t have fixed limits. No quota. I use their ‘units’ tariff which has no limits; you get charged for what you use downstream (on fixed lines, only downstream packets are charged; upstream is free). You can use what you like and it’s slightly cheaper if you pre-purchase ‘units’ of download bytes. Units tariff is very expensive in the daytime mon-fri but incredibly cheap overnight 02:00-05:59 BST.

You don’t need to download huge amounts to test the line with AA; and it would bankrupt you. AA continually tests the line every few seconds; measures the latency and checks for packet loss: See https://support.aa.net.uk/CQM_Graphs You get pretty pictures that show you the line performance minute by minute and also show your traffic usage.

That's the trouble I do need to download 1gb per hour as that is when the fault occurs. That looks way to expensive when I put my useage in the calculater. Uno's unlimited option gives me less worry.

I've just had an email from the Chief Engineer at Openreach noting some problems with routers in bridge mode. It was not addressed to me, merely a CC but will be interesting to see what the Network Engineer comes up with.

Also a thought had occured to me, with OR updating the Line cards what if the VMG-1312-B10A is no longer compatible with the OR linecards/dslam. I have a VMG-1312-B10D on its way to me hopefully which is on the current OR approved list.

His issue is his PPP session terminates when he does large file transfers.
He needs to run large file downloads to replicate the issue.

Uno run practically identical  line monitoring to AAISP.
An example of this from Bangers line is attached.
I actually prefer how Uno display the data.

It's just a Broadband Quality monitor which you can setup for free on ThinkBroadband, who use a FireBrick FB6000 series ping box like AAISP.

Going by the TBB thread Uno have progressed the ticket within a few hours.
Matt himself is keeping an eye on the ticket and I'm sure they'll get to the bottom of it.

The answer isn't always switch to AAISP.
Their cost for what is a metered service is ridiculously expensive particularly for those who consume large amounts of data.
Banger would use over 37.5% of their largest monthly quota running his hourly tests alone.

Uno are a good ISP and given the proper time to investigate the issue will likely get to the bottom of it.

Every 4 hours so far as I can tell.
