Line drops under load (random)


[link to this post]
 
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?

No. Assuming this is FTTC (VDSL) then you might need a different make of modem, there seems to be a problem with the Zyxel's on your line.

See if you can get a Huawei HG612 from the famous auction site.

I have an HG612 in the den but it is a bit slower on sync than the Zyxels, having said that this 3rd Zyxel is slower than the other 2. Looks like my next port of call is to try the HG612 and yes it is VDSL.

Each time you power off, the DLM thinks it’s fault. To keep the best speeds connect the 612 and leave it powered on for the next 7 days.

Right have connected the HG612 lost about 9mb/s speed but its worth a try. Testing for next 7 days.

Disconnected at 7.34 in the middle of a download. DSL on the HG 612 stayed up.

Very strange. Good that the DSL stayed connected, but the PPP disconnecting is one for your ISP I would have thought. Depends how technical the ISP help team can get, they may just tell you to use their provided router.

Also happened the other day with a ZyXel router, and again today at 7.34, 11.34 and 15.34.

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.
