High Volume of Upload Data causing connection drop

Jamesdtl — Tue, 14 Mar 2023 22:05:01 GMT

Hello! This issue is well reported on here but seems to be a limited number of cases for those who need high-volume uploading & a constant amount of bandwidth. Sadly we are one of those homes.

We are uploading regularly at full speed to GoogleDrive, we see good speeds for most the time ten minutes before the connection is cut. We have a Smart Hub 2 but removed it due to bad wifi performance for an ASUS router. The issue remains on both devices.

Looking though the forums sounds like the moderator team have a way to contact the connection team for them to change the system slightly for this use case so hopefully I can get that done!

Please let me know what information is needed to be clear on the basic trouble shooting we've reset, rebooted, replaced the router in the home to check what the issue is and the issue remains. We have used a traffic limiter on the ASUS router which does stop the issue, limiting to 75mbps overall so it's something to do with been at full speed for a period of time however it's regularly causes our network to drop now as we need the full speed.

Thanks, looking forward to replies!

If you are regularly uploading high volumes of data I politely suggest that a service other than a consumer grade residential one would be more appropriate to your needs.

Thanks for the reply! Sadly it's the only service that exists nearby us - we did have Hyperoptic in the past however not in this area. To be clear it's backups of HDDs, game files, photos etc but even as a consumer product it shouldn't cut out every 10 minutes of uploading.

I mentioned the high usage as it seems to have been raised before and solutions given by the BT team, thought the additional context of the uploading might be helpful.

I would reccomend using an upload manager and limit to about 80% of your upload bandwith, saturating your upload will effect your connection.

@Jamesdtl

Changes were made to the configuration of the home hub to restrict the upload speed so that the equipment in the cabinet did not drop the connection due to too much data overloading its input buffer.

As you are not using a home hub, that is something you will need to implement on your ASUS router, or elsewhere on your network. What broadband package do you have?

There is nothing the moderators can do on your own router.

Maybe use a NAS for your backups instead.

Hello! So the issues we see are normally at about 95 mbps a second consistently for more than 10 minutes! running a speed test we can get 115, it’s the top FTTP package.

It happens at a point where we might not even know uploading is happening, it might be happening in the background and then the entire network will go down for say 2 minutes. It’s strange as I’ve had the same package in a different location and didn’t experience issues, on the same router. So it feels to be like something could be adjusted.

is it expected behaviour, after 10 minutes of uploaded the entire network would drop? I checked the ASUS logs and it looses the connected from the WAN unable to connect.

Thanks

How much data are you backing up & how? Sounds like your backup strategy may benefit from switching to incremental, so you only backup what has changed that day.

The amount of data is maybe 10GB nothing crazy, as I say it drops consistently after about 10 minutes of uploading at full speed so the amount of data actually going up isn't much.

The connection from the WAN fails and then reconnects after about 15 seconds in the log of the rotuer.

@Jamesdtl

You need to restrict the upload rate, as the BT end cannot handle the speed and is dropping the connection when the input buffer overflows.

There is a network setting on Google Drive to do this.

Thanks for the reply!

What is the input buffer, I know that's a technical question just interested. How come to BT can't support the given upload rate, you'd assume if they supply 110mbps upload it would be able to maintain that rate?

Thanks in advance!

Very simplistic answer.

Every router has an input buffer where it holds data until it can be upload or download to either the internet or your PC.

You PC will upload to your router at 1Gbpx but once the buffer gets full the router will tell your PC to pause until it has uploaded enogh data to make room in the buffer to accepct more this only takes milliseconde. Meanwhile the router is reciving data at 1Gbps but because the buffer may be full it camn't pass all that data on, for a short while you may get it but then it becomes so congested you get gridlock and everything comes to halt. Connection dropped, router clears the buffer and starts all over gain.

Hello! Thanks for the insight - that's interesting! I am using a RT-AX82U ASUS router which is fairly well spec'd at £225. Anything I can do with the WAN settings that you know of to help with this issue, sounds like it sits on the side of the router more than the WAN from what you are saying?
