I've had an ongoing problem for months and months with our Vodafone broadband connection

Every time we upload a file (ie: when I take a photo and my phone uploads it to google photos, or if my wife is uploading photos to a greeting card making website) , after the file is uploaded our internet connection stops working for 5 to 15 minutes

We're on an ASDL connection, which is the fastest line available at our location (we live at the edge of a small town)

I had a support ticket about this 4 or 5 months ago, they performed a 24 hour monitoring test and told me...

Upon investigation we could find no fault over the network. There is no data loss or delay that we could find as well

I’ve noticed that your upload speed has been maxed out. Once there’s a high usage of the upload speed, it will affect the stability of your download speed, that will result to disconnections

For the meantime, you can try to do a factory reset on the modem by pressing the reset button/tiny hole at the back for 30 mins (you can use a pin) to refresh the modem, and moving forward, kindly balance the usage of your upload speed as sometimes it would take time for the connection to be back on track.

So their advice is to "balance the usage of your upload speed", but I have no idea how I can do this. We aren't doing anything out of the ordinary with our uploading, it's really mainly google photos and sending photos and videos via whatsapp etc

Does anyone else's internet connection work like this? If there's nothing that Vodafone can do, I'm going to have to switch to another provider. Our internet cutting our every time we upload a file is massively annoying

It's perfectly normal - switching provider will not make any difference. Upstream saturation is your problem - as you've discovered, if the connection is maxed out in one direction, it affects the other direction as well, particularly on a slower connection.

It may be that your connection can be improved though - can you post the modem DSL line stats?

i used to see this on my vodafone link. In this case, heavy load over DHCP was trigging some sort of an automated system.

Vodafone's end would stop routing until a new DHCP renew (5+ min delay).

I've since implemented a solid QOS policy that avoids hitting this.

Assuming the above is not the issue your suffering from and your actually getting fully no transfer until the session restarts then their point is completely valid.

Simplified, you've got two lines - an in, and an out. Someone hogs the out line, you can't send out a request for more stuff to come in. When a device is slamming your outbound, nothing else can reach out to ask for the next thing in a sequence, or an entirely new thing, so everything grinds to a halt. You'll need to investigate alternative technologies to ADSL if you want to resolve this issue - 4G Wireless through Vodafone, Spark, or one of their many resellers, or maybe a local ISP offering actual Wireless could help get you more capacity.

Anything I say is the ramblings of an ill informed, opinionated so-and-so, and not representative of any of my past, present or future employers, and is also probably best disregarded.

That's an interesting (and yes, annoying) problem. Mind PM'ing me an account number so I can take a look? Curious to see if you're dropping either DSL or PPP/DHCP. Also what router are you using? And do post your line stats as @RunningMan suggests.

RunningMan:

I'm not exactly sure if this is what you're asking for, but the following is what I see when I log into the router on the Maintain> System Information > DSL section...

DSL synchronization status: Up

Connection status: Showtime

Upstream line rate (kbit/s): 856

Downstream line rate (kbit/s): 8937

Maximum upstream rate (kbit/s): 984

Maximum downstream rate (kbit/s): 10516

Upstream noise safety coefficient (dB): 6.9

Downstream noise safety coefficient (dB): 6.3

Upstream interleave depth: 0

Downstream interleave depth: 0

Line standard: ADSL_2plus

Upstream line attenuation (dB): 24.6

Downstream line attenuation (dB): 44

Upstream output power (dBmV): 10.6

Downstream output power (dBmV): 0

Downstream interleave depth: None

DSL up time: 0 days 3 hours 1 minute 13 seconds

I've sent you my account number

The router is a HG659

This sounds like a really promising idea. It makes some sense that if i had a way to limit my uploading bandwidth that it might sort things out

I've had a look through the modem (HG659) admin page, and can't see anything that looks like an option to do this

Most of the uploading is done from our phones, and I can't see any way to limit our upload speed on them without rooting the phones which I'm not keen on doing

Is the firewall setting in the 659 active?

Naked

I don't think so, yesterday was the first time that I had ever logged into the router so everything is just set to their defaults

@teamsteve do you have a dedicated xDSL jack point the modem is plugged into and are you still using line filters?

I think that the model is just plugged into the phone jack, and there's a filter between the modem and the wall jack

I don't know about you guys but I had ADSL for many years, routinely pegged out the upload for hours (sometimes days) at a time and never once experienced anything like this. It's normal for the connection to be pooched while you are uploading, but fifteen minutes after the transfer has finished? Can't see how this could possibly be anything on his end.

That said I agree that you could probably fix the problem with some smart router software/QoS. Shame the HG659 doesn't have this functionality. I know most of the third party ones allow you to do it - I've done with both Tomato and Gargoyle. You could grab a cheap device that supports one of these firmwares, limit the upload to 90% of your sync speed and see if that does the trick. But really I don't see why you should have to do this at all - it sounds like a Vodafone problem.

@teamsteve lose the line filter and just have the modem plugged direct into the jack point and how many jack points total do you have in the house?

Yea, I'd totally understand if I couldn't upload while downloading. It'd still be annoying but it would make sense

Yea I might have to look into getting my own router, that's a good idea. That sounds like that would achieve Vodafone's advice of "kindly balance the usage of your upload speed" I suppose

Agreed :/

I'll try that tonight. We have 2 or 3 jack points I think

It's this detail that directs me to the point about DHCP nulling rather than congestion from utilization related.

Exact same as i was seeing back when i first moved to DHCP.

Unfortunately for me at the time, Vodafone did not support it. i'm unsure if they even now support 0.110 DHCP officially.

I also saw the issue occurring with Downstream traffic, although moving from 2mbit to 17mbit to resolve this.

@teamsteve you need to isolate all the other telephone jack points from the jack point the xDSL modem is plugged into, Make sure modem is plugged into master telephone jack point as well

You may need a different lead as well to plug the modem direct into the jack point to remove the line filter
