So randomly throughout most evenings my internet just dies to the point its so slow.

Usually I get around 40ms when I ping 8.8.8.8 but when the fault occurs my ping times are usually around 3000-4000ms which makes browsing the internet impossible. Below is a list of things I've tried.

1. Unplugged everything from the network so only 1 device was connected ( this includes anything using Wifi) so I could run a ping test and the issue still persists.

2. I've just replaced the modem to make sure it wasn't hardware related but the issue still persists.

Usually the issue happened completely randomly and happens once or twice most evenings, there is no pattern in the times that it happens. The fault usually lasts 10-15 mins and comes right by itself. I haven't rebooted the router during the fault to see if reconnecting fixes the issue, I can try that the next time it happens.

I would be grateful it anyone has any suggestions.

Where are you - rural? Backhaul congestion?

More likely something inside your network saturating the upload, like iCloud or similar syncing.

You also don't say what sort of connection you are on - xDSL, UFB, 3G/4G etc.

PeterReader:

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

you have reset your modem and router
your PC (or other PCs in your LAN) is not downloading large files when you are testing - you are not being throttled by your ISP due to going over the monthly cap
your tests are always done on an ethernet connection to the router - do not use wireless for testing
you read this topic and follow the instructions there.
Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

Your ISP and plan
Type of connection (ADSL, ADSL2, VDSL)
Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)
Your general location (or street)
If you are rural or urban
If you know your connection is to an exchange, cabinet or conklin
If your connection is to a ULL or wholesale service
If you have done an isolation test as per the link above
Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

Is your premises phone wiring impacting your broadband performance? (very technical)
Are you receiving a substandard ULL ADSL2+ connection from your ISP?

@freitasm PeterReader has gotten lazy since John left.

Sorry, using ADSL in and urban environment. I had everything unplugged form my network apart from one machine to run ping tests on and that machine doesn't have anything like iCloud or drop box.

Im borrowing a firewall from work tonight to sit between my network and the router to see exactly what traffic is flowing.

Yes does sound like the classic case of upload congestion. No VDSL or UFB where you are?

No unfortunately. Not sure how it could be uploaded when I only had one machine plugged into that does't have any services installed that would be uploading.

I'm borrowing a firewall from work so will stick that in the middle and see whats going on.

Thanks for your help
