Hi, 
I have an interesting case which I can't seem to work out. Every day at the same time the internet will start going pretty slow, streams will start buffering and shortly after the router will lose its ADSL sync. It'll reconnect in about 2 mins then following that the internet will be as usual again. On ADSL2+ with DSL-N55U as modem-router.

Router log just shows as:
Aug 16 22:59:53 WAN Connection: Ethernet link down.
Aug 16 22:59:53 stop_nat_rules: apply the redirect_rules!
Aug 16 23:01:02 pppd[340]: Connected to 00:aa:bb:01:23:45 via interface eth2.1.1
Aug 16 23:01:15 rc_service: ip-up 481:notify_rc stop_upnp
Aug 16 23:01:15 rc_service: ip-up 481:notify_rc start_upnp
Aug 16 23:02:12 WAN Connection: WAN was restored.

Router has been updated in firmware but still same issue. It's been doing it for quite a few months but it is somewhat inconsistent, sometimes it will stop doing it for a few days and sometimes it will change the time it disconnects each day.

Any suggestions?

- Your ISP and plan
Slingshot, unlimited
- Type of connection (ADSL, ADSL2, VDSL)
ADSL2+

Do what this says, the robot missed you for some reason.

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?

It will probably be an alarm system on the line if its the same time everyday. You may not have it configured to be monitored but it still will be trying.

This. A master filter installed at the demarc with the alarm on the voice side will avoid this issue.

There's no alarm system that I know of? Cable comes in window then goes into a inline filter with one end going into phone and other into modem router.

In the window? Really? There should be a demarc point of some description between the Chorus network and the internal building wiring - do you know where this is?

Well not quite just in the window. There is a demarc point outside and the cable from there comes in the window (to a wall jack not on the wall) then into ADSL inline filter into router/phone. I was more meaning that there is no alarm system I know of.

Ah, that makes more sense! If there's no alarm, is there any other pattern to the disconects? When someone uses the phone, or some other appliance? Check the jackpoint you have for any signs of corrosion as well.

No other cables into the point of entry box that could go into the rest of the house to an old alarm system that noone knows about?

Only pattern is the time really. Always the same behavior that the connection will slow down, then disconnect briefly. The disconnect will still happen regardless of the load on the network/phone calls etc.

Fairly sure that it is just the single cable coming in the window and we have never had an alarm system in the house. 

I've put a +5db stability adjustment on it in the past but it made no difference from memory.

i doubt the wiring would have been through the window since the house was built. might pay to get up there and take the cover off and check if there is any other wiring there

The room the cable/router/phone is currently in was rebuilt some years ago and the jack has never got around to being properly put on the wall.

You never said what time it happens?

but ive seen something similar with a dodgy power supply unit/circuit being effected by ripple control signals (for hot water and night storge control) by not supressing the noise into the Modem/router

Try changing the time (don't use NTP) in the modem - that should rule it out as being something to do with timing in the modem itself. Not very likely, but worth ruling out.

It doesn't have a RTC so all I can do is change the time zone it syncs for.
