High Latency Spikes on ADSL

I've been experiencing choppy Internet for a long time now, sudden high latency and ridiculously slow speeds at seemingly random times throughout the day. Worse on weekends likely due to congestion.
Here are some tracert results from command prompt:

Tracing route to 8.8.8.8 over a maximum of 30 hops

1 <1 ms <1 ms <1 ms 192.168.0.1
2 2937 ms 3048 ms 2951 ms 172.18.217.1
3 3172 ms 2375 ms 1683 ms 172.18.74.57
4 54 ms 20 ms 23 ms 203.50.112.56
5 24 ms 27 ms 22 ms 203.50.6.190
6 50 ms 62 ms 48 ms 203.50.11.18
7 102 ms 57 ms 56 ms 203.50.11.91
8 69 ms 69 ms 69 ms 203.50.11.122
9 67 ms 86 ms 67 ms 203.50.11.173
10 72 ms 70 ms 71 ms 72.14.212.22
11 * * * Request timed out.
12 72 ms 74 ms 72 ms 108.170.233.194
13 71 ms 83 ms 70 ms 209.85.244.15
14 123 ms 84 ms 70 ms 8.8.8.8

Hops 2 and 3 have always been problem areas, as well as sometimes the 203 addresses. I'm no good at interpreting these results, so what are the 2nd and 3rd hops and what could be causing the high latency? 
Thanks.

Re: High Latency Spikes on ADSL

192.168.0.1 is gunna be your router, the next ip address is probably within the exchnage in your area. The high latency there looks like a line issue, however you cant really raise a fault for latency. But you can for drops and speed issues. Please post your modem stats so we can have a look and see whats going on:
On a Premium Home Network Gateway, T-Gateway, Gateway Max, or Gateway Max 2
(TG587, TG797, TG799, TG800):
http://10.0.0.138/ > Advanced > Broadband

On a Telstra Gateway
(Sagemcom F@st 5355):
http://10.0.0.138/ > Advanced > Gateway Settings > Device Info > General > xDSL (Bottom of Page)

On a Frontier Gateway or Smart Modem
(DJN2130 & DJA0230 ):
http://192.168.0.1/ > Advanced > Broadband

Default password is generally 'admin'
You're looking for line rates, power levels, attenuation etc

Are the tests being run over Ethernet or WiFi?
Are they being run during peak times (3PM-12AM)?

Are you using a VPN or proxy server?

 

Some gateways have a tracert command built in Advanced > Diagnostics > Connection.

If your gateway has this feature try a tracert from gateway

Re: High Latency Spikes on ADSL

Hey, thanks for the reply. I'm using a Netgear D6400 router, so I'm not really sure where to find this info.
These are the only vaguely related statistics I am able to find:
11.PNG22.PNG
The tests are being run over Ethernet, and at peak times, though the problem persists out of peak times (though is notably much less present outside of peak times).

Here are some speed test results. Maximum speed is usually around 1mbps. Used to be up to 9mbps on good days, 4mbps on average. As you can see, the speeds have been very inconsistent. One oddity I've noticed is often the upload speed will jump high when the download speed drops.

You're close, its just not showing the details we need. According to the manual should look like this.

You can also call the ADSL assurance team on 132200 and get them to run some line tests and raise a fault if need be. You can start a chat with the team here

Re: High Latency Spikes on ADSL

You're attenuation is ok, the noise margin isn't, 11-20 would be OK, anything higher would be better. Note: The longer your line the higher attenuation generally is and signal to noise ratio is lower. I'd recommend unplug your modem from the power point. Removed the adsl splitter and just have the netgear plugged in by itself, then plug the netgear back in and then give it 5 mins to reconnect. Then please re-post the line stats. If that doesn't make any change I'd recommend getting in touch with the ADSL assurance team as there may be an issue with your line.

Noise margin looks better. Id see how it goes fora day or 2 with out the splitter and if that's made it better you'll just need to replace the splitter
