After some advice on how to get a resolution to loss of internet speed in the rain . One question I had , what do people use for speed test , is answered in the sticky with vodafone speed test . I will try this next time , I have been using speed test net by Ookia .




For the last 6 months or so with reasonably heavy rain our broadband speed drops to an indicated , well lets just say an erratic 20 Mbps at best and devices start to not work . In reality this varies from about 6 to 18 and the ping is above 30 usually . One test I did resulted in 12 Mbps , but that seems to be due to a spike on the little graph on the speed test . The rest of the test would have been 3 or 4 at best . On a normal day we get aleast 48 and its steady with a ping around 15 , I realize this is above the average . I believe the issue is more its very erratic causing the continual hit and miss connection .




I called Vodafone to lodge an issue . The lady on the phone insisted we had a connection speed of 52Mbps when I was getting no more than 20 (had run more than 20 tests by now) and that with our distance from the exchange we should see no more than 22Mbps . I asked why I was only seeing 20 and was told it could be an issue with my computer , fair enough I can understand it could be , however without the rain I consistently get 48 to 52 and I am not in the habit of leaving my laptop out in the rain . Trying to explain I normally see her claimed 52 got me nowhere . She basically said her speed test was 52 and even if it was around the 20 that I said , it was still within acceptable limits . She said it must be a modem issue and wanted to remote into the modem to change settings , she was going to call back and do this but she never called . After a day or two it was back to its usual 48+Mbps . Until the next heavy rain and winter is coming .




So has anyone had a similar issue and how did you get it resolved , what was the issue ? I believe the cable to the house , or in the house , is getting wet but I am trying to keep an open mind . 


Does everyone get the speed vodafone say they get ? Any advice ? I cant get Chorus to look at the line until vodafone lodge an issue  .




The last time I had a problem with the line to the house it took me some time to get the internet provider ( I cant remember if it was voda then so assume not ) to lodge a fault with chorus . Lets just say I nearly used words I should not have when I said "would you like me to send you a picture of the two ends of the line the digger has just dug through" , this was after a 45 minute conversation on the issue might be the modem , it might be my computer despite me stating a digger has gone through the line several times etc etc etc  . Crazy system , some digger digs up the cable , not on my property and I have to log a fault with my phone provider before chorus will come out .




Sorry bit of a rant , any advise would be good .

Speedtest results mean very little. What happens to your xDSL sync rate during this period? Does this drop also?

"Attainable rate", "Sync Rate" and "Actual SpeedTest Performance" are three different things. Voda is probably telling you the "Attainable rate" which could be high but the actual sync rate may be low due to distance, wiring, interference/noise issues.


"SpeedTest" is Layer 3 performance test which has network overhead and is usually slower than actual "sync rate". As per above. Modem stats will be helpful to see what is going on.

Ok , googled sync rate etc and read a bit and have a better understanding of what is what , for a layman anyway . Logged into the modem and have these results currently .




SNR Margin (0.1 dB): 85 / 89


Attenuation (0.1 dB): 195 / 215


Output Power (0.1 dBm): 75 / 140


Attainable Rate (Kbps): 15640 / 59192


Rate (Kbps): 15706 / 52253




Not cable connected to the modem to do a speed test to bench mark it but I will do shortly .


Modem is a D-link DSL 2885A . I will have to have a look at these when its bad and see what it says , Does the atainable rate change ? Or is this accumilating the best connection rate ? If so if the line goes bad in the rain I should see a drop in the rate listed above ?

If your line is being affected by weather you should see the sync rate drop.

This. The next thing to do is when it rains and you see the symptoms, check the sync rates which you have just posted, and see if they have changed significantly.


In all likelihood they will have, and then it is a matter of working out where the water is getting in.
