Internet Speed Reduced By 50%

A week ago my internet speed was 17000 - 21000 kbps (I live in Australia...) then BAM, internet speed drops to 8900 kbps. I used ozspeedtest.net (as well as many others) to check my speed.

Here are the actions I have done to fix my internet:
- Turned off router. Left it off for 10 minutes. Turned back on. Took about an hour for the router to reconnect. No change in internet speed.

- Called Internet Service Provider (ISP) and talked to some guy called Greg with an accent thicker than molasses. Did a line test on my router. Results were that there were significant line drop outs. They gave me a priority line (or something like that) in order to fix the drop outs. Did not change a thing.

- Tested router and internet speed on my laptop. Internet speed was 20000 Mbps and my download speed was 1.8 MBps (normal levels). Still took about 20 minutes to connect to the internet though.

- Called ISP back and told them. They said that since my speed on another computer was normal they couldn't do anything to help me. Classic ISP.

- Here I am talking to a fleet of computer technicians and hopefully, after pooling your collective knowledge, you can help me get my stupid computer back in line.


Thanks for any support you can lend.


APPENDIX: Here is what happens when my router struggles to connect to the internet:
- On light = green
- Ethernet light = green
- ADSL light = flashing green then solid
- Internet light = red then after 20 seconds or so it will turn off.
- ADSL light = turns off. Then begins to flash green and then turns solid again.
- Internet light = red then after 20 seconds or so it will turn off.

This process continues for about an hour or so (less on my laptop).
 
Solution
The ADSL link is entirely between your modem and the ISP, and clearly there's a problem there.

As for taking less time when having it connected to your laptop I could only say it was a coincidence, download speeds are being sustained by the "priority line" they "gave" you, basically they raised the SNR (Signal to Noise Ratio) margin to compensate the drops in the line to your house, those drops shouldn't be happening at all, and a higher SNR will usually produce a higher latency with the possibility to cause corrupted downloads.
ADSL link taking that long to setup it's either a failing modem, failure in the cabling from the CPE to your house (most likely this one) or problems at the ISP concentrator router (if so other ppl with the same service should be having the same issue).

So....... no matter which of the three is the issue, is your ISP responsability to fix it, insist on the fact that the modem is taking much much longer than it should to get the ADSL link up (shouldn't take more than 1 minute).

Sorry also should have mentioned that I have tried another router on my computer and it was the same thing. Took a long time to connect to the internet but nowhere near as long as my desktop did.

But how can it be the fault of the ISP if I have tried both my routers on my laptop and the speed has been normal (albeit with a long connection time)?

Wow... I know some of the words you just wrote. Some.
I think we need to backtrack some. They main concern is the speed. I want my speed back. I don't like this speed. It's not nice enough for what I'm paying.

If my speed is find on another computer, how can it be the ISP's fault?
 
well if you see that it is a consistent issue on the PC, no matter the hour you try, then use a bandwidth monitor software on your pc, assuming the ISP service is working well, then there must be something using/reserving the connection on your pc.

You could try with NetLimiter 3 Pro, or Capsa network analyzer.
