Hi im on a NBN 50plan with a FTTN connection: this morning i had to restart my modem to get my internet connection working again. I logged into my modem and noticed my maximum downstream line rate has dropped from roughly 55000 kbit/s to now only 40065 kbit/s 

Im on a nbn 50 plan and have always been able to reach almost the maximum speed. Modem is connected directly to the wall and is the only connection coming in from the street. 

I conducuted a speed test today using your speed test tool with my modem connected directly to my computer and have noticed the loss of 10-15 Mbps.


Any help on outages or if my connection needs resetting would be greatly appreciated. 


Thanks in advance.

Hi @BasilDV thanks to the tech team calling through. A reset did not make the line speed better, while it is within the acceptable range it's disappointing that it has dropped so much. I will try to see if I still have a screenshot of the line sync data from when I first moved in. I think I might purchase a new modem after Christmas to see if it gets better.
Do you guys have a list of FTTN recommended modems at all?

Ok so the file attached in this message is a screen grab of my modem sync from when I moved in in 2017 around the month of May. The downstream line rate was only 28101 kbit/s as I was on a 25 Mbit plan at the time but you can see that the maximum downstream rate (sync speed with node) is 54779 kbit/s and maximum upstream rate is 21599 kbit/s
The second photo taken this morning after speaking with tech support on the phone last night and resetting the modem shows the maximum downstream line rate at 39878 kbit/s and maximum upstream rate at 9329 kbit/s which is significantly lower. 

Can you please review the images as a point of reference please?
