Hi @melsayed34,


Welcome to TPG Community!


We've checked the test that you've provided and it requires further investigation.


We've escalated this case with our Engineering team and they'll be in touch with your within 24 to 48 hours via SMS or phone call on the number that we have on file.


Should you require further assistance, please let us know.


Kind regards,


Level 2

Thanks @BasilDV it was really frustrating trying to call up customer support about this, appreciate the help.

I'm still experiencing the same problem, tried different computers. the problem is with the TPG network. I'm opening an official complaint with TIO

mo@Mohameds-MBP:~$ ssh -T
packet_write_wait: Connection to port 22: Broken pipe





Hi @melsayed34,


We've seen that this has been previously escalated to our Engineering Team and you have been in contact with one of our Engineers found no fault on our our network. The service has been connected for 3weeks 1d 9m.


We are providing/responsible for the path and destination but not the access of any specific website since this is a NBN Residential comes with Dynamic IP address. We've seen that our Engineers recommended to refresh or turn on/off the modem/router.


Let us know how it will go.

Hi Shane,
Do you really think I would go to this length and open a case with TIO for an issue that could be solved by restarting my equipment ?!
I can forgive most things but not insulting my intelligence really. Anyways the issue is yours and I’m gonna go all the way to prove it. I’m only willing to let it slide if you terminate my contract so that I could use another provider. I know you guys don’t have enough motivation to really track down this issue which is what I’m going to give you by opening this complaint with TIO.
So I’m gonna wait for a call from you guys.


Hi @melsayed34,


We apologise if you feel that way. We will treat this as a complain and raise this to one of our Complaints Resolution Case Manager. We'll request for urgent case investigation on this case and you will be contacted via email or phone call once the assessment is done.


Let us know should you require further assistance.

Hi OP, Shane and others:


I'm still having the same issue in all of my computers (TPG - NBN Melbourne Area). The problem is related with the IPQoS and thethroughput. I found a solution that I will like to share with you (and help you with this frustration, I've been there):


In your ssh/config file, you have to add this line "IPQoS lowdelay throughput":



cat /etc/ssh/ssh_config
Host *
StrictHostKeyChecking yes
IPQoS lowdelay throughput


Then you need to restart your ssh service and it should work!


Hope it helps!



P.D: Sharn, it would be really nice if your team can fix this issue because it's pretty annoying to have to modify all my ssh config with that configuration.




Level 2



I am having the same issue. My ssh connections are not stable whenever I am connected to TPG. It started having the issue after TPG made the changes to the superfast. (dont get me wrong I do enjoy superfast nbn)


My ssh connection is really unstable and unusable without having IPQoS setting in my ssh config. Can you fix it up at your end, please?


Before you ask me to perform any other tasks.. 

I have done the following.

- connect laptop to the router by wire

- restarted router, restarted modem

Any update on the matter?
