The speed profile issue, looks to be related to an incorrect profile being applied to your account by Zen. I don’t think it’s end user equipment related. Again best following that up with Zen directly to resolve.


I rebooted the ONT between the first and the second test, which must explain the change in Ping speed. I'll try rebooting it again later.

Thanks trillium, I will do so and see what they say. Though the service was advertised as having these upload speeds...

The tech support guy said the following:

"We used to offer symmetrical speeds but now via city fibre we are only able to get limited amount of the upload speed and I believe our networks team have amended profiles for the upload because customers were not getting those upload speeds."

So it looks like we're asymmetrical for the time being at least.

Hi, our CityFibre connections are advertised as asymmetric for the reasons mentioned earlier in this thread. But are in fact delivered as a symmetric service.

If you think an incorrect profile may have been applied to your connection feel free to drop me a private message and I'll look into it for you.

Thank you ajays, I will send you a private message.

Just to say publicly, ajays was able to sort my issue. Gone from 125mbps hard limit upload to over 900mbps on our gigabit connection. Yet to check the 300/50 connection as I'm at work, but I'm confident he'll have sorted that too.

So others were correct, there seems to be no need for the connection not to be symmetrical.

Many thanks to him.
