We also had OPTUS Cable and now you do not get a choice. You have to switch over to the NBN, they took our old cable 100/2MB/s and replaced it with 25/5MB/s for the same price. I’ve called them 4 times and they keep telling me they’ll switch it over.
So if I plugged into the older router via ethernet I’d get about 105MB/s down but always 1.5MB’s up
Now on NBN it’s supposed to be 25/5 and I was getting readings of 15/3MB’s so I’m terrified that they’ve done the same to us and will not admit it. They said it’s been switched to 100/40MB’s now and I’m getting an average of 21/9MB's
Something is seriously wrong and I’ve had a lot of different ISP’s over the years being a renter but OPTUS have been fantastic here for the last 6-7 years. Now they’re absolutely shocking. It’s such a shame, I get faster speeds on my mobile on 4G which is OPTUS too. How sad is that.
