Ookla says i`m <250mbps on my FF 900

Ookla says i`m <250mbps on my FF 900 .. Yet the TT speed test says I'm >900mbs ?

Been with TT for years and always found them to be really good but this is annoying ..

I was on GFast and got 250+ mbps which I was happy with but `coz TT is getting rid of "legacy products" they were going to hand me off to Utility Warehouse ..

I was not happy with being kicked off TT so looking at my BB offers to my home 900mbps was available if I was a NEW customer but no upgrades on my current acc 🙄

Anywho after many "chats" and phone calls I was finally setup with TT FF 900 😀

My BB speed is now less than Gfast I was on before !!

OOkla speed test creeps up to a poor 250 😑

According to TT speed test my router is connect @ 936 mbps👍 but my PC tests on various test sites gives me results similar to OOkla, I have always used ookla and trust their data ..

Any ideas why ?

The Ethernet I`m using is OLD so I`m hoping that is the cause ..

I cant login to the router for some reason as I wanted to see what it said about the connection but the login card details dont work ..

Does TT not want us loging into the router ?

I have asked on another thread what cat# ethernet I should get, the run is about 10mtrs ..

Any ideas and help MUCH appreciated ..

Thanks

Hi @KmogReborn , thanks for taking the time to post — and I’m really glad to hear you’ve been with us for so long. I know it’s frustrating when the speeds you’re seeing on devices don’t match the full fibre line speed, so let’s work through this with you.
From what you’ve described, the key thing is that the router is syncing at around 900Mbps, which means the full fibre line into your home is performing exactly as it should. When that’s the case, lower results on devices usually come down to internal factors, such as:

1. Ethernet Cable Type
If the cable is an older one (Cat5 or below), it will physically limit the speed to around 100–300Mbps.
For a 900Mbps service, you’ll want Cat6 or Cat6a for a 10‑metre run. That will ensure your device can actually use the full speed available.

2. Device / Network Card Limitations
Some older PCs, laptops, or network cards max out at around 250–300Mbps even over Ethernet.
If possible, check the network adapter specs or test with a newer device to compare results.

3. Router Login Issue
You should absolutely be able to log in to your router — we don’t block access.
The default details on the setup card should work, but if not:
Try a different browser
Ensure you’re connected directly to the router
If you want, @KeithFrench can check the router remotely from our side. Or you can contact our Full Fibre Team.

4. Speed Test Differences (TT Test vs. Ookla)
Our internal speed test measures the speed into the router directly, which removes variables like cabling and device hardware.
External tests such as Ookla measure the speed available to your device, so if anything in your setup is limiting the connection, Ookla will show that — and that’s likely why you’re seeing around 250Mbps there.

Re logging into the router it's worth noting there are 2 passwords there and sometimes customers have got them muddled up.

Also characters such as O and 0 are not clear.

I take a photo of them with my Phone and then zoom in for clarity.

Hope this helps.

Hi @Mandisa-TT @KmogReborn

Being just a customer myself, there is absolutely no way that I can log into your router at all.

Assuming that you have the Wi-Fi Hub 3, then in your browser, go to:-

192.168.1.1

Use the username of:-

admin

and the router password (not the wireless one, as pointed out by @fr8ys) quoted on the rear.

I will be happy to help with any part of this if you still require it.

@KmogReborn As we’re limited in what we can access and diagnose directly here on the Community forum, since you are a Full Fibre Customer if you’re still unable to log in to your router after trying the steps shared above (correct login details, checking the physical label, and trying another browser/device), the next best step is to speak with our Full Fibre Team.
They have the appropriate system access to check your Full Fibre setup in detail, including router authentication issues and any configuration points we can’t review from the forum side.
