I have just replaced my faulty H500-T One Ultra Hub Modem with their new DN8245.

I am on Fibre capped at 300mb. I have a large complex system of multiple switches and access points, but until the upgrade everything worked well. (300mb down, 100mb up)

I just replaced the H500 with the new DN8245, the Wi-Fi speeds are fine as above, but computers connected via ethernet cable are all experiencing almost no upload speed (2mb Up only!)

I have rebooted everything multiple times from the ONT, Modem, Switches, Computers etc.

Any suggestions before I buy some USB Wi-Fi Dongles?

You mentioned you have a complex network here... Really you need to just test only to the router to determine if you've potentially got a faulty switch or something.

Yep. Unplug everything else, plus in one computer via a LAN cable to the new router, and test that first.

Still can't get this new One Router sorted.

300mb/s download speed on Windows 10 Computers, but only 1mb/s upload via wire ethernet.

Speed however is reasonable via WiFi.

One Teir 2 (Christchurch based) Help Desk have been unable to explain it.

They had Chorus rebuild my ONT profile and test the line speed to the ONT.

We have disconnected everything and just plugged the laptop directly into the Router & ONT, with same response!

Did you do a Hardware reset on the router? not just a power on off

Yes and One / Vodafone sent me another new Router and it was just as slow.

The old Ultra Hub is fine - 300 down, 100 up - but has other intermittent faults hence the replacement.

Their solution is to try and find me another old Ultra Hub that works....

Can you explain your setup? are they managed switches?

I have an ultra hub with a 24 port switch feeding the lan 1 input and another 24 port switch feeding lan 2. Then 2 decos, set in adhoc mode running from the ethernet ports in various rooms/ Working fine. On 300mbit plan also. No issues

Hi I have a similar system to you.

ONT to One Router (Ulta Hub then DN8245) into 16 port GB switch and 2 x Deco 20’s in other parts of the house.

Plus a few smaller switches and an Ac chess Point.

Disconnecting everything and just plugging Router into ONT and laptop direct into router gives 100 up on old Ultra Hub and just 1 at best on new DN…

If you disconnected EVERYTHING except ONT -> new dn router -> 1 ethernet cable to device. (including turn off the decos)

You should be able to login to it and Check the WAN/LAN status and see if its @ 1000mbit

Have you disabled the wifi? since you are using the decos?

Also make sure decos are in ADHOC mode

What switch are you using?

Thanks again for taking the time to reply.

I did unplug everything and connect the new Modem direct to the ONT, and then the Win10 laptop direct to the Modem.

This gave 1mb/s UP. I then switched back to the Ultra Hub and immediately got 100mb/s up!

I however did not power off the Deco units as they were no longer connected to the modem. - I guess I could try this!

I also was running the DN modem with its default factory settings (wifi enabled etc).

My Switch is a TP Link SG1016D.

I must stress that everything was working fine speed wise with the old One Ultra Hub, and the problem only arose when I changed to the DN8245 and was there with the second one they sent me.
Problem immediately disappeared when I reverted back to the Ultra hub again. (But the Hub has an unrelated issue that causes it drop internet access at times, hence One replaced it for me....)

The local One Tier 2 Tech Support Team are sending out a Noel Lemming mobile Tech on Tuesday to test the old Ultra Hub and two new DN's for themselves to confirm the ethernet speed issues.

I will let you know what they fine?

I have the idea that you are using the deco in router mode which is the problem you can't really have 2 routers running assigning ips. In that case you neeed to turn off DHCP in one of them. But the best solution don't run the decos in router mode (turn it off in their app)

You havnt tried what i said logging into the DN router and see what the lan wan conection is at.

You shouldnt be using the ultras or the DN for for wifi since you have the deco.

I changed the Deco's into AP mode but it made no difference.

The Noel Lemming Techs came today and confirmed that I had only 1mb UP on three Windows 10 computers (1 x HP & 2 x Dells) when connected to the new DN8245 Modem.

But get the full 100mb/s up when connected back to the old Ultra Hub.

They also connected their new laptop into my ethernet cable and get full speed in both directions.

So their assessment is that three of my computers are incompatible with the new DN8245 Modem and I need to upgrade them....

I think we need to start again

In terms of speed refer to here, so we are getting the correct info

https://www.speedtest.net

Heres my result same plan as you

Download Mbps 327.73

Upload Mbps 108.22

The HP'S and Dells you have, well it is possible that they only have 100mbit network controllers but i seriously doubt that. even if they are near 10 years old..

Are they running windows 7? 10?

RE: decos in A.P mode you can't run 2 routers on your network at the same time without reconfiguring at least 1 to have dhcp turned OFF as you will have 2 routers handing out device addresses. That is the other most likely issue.

Oh and I wouldn't trust the tech knowledge from Noel Leeming.

Edit: removed unnecessary insult, and fixed formatting.

All my computers are running Windows 10.

I have always suspected that there is some strange compatibility issue between the new DN8245 modem and the Ethernet cards / ports in three of my four computers.

The oldest Desktop, no name brand built from parts has 100 up & down via ethernet.

The three newer PC’s, (HP & Dell) have less than 1 MB/s up using Speed Test.

If I connect via wifi instead of cable the speed is better, but not optimum?

I might buy a TP Link PCIE network card tomorrow and try it in one of the suspect computers, only $25.00

I agree with your comments re NL, i was at work when they came unfortunately.

Be interesting to hear what the local Tier 2 One NZ Help Desk say. He mentioned trying to find me an old Ultra Hub to replace my original faulty unit.

Everything works fine with the Ultra and immediately bad with the DN!

Also I am aware of the DCHP / multi router issues, and have the Deco’s set up as AP’s with only one DCHP server.

Sounds like a Windows network card driver issue to me. Tried updating the drivers?

Can you post your actual result from speedtest.net? You keep refering to 1mbs upload, please give your download and upload mbits as reported at speedtest.net

Also can you check the following.

Go to the Playstore and make sure the deco app is current and updated.

In the Deco app click more, then click system , click update deco,

The Firmware of the main deco (assuming you are using the deco x20 from Vodafone) should report as 2.04 Build 20220216 Rel. 41671

Install any firmware update if there is one available. Also under your account setting, click about, that will show the app version mine is version 3.5.15.

I'm assuming that you have plugged the Decos into ethernet ports in the room locations. Do you have anything plugged into the ports on the decos themselves?

Now to the windows 10 pcs, are they full updated via Windows Update? check for Optional hardware driver updates. Reboot after everything has download / updated

Go to network status, from search box, click properties then scroll down, that will show the actual link speed which should read 1000/1000 (Mbps)

go in the search box and type network adapter it should come up with the trouble shooter "Find and fix problems with your network adapter" run it and see if it finds any issues.
