Re: Super Hub 3 Slow In Modem Mode

In modem mode all four LAN ports are active - until you plug in your laptop then the other three become inactive (very much like radio buttons). The laptop will get its external IP address and connect to the internet, you don't need to do anything for Windows devices as by default they obtain an IP address automatically and obtain the DNS server address automatically. This is a good time to run a speedtest, BTW, as you've got a wired connection with WiFi disabled.

Re: Super Hub 3 Slow In Modem Mode

@Roger_Gooner - I tried this and it wouldn’t work (Windows 10 laptop, Ethernet connection, wireless disabled)

I might try another device(s) and see if I can make any progress with them instead.

Re: Super Hub 3 Slow In Modem Mode

@robe16 are you restarting the Hub (power off and on again) after connecting the laptop to the Hub? It has to be rebooted when a different device is attached to register the MAC address change and request a new IP address.

@jem101 - I wasn't aware of this, so no, I wasn't rebooting in between switching over from third party router to laptop. I will try this and see if I have any success. Thanks

In modem mode power off the hub for 2mins to allow a MAC change pre connected device.

In windows MS makes a mess of things by the DHCP going into Automatic Private IP Addressing and getting stuck so you have to unplug replug the Ethernet cable to force and DHCP Discover from 0.0.0.0 to 255.255.255.255 which you can see in Wireshark.

Re: Super Hub 3 Slow In Modem Mode

Many thanks all for your assistance so far, I have finally managed to connect the PC/laptop directly to the SH3 whilst it is in modem mode and run a speed test.

This is the moment where I now have to eat humble pie....

The speed was the full (circa.) 300-350meg that I would expect at this time on a Sunday afternoon. Therefore, I hate to admit it was something 'my side' of the network with my third party router.

Further investigation revealed it is the Media Prioritisation setting - I set this years ago when I was on a slower package and wanted to prioritise my streaming and gaming devices over mobile phones, etc. Appreantly turning this off preventing throttling that seemed to be taking place on all devices not on the list, thereby opening the full bandwidth and speed up for all devices to use.

So, I can now say I have resolved my issue and am happy with my service now!

(and yes, I've asked VM to withdraw my complaint and admitted it was my third party router after all - hopefully they'll be no hard feelings!!)

Re: Super Hub 3 Slow In Modem Mode

I have a netgear D7000 (ac1900) myself, and after much faffing got it to work with modem passthrough, sadly as other seem to report, it was losing about 100Mbs on ethernet for downloads vs the SH3 direct, oddly upload was near enough the same. Can anyone confirm a D7000 of getting close to passing through 390Mbs on ethernet connection with SH3.

Re: Super Hub 3 Slow In Modem Mode

Did you try cloning your laptops mac address to see if you got the same speeds.

 

Also which servers did you use can you try TNP and see if that is different to VM on speedtest.

I use a Draytek 2860 AC router, with my Hub 3 in Modem mode.

With everything set to the 'ideal' I get 380Mbps down / 35 Mbps up. ie full speed.

However I use QoS on the router (to prioritise my work connections over the kids). With this switched on the speeds reduce to 290Mbps down / 35 Mbps up, which is absolutely fine with me.

NB I don't use the Draytek's WiFi - if I switch that on I find the main speeds drop some more. I have a separate Archer C7 which I use solely as a wireless AP. It's located in the centre of the house  and doesn't choke the Draytek's resources.

Purely as a test is it worth you switching the WiFi off on the Nighthawk (with the hub 3 in Modem mode) and seeing if the speeds increase?
