New Full Fibre 1.6Gbps - Slow VPN Connections

[Fogzter]

Hi

I've just had my 1.6Gbps full fibre installed yesterday and without my VPN switched on I'm receiving the full 1.6 down and 115 up.  However when connecting  my Surfshark or Mullvad VPN using Wireguard protocal the speed drops to around 500Mbps.  I've tried deleting all my VPN connection on my Unifi router and recreating my key pairs etc as well I setting up different VPN servers but the speed is always the same.  I've also tried setting up OpenVPN, both TCP and UDP and these are even worse with speeds around 200Mpbs.

So my question is do EE perform some sort of throttling on VPN connections and is there a way around it?  If not then I'll need to cancel my contract as I'm still in my cooling off period and wondered if anyone has recomendations on whose services works best with VPN conntions?

Thanks

I've logged the issue with Ubiquiti, so I'll see what they recommend.  Cheers

@Fogzter You would have got an EE Smart Hub 7 Pro from them as you state the 1.6Gb/s package is in use. What does it show when you have it connected up to the ONT? All the Lan/Wan interfaces on that unit are 2.5Gb/s speed rated so you can connect it up and see?

When you were on the Airband FF900 package what speed were getting vpn wise, OR Policing parameter you are well over at the 500mb/s so do not think that would be an issue at all.

@Fogzter Can you follow and setup from the link below testing with and without you vpn in play. Also see what your MTU is set at by default on the unifi gateway.

Hi @JimM11 I think this may be a router limitation on the speeds it can handle.  Been looking into this all evenin g and I think that I may need to replace the router with one that can handle Wireguard VPN's at 1000Mbps and over like these 2:

or

As they both state they support 1,100 Mbps on WireGuard® and Max. 1,000 Mbps on OpenVPN-DCO. Whereas my Ubiquiti router doesn't state its max VPN speeds, but I'm starting to think it's probably around 500-600Mbps.  Just waiting for Ubiquiti support to get back to me about it.

@Fogzter Would not think so, that's a pretty good and up to date unifi gateway that you have, more than likely a wan setting issue of sort's. The wan interface on it is 10/2.5/1Gb/s but would expect it to sync at 2.5Gb/s on your new ONT from OR.

Was why i asked you to do the packet loss test, will hammer the upload connection real rapid and see if there is delay's etc.

Cloudflare is below if you prefer, that will give you up/down to inspect. All testing with Ethernet if possible wireless is just to iffy at present....

@JimM11 the WAN link to the router is indeed 2.5Gb:

below is the results from the tests:

VPN on:

VPN off:

Not sure what the MTU value is, but here is my WAN connection settings:

@Fogzter Will take a look when the posted pictures get approved for general viewing.👍

With the change Airband to EE, did you have to set the Unifi up as a PPPoE connection, no idea what your old ISP did connection wise.

[Fogzter]

@JimM11 Airband was PPPoE the same as EE, so just really had to change the username and password.

[JimM11]

@Fogzter Perfect should not be much in the way for the gateway to go off tilt so to speak.

Also @JimM11 I just dropped the VPN connection on the router and download the windows app and using that I'm getting 1139Mbps down and 105Mbps up while connected to the Wireguard VPN through the app, so it's looking more like a router issue?
