Sophos XG Home 19.0.0 - bad WAN Upload speed

Hi,

I have two Hardware Appliances (an older one and a newer one) with 4 Intel i211 Network Interfaces.

I want to replace the older one against the newer one.

Both Appliances have the same config (Backup from same Backup-File), the same installation (from the same USB-Stick) and the same version.

Port 1 = LAN Interface

Port 2 = WLAN Interface (configured as VLAN only Port with two VLANs -> 11 and 99)

Port 3 = WAN Interface (PPoE)

VLAN 11 = Gäste WLAN

VLAN 99 = Internes WLAN

LAN to WAN: Download and Upload Speed from LAN Interface (Port 1) to WAN Interface is good.

My Problem which exists only on the newer Hardware Appliane:

WLAN to WAN: Download Speed form WLAN Interface (Port 2) is good, but Upload is very bad (only 9 Mbits instead of normally 70-80 Mbits).

On the older Appliance with the same config, same version, same installation I have no problem from WLAN to WAN (Upload Speed is 70 - 80 Mbits).

IPS is not activated

Both Appliances

Hi,

thanks for your reply.

The MTU on WAN with 1492 is correct.

As I mentioned all the config on both appliances is the same (including MTU Setting).

Hi,

Ok, which MTU Size do you mean? From my VLAN Interface or from WAN?

WAN MTU Size: 1492 (that is what the Provider expect)

VLAN MTU Size: 1500

Hi,

what is the AP type and what device are you using to test the speeds with?

Hi,

I am using

1x UAP-AC-Pro

1x UAP-NANO-HD

On both APs I have the same results (bad upload speed from WLAN to WAN).

I test the Internet Speed with different WLAN Devices (Apple iOS, Windows 10 & 11) and with different speedtests (speedtest.net, speedcheck.org ... ).

What does the management server show of the connection speed of the devices?

Hi,

the Access Points have a good experience and they are all attached with Gigabit connection.

The Clients have a very good connection as well.

I do not think, that it is a problem of unifi environment because I do not have any problems with my "older" hardware with sophos xg installed on it ... but possible is everything and I look forward for some more troubleshooting steps.

regards

Thorsten
