I installed UTM 9.2 and had no problems with it so far. BIOS Version is still F1, USB 3.0 and UEFI BIOS are enabled.
In a few weeks, I'll start configuration and then I can report performance values regarding the J1900 and the realtek NIC. But first I have to read about configuration of the UTM, when I get time for this.

Here is the short report. So far almost everything is working.
Just a few problems aren't solved. The Sophos UTM is connected to a Fritz!Box Cable Modem with a 52 Mbit/s connection. DHCP is just active on the Sophos UTM. Eth0 (internal) and Eth1 (external) have different IP-Ranges (eth0 192.168.2.x; eth1 192.168.178.x).
The Cable Modem is wired to the Sophos UTM, from which one cable is connected to a WLAN router. Switch 1 is wired to the WLAN router, switch 2 with switch 1.
Download rate at some PCs connected to the local network isn't that good. With some PCs I get constant full speed (6.5 Mb/s), other ones are limited for example to 3.7 Mb/s.
Highest amount of CPU usage was about 32 %. If any download process is active, CPU load is about 20 - 25 %. Therefore I don't think it is a problem regarding the J1900 or the Realtek NICs. Websites are loaded very quickly.
That's strange, I've done some tests. Download speed with a HP Server (HP 330i NICs -> Broadcom chip) is absolutly constant at full speed, no drops while downloading a file with > 1 Gb. When I start the same download from my PC (Realtek NIC, Win 7 x64), which is also conntected by wire to the local network, I get only 3.7 Mb/s.
If I use a tool instead of the browser to download, I get full speed. Does anyone know what's the problem?
The result is the same, whether I use Firefox or Internet Explorer. Updating NIC driver didn't help either.
