Hello I have a issue about transfer data by local lan between pc and nas, behind my new Zyxel usg 40w. Before I used another firewall (free) and the transfer was more than 100 MB/s now's about 35/38 MB/s. ? Already I tried to change in session control the session limit by 0 (unlimited) but nothing! Please let me know what else I can do it thank you ! -

    PC connect with USG's wifi?

    If so, the performance may effect by different distance. The enabled UTM service also will effect speed.

    Hello Jeremylin thank you for you reply but the pc is connected by cable to the switch (all port are 1 GB) and NAS as well. So It's normal max speed 35/38 MB without UTM service ?

    With UTM the speed is decreased...25 MB.

    With lab test result, the download/upload of USG40W with HTTP are 67MB/62MB

    Can you private message the configuration for check further?
