I'm using Sonicwall NSA 220 at work, for some reasons the speed on the LAN port (X0) is about 10m-15m slower than the WAN port (X1).
On the WAN port it's about 30M but the LAN port it's about 13M and this is very consistent speed.
Does anyone know what settings I need to check or change in the Sonicwall NSA 220?
any help would much appreciated.
download used to be about 13M and now it's 19M after the 5.9 firmware update. but upload is still the same, on the WAN it's about 11M but on the LAN it's about 4M.
