Thus not the [advertised theoretical values] of your ISP. Measure your real speed on the DSL router itself without all the equipment attached.

Do you also want to use something like Mumble to talk with your buddies?

peet wrote:QUOTE (peet @ Sep 18 2014, 02:32 PM) Was the reserved minimum uplink / downlink for FreeAlleg + mumble together something like 98/98 KBytes/sec?

@Dusan. It is my experience that smaller MTU / MSSI's are often better processed by some ISP's, on an OpenVPN stream for example. I seem to have good experience with 1200.
