Up/Down: the direction of the stream ("Up" means client->server). > 713312/878371 0% 15.795369ms=B110.066666ms The first number is the bitrate, the second is the maximum bitrate within which Gal=E8ne is trying to fit (estimated by congestion control). 0% is the estimated packet loss rate. The last figure is the RTT and the estimated jitter (for down streams only). > Especially, what are the 37% ? You're referring to this stream: > Down 969a21a58e75227f0cb06a84924815e9 24503 > 30488/9600 37% 59.869669ms=B14.625ms > 299800/14903 0% 61.573201ms=B15.477777ms The user is having 37% packet loss rate, which is extremely high. The congestion control algorithm has dropped this users rate to 24503 bps (9600 for audio, 14903 for video), which is way lower than Gal=E8ne can possibly achieve. Either the user is behind a very slow link, or they're behind a WiFi link with extremely high loss rates. If the former, they should disable the video feed (Receive->Nothing). If the latter, which is more probable, they should move around until reception is better (there's probably a couple of carrier walls between them and the router). -- Juliusz
