Solved! s...l...o...w... ppp xfers
This did it! Talk about counter-intuitive... transfers going too slow? DECREASE your modem port speed!!! Thanks to everyone, - Rick what have you set the modem port speed for pppd to? I had mine at 115200 (the default) but had exactly this problem at that speed. I have since dropped it back to 38400 and throughtput once again becomes fast and sustainable. -- loki
RE: s...l...o...w... ppp xfers
I'm looking for some troubleshooting help. Slink is working like a champ in all aspects but ppp connection speed. Actually, I connect at high speeds, but my sustained throughput runs from only 200-400 bps! When first downloading, I get a burst of speed, but in seconds all activity seems to stop then another short transfer burst... then another pause... etc. (I am using an external modem that works fine in windoze98). Am I looking at a buffer overflow or handshake problem? What should I do to help diagnose this? Thanks! Me, again... this is still unsolved. I've tried the two solutions offered: 1. echo 0 /proc/sys/net/ipv4/tcp_timestamps 2. try turning off all compression by ppp Neither one helped (though by turning off compression my throughput MAY have gone up to 500-600 bps.) I've attached my ppp.log and debug.log for any kind sole that wants to dive in! :-) - Rick
