CL_Flush Entity Packet message !!!!!!

[old.Snake_Plisken[NFCY]]

Can anyone out there tell me a way of solving the problem that causes the above message to occur. I have been playing CS for some time with no problems and have had reasonably good ping and frame rate. But for about the last week every time i connect to a game i lock up after a few seconds and get this f***ing infuriating message. I have tried all the usual ping related tweaks "pushlatency" and "rate" etc. and have checked through my modem and network settings and they appear fine. Normal internet use is o.k. too.

HHHHHHEEEEEEEEEEEEEEEEEELLLLLLLLLLLPPPPPPPPPPPPP MMMMMEEEEEEEE PPPPPPPPLLLLLLLEEEEEEEEAAAAAAAAAASSSSSSSSE

The only thing I have heard that fixes it is setting your packet size to small (on your dial up adaptor). I did it to mine earlier this week and haven't had it since (but never had it that often anyway).
I am a bit sceptical as to whether it makes any difference because win98 is supposed to auto change packet size (or is it just MTU value?) on the fly.
