server stops responding

[Frank B. <fb...@sy...>]

I installed VNC1.2.9 server on a WinXP-home system to help provide remote 
support at a friend's house.  Since there is no cable/dsl close enough to 
reach their rural residence, they use a wireless ISP, but use wires inside 
the house.  ISP provides a static ip, so connecting to VNC server is not a 
problem; desktop does appear normally.  But after a few seconds (perhaps up 
to one minute), I get no more screen updates from the remote 
system.  Remote system is still working; because I can disconnect and 
reconnect anytime; but it still stops working after a period of time too 
short to get anything useful done on the remote system.

I run 1.2.9 client on Win98 with /8-bit option; my dsl connection is rated 
at 1.0 megabit, but we only get about 0.75 throughput on a good day.  I'm 
not sure what the bandwidth for the wireless ISP is, but it's not great - 
rather slow actually; but I thought VNC should work anyway.

Any ideas why this is happening and what I can do to fix it?
