Ethernet and Modem

Problem is that the Internet connection is
usually broken after 5 to 10 minutes on the
new PC (ASUS Pentium 4.) Although we are
on a rural phone line, this does not happen
on the old PC (Pentium 2) which connects
well and stays connected.

The problem may be / System / Network
configuration. The old PC is set up with just
MS Dial-Up Adapter bound to TCP/IP. Both use Win98SE.

Having Win98SE, the new PC has this Adapter and
Protocol. It also has Ethernet circuitry main board
(Marvell Yukon Gigabit 10/100/1000) built into
the main board. If disabled, the ethernet tries
to reinstal itself on reboot and add itself to
/ System / Network confguration, which thus shows:
1. Logon
2. Dial-Up Adapter
3. Marvell Yukon Gigabit 10/100/1000 Dial Up Adapter
4. TCP/IP - Dial-Up Adapter
5. TCP/IP - Marvell Yukon Gigabit 10/100/1000 Dial Up Adapter

Case 1: With this default configuration for / System / Network,
the PC connects OK (using MS IE v.6) but loses the connection within
5 to 10 minutes. It never stays connected longer.

Case 2: With only MS DUA and TCP/IP the PC connects
only slowly (initially 500 bytes received instead of 25,000)
and loses the connection.

Case 3: With only Ethernet DUA and TCP/IP configured,
the PC cannot connect at all.

So Case 1 is the best currently available, but makes it
impossible to DL anything serious (e.g. AV data files
of 4 too 5 Mb.) But this does not happen on the old PC,
with no Ethernet, which connects with the simplest
/Network configuration and remains connected.
