Re: Booting PC disconnects ADSL Modem

Part of a long list of reasons for a dropped ADSL include ground
loops created by building AC electric. Assumed: you know all machines
have proper safety ground connections (so as to eliminate floating or
ground loop problems).

Wiring in the house is fine. In fact, it's all new. We're doing up an old house.
The problem existed before we started the wiring upgrade.

Also, I had the wife's computer connected to the network via a 108mbps Netgear
wireless network. Did it then. Then later on, after we wired in the LAN, I
connected her PC to one of the 4 ports on the Netgear wireless router. One of
its other ports was connected back to the modem as at the time I didn't have
enough spare ports wired in.

Then, when I finished upgrading the wired network in the home, her PC was
connected directly into the ADSL modem via one of its ethernet ports. The
problem still remains.

So, have tried different wiring setups, both for power and ethernet. Made no
difference. Have checked software configs, virus scans, hardware configs in
BIOS, etc.. Nothing out of the ordinary.

Both her PC and mine run Asus P5 motherboards with identical NIC chipsets and
configuration.

And the problem occurs AFTER Windows starts loading and BEFORE things like
network connections and logins are established. Unless of course, all this stuff
happens during the first two or three seconds of the "Loading Windows" splash
screen period.

Time of the event (as Windows loads drivers into NIC) implies
grounds are not a problem. I can only assume all are 100 Mhz Ethernet

Presumably you mean 100mbits, mot Mhz?

break that unknown into parts to solve it. Find the NIC
manufacturer's diagnostic for that Ethernet chip. This diagnostic
will load and execute without Windows. Now what happens to the ADSL
connection when NIC diagnostic loads and executes?

This was a painful exercise. The internet to Asus' website is awfully slow, and
it's not the most friendly site to navigate.

And no, I found nothing like what you describe. And how does it load without
Windows? Do you install it onto a boot floppy or something?

Hey, if you can find what you're describing for an Asus P5 DG1 Pro with a
Marvell/Yukon NIC, then I'd appreciate it. I can find drivers, Asus Update
Utility, but that's about it.

Setup the Ethernet post as disabled (from Control Panel, Device
Manager, or Network Connections). Then reboot the machine. Does this
eliminate ADSL interference?

Good one. Didn't think of doing that.

Now, if I discover that when Ethernet Networking is disabled, what then?

Remember, this process wasn't enabled when the Netgear wireless card was
installed in the PC (and yes, I've uninstalled it and ensureed that all drivers
have been removed).
