modem drops - pls help

It's an HP running XP home edition.  In the last few days, the modem has started dropping carrier for no reason that I can figure out, but may be related to traffic (i.e. it only drops when I'm downloading something like a web page or email, not when I'm just sitting there reading a page or mail).  I've tried removing the drivers & letting the wizard reinstall them, but to no avail.  Of course it could be hardware, but since the PC is only about 6 months old, is there anything in the configuration or registry that I should look for?

Thanks one & all,

Ken

a few questions in order to get a better idea of what hardware you're dealing with here.

1. what is the exact name of the modem listed in the modem control panel
2. (while offline) do a diagnostic on the modem and get the ATI3 response and post that in your followup response
3. what are your connection speeds...have they decreased or increased since this problem has started?
4. How long is your phone line to the modem? Is it going directly from the walljack to the modem or thru a surge protector or splitter?
5. What product line & model # computer from HP is this?
6. Have you made any changes to the phone system at your location recently? (adding a phone, moving phones, moving the computer to a different jack)
7. Are you dialing the same access number you were before or are you dialing a different one? Also have you tried using alternate access numbers for your ISP?

Have you added any initiation strings??
The 7 questions i asked are designed to figure out what init string to be used if any is needed.... hopefully we'll find out those answers soon.
try:
start->control panel
then go to either phone and modem opt. or printers and other hardware.  (if you have printers and other hardware, you will have phone and modem opt in here)  then click the modem tab, and go to properties.  I am assuming that you have a Conexant modem, so click on the advanced tab in prop.  In here, you have extra initizilation(sp) commands.  Enter AT+MS=V90.  Also, check your driver date and update.
Note:
I am making the assumption on the modem due to HPs perpensity for Conexant modems in recent times.
Let me know if this works.

Sorry about the delay in responding, had the flu.

The hardware wizard identifies the modem as a "Lucent Win Modem" on Com3.  Connection speed is 21.6 kpbs, that's about normal for here in the sticks.  Phone jack length is unchanged (about 3') since before the problem occured. The model is an HP pavilion 521n.  Nope, no phone changes to jacks or wiring.  However, to resolve another problem HP tech suppt had me run the following:
regsvr32 Shdocvw.dll
regsvr32 Shell32.dll
regsvr32 Oleaut32.dll
regsvr32 Actxprxy.dll
regsvr32 Mshtml.dll
regsvr32 Urlmon.dll
Still using the same number to call the ISP, not sure another is available (I'm using a cheap service Neandertech).  I'm assuming since this isn't (?) a conexant modem, I shouldn't add the above to the modem string?

Does this help?  Thanks one & all...

here's a little more...

The dialup and handshaking work just fine.  That is, it unfailingly calls and successfully passes username & password.  The problem is that 30 seconds to 5 minutes into the connection (usually while downloading my mail or loading a new page), the phone call drops.  Could this be a packet size issue?  Noise causing too many retries?
which email program? If Outlook Express...there is an option to hang up after sending or receiving.....also check the Internet Options to see if the boxes are checked that say "Disconnect if idle for 'X' minutes" or the one that says "Disconnect when connection may no longer be needed"...(for OE TOOL=>OPTIONS=>CONNECTION TAB  and for IE its TOOLS=>INTERNET OPTIONS=>CONNECTION TAB=>SETTINGS=>ADVANCED BUTTON)
For a Lucent Win Modem try this string: AT&FX
Outlook 2000.  It's set for 20 minutes of idle time before disconnect.  I'll check the modem string as soon as I leave this.  Thanx...

Thanks for your persistence.  Downloading the latest drivers for the modem helped too.
Right On!!! Glad you got it going!
