Hi All,
I'm having problems with my D-Link DSL-200 USB ADSL modem on Win2000.
When I try to connect to the internet after a reboot, the connection
requires several attempts to connect.
As a minimum, it takes 2 or 3 attempts, but lately it takes several more
attempts, and yesterday it took 20 minutes = 80+ attempts to connect.
This connection problem does not appear to occur if I manually disconnect
and reconnect, but seems to only occur on reboot.
I can observe the modem status while the dial in is attempted, as supplied
by GSIcon.exe - which runs permanently in the taskbar, even when not
connected.
The modem state cycles between:
No Signal
Training
Data (with Transmit 160 & Receive 1920 being typical Values)
The important bit here is the modem reports a successful ADSL connection
(the 'Data' state) being made, and this happens even without attempting to
initiate the 'Network and Dialup Connection'.
When I click on the ADSL Icon in Network and Dialup Connections, the Dialup
status dialog displays:
Connecting to Telecom NZ ADSL
Dialing 0,100...
Verifying username and password...
Disconnected.
Error 619. The specified port is not connected.
Redial | Cancel | More Info
(Clicking More Info says 'Restart your computer to make sure all recent
configuration changes have taken effect.')
At the same type as the 'Disconnected' line occurs in the connection status
dialog, the modem status cycles back to 'No Signal', and then begins to
'train' again.
On the rare successful connections, I get the following instead of the
'Disconnected' & following lines above:
Registering your computer on the network.
Authenticated.
... and then the status window minimizes to the systray.
My question is: Who is at fault here? Is it my ISP or do I have a faulty
modem, a misconfiguration of my software or a faulty delivery of ADSL to my
location?
My ISP Helpdesk have suggested I have a faulty modem.
My modem details:
http://www.dlink.com.au/products/broadband/dsl200/
D-Link DSL-200 ADSL USB Modem
Driver release 1.10.00008Q (Wan USB)
Firmware Release N55.1
Control Panel Version 3.1.1
Modulation G.DMT (as per my ISP specficiations
http://xtra.co.nz/help/0,,5739-907829,00.html#modset . I have also tried
Multimode to no effect).
The D-Link helpdesk says that as long as the modem gets to the 'Data' state,
that means that the modem is doing its job fine, and no warranty claim will
be honored.
My OS is Windows 2000 SP4 (the problem also occurred under SP3). The drivers
for the modem are the latest available, and the modem reports no errors in
device manager. When the connection is established, no other
problems are observed.
The ISP & ADSL provider's (they are one and the same) technician came and
tested my ADSL implementation with a
Nokia M1122 Ethernet modem. He reported the following stats:
Bit rate:
Near End 6304 kilobits
Far end 896 kilobits
Noise Margin 10dbs
Attenuation 32
which is quite good for the region.
Of note, my connection speed using the USB modem (when successfully
connected) is only around 1900/160 kilobits. Does this possibly indicate a
fault in the modem?
Overall I suspect this is an ISP problem, as the problem is occurring at
the 'Verifying Username' step and the modem is in 'Data' status, with the
modem sending and receiving data fine.
Questions I have been asked by the ISP Support Desk.
Q. Have I rebooted?
A. Yes many types. This problem has recurred over several months. In fact,
it only occurs when I reboot!
Q. Have swapped USB ports around?
A. Yes. I also have a USB printer which works fine, and I swapped over the
cables with that, to no effect.
Q. Who did the installation?
A. The ISP/telco's own installer. It was a full install (i.e. no phone
filters
used).
Q. Can I use the phone line?
A. Yes. The problem recurs whether or not the phone line is in use.
I have scoured google groups history for help, and one poster suggested
toggling 'Negotiate multi-link for single link connections' under
Network and Dial-up Connnections
ADSL Icon Properties
Networking Tab
PPP Settings
Negotiate multi-link for single link connections
The problem recurs with this check box checked or not.
Any pointers anyone? I could try another modem, but they're expensive so
I'd like to try other options first.
Thanks in advance
