ADSL Connection

Hi

I am connecting to the internet through an adsl modem connection on an XP(sp2) machine. Some times it does happen that the connection is lost, usually because of an fault on my side, like modem cable being unplugged.

XP is however set to redail when a connection is lost and thus i would expect it to be able to make an connection again if I plug the modem/telephone cable back in. This does not work though, even if I stop the automatic redail and try to do it manually it does not work. I even tried logging of xp session and the logging back on and then try to reconnect, but still no luck.

If  i click connect it just says " Connecting through WAN MINIport adapter (PPPOE)" and that is it. I also have ICS running on the connection.

The only way around this problem currently for me is to delete the connection in "Network Connections" and then to recreate it. After doing that I am always able to connect again to the internet with the adsl modem.

Any suggestions, help, whatever, will be appreciated.

Regards,

Pieter

Sounds a bit odd to me... Normally you don't "dial" in to an ADSL connection. You hook up the modem to the ADSL connector on the line splitter (the filter that separates true 'phone from the ADSL signal) and then you power on the modem. Once its lights show that it has a proper connection, you start up or restart your PC and that's about it. Some ISP's require that you go to a specific login web page to get proper internet access. What does your ISP documentation say about restoring the connection?

rid: guess Pieter is in Europe, where authentication usually is required by dialing in on ADSL, too.

Pieter: I found cfos (www.cfos.com) to be a useful driver, which could alleviates your pain. Unfortunately it is rather expensive, but worth the money - you might like to try it out for 45 days free.

" Once its lights show that it has a proper connection, you start up or restart your PC "

sorry Rid, but not always true, personnaly I'm using a starbridge modem/router and if I loose my connection (bad provider, happens at least once  a day) I just power down the modem, bring it on again and once "the light" shows a connection it only takes a second or two before my laptop/pc/kid's pc establish a connection again, without rebooting or waiting for the light before starting them up.

Hi Pieter,
  I worked for an ISP helpdesk offering ADSL connections here in NZ. Many things here are quite similar to Europe.
   Let me start by explaining that ADSL modems can be internal or external. An internal ADSL modem works much like a dialup except that the dialer cant be configured directly through your OS in most cases & is suplied by your modem manufacturer to ring a dummy phone number. The second is an external ADSL router. Most external ADSL modems today fall in the router or switch category depending upon the money you spend.
  Troubleshooting them is very different. Ideally, restarting your PC resolves problems for internal ADSL modems since pulling the cable alone doesnt register a full disconnection from the ASAM/DSLAM instantly & the port might still be allocated, so redialing may not work. With external routers, the device behaves independantly as its refreshed a set number of times, usually 1 in every 10 secs to report to the ISP its active connection status.
  With internal modems & dynamic IPs that most ISPs provide, your XP SP2 or other firewall may block your dialing. Also check that Antiviruses are disabled just for troubleshooting.
  So basically, if you disconnect intermittently, restarting your PC is a great help even if you have external routers. Even with externals, simply putting the plug back in may not always help & powering down may be needed to re-authenticate on the network.

Cheers,
Zubin

"sorry Rid, but not always true, ..."
I don't claim it is always true... it obviously depends on the provider and their way of doing things. Some author feedback would be nice here.

you said you have a PPPoE... (do you connect to it with standard LAN cable?)
usually you can access your modem config via http...
what is your modem?
i think if you tell us its name we can help better...

if the signal goes out can be an ISP issue.. but if when you reinstal the driver it work.....

in some PPPoE (and some PPPoA) usually you can light on the modem without the computer and you can see by a led if there is the signal

if this is your case.... the signal go away from the modem or from your computer? i mean... there is not connection but the led is lighted or neither of this?

Wow!

Thanx everyone fot all the replies, really appreciate it.

A bit more info:  Yes I am in europe, united kingdom to be specific. The modem is external, connected by USB. Router? I don't know to be honest.

All I do is plug the phone line into it, after plugging it in to the adsl filter. The modem then connects to the the pc by USB,(would you normally connect a router via usb?) After installation of the driver software that comes with the modem there is a utility in the system tray that monitors the adsl connection. If the cable is plugged in, it indicates that an adsl(broadband) connection has been made. There after I create connection to the ISP with the create new connection wizard,(connect to the internet, setup connection manually, connect using a broadband connecton that requires a user name ect.,)  in which i have to supply a username and password as provided by the isp. Only then can I connect to the internet by selecting the connection that i just made and clicking connect.

If I by then go and unplug the telephone cable, the icon in the system tray that represents the driver, indicates that there is no longer an adsl connecton. Needless to say at this piont windows is already trying to automatically reconnect. If i then go and plug the telephone cable back in, the driver indicates ,after a few seconds, that a adsl connection has been made, again. So I would recon that after that the automatic reconnect(which is still valiantly trying to reconnect) will actually succeed at this point. This does not happen. The same is indicated on the modem, no telephone cable - only power led is on, telephone cable plugged in - connection light flashes a few times and then comes on indicating a connection and led indicating data being send or recieved flashes once in a while.

Even if I cancel it then at this piont, sometimes there is 3 different ones trying to reconnect to the same connection, and then trying to do it manually, it does not work. Unplugging the USB cable, which is the same as "powering down" the modem, and plugging it back in, does not work either. I think I have tried restarting the pc, but can't remember if that did the trick, believe it did though, but i would like to have a better sollution.

I am using sp2 firewall and AVG anti-virus(the free one) and will try dissabling them to see if it has any effect on the situation, however why was i then able to connect in the first place. I remeber with 98 or 95, if you had a problem like this i would use the task manager and close all apps listed in it relating to connecting to the internet(dail-up networking, iexplorer ect,) since they basically had ports open to the modem and redailing will not work until those are closed by closing the apps. I don't however know howto do the same in xp.

The modem is a BT AOL generic thing that comes with signing up with AOL or BT. I am however using it to connect to a 3rd party ISP (virgin). The actual make of the modem, chipset is global something, will have to check when i get home.

I really hope all this paints a clearer picture, and i will also be increasing the pionts since I have loads of them anyway. I will only be able to test any theories when I get home tonight. And my deepest appologies for giving such a long winded comment...

Thanks

Pieter

it can be
1) not your issue... it's the provider (ISP) BUT if reinstalling fix... you can exclude this (how about rebooting?)

2)
USB adsl modems usually don't work very good....
i know much people with usb adsl modem having problem like that.....
you can try to install a different driver version of the modem....
and contact the support of your modem....
or you can tell us the exact name of your modem so we may find something interesting for you

i know this is stupid.. but when the issue occur have you tried to unplug the usb from your pc and plug it again in ANOTHER usb port? many USB ADSL modem goes OK doing such a thing..... i sincerly don't know why....
bye...

Hi mastrominchione,
I will try the "plug it again in ANOTHER usb port" plan and see what happens and will also get the exact modem name and post it here tonight. Contacting support is not a option since the only support available for this modem will be either BT(British Telecom) or AOL. Since I am using it to connect to Virgin, they will not help me, trust me. The only other option is to try the chipset manufacturer (the name that i will post here tonight) but i believe they don't deal with the public. Will try anyway.

Thanks

Hi again,

Modem name: Globespan USB ADSL LAN Modem ( this is however listed under network adapters and not modems in device manager)
Part of the driver setup also installed a PPPoEWin Miniport adapter, if this helps.

Hi

I have now tried the following:
1. Unplugging the USB cable and plugging it into another USB port.
2. Turning off Windows Firewall
3. Anti-Virus disable
4. Restarting

None, including the restarting works. If the phone cable is unplugged while it is connected and then plugged back in, I am unable to reconnect. Not automatically, not manually and not by trying any of the above. The only sollution is still to go to "Network Connections" and the to run Make New Connection Wizard.

This i think indicates a windows and not an ISP problem.

Any ideas of what to try next?

al-hasanCommented:
Pieter: not a solution, but a solace for you. Seems to be a Windows problem indeed, and I had the same issues with a LAN modem, so it should not be a USB problem as well. In my case a reinstallation helped, and I do not use the Windows driver for PPPoE. Have a feeling this is a problem of the driver or TCP/IP-stack, just have no clue how to update the later. Any other help?

GlobeSpan is a tecnology.. my modem use that tecnology too... but GlobeSpan USB ADSL Modem it's not the real name of your modem...
i have a Michelangelo USB ADSL Modem.. wicht have GlobeSpan tecnology.. it's an orange little modem with 2 red led.. one for power and the other for the adsl link...
when it light on start to winkle until it can estabilish the connection.. then it stay fixed there!
right-bottom my desktop there is the 2 arrow icon that i think you have, too.. when the modem it's not plugged in or not recognised they are RED if the modem it's recognised but there is no cable the icons are Dark Yellow.. then they start to winkle Yellow when it is tring to connect.. and GREEN when connected...

some times it got 2-3 minutes before it can reconnect if i unplug the camble... depends on your ISP traffic.

you said you have to make a new connection in Network Connection.... but... you are not touching the driver when you do it....

it's better if you uninstall completly your driver....
then unplug the modem and restart
then put in your driver installation disk and execute it... DON'T plug the modem in until asked....
i think you have to choose from 3 different type of installation... WAN, LAN and ATM...
there are little difference from that... i usually do WAN
at the and it will create on your desktop a connection icon...
then you can use that to connect with user and password... without go to network connection....

if you unplug the phone cable and than plug it again it should reconnect (GREEN arrows and lighted LED) after a while...
if you see it that try this mean there is a connection... and can be it's only very busy...

this is really strange.. i never heard of it...

when this happend the connection it's still in the Network Connection? if you try to use it what's the error?

Hi Pieter,
  Carrying on from mastrominchione, also want to emphasise that u use the dialer made by ur modem driver. It is best to unplug modem, delete/uninstall driver from Control Panel & then reinstall it.
  This generally solves problems for Alcatel modems which are similar to the one you have. BTW USB modems are not routers & I personally have had a few issues setting them up as well.
  Also note that since these are powered directly from ur PC USB port, the mobo may not have the ability to allow such a high current thruput & can cause malfunction
Id suggest u also uy a powered USB 4port hub & then plug the modem into that instead of directly into the PC

Good Luck,
Zubin

Hi,

Ok so if I understand correctly, the next step should be to uninstall the modem driver, unplug the modem, reinstall the modem software cd and wait for it to ask before I plug the modem back in?

BTW, Globespan is a chipset manufacturer, the name on the modem is "BT AOL Voyager", the name in "device manager" is Globespan USB ADSL Modem.

Yes, mastrominchione it is very strange, because the modem itself reconnects to the ISP, hence the green arrows and the lights on the modem as explained earlier, but the part were i have to supply a username and password to authenticate on the network fails. So the modem is connected, but I can't authenticate. the place/way in which i authenticate is through creating a connection with "New Connection Wizzard" which you can find by right clicking on "My Network Places" and the going to properties. Lets call this new connection "ConnectionA". The first time that I then connect using "ConnectionA" it works fine. If I then remove the telephone cable and then plug it back in and wait for the modem to reconnect(green arrows) then I use "ConnectionA" again and it does not work. So if i then go and delete "ConnectionA" and recreate it, then I am able to connect.

yes.. this is the next step
before reinstall reboot your pc!!!

ok... so the modem works i think...
when the connection don't work.. what's the error? this is important becouse it can put us in the right direction

so
1) uninstall driver
2) unplug the modem
3) reboot
4) install driver (don't plug the modem to the pc!!!) (i normally choose the Wan installation)
5) only when asked plug the phone cable to the modem (if it isn't yet), and then the modem to the pc
6) at the end you will see a new icon on your desktop... use that icon for connect with user and password don't try to create new connection at connection wizard
7) when connected test your line as you wish
8) try to unplug the phone cable
9) replug the cable
10) try to reconnect using the icon on your desktop (reinsert user and password)

if it work... it's ok now... next time you connect to internet select remember user e password and reinsert again them for the last time

if don't work copy exactly here what's the error
good luck!

Hi,

I tried the step as suggested by mastrominchione. It did not work because I am using an AOL Modem and Aol Broadband CD to try and connect to Virgin Broadband.

Really i promise i did try the steps, but they can not work. I can only install the modem driver from the AOL cd then i must have a Virgin broadband CD, which i don't have. So I must make the connection with new connection wizzard.

If you do not understand or know of the difference between "AOL Broadband" and "Virgin Broadband" and the problems of using "aol modem" on "virgin broadband", you can not help me.

Thanks anyway, i really appreciate it.
End of story, if there is no other advise available i will be closing this call in 48 hours, and start saving up to buy better equipment.

Pieter: sorry if cfos did not improve your situation. Over here it did help, and - since I did a new installation of Windows - I can pull the cable and plug it in again, without any problems. The connection will be still there, if the interrupt is only a few seconds. But then the same happens when using Linux, so it is not because of the cfos, true.
Guess you should replace the whole TCP/IP-stack, but cannot tell you how to do it.

Hi al-hasan, yes i can seen that if the cable is only unplugged for a few seconds, it might not be a problem. In any case i have searched around on this site and i think i might have asked this question in the wrong area. There is a topic area dedicated to broadband asdl connections under networking. will try that out.

ohhhhhhh.....
now i understand!!!
why don't you said it from the beginning?

ok... first of all.... i suppose your modem it's one of this:
http://www.voyager.bt.com/faqs/usb_index.htm
please take a look and let us know wich one...

now...
you have been AOL Broadband for a while and you bought a the kit from them (with the BT ADSL USB modem included)
i found the follow information on the net (becouse im italian and don't know your provider) notify me if something wrong!
when in AOL you don't need to login.. you are "always" connected.. isn't it?
when you go to the Virgin Broadband they have their own kit.. with an expencive alcatel speedtouch modem....
and, as i understanded searching in google, Virgin.net don't do assistance if you don't buy their kit..

the difference with Virgin.net it's you have to login i think...
anyway..... why you have PPPoE (PPP over Ethernet)? are you sure?
becouse usually they use PPPoA (PPP over ATM) ...

can you give more details? i think the issue it's in some detail you miss...

why don't you ask to move this post in networking section?

don't care if your modem it's not the alcatel one... but cant use the installation disk of virgin or aol
when finded the exact model goes to the
http://www.downloads.bt.com/
and download the new driver for your modem.. then uninstall again, reboot and install from this driver (don't plug the modem until asked)
you have to be sure if you have PPPoE or PPPoA (you chosed one when you buyed their adsl)
again... usually in installation process there is WAN installation....
and i found on net that...
Typical settings for ADSL in the UK are as follows:
VPI = 0
VCI = 38
ADSL Modulation Auto, then try G.DMT, then try ANSI T1.413
Encapsulation Mode PPP over ATM (PPPoA - RFC2364) VC-MUX  <---- this is becouse i ask you if you are sure
Service name Home 500
Authentication CHAP
MTU = 1458
Receive Window (RWIN)

try this driver........
hope that this help....

Hi again mastrominchione,

Now you understand the problem. The PPPoE is installed automatically when you install the modem drivers with the AOL CD, I can not choose. So will download the drivers from BT site and install to see what happens. Yes I am positive it does install PPPoE and not PPPoA, it does this by itself, I can not choose.

Yes with Virgin.net you have to login, that is why i have been using "create new connection wizzard"

Will see what happens after i install the new drivers.

Cheers,
Pieter

Hi mastrominchione,

Yes, it worked! Thanx for your advice and patience. I almost gave up to be honest.

The driver that I downloaded form BT works completely diferent from the one that I had installed. It shows 2 ISDN channels in the "connect using" part of the general tab if you go to the properties of the connection. One is ISDN Channel - BT Voyager 105 ADSL Modem(this is the one sellected to be used) and the second one, ISDN Channel - PPPoEWin Miniport(this one is not selected to be used  for the connection)

Both are new so both was installed(created) by the driver. Well as weird as that is atleast it works.

So thanks again
