Thread: Dail-up hangs [Windows XP & 7]

Hello guys,

Right to point :
i am using windows 7, using my own batch script to prevent idle connections and to do redials if dropped, i face many dsl link drops during day and night time, sometimes windows show dial-up connection is connected but its not, when i try to disconnect it, it won't, finally means the whole windows dial-up software/thingy/api/system (whatever) hangs, but other things in whole OS works fine, the only known way is to restart pc to correct this problem.

it happens in xp also but i am not using it anymore


re-creation:
i can easily recreate the problem by pulling dsl cable from router, means by doing it many times, just put inn - put out ( 10 times or 20 times like that), yes its just random problem, how ?? well i guess it happens when windows recognize that there is connections but its not actually there
or
we can say that sometimes windows can't recognize the disconnection and hangs the window dail-up thingy ( dail-up api technically ) when redialer detects that there is disconnection by pinging the google or yahoo and redials the connection, it creats conflict

what's code in your batch file ?
its just simple command

Code:

rasdial BSNL username password

already tried:
closing known services responsible for windows dial-up, network connections
crashing explorer ( sometimes work, maybe due to unloading of some dll files )
logg-off user and logon again ( sometimes work, not always)


router:
Atrie DB 108
Lan card: onboard lan card, biostar (with amd cpu) & gigabyte (with intel cpu) 2 pc
Cat 5 cable

BSNL details:
plan 750 unlimited
speed 2mbps ( 220 KB/sec all the time)
pole to home wire is new, pair changed already ( 20 times i guess)
employees know me by my voice, they hate me very well !
data usage per month : above 200 GB/month
already tested more than 20 auto dial-up dialers and my some vb/batch scripts


little about me:
Electronics engineer
using computers from more than 10 years
can code in php, python, perl, bash/batch scripting some other little things too
can handle linux/windows servers very well

I hate windows, alas i need them for some particular work !!


My snr is little low then expected, cuz exchange is 5Km away from here

You are in bridge mode. In the bridge mode when the dsl drops wan shows connected status but if you try to disconnect it will take time as it can't connect to pppoe server. post your modem stats if line drops frequently make a complaint to the bsnl.

SNR Margin (dB) 7.7 24.0
Attenuation (dB) 41.0 23.5

see this......wait checking for link.

2.
try PPPoE mode. You have tariff plan.
3.
Modem appears to be similar to New UT300r2u or Beetel 220BX.
4.
try google dns
8.8.8.8 and 8.8.4.4

@mvb4u, thanks for info, but which modem stats ?
u mean this ?

@essbebe, yes i already know that, but its really varies alot, at present snr is changing at each refresh from 5.3 Db to 6.5 db, which is too low
sometimes it goes upto 15 or 20 also, like when i called bsnl last time, it performs very well in front of them so they can't really decide what to do in this matter, they just change pairs and pairs and pairs... they have no clue !!

I mean SNRMargin and Line attenuation which were posted by earlier I didn't noticed, to have a stable dsl connection your SNRMargin should be above 12db but your line has poor SNRMargin figures insist on the line staff to show consistent SNRMargin above 12db.

Same problem!!!!

Still no solution

1.There is no further feedback from other posts./users.
2.From the ipconfig /all data provided by@THIS
(a)the DNS servers appear to be from Delhi. .
DNS change was recommended.

(b)also to check cause of poor snr values.

3.

What is the error message you get error 651 etc ?
4.
when connection is lost modem system log can be checked to find out how connecction failed at that particular time.>
5.
Mention the modem/model/make/number for records.

no error message...when u redial it after diconnection there is no response at all..as it already shows connected
neither can u disconnect it

4.

i dont mind the discn. the only thing i want is that i should be able to reconnect it afterwards

sometimes windows show dial-up connection is connected but its not, when i try to disconnect it, it won't, finally means the whole windows dial-up software/thingy/api/system (whatever) hangs

so no network problem here

5.
Can you post screenshot (jpg)of the Dialer window as annexure ?

6.
As I am On "Always On" PPPoE tried to set up. "Dialer"and experienced same problem. .Windows 7 Professional.

7.
Will set up another modem for "Bridged " mode and feedback later.

for my ref:
http://www.bayan.com.ph/forum/yaf_po...th-Images.aspx

BSNL details:
plan 750 unlimited
speed 2mbps ( 220 KB/sec all the time)

is thr any such plan exists ?? as per my knowledge , plan 750 has unlimited usage with 512 Kbps bandwidth( 64 KBps ) bt not 2Mbps(220 KB/sec all the time)

.:Unlimited Home Only:.

and fr the problem u stated chk out if u hv any joints in our telephone line ( from pole to ur home )

Windows 7 professional SP1..
Set up "Dialer" mode"
seems ok.
(1) clicked the "wifi icon" in Taskbar and selected
"Dialup and VPN"
"Broadband LAN" "connect" to get the dialer window.
seems no problem.
(2)Also created shortcut in Desktop.


Para two:
Ipconfig /all shows auto selected Ip address 169.xx.xx.xx.
"obtain Ip address automatically " selected.

Never used dialer mode due to VOIP/ wifi setup.
Changing modem for normal setup.

Dialup window available even when connected in wifi mode or "always On " mode.


When selected error 651 etc.

Autoconfiguration IPv4 Address. . : 169.254.134.10(Preferred)

169.254.x.x is the default ip to be set by xp/vista/win 7 if you setup the tcp/ip properties in automatic ip mode for the very first time.the way to do it is set the ip to manual,select an ip say 192.168.2.4 & apply.after that you can change it back to automatic & windows will remember to get the ip in the earlier selected range only i.e.192.168.2.x.

Dialup window available even when connected in wifi mode or "always On " mode.

this is also expected.on win 7 multiple network connection are expected so it is designed in this way.e.g.a wifi connection as your primary connection while a dialup as backup.the reason why win 7 failed to recognize that both connections use same modem & thus should give a modem busy error might be because of the presence of wifi router alongwith modem confusing win 7.

There is a"BUG" as reported when we try to use "Dialer" mode.
Stimulating conditions again later.
System freezes as reported.

@essbebe,there should be an option"use this as my default internet connection"in dialup connection properties.uncheck it & then see if it helps.also see that IE is not running while doing these tests.if any doubt then check in task manager process iexplore.exe is not running.

use this as my default internet connection in dialup connection properties....

Not available. Searching ......
IE not used ( not active) .l.... will recheck Internet options /connections
later.

[DIY Tutorial] Setup a PPoE Dialer in Windows 7 (With Images) - Do It Yourself - bayanFORUM

@ OP

Why not try PPPoE ? Is there any particular interest in bridge mode ?

@essbebe,in network & sharing center,on left hand side click on option"change adapter settings".on the new page all network connections will be listed(active/inactive).right click on bsnl dialup connection & you will get option either "set default" or "cancel default".

P.S.@meetdilip,no particular interest in bridge mode even though i prefer it.i am merely interested in this problem.

Problem Dialup hangs
See Post No 6.
Stimulating Dialer Mode in Windows 7 Pro.
As I have VOIP/WIFI usage my modem is set for PPPoE mode only
( userID/PW stored/entered in wan page ).
The dialer window in Post No appears if selected even in this mode.
If I click connect, system freezes.
The "Monitor+Fork"icon is common.


For wifi different Icon.

@whitestar_999
Please see FAQ ( at the end) in tutorial link. already seen .

Question How can I delete a connection?

Answer Open Network and Sharing Center, click Change adapter settings and right click on a connection you want to delete and click Delete.

Assume Dialer mode is made in Windows 7. No other mode. wifi'"always On"
and give comment/s for problem above.

@essbebe,so what was the result of switching between default & cancel default option for the bsnl dialup connection.

@v-na5h
any update?
In modem have you selected "Bridged" mode?


@whitestar_999
Problem is this. Post No 8.
sometimes windows show dial-up connection is connected but its not, when i try to disconnect it, it won't, finally means the whole windows dial-up software/thingy/api/system (whatever) hangs

switching between default & cancel default .....

Wanminport connection . disabled.
http://www.indiabroadband.net/attach...1&d=1305031670

@essbebe,since i don't have a wireless router this the best i can do to test.i connected modem set in pppoe to laptop running win 7 via lan.then i created a dialer for bsnl.after i got connected through lan port showing connectivity as internet in system tray i dialled the bsnl dialup connection.after some seconds i got the error 651 with countdown of 60 seconds to redial.i clicked cancel.no hang ups during this process.btw the pic in your previous post show a green tick over the wan miniport(pppoe)which means it is set as your default connection.you can right click to cancel default.this problem of dialer hanging on win 7 i only experienced while i was using airtel gprs dialup.if you can reproduce this error please give detailed conditions & if possible only using modem & no wifi so i can reproduce it too.
