Reconnect issues

[Soulcode]

I have been having this problem for months now:
Once i connect to the internet i run an ipconfig and get this:

Windows IP Configuration


Ethernet adapter GAMES:

Media State . . . . . . . . . . . : Media disconnected

PPP adapter GPRS Only Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 10.15.144.165
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 10.15.144.165
DHCP Class ID . . . . . . . . . . :


Which is perfectly normal, but if i disconnect or get disconnected and run an ipconfig it shows this:

Windows IP Configuration


Ethernet adapter GAMES:

Media State . . . . . . . . . . . : Media disconnected

PPP adapter GPRS Only Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 0.0.0.0
Subnet Mask . . . . . . . . . . . : 0.0.0.0
Default Gateway . . . . . . . . . : 0.0.0.0
DHCP Class ID . . . . . . . . . . :


To my knowledge a disconnected dial-up connection should not report any IP address.

And when i reconnect and run an ipconfig i get this:

Windows IP Configuration


Ethernet adapter GAMES:

Media State . . . . . . . . . . . : Media disconnected

PPP adapter GPRS Only Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 0.0.0.0
Subnet Mask . . . . . . . . . . . : 0.0.0.0
Default Gateway . . . . . . . . . : 10.15.144.22
DHCP Class ID . . . . . . . . . . :

PPP adapter GPRS Only Connection:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 10.15.144.22
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 10.15.144.22
DHCP Class ID . . . . . . . . . . :


This ofcourse leaves me with a completely usless connection. So everytime i disconnect or get disconnected i have to reboot before i can connect again. This is what's giving me the extreme 3G/GPRS headache.
Anybody have an answer for this?

ipconfig /release
ipconfig /renew

Have you tried this?

 

[Soulcode]

Yes, it doesn't work on dynamic IP dial-up(thats what i think anyway):

Windows IP Configuration

Adapter GPRS Only Connection is not enabled for Dhcp.

Well, it should be, otherwise you won't get a proper IP, or am I missing something here?

 

[Soulcode]

It is set to receive the IP address automatically. Therefore i believe /renew & /release doesn't work.

That is exactly what release renew does ... release the old IP (maybe it was a bad one), renew the adapter to receive a new IP from the DHCP server

 

[LandyMan]

Adapter GPRS Only Connection is not enabled for Dhcp.

Then I don't understand this statement, if you say it is enabled to receive the IP automatically?

 

[Soulcode]

Because it is disconnected it cant send the server a request to renew the IP, thats what i think. And it cant just choose one because it has to get it from the server.

 

[LandyMan]

Aah, so thats what I missed .. the fact that it is disconnected

 

[Soulcode]

Yes LandyMan

Not sure if this will help ... But try my 3G Dialer (http://mybroadband.co.za/vb/showthread.php?t=24019). If you have a disconnect it will reconnect automatically. It kept me semi sane ...

 

[Soulcode]

biometrics, reconnecting automatically still leaves me with a useless connection.

lol, Bio, "selling" your dialer at every chance

I've had this exact same problem, but with my ADSL. I fear it's a Win XP bug. After certain software, updates, patches etc have been installed, it seems to stick onto the routing table. I reinstalled XP for this exact reason. I found no other way. BUt you're more than welcome to try. :]

 

[Soulcode]

Thanks TigerTael, i wish there is another way though....

 

[Soulcode]

I emailed a Vodacom techie, I hope to get this sorted out finally.

Because the techie has ignored me for about 2 weeks now.

Actually, LandyMan is correct with this one guys. An ipconfig /release then ipconfig /renew should work. DHCP works via UDP on port 87. Once you have estacblished a PPP or similar connection, UDP traffic will be forwarded for DHCP requests irrespective of whether you have a valid TCP stack or not. It does this via a UDP helper on the network side.
So, what I would check : when you lose your IP - does windows still report an active connection via PPP? If so, renew your IP. If it says you are disconnected at the windows level, then you will need to re-establish the PPP connection first so that you can get an IP addy.
By the way - this is actually normal reporting behaviour for Windows XP... (reporting 0.0.0.0 when there is a break in communication). It assigns this address temporarily whilst it broadcasts on port 87 for a DHCP server, and if it cannot find a server to acknowledge, it will configure you on a 169.x IP address meant to make home networking easier.

I finally found the problem! Zone Alarm was freakin causing it.
