Network manager Crashing on Ubuntu

I have been using the Airtel GPRS to connect to the internet for my mobile as well as for my Ubuntu linux box. Recently i i am getting problems. The internet gets disconnected and reconnects and sometime it will not reconnect. I have even received crash report sometimes which indicate network manager is crashing. Can Anyone help me solve Network manager Crashing on Ubuntu? Please help...

Is it happening only with the Mobile internet connection or even if with anyother internet connection? Internet connections that is GRPS disconnects when there is GSM data flowing inwards or outwards. This means a disconnection is possible if you get a call or a message. Check this is not your case. Do post back... :thumbup1:

Well i know that if i get a call or message the GPRS data is interrupted and if the duration is long it may disconnect. But this is not my case. I don't understand what goes wrong. Well i don't have any other internet connection to check it nor a local area network. So i don't know about any other internet connection. Can anyone help me with this? :crybaby:

Whenever you experience this problem simply try to restart the Network Manager, that might get the internet connection work again, but you will need to connect again. The command is :

To view the status :

Code:

---

sudo /etc/init.d/NetworkManager status

---

To start :

Code:

---

sudo /etc/init.d/NetworkManager start

---

To stop :

Code:

---

sudo /etc/init.d/NetworkManager stop

---

To restart :

Code:

---

sudo /etc/init.d/NetworkManager restart

---

To force restart :

Code:

---

sudo /etc/init.d/NetworkManager force-reload

---

Hope these commands help you... :thumbup1:
