I have a persistent problem browsing after connecting my GPRS/GSM Module to Raspberry Pi. I bought the GSM/GPRS Module on amazon here.
I have followed the instructions as given on this site
The results were as expected. I obtained the local and remote IP address needed, i got the DNS addresses too.
Running "ifconfig", i have the result below which clearly shows i can communicate via ppp0.
ppp0 Link encap:Point-to-Point Protocol inet addr:18.104.22.168 P-t-P:10.64.64.64 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:72 (72.0 B) TX bytes:111 (111.0 B)
The problem now is that i cannot successfully ping any IP address. I keep getting "Networking not reachable" or "unknown host" in case of a url.
More so, the LED light that shows the connection is meant to be blinked twice each second but stops blinking after ppp connection in established.
Please if anyone has a suggestion on what might possibly be causing this, help me out!
