I have a persistent problem browsing after connecting my GPRS/GSM Module to Raspberry Pi. I bought the GSM/GPRS Module on amazon at http://www.amazon.com/SainSmart-Small-GPRS-SIM900-Arduino/dp/B00TEUAJMQ/ref=pd_sim_147_4?ie=UTF8&dpID=517DbMGK%2B9L&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=17HH346MFMXS37D4TX8H.
I have followed the instructions as given on this site
https://learn.adafruit.com/fona-tethering-to-raspberry-pi-or-beaglebone-black?view=all
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:21.144.145.193 P-t-P:10.64.64.64 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1

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!
