I am trying to enable modem on ANDROID ICS 4.o.3
I am able to get PPP interface in netcfg with IP If I launch the ping www.google.com from terminal I am able to get continuous resoponse but if I launch the browser the ping is giving the error
ping: sendmsg: No buffer space available
and browser also not loading more than one page for the second page it is keep on loading and at the end it is saying a network has occurred ping: sendmsg: No buffer space available and some times browser is trying for long time and it is giving a pop-up window saying A network error occured
In ppp_async.c OBUFFSIZE is 4096 I tried with 10240 also but it didn't worked
and I tried echo 83886080 > /proc/sys/net/core/wmem_max then also same problem
the tcp buffer sizes in init.rc are
setprop net.tcp.buffersize.default 4096,87380,110208,4096,16384, 110208 setprop net.tcp.buffersize.wifi 524288,1048576,2097152,262144,524288,1048576 setprop net.tcp.buffersize.lte 524288,1048576,2097152,262144,524288,1048576 setprop net.tcp.buffersize.umts 4094,87380,110208,4096,16384,110208 setprop net.tcp.buffersize.hspa 4094,87380,262144,4096,16384,262144 setprop net.tcp.buffersize.edge 4093,26280,35040,4096,16384,35040 setprop net.tcp.buffersize.gprs 4092,8760,11680,4096,8760,11680
* My board is having 512MB RAM is it ok for ICS or it can be cause for this problem
Did anybody faced this problem any suggestions to debug this

There is not enough information here. Are you using a umts/gprs module connected through the serial line or are you using an usb modem?
Can you give us more details?
