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
