1) This is for developers and advanced users who know what to do.
2) Do it at your own risk. I am not responsible to any problem due to this modification/hacking.
3) I am not showing how to change/edit the file.
3 days ago, I did a change in /system/etc/ppp/peers/pppd-ril.options.
This is the orignal content of the file.
nodetach debug noauth defaultroute usepeerdns connect-delay 1000 # Don't remove the user/password lines. They are required to make PPPD authenticate itself with # the BP when doing Simple IP (SIP). The BP will replace the user/password strings with the correct # values when authenticating to the network-side PPP peer. user NotUsed@nobody.com password NotUsed crtscts lcp-echo-failure 0 lcp-echo-interval 0 ipcp-max-configure 30 ipcp-max-failure 30 ipcp-max-terminate 10 novj linkname ril
Before the change, I got (down/up) 3.4/0.5 Mbps, but, after the change, the result is quite impressive as we can see in the screenshot. Sometime, I got about 2x of download speed when download podcasts MP3s, from 400 kBps to upto 800 kBps.
Mbps : Mega bit per second
kBps : kilo BYTE per second
Anyone who tried this hack/mod
Remember to reboot after changes
$ man pppd
If your device does not have the file, you can try the hack which I posted in post number 100.
As ussual, please report your findings. Remember to put your device name, U/D speed before and after the hack.
