Ever since i got my Z (6002), i've had a problem on the 2G (Edge) connection. HSPA/HSDPA was fine, but the 2G connection was virtually non-existent. I always get page time outs and no indication of loading, no matter what app or browser i use.
i was forced to leave the network settings to wcdma only. however, this is not practical since once i get to 2G only location (yes, those places still exist
) i lose all signal until i set network to wcdma/gsm or gsm only.
So after a few days experimenting with the build.prop, if any of you guys have the same problem or want to boost your 2G/3G connections, this is what i did:
ROOT REQUIRED! (be sure you have atleast a rudimentary know how of editing the build.prop)
ADD/Append the following at the end of the build.prop, save and reboot:
Haven't done a formal speed test, but my 2G internet is now working and WCDMA mode feels snappier.
Regarding HSXPA=5. still testing with different values. 5 for my XZ and network seems to provide the snappiest page load.
ro.ril.enable.dtm=0 << this seemed to be the main fix for my 2G/EDGE problem.
I'll let you folks do the speed testing. Just remember that some settings are network dependent and mileage will vary.
Some explanations:
HSUPA >> http://en.wikipedia.org/wiki/High-Speed_Uplink_Packet_Access
HSDPA >> http://en.wikipedia.org/wiki/Hsdpa
HSXPA >> [0=UMTS] [1=HSDPA only] [2=HSDPA & HSUPA]
ro.ril.enable.dtm
Enable "dual transfer mode" on EDGE networks; requires different GPRS class setting. Only set this to 1 if your network allows simultaneous transfer of Circuit switched (CS) voice and Packet switched (PS) data over the same radio channel (ARFCN).
