i just tried this evening, so still in trial mode.
if u wanna try too, change this value
my default value is -78

slowly change the value till u find optimum value, and dont go overboard as we dont know what will happen if value is overlimit..
different device will have differ value..
and 1 more thing, signal is not everything, but position does matter   
tested device e367, report your finding here         
and i not responsible if anything happen to ur modem

can explain more what this will do to the modem?

Huawei E398 default -2XX 

E372 default is -2xx , but i try -3xx , much better signal



is 15Mbps = 1MBps ?

if not anything wrong with my dashboard ?

its a E372

err.. suppose 15Mbps is about 1.8MB/s..

Thanks, bro. 

I'm gonna kill my E372 anytime with -444 value. 

For the meantime, I don't need LTE because the speed is like graveyard shift and web surfing is F awesome.

guys, what is ur TX value?
the default one or supercharged?

@digilife
what is ur value? -444 too?

i only have zte mf680, still thinking too try or not

Tried with my zte mf680 pair with mr3420 v1 openwrt (got fan blowing to the router and modem)

TX value = 20
NV_WCDMA_VGA_GAIN_OFFSET_1 = -438 from original -238

really stabalize my speed, now fibre connection feel!
even in peak day also speed like graveyard shift

@digilife
you got money, can la 

not abt money, i have a few unuse modems around , moreover if one of my modem failed, i will inform you guys to stop........btw, my e1762 have the best result, from RSSI -95dBm , set to -200 ( default is 80 ) gives me RSSI of -65dBm , speed 4Mbps ( 7.2Mbps modem) , shaved off -35dBm , without Antenna...........

Fiber Like

nice one. Signal strength is even better than antenna.

Now even RSSI can be faked boosted in this way, every modem manufacturer should did this

How is the SNR of you guys after did the tweak

If i add antenna, i wonder how will it fare ( but still too lazy to fix my Dual Panel yet. )

Thanks, bro.
