Currently my parameteres are:

@darant 

hello I  tried to install in my archer V1 and impossible to flash.

My current firmware is 1.2.0 0.9.1 v0001.0 Build 200511 Rel.44954n

Thanks

Well, this is fantastic! After version 2 got a new firmware file again, does version 1 stay that way? Incredible. :(

After several tests with this awesome beta firmware

Stability.. 0 reconnections in 24 hours or inclusive more days.. etc...

In Spain (Extremadura)  Orange company, I can say the best combination are:

BAND A/B

3/5

3/7

3/8

3/20

3/28

3/38

3/40

8/3

20/3

Rest of them, or disconnected or slower speed.

Thank you so much

I have chosen bank 3 & 40, but it always connects to 40 & 40 why? refer to the screen attached. 

earlier a few months back it's used to connect 3 & 40 properly for the same settings only then I will get good up/down speed. 

So now, I able to connect either with 3 (setting band B = empty) and 40 (setting band B=empty) separately. 

whereas 3 & 40 aggregations are not happening, even if aggregation failed, it should connect to only one bank 3 or 40, should not be 40 & 40 as per setting, right?

please refer to the screenshot and suggest.
