Is this an HP laptop? They have produced systems with but a single antenna. That is OK, but they failed to program the EEPROM to match the antenna that they actually are using. Perhaps other vendors have made the same error. In the rtlwifi_new repo, switch to the rock.new_btcoexist branch, build and install it. Then load rtl8723be with the "ant_sel=2" option. That should fix the problem. I am working on finding a fix for the mainline kernel, but that is not easy as that branch and mainline have very different versions of btcoexist.

Yes, this is an HP laptop. Thanks for the hint, we will try it. Yes, it works now with the driver built from rock.new_btcoex and "ant_sel=2" option set for rtl8723be. Our users are really happy again :-) Thanks a lot! |
