Wifi weak signals with RTL8723BE since kernel 4.15.0-33

Post by mint4242 » Sun Sep 23, 2018 4:36 pm

Hi, I can confirm that changing the kernel to 4.15.0.32 (instead of 4.15.0.33) resolved the issue on my HP laptop.
Note: I have to use modprob option ant_sel=2 on my HP 17-by055ng.

You could take my word for it. You could look at the bug report, see my comment #18 and see comment #21 about what was changed for the test kernel that worked for people. An alternative to not updating kernels is to use https://github.com/lwfinger/rtlwifi_new as that doesn't have the issue but you will need to disable Secure Boot

I'm confused. Did this fall out of another thread?

Also my rtl8723be works fine with the 4.18 series and every other kernel I used it with so far. /shrug

Oh, forgot, split from viewtopic.php?f=53&t=277764

gm10, I would guess you don't have a newer HP laptop

Nope. Mine's an Asus from last year.

I'm not sure why you split this off but if this is supposed to be a guide or PSA post for HP laptops maybe indicate that in the subject line so nobody else gets confused.

About 3 years ago HP started using just one antenna wire on the rtl8723be wifi cards, and now they are doing the same with the rtl8723de cards
