Hp ProBook 450 G5

having wifi issue on this laptop fro the day first when i bought it it has realtek rtl 8821CE drivers.

i have tried everything including installing latest third prty drivers or the drivers on Hp website for this particular model

i have tried tweaking different setting like enaling/disabling 802.11d changing beacon interval to 110 or 90 from 100 

changing roaming aggressiveness disabling wake on magic packet or wake on pattern match

i also disabled ipv6 from wifi connection settings plus i have change it to private from public

but problem is persistent

wifi goes limited randomly on its own and then sometimes recovers itself sometimes i have to disable and reenable the wifi card or turn off and on wifi again

i also have changed ip from dhcp to static 

now the only option is to change the wifi card

this laptop comes with 2 other intel wifi cards too

would they run on my hp probook 450 g5 or would their be issue of whitelist/blacklist of hp?

plus this realtek rtl8821ce only has 1 antenna while those intel cards have two antennas what about that would it be an issue?

Hi:

Yes, it would be an issue since your notebook only has one wifi antenna.

The Intel cards would need two antennas in order to work correctly.

By any chance, did you try the latest wifi driver that HP has for that model wifi adapter?
