So recently i just bought a new alfa awus036ach usb 3.0 wifi adapter

further information can be found in the link below

______________________________________________________________________

and there is some weird freaking issue to me when im using the usb wifi adapter....

i tried to connect to the SAME SSID(hacked my neighbour wifi) with my laptop default wireless adapter and the Alfa wireless adapter.

turns out alfa has the best signal strength since is equipped with a high gain antenna.


but when it comes down to connection speed and the stabilization of the wifi, my laptop default wireless adapter is more fcking stable than the alfa wireless adapter, although it only 3 bar but still the connection and speed of the wifi wont drop and disconnected.

image attached below
this is my default wireless adapter

speedtest (i can actually hit 10mbps...just that sometimes will drop due to signal strength)

THIS IS CONNECTED BY USING ALFA WIRELESS ADAPTER. IS FULL FREAKING BAR, AND LOOK AT THE SPEED! IS 300MBPS BUT IS NOT STABLE! IT KEEP PLAYING AROUND WITHIN THE RANGE 100-300
Attached Image

speedtest...cant even complete and speed is always capped at 50kb/s

tried everything i could... reinstall the driver, google and still no solution.
USB wireless adapter is running in USB3.0 port

but when i tried to connect my own YES 4G Zoom with the ALFA...everything runs smooth! speed and stability of the connection is excellent!

is there something i need to configure my ALFA??

High gain antenna is meant for directional reception. You will need to point it to the router/AP to get the maximum signal.

While for laptop, it is usually low gain, aka omnidirectional, receives the equal amount of signal from all directions.

i thought is a omnidirectional by itself...... what if i purchase an aftermarket high gain omnidirectional antenna? will it solve the problem?

You could start by buying your own internet plan.

High gain = directional
Low gain = omnidirectional

High gain omnidirectional doesn't make sense.
