How do I check the Wi-Fi chip in DWA131?
8
I will now install the Wi-Fi Analyzer. The screenshot... my Wi-Fi is MSUC0096
DWA131?
An USB 2.0 device. USB 2.0 has raw bandwidth of 480Mbps. USB 2.0 has 20% protocol overhead. Effective bandwidth available is 384Mbps. No bottleneck as your DWA131 raw wifi bandwidth is 300Mbps.
Unfortunately....from your wifi analyser screenshot.....you will have hard time getting that effective 60% of 300Mbps bandwidth....
You are sharing your 2.4ghz air time (broadcast time) with 5 different hotspots. Think of it as interference which resulted in non-usable data.
See the edited picture below. The area under the curve is your 180Mbps ( 60% of 300Mbps, remember, wifi protocol overhead ).
I have colored your usable area (bandwidth) in pink color.

If you still remember how to calculate area from secondary school.......then you will know what is your actual effective speed after deducting those overlapping areas.
edit: From rough looking at your wifi analyser result......roughly 50% of your bandwidth is gone from overlapping hotspots from your neighbours.
So....160Mbps divided by another 50% = 80Mbps.........

This is the best case scenario from your screenshot.
Some routers save power by lowering transmit power when not in use. If your neighbour starts to use their 2.4 ghz wifi as well....I imagine the interference will be worse.......
EDIT 2 : In your screenshot, why does your 2.4ghz is connected at 20mhz channel width? Please force 40Mhz at your RGX4400 router. Eh? Silap tengok.
