Upgraded network card but I don't get the expected speed of 433mb

[redharel]

I bought new adapter which suppose to get me 433mb speed but for some reason I still get the old 150mb.

I will add that I used the antenna I already had and I didn't do any driver update as I can't find one. What can be the issue?

Hi:

I assume that you are using a dual band AC router?

A dual band wireless N router will only provide a max throughput of 150 MBPS on the 5.0 GHz Wi-Fi band.

This is the latest Wi-Fi driver for that model card.

I have the same model wifi adapter in two of my HP notebooks and it connects at 433 MBPS like it should.

I once came across a similar post where the person had the same issue and it turned out that they were no broadcasting their SSID and once they did, it connected at a faster speed, but still not at 433 MBPS.

Why that would be, I have no idea. 

The person also changed a setting on his router to the 80 MHz bandwidth and that finally got the card to work at 433 MBPS.

Actually I use Xiaomi AX3000.

OK, then the only suggestion I can offer would be to read through the discussion I posted and make sure that you are broadcasting your router's SSID and have the bandwidth set to 80/160 MHz or auto allowing those frequencies.

I also have an AX router (ASUS 11000) and both of my RTL8821CE wifi cards are connecting at the maximum advertised speeds.

BTW the driver update didn't help.

My mistake, the driver did help 😀

I forgot the basic of restarting.

Thank you very much

You're very welcome.
