2 years ago By the way, why does my USB dongle has 2 MAC addresses? I understand one is for 5Ghz and the other for 2.4Ghz. Which one should I use for each AP? I tried with both of them and I get the same results.

2 years ago Hi @Deses
I need to slow you down just a minute. We all have to learn and ...
I'm using Mint 20.3 and I used the GUI to set my two wireless AP as following:
A single usb wifi adapter cannot support dual band because it only has one radio. Dual band Wifi routers/access points have two internal radios.

2 years ago Ah, bummer. When I had a read at Concurrent Mode my understanding was that I could use both radios at the same time. :P
Well if that's the case, I'll disable concurrent mode and just live with the 2.4ghz network. Maybe I'll get a proper AP down the road. :)
Thank you for the help!
Hello, I have a generic Amazon 8812bu dongle and I'm having some issues.
I installed this driver without any issue. I selected Concurrent_Mode during install because I want to have both a 5Ghz and a 2.4Ghz AP.
I'm using Mint 20.3 and I used the GUI to set my two wireless AP as following:
But as far as I see, the access points are working in 802.11n mode only, not ac. And the bit-rate is way too low, 144.4 Mbps is far from the advertised numbers (
5GHz (867Mbps) / 2.4GHz (300Mbps)). I verified this by connecting to the networks with my phone and seeing that the AP is "WiFi 4", not 5.Rebooting or doing
$ sudo systemctl restart NetworkManagerdoesn't make a difference.This is the output from iwconfig:
See? both AP are using
IEEE 802.11bgn,Frequency:2.412 GHzandBit Rate:144.4 Mb/s. 🤔My dongle is connected to a USB3.0 port in the back on the computer, directly to the motherboard (An Asus MAXIMUS VI HERO).
I also tried to manually edit
/etc/modprobe.d/88x2bu.confto define my country code and the wireless mode, but this didn't fix the issue.options 88x2bu rtw_drv_log_level=0 rtw_led_ctrl=1 rtw_vht_enable=1 rtw_power_mgnt=1 rtw_switch_usb_mode=1 rtw_country_code=ES rtw_wireless_mode=95My goal is to have a 2.4ghz and a 5ghz network to extend Wi-Fi coverage to my garage where I have some smartplugs that need 2.4ghz Wi-Fi but depending on the day they don't have a good enough connection. The 5ghz network would be used so phones and other mobile devices don't drop connection when they are brought to the garage.
The computer I'm using for this task is an old Intel i5 4670K based computer that I'm using as a "small" server and it's connected to the network using ethernet and it's getting a stable Gigabit connection from a nearby switch.
