How to connect at least 3 Wi-Fi at the same time?

I'm helping a friend with a MacBook Air (13-inch, 2017) with macOS Mojave v 10.14.6, to activate and connect at least 3 Wi-Fi interfaces at the same time. First, a bit of context... We are in Venezuela with a very crappy internet connections, less than 1 Mpbs in AVG, so we are trying to make channel bonding in order to allow us to use multiple Internet connections simultaneously to optimize performance, we are using Speedify for macOS and it works like a charm! **We have:** - 2 Huawei E5573Cs-609 Hotspots with a SIM card with a mobile data plan. - 2 Smartphones with hotspot functionality **Total:** 4 Available Wi-Fi connections. - 2 External USB Wi-Fi Adapters (TL-WL725N - Version 3). - 1 MacBook's built-in Wireless card. We have installed these specific drivers from here . Running the ifconfig command, - en0 stands for the built-in Wireless receiver (WI-FI). - en4 for one TP-Link USB dongle. - en5 for the another TP-Link USB dongle. Thanks to the StatusBarApp (TP-Link's wireless network adaptor APP), located inside of /Library/Application\ Support/WLAN/StatusBarApp.app/ we manage to active en4 and connect it to a network. In theory we can active a "hardwareport" or "interface" running a this command: sudo networksetup -setairportpower en5 on But this is the output: > en5 is not a Wi-Fi interface. > > Turning on the only airport interface found: en0 So this other command won't work: networksetup -setairportnetwork en5 [password] We found wpa_supplicant inside a folder in the /Library/Application\ Support/WLAN/StatusBarApp.app/ directory, but without wpa_passphrase exec. But there is no problem, on my Linux computer I've generated a wpa_supplicant.conf with 4 blocks like this: network={ ssid="My_SSID" #psk="My_Passphrase" psk=psk_generated_here id_str="Network One" } But I'm not sure how to set up en0, en4, en5 to each network... EDIT: ----- As @nohillside requested, here is the output of networksetup -listallhardwareports, ifconfig en4 and ifconfig en5 commands: mba:~ rob$ networksetup -listallhardwareports Hardware Port: 802.11n NIC Device: en5 Ethernet Address: 50:3e:aa:23:dc:d2 Hardware Port: 802.11n NIC Device: en4 Ethernet Address: 50:3e:aa:23:ad:56 Hardware Port: Wi-Fi Device: en0 Ethernet Address: 1c:36:bb:2f:c3:d2 Hardware Port: Bluetooth PAN Device: en2 Ethernet Address: 1c:36:bb:2f:c3:d3 Hardware Port: Thunderbolt 1 Device: en1 Ethernet Address: 9a:00:13:d9:e0:60 Hardware Port: Thunderbolt Bridge Device: bridge0 Ethernet Address: 9a:00:13:d9:e0:60 VLAN Configurations =================== mba:~ rob$ ifconfig en4 en4: flags=8863 mtu 1500 ether 50:3e:aa:23:ad:56 nd6 options=201 media: autoselect () status: inactive mba:~ rob$ ifconfig en5 en5: flags=8863 mtu 1500 ether 50:3e:aa:23:dc:d2 inet6 fe80::815:e1a5:3023:39aa%en5 prefixlen 64 secured scopeid 0xd inet 192.168.8.103 netmask 0xffffff00 broadcast 192.168.8.255 inet 192.168.8.102 netmask 0xffffff00 broadcast 192.168.8.255 nd6 options=201 media: autoselect status: active mba:~ rob$ We have more than 2 days Googling and trying a lot of stuff with no results (having >=3 active and running Wi-Fi connections) in order to merge it with Speedify (which perform its work very well). How can we achieve this? Thanks for reading.
