CentOS 7 | TP-LINK TL-WN725N | Wifi Adapter configuration

Post by andyvirdy » 2017/11/10 04:39:39

I have recently installed CentOS 7 on my PC. I am trying to get the wireless network connection up and running on my PC and have tried many options from the internet on my PC. However my network is still not up.

OS: Linux centos.shekharnambi.com 3.10.0-693.5.2.el7.x86_64 #1 SMP Fri Oct 20 20:32:50 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Wireless Adapter: TP-LINK TL-WN725N

lsusb output

I tried to configure via nmtui and was able to create MyHomeWifi but was not able to activate it

I tried to open NetworkManager but it would just throw the next prompt without any GUI opening up. So I am left with no UI to configure network

Can you please let me know how to get my wireless adapter up and connected?

Thanks
