Post by munish259272 » 2020/08/23 10:13:44

Code: Select all

(base) [msingh@centos ~]$ lsusb | grep TP

I have installed the driver 8188eu

Code: Select all

(base) [msingh@centos ~]$ lsmod | grep 81

That card appears to be supported by the rtl8xxxu module.

Code: Select all

[root@centos8 ~]# grep -i 2357 /lib/modules/$(uname -r)/modules.* | grep -i 0109
/lib/modules/4.18.0-193.14.2.el8_2.x86_64/modules.alias:alias usb:v2357p0109d*dc*dsc*dp*icFFiscFFipFFin* rtl8xxxu
The future appears to be RHEL or Debian. I think I'm going Debian.

I know there is nothing wrong with the password since the same password works for my mobile but it is giving error for PC. I have tried multiple times

Is your wifi access point locked down by MAC address and is the MAC address of this interface in its list?
The future appears to be RHEL or Debian. I think I'm going Debian.
