hi and good day to all
i had installed the raspbian with kernel [5.10.103], and following the command
curl -fsSL https://raw.githubusercontent.com/nexmonster/nexmon_csi_bin/main/install.sh | sudo bash

the nexmon was installed, but no phy0

there is no device. Empty

How did you install raspbian with kernel 5.10.103? Afaik, no raspbian image ships with 5.10.103 as default.

But if you're sure the installation went well, try restarting the Pi.

the installation went well..it works well with header of 5.10.93, but when in the base file there is additional header [5.10.103-v7+.tar.xz], and it is also installed well...but it deletes the wifi physical driver...and yet i could not solve it.
i want to use the raspberry pi with header of 5.0.103 since it is supporting other router attached with pi where the 5.10.93 does not...
any idea how can i install the phy0 back?
