Find the driver corresponding to the network card model and kernel version, but there are also exceptions. My kernel is 2.6.32, and my Linux driver for kernel 2.6.23 (and earlier ), instead of Linux driver for kernel 2.6.24 (and later), 2.6.24 was reported incorrectly and was not installed successfully.
tar zxvf rtl8192ce_linux_2.6.0006.0321.2011.tar.gz cd rtl8192ce_linux_2.6.0006.0321.2011make && make install
If the version is incorrect, make clean first and reinstall it. After installation, restart your computer. Done
