Installing tp link wn823n, driver problem

I recently installed the pimusicbox software on my Pi1. In order to use the wifi I have the tplink wn-823n wifi dongle. My Kernel Version is 4.14.26+. When I check my USB devices via lsbusb I am getting this

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 004: ID 2357:0109  ** <- WiFi Dongle **
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub

The marked one is the wifi dongle. I already tried installing the drivers via the installation tutorial in the Now I haven’t tried modifying the kernel source because the dongle should work with my kernel. So I skipped that step. But I’m getting errors at the last make at 2.2. (Page 8 in the pdf). The make clean worked without errors.
