If you only have 1 Computer that should access the MBL, this solution might be okay. I still wouldnt recommend this.
Allow me another suggestion:
-Buy a 1Gbps Ethernet Switch with WIFI and put it next to your computer (these things are really cheap nowadays)
-Set this switch as WIFI bridge to your router
-Plug in the MBL and the computer to the wired Ethernet Switch
Advantages:
-Full speed access from your computer to MBL
-Also full speed to the internet availible, both from MBL and Computer (assuming WFIF faster than your internet)
-Remote access and LAN access from other computers, streaming clients, smartphones… to MBL availible, both via WIFI and Wire
-no changes in Hardware setup necessary (carrying around the MBL from one room to another, i would be really annoyed )
