I will do any one of the following tasks in this gig
I will teach you how to install any linux distribution e.g. Debian, Fedora, CentOS, Ubuntu, Mint etc. I can help you with Linux related other problems too.
If you want to install and configure OpenWrt linux on your router, I can also help you doing that. But your router should be compatible with OpenWrt. If you are unsure, then send me router model first before placing order.
