My goal is to have my pc connected via cable to a router running OpenWrt (a TP-Link TL-WR740N/ND v1 to be precise) and have that router join a wireless network (which is connected to the internet) as client. I want this setup to give my pc access to the internet and preferably give other devices in the wireless network access to my pc. At one point I managed to give my pc access to the internet, however I misconfigured my router and ended up resetting everything...
So far, I've tried the relayd tutorial (https://wiki.openwrt.org/doc/recipes/relayclient), but I couldn't get it work. I believe I had the masquerading working at one point, but I honestly don't remember since I pretty much spend the whole day changing various settings...
My current Firmware version is OpenWrt Barrier Breaker 14.07 / LuCI Trunk (0.12+svn-r10530) and the Kernel Version is 3.10.49.
I'm looking forward to any advice on where to go
