I accidentally found a interesting feature of TL-WR702N that will allow you to re-configure it remotely. In other words, in Client Mode you can still access the adapter’s configuration page. The trick is that the adapter enforces its default IP address (192.168.0.254), even through it’s connected to a network that has a different IP base (for example, my home network uses 192.168.1.x). So normally you will not be able to directly access the adapter since your computer’s IP address is in a different subnet. However, you can override it by setting a manual IP address, such as 192.168.0.100, which is compatible with the adapter’s subnet. Then open a browser on your computer and type in 192.168.0.254, and you should see the adapter’s configuration page. Different operating systems have different ways to set manual IP address, please Google to find out.
