Have to use ipconfig /release and renew for internetaccess

Hello, I started having this problem yesterday when my wireless connection showed limited connectivity. After I do the ipconfig commands it works for a while and then I have to renew it again. It is very annoying. The same problem occurs on a different computer.
The router is TP-Link TL-MR3220. I have tried turning it on and off again and resetting it.

Netsh wlan:

Really did not need that information. That only shows that you are pulling an IP and also includes your Public IP info. If this is a wireless issue. Need the info from "netsh wlan show all".

So far I have confirmed that my computer doesn't have the same problem with different routers. The router also does not let me connect to the settings page (192.168.0.1) unless the internet cable connected to it is unplugged. Not sure if that is normal or not. So any ideas?

What is the mfg & model of the router? Who is your ISP?
