If this doesn't work check to see if you're getting the same exact IP before and after you do this. I say this because I got the same IP after /release & /renew. So I went into my router's setting and manually set my IP address to a different IP using DHCP reservations. I would explain how, but it varies from router to router. In general, you can access most routers by typing your default gateway into a web brower's URL field. When you do /ipconfig it shows you the default gateway, which for most routers is 192.168.0.1 or 192.168.1.1 (which is mine). But some routers come with their own software to change router settings, and the default password will differ based on the manufacturer/model of the router and whether or not you have received it or changed it before with some kind of provided setup software. This was the case for me, so I had saved my router password from when I set up the router with the software, and I have to launch this specific web interface tied to an email login. YMMV, and lastly I should mention this is a bit more of an advanced solution for more technically skilled users.
