Did you see "Next" button on that page? If not, provide a screenshot.

It won't. You can still upgrade the beta firmware I mentioned. :)

Jeeprock wrote Thanks Tony but my problem is that the guest network can only have one schedule ! Yeah, I didn't realize that... By the way, thanks for sharing the trick, lol...

There is a beta firmware to solve such a problem and it is for V1. Download it from the link below, upgrade it and have a test. http://tp-link.com/resources/software/TL-WR841HP_V1_141208_Beta.zip

I heard that TP-LINK will release a new utility for all of their powerline devices in the near future. :)

They ask you try different drivers, right? lol... As the adapter doesn't work like a router, if there is a problem with the adapter indeed, it should be a driver problem.
