So the easiest possible way to get this up and running properly is going to be as follows.Follow step one of the manual - You want to initialize the connection to your router to the closest outlet you have. Don't worry this is just to simply signal transmission.Once you plug it in leave it be until its solid green. In the meantime it might be a good idea to make sure that Mesh is enabled on your router to keep this brief.Now once its glowing green you are going to want to skip to the arrow pointed in the last image I uploaded of the manual; connecting through WPS. This is going to be the fastest way to confirm the two devices want to communicate. First press the wps button on the router, some models will let you do this through the browser configuration somewhere in the wireless settings. Once WPS button is pushed on router, go to the extender and press the WPS button on it in order for them to link. It will be the only pressable button on the front of the unit. Just pressing for a single second will do. Give it a minute or two to fully connect to your network and from there you will be able to relocate it.Next relocate it to whichever outlet in your living space you originally intended for it to be. It will load up by itself but give it a minute or two. If you are intending to connect an ethernet to the bottom port and lead to a device now is the time to do that once its solid green again. You're technically done at this stage but for security I advise you do one more step.Log back into your local router ip on a web browser. Look to see the device is discovered and it should even be in the mesh segment of your router. It will show up but your hard-wired connected device isn't going to necessarily correspond as a direct link. In the same menu of the mesh segment, simply click on the extender device along with the info displayed with it. This allows you the opportunity to assign the IP of the hardwired device you set up to be linked to the extender. Make sure its the right device, and then it should automatically take you to the ip page of the extender itself.Now once your in the UI for the extender you will want to do a few things and your good to go. Since you configured using WPS the account/pw will be the same for your router. Feel free to go through the settings, but it's only relevant to see that the two devices are connected. Note the IP of the extender.Make sure you're signed into your TP-link account, and navigate to the system settings. Simply set the time zone to the correct setting. After that, in the same, system category, you are going to want to go to firmware and click upgrade. This will go through a rebooting process that might boot you out of the account, in which case clear your browser cookies, close the browser, and re open it. Type http:// whatever the ip address of the extender is and you will be back at the menu to sign in.The last two steps are to first, bind your TP link account to the device, so you have administrative control over it. Lastly, go back to system settings and create a backup of the configuration you just did and store it a folder you will remember. Once that's done you're good to log out and not only the ethernet powered device, but other mobile devices on your network will now be able to utilize the Wi Fi extension. You are finished setting it up here.I still like to go back and log into my router through the browser, to verify that connections are being made to the extender and it is displaying numbers with and up and down error, meaning that it's working.The installation part is quick, but taking the extra step to make sure it is properly configured for its use case, its firmware is up to date, and that you have administrative ownership of the device, is well worth the extra steps.This isn't the most powerful product Tp-link has to offer, but it does do its job in broadcasting Wi Fi from a different point than your router through your electrical system. This will be the easiest way to get this up and running in a secure manner. Hope this helped. Enjoy the new purchase!
