Mywifiext local is a web address which a user must come across especially while configuring the range extender for the first time. If you are trying to access the Mywifiext local website from your web browser but couldn’t do so, then there can be certain reasons behind it. First of all, we want to mention here that this is a local website but not an internet address which opens like other websites. When you open this webpage, then Genie or configuration assistant for the range extender will open on the screen.
If you are still not able to open the link, then check if the device is connected physically to the extender or not. If not, then connect it physically. Check the error message you are getting on the screen. Try accessing other websites on the browser. If you can open them, there is certainly a problem with the connection.
Check the spellings you entered in the web address space. If the spellings are wrongly entered, then you will be directed to the wrong page. Try entering the same web address in an alternate browser.
Check if the router and the extender are connected properly to each other or not. Check the power LED on both the devices, if it is blinking, then it means the extender is not set to work in ideal condition. If you are still facing the problem, then it is good to consult experts.
