Netgear n300 ex2700 wifi extender says password is incorrect

[BenParkes]

Hello

Basically my router says "incorrect password" even though it is definitely correct. So I factory reset the router, reconnect to the router using the WPS button and it works again. Then after about a week it will start saying incorrect password even though it is definitely correct. The firmware is update. Does anyone have any suggestions? Thanks in advance.

Suggestion 1? Factory reset the extender and re-run setup using the installation assistant and not using wps. wps gets coded different between different manufacturers.

Hi, thanks for your suggestion. How do I set up using the installation assistant?
