I bought the RE300 wifi extender months ago to get a better signal to my Ring Floodlight camera on my garage. I has worked fine for months until the other day when I started to have issues with the Ring camera. The signal was becoming very weak and the extender has never changed location, which is in my garage. After spending a lot of time trying to get it logged on again with a better signal, I decided to do a factory reset. I used Tether to try to get everything set up, but I said it couldn't ever make contact with the Main Connection to wifi. Then I used the WPS method on my router and was able to see the EXT wifi links. 2.4 and 5g, on my phone. However, when I put in my wifi password, it states it id INCORRECT! I checked the spelling multiple times. Please help!!
