Discord - Special characters not allowed in Wyze Mesh Router Pro SSID or password
It is expected that SSID and passwords with special characters should work unless that special character is an apostrophe. The block on apostrophes is by design. However, we saw a report that the router behaved incorrectly when dealing with this case so we want to look into what happened there. If your router crashed or otherwise stopped responding when special characters were used, please make sure that you’re using firmware 1.0.0.73 or later. If you are on updated firmware, please then send in a log using these instructions:
Recreate the issue. Then in the Wyze app, go to Account > Wyze Support > Submit a Log. Select your device from the dropdown menu. Then fill in the description box with the date, time, and time zone of the most recent time you noticed this issue and a description of what’s happening. Make sure the Send Logs option is selected and then submit your log. When you have the log number, please post it here as a reply to me so I can get it to the right folks.
