iplay 50 unstable wifi

Hi
I just received my new iplay 50.
It is a nice tablet. but I have a problem with unstable wifi.
Regularly, bandwidth goes very low, latency raises to multiple seconds (ping to my local router).
When I switch off/on wifi, it works again.
It is a real problem for watching movies, which is the main usage for this tablet.
Of course, wifi works well on my phone.
Should I replace the tablet?

I do have the very same issue..wlan is connected but it does not seem to load anything…EG videos wont start, webpages wont load…takes forever. On other devices with the same wlan no issues at all.

Just registered to write this.

The id**ts have designer it so the tablet case acts as a shield.

Open the tablet up and replace the antenna named “WCN ant” with a cheap one from Amazon or similar. Make a small hole in the chassi and mount the antenna outside and it will work. Mine went from 0.25mbit/s to over 50.

Mind that if you stick the antenna on the back the antenna becomes directional and the back must face the access point.
