Tapo D235 dooebell which is only a couple of weeks old is always going offline and telling me it can't communicate at the moment. It has a wifi signal speed of 31mps and -47 RSSI quality. it is situated less than a metre from the signal sender and the signal only has to go through one pane of glass. Does this indicate there is a problem with the unit (bought direct from manufacturer) or is there something I can do to get it to stay connected? At the moment it seems to have a mind of its own(AI maybe) and only connects when it wants to. Any help would be appreceiated before I give up and box it up for return, thank you in advance.

As a add on to this post, I also get a message saying 'Network unstable' and I can see above the live stream picture(when I can get one) the KB's figure constantly changing, ranging from 0 to 375Kb's. Not sure what this means if anything or what to do about it as my wifi is rock solid everwhere I test it including infront of the doorbell.
