Over the last few weeks my home wifi has constantly been disconnecting from all wireless devices e.g. mobile phone, tablet, laptop. I get different messages on different devices e.g. mobile phone disconnects and the wifi is not visible, tablet says you need to enter password but when you do it says its incorrect, laptops just says unable to connect to network. Devices connected by ethernet e.g. PC and electricity circuit via plug in adapter e.g. smart TV seem unaffected by this issue. The problem can be resolved temporarily by re-starting the router but as it now only lasts around half an hour before disconnecting again this is unworkable.
