I've had NOW TV broadband for a couple of years without problems. In the past month or so we keep getting a lot of dropouts with wifi. Devices like ipads and iphones which have previously connected without a problem fail to connect, get an error after connecting saying there is no internet, get an error saying they just can't connect to that network, or get an error that the password is incorrect (even though it hasn't changed). Laptops fail as well and using the error tracking on them gets "The DNS server isn't responding".
The router lights are fine and an Ethernet connection continues to work fine, it's only wifi connected devices that are affected.
A reboot of the router usually fixes it for a while, then the dropouts for wifi devices start happening again. We end up having to use 4G a lot of the time on phones to get a stable connection (which isn't good for data package use).
Any ideas of what could be happening or ways to fix it? We have the NOWTVHub Two and one Netgear extender. Switching between the two networks helps sometimes, the Ext usually says full signal but is often pretty rubbish (especially in the evenings?) and it's better to use the weaker main network for a while but when it fails, both wifi networks fail, even with devices right next to the router.
