Loosing Wi-Fi connection on and off for 3 weeks

[Sarkin]

We keep loosing internet connection across all devices. Has been happening on & off for 3 weeks now. PC, mobile and games devices.

Sky broadband checker says there's an issue but works through the stages and says there's nothing wrong in the area, or the router or connecting so don't know what's wrong.

For last 3 weeks been loading wifi sky says no issue but I work from home this is effecting my job.

I work from home too as a call centre operator and it keeps disconnecting my internet calls whilst I'm trying to help other customers. Hoping this chat helps - I can't even connect to wi-Fi to be able to write these messages.
