Internet Drops out most weekdays between 13.00 - 14.00
Almost every working day my internet drops out completely for a period of time (can be up to an hour) between 13.00 and 14.00. It's always between those times, I work from home and my boss is getting cross about it. The engineer has been out and checked the hub (said it's fine) and the cable to the house has been replaced. If I use my phone (i.e. 4G) to run the service status app it says there is nothing wrong and to check the wifi strength, but the devices can't find a network even if sitting right next to the hub. Rebooting the hub sometimes resolves this, otherwise I end up waiting till the network comes back of its own accord.
Any ideas? And why always at the same time of day? As it's an intermittent problem, unless an engineer actually sees it during an outage he's going to say there's nothing wrong!
