Recent drop in WiFi speeds

[Du2]

The wifi has recently dropped in speeds with typical speeds just 1 floor (approx 5m away) from router having speeds of 20download and 15upload. This has been tested across multiple devices and consistently causes work calls to drop out every 5-10 minutes. A couple of the times I have tested speeds have been as low as 2. This is a recent issue

@Du2 Testing the wireless wi-fi signal is everything else that is wireless turned off and you only have the Hub and that device in play?

No as our broadband plan says up to 10 devices should give us a connection of at least 90

@Du2 The info from the sky Help below, see if it does anything for you, hard to say as no information is supplied, you may just be having a sky Hub issue or something on your wireless wi-fi going bad!
