I know you mention you've tried all the tips, but you can you just double check you've definitely tried the steps in the following help page to disable pings, as this usually solves connection problems
However, your post suggests that your box can't see your wifi network at all. In which case it's possible the box is out of range or can't see the wifi network for some reason. If you are setting it up in a room far away from the router, try moving it to a closer room to see if that helps. Also, make sure the box isn't sat too close to the router (give it a couple of feet distance at least) and place the box so that it has empty space around it (eg not tucked behind the TV or in a closed TV cabinet).
Also, check that your router isn't set up for a 5GHz only wifi network, as the White box can't see 5GHz wifi networks, only 2.4GHz.
Similarly, if your router is set up to not broadcast the SSID (the name of your wifi network) then it wouldn't show up on the setup page and you'll need to select the option to enter it manually.
Finally, you might try setting up the guest network on your hub if your router has this facility (check documentation) - make it a 2.4GHz network with a different SSID name to your main wifi, e.g nowbox and try connecting your NOW TV Box to that guest network. Make sure you choose WPA2 for the encryption method and choose a strong password.
Are you with Virgin? If so the guest network trick often seems to work for some reason. You are basically creating a separate wireless network that you will only connect your NOW TV box to. If you type Virgin guest network into Google you will get instructions.
Otherwise if you reply with details of your ISP and router model and a quick list of what you've tried already then a member of the NOW TV Team (or another member with more experience) will pick up your post in due course.
Welcome to the forum.
Start off by looking at the following help page, and if you still have problems post back with details of what you've tried, which ISP you are with and what is still happening
Thanks for posting.
Also please ensure you're not trying to connect via an BT hotspot or a similar open network as the box will not be able to connect to this.
