to see if there are any other t/s steps they can help you with or determining if you have to send your console in for repairs.

storm may have glitched the xbox , I would try a factory reset before I called about getting it repaired.....

Since you have mentioned that your Xbox one is not seeing any wireless networks at all, but other devices can, it may need a repair, but since your Xbox is 6 months old, it may still be under warranty. It is possible that the storm you mentioned may have
damaged the network card in your Xbox One.

You could try this troubleshooter:

"My Xbox One can’t see my wireless network".

If this doesn't help, I would schedule a repair.

You can do that from your Microsoft account page by doing the following:

1. Go to https://account.microsoft.com/devices
   
2. Look for your Xbox One
3. Click "Schedule a repair"

Wireless? I'd check the channel in use if its your router or contact Comcast for their High Speed Networking support, they can troubleshoot without cost if your using a Comcast provided router. Chan 11 seems to work well in most cases. If wired again contact
Comcast support.
