A confusing issue

I have been using and Xfinity hotspot for my wireless service for over a ye
ar now without issues.  Very strong signal and great speed.  I have my HP l
aptop, an Ipad mini and my iphone.  All connected without problems.  ( I ne
ver understood how I could have that great of service when the nearest hots
pot is 1/2 mile away).

Anyway, there was a storm last week and many people lost power and internet
.  I had no interruptions where I live but I lost internet for a short peri
od of time.  Then it came back, but only on my laptop.  My Apple devices ju
st say no internet service on the xfinity network.  I can take these device
s elsewhere and connect on a hotspot or a home network.  Just not in my apa
rtment.

The Xfinity "Hot Spot Team" was useless, they couldn't tell me anything.  A
pple was puzzled as well.  It just doesn't make sense.  

Can anyone here figure this out?  It's driving me nuts.

Thanks in advance!

Looks like Xfinity internet service is down in various cities:

At this time, it's working in Santa Cruz CA at my palatial office, but
you might not be so lucky.

You might have tried this but on the devices that will not connect, go  
into them and tell them to totally forget the Xfinity WiFi ever existed,  
reboot them, and then let them try and relearn the Xfinity WiFi  
settings.  Possibly they were connecting to one hotspot and now are  
connecting to another one with the same "name" or SSID but because the  
two of them have different MAC address values your devices are getting  
confused.

If you are not already using a WiFi searching program on your laptop it  
might be worth giving the Acrylic WiFi program a try.

It can be found at https://www.acrylicwifi.com/en/ and is free to use  
for home users.  It will show you all the WiFi transmitters in your  
local area, even if they all have the same SSID.  One nice thing is that  
this program gives you the SSID as well as the MAC address of the  
transmitter.  Not knowing Apple products I wonder if it tells you the  
MAC address of the transmitter it is trying to use.

Re: A confusing issue
Thanks for responding Jeff.  I'm not quite sure I understood everything you
 said but I'll try responding as intelligently as I can.

I've never seen more that one xfinitywifi on my list of networks either uns
ecured or password required.  I don't think any of my neighbors has xfinity
 as I never see it.

I have done the battery thing on my computer and have even gone into the Xf
inity account page and removed my device from the list to see if that would
 do anything.  No.

I've tried to "forget" the wifi network on the ipad and iphone to no avail.
  There is another unsecured network listed and she's a couple of buildings
 down from me and both devices can connect but the signal is extremely weak
 and drops off.  

I'm ordering internet service for my apartment now because I watch tv onlin
e and I bought the Ipad to give my computer a break.  Where I am in New Ham
pshire, I'm lucky to get a cell phone signal where I live.  It was a nice b
reak to use the hotspot for free and have it work so well.  I don't suppose
 I'll ever find out where it is.  It was like it was right here in my apt b
ecause if I went outside with my phone the signal would weaken.  Mysterious
.  It's really funny that the "hot spot team" doesn't know a thing.

If you can think of anything else, please let me know.  It's maddening.

I was just watching an old Sherlock Holmes movie.  Might as well use
his methods.

xfinitywifi is the SSID used by ALL Comcast hot spots.  Looking at the
app "Wifi Analyzer" on my Android smartphone, I see 5 access points
named xfinitywifi.  You probably had a similar situation before the
storm.  One of those was fairly close and the one you were using.
However, after the storm, the closest xfinitywifi hot spot dropped off
the air for some currently unknown reason.  So, now you are connecting
to one of the other xfinitywifi hot spots, which may or may not have
connectivity after the storm.  Or, whatever you have configured on
your unspecified Apple equipment might have been specific to the
original Comcast gateway that you were originally using.  You might
try rebooting EVERYTHING that you're using and see if that helps. That
include temporarily removing the battery and battery charger from your
HP laptop and letting everything discharge (about 30 seconds).

Another complication is that the Comcast gateway that you're
connecting to was hung or mangled by a power glitch.  There are some
models, such as those made by Technicolor, that tend to have that
problem.  If the gateway has a backup battery installed, it will need
to be reset with a paper clip, or by Comcast tech support.  Cycling
the AC power does nothing.  It may take a while for your neighbor(s)
to notice.  If you know which neighbors xfinitywifi system you're
using, you might try banging on their door and ask them to reset their
gateway.

It might also be that your wireless client in your computer is still
trying to connect to one xfinitywifi hot spot, while the other
computer is trying to connect to a different xfinitywifi hot spot.
Check the MAC addresses of the hot spots in the connection manager to
be sure.  If this is the problem, try to set the target MAC address to
the xfinitywifi hot spot that still works.

...when you have eliminated the impossible, whatever remains, however
improbable, must be the truth.
