I use an xfinity wifi hotspot to enjoy the Internet. It's worked fine for many months. I use the same hotspot on my iPad and my Mac laptop. I awoke today and the Internet wasn't working on any device, but then it began working again on all devices except my PC. It's been tens of hours now and still I can't connect to the Internet on my PC.

The signal strength is great, but when I connect, it just says "No internet, open" and I seethe with indignation. I disconnected, reconnected, refreshed my IP in the command prompt, and WHY DOESNT IT WORK?!!?!?!?

did it simply start working on other devices with no intervention on your behalf?

What OS are you running? Have you tried 'forgetting' the network (deleting any saved settings for it) and rejoining it?

Right--the other devices just spontaneously started working again fairly quickly.

I'm running Windows 10, and yes, I've tried disconnecting, forgetting the network, resetting my drivers and adapters. Nothing works. Again, I can connect to it, but it says "no internet" when I do, despite this same network providing Internet on other devices.

Does ipconfig from the command line show you getting a valid address?

Are you able to test your PC's connectivity with another hotspot? Maybe on your phone or similar?

ipconfig gives me a valid address. Unfortunately I don't have any other wifi sources I can test the computer on, but I'm quite confident it isn't the computer's fault, since now the Mac laptop and the ipad can no longer get internet from the xfinitywifi source, so I'm down to my last remaining device--an old iMac. Why this public wifi network keeps pruning off my devices, I do not know. But I fear it's only a matter of time before the iMac is also killed, and I'm back to the stone age. I called Comcast (who owns Xfinity), but they weren't helpful.

as far as i knew (could definitely be wrong), comcast only offered access to the xfinity wifi hotspots if you are a comcast home internet customer. once you connect to the hotspot, doesn't it make you sign in with your comcast account?

i believe comcast limits the number of simultaneous devices that can connect to one xfinity wifi hotspot created on the device in each of their customer's homes so that it doesn't slow down that customer's service. if you're in a heavily populated area and connecting to the xfinity wifi hotspot on a neighbor's home router, it could be that lots of people are connecting and so more devices are denied.

Five devices, I think.

Xfinity just launched their mobile service and their devices are set by default to connect to an Xfinity hotspot if within range. It is hard to imagine, but it is possible that others' cell phones have recently begun latching onto that same hotspot and tying it up.

If this is not your Comcast connection then yeah don't expect a neighbor to let you siphon internet.

If this is your Comcast connection, you should just connect to the regular 2.4 or 5 band instead of the xfinitywifi default, if you haven't changed it yourself the ssid and passphrase are printed on the Comcast modem all-in-one

I'm also a bit confused about why you'd use the xfinitywifi inside your own house if you're an xfinity customer. Can you explain your setup a bit more? What service of theirs are you paying for currently, for example?

I'm beginning to think someone changed their Xfinity password.

I have a Comcast username and password, but this isn't my house. My house is in another state, but my login info has worked at this hotspot for months. So I don't have a personal modem I can use. I don't actually know where the source of the hotspot is--some resident's equipment that also broadcasts a signal for other Comcast customers to use, or a dedicated hub on a telephone pole. But it sucks that I can't use my computer on it, but I can use my crappy iMac.

Also relevant, now the laptop and iPad are working again, but still the PC (which is most important) gets no internet (again, from the same source that the other devices are using, and the same source that the PC had been getting internet from for months, and that it is able to connect to).

My point is you don't have control or access to the equipment you are relying on for internet, nor the person. They may have noticed a drop in their performance from you siphoning from their radio bands since you would be dropping packets due to distance and impedance. As simple troubleshooting they may have moved the position of their unit to increase performance or since those units are low quality to begin with, it simply may be going bad.

Unless you want to go knocking on your neighbors doors to ask if they will reboot it and put it in the nearest window to you for line of sight (lol at that conversation) then get your own internet. If the internet is important for your daily function then don't be surprised that it can go away if you put yourself in an unstable position to begin with.

Also, look at ics through the iMac if you want to ignore the above advice

OP I had this same problem. i was at my grandmas house for a few months and was using an xfinity hotspot no problem for a couple months then one day i got a caution signal on the wifi bars and it said "no internet access". I called comcast a few times and they had no idea what i was talking about. talked to tech support and everything. it was never resolved and i just ended up getting comcast for that house. (i had comcast at my house and was using those credentials to connect to the hot spot).

so idk what to tell ya.

Pop the zip code of your current location into this Xfinity hotspot locator and you may at least get an idea of the location of the nearest hotspot(s). You may have to scroll down on the screen to see the map.

Something seems very wonky here, but, then again, it is Comcast you are dealing with.

According to that map, there are a couple hot spots right near me. It's bizarre that it works sometimes for my Mac devices, in an unpredictable pattern, and on some even while it is not on others, and as far as I've experienced, it never works on my PC, but I always have full bars and can connect on my PC; it's just that it gives me "no internet." I realize I'm kind of repeating myself, but I feel gadgetguru at least doesn't understand the problem.

I tried manually entering the DNS that my iPad was using while connected into my PC's IPv4's options, but that did nothing. I feel I'm in over my depth, but it also seems that anyone who has encountered this problem (in threads I've found in other forums) hasn't been able to provide a solution that works for me either. I am not hopeful.

i don't really know what xfinity is

but

next time pc is able to connect (no internet ) try to ping your mac devices , that will tell you if you at least have connectivity locally.

Also go to network sharing centre - change adaptor settings- right click adaptor- scroll to IPv4 clicktil blue then properties. - then obtain IP address automatically+DNS.

Does this map tell you distance/range from the wifi hotspot?

If you could upload screenshots of IPCONFIG (PC) and IFCONFIG for mac devices would be useful to see.

It's a cable and Internet company

All packets fail.

That's the default setting. It still doesn't work.

It's close enough. Signal strength is great.

It just says I'm disconnected from Ethernet (which is true) and local area connection, and then it gives me my IPv6 link and IPv4 IP and my subnet mask, all of which look fine. Everything looks fine for my Mac devices as well. I don't know what you would hope to glean from either. If you have some plan, I'm all ears (eyes).

when you goto network and sharing centre (the default settngs bit) also click at top alternative config - make sure nothing is there also.

id like to see the outputs of the Ipconfig /all , of both the windows and apple devices it makes it easier to troubleshoot,what you think might look ok might or might not be.

You could try tracert or pathping to see where your ping is failing (ping your apple devices from your PC make sure all are turned on)
tracert 8.8.8.8

pathping 8.8.8.8

ping 127.0.0.1

i was thinking at first the owner may have mac address blocked you, but if you was then you wouldn't get an valid ip address.



Also do you a lot of streaming or downloading on it? maybe a fair usage policy or something. But if you certain everything is ok on your end then you could reset. Try temporarily turning off firewall and AV first and check connection. *turn back on*



reset:
https://support.microsoft.com/en-ie/...nection-issues

then

Command Prompt. Type “netsh winsock reset” and then hit the Enter key on your keyboard , you should see a completed successfully message. Restart PC.

You mention you're getting a valid IP address when you connect via PC, what address, DNS, and default gateway are you getting? And your PC is set to DHCP?

Here's the info if you aren't familiar with xfinity hotspots. Basically, anyone who signs up and rents a modem from Comcast will sometimes have the newer units that broadcast a guest network called xfinitywifi which is on a separate subnet and authenticates with your myxfinity credentials provided you are paying for xfinity elsewhere with a plan of at least 25MB.

I don't believe they meant for this to be a long term and multidevice connection, it's purpose is for example, while you're in a doctors waiting room and hey happen to have Comcast you can get on wifi without asking for a password. Our guy here is trying to use this in a permanent fashion which is not its intended use, now he is having problems.

Except that Xfinity has now gone into the cellular business, piggy-backing off Verizon's network. They require customers to buy their phones from them because they are programmed to connect to Xfinity wifi hotspots when possible in order to keep Xfinity's fees to Verizon at a minimum. Since Xfinity offers unlimited talk/text and an optional unlimited data-plan, it seems they are prepared for some fairly heavy usage of those hotspots they have embedded nation-wide.

It inexplicably has started working again on my PC, and all other devices work also, as of about 14 hours ago. My IP now is definitely different from what it was over the past few days.

And maybe the hotspots aren't intended for long-term use, but that doesn't give a satisfying solution to the problem that the hotspot(s) I've been using worked just fine for a few months, then worked intermittently on my Mac devices and not at all on my PC for a few days, and now seem(s) to be working fine. I don't know if I can gather any data now to help in troubleshooting should things stop working again, so I'll just continue to pray that my internet continues.

I use the wifi at the local McDonalds. It's worked fine for ages and suddenly about 2 weeks ago it's become very unreliable. When it's down my tablet wifi says No Internet Open. It was down 4 days the first time, then 2, then 1 or 2 each time after. Overall it's been off about 8 days. And each time the McD staff say they have to wait for a Bell wifi tech to fix it. I think that's crap. Would a tech show up 7-8 times to do the same repair? I think he would have realized fairly quickly that his "fixes" were not solving the problem?. Is McD even contacting Bell?

Sounds like an issue with your Big MAC address.
