IOS devices not connecting to Internet while MacBooks does

Hi,
I'm in the process of closing my Verizon Internet and testing a Comcast service. Before unplugging my Time Capsule from the Verizon adsl modem I made sure that all worked ok with the Comcast cable connection. My MacBook worked right away through Ethernet and so it did through wifi when plugging the TC to the Comcast modem. The problem came on our iOS devices, 2 iPhones and 2 iPads, as they did recognize the network but could not connect to Internet.
I called Comcast customer care but as expected they wash their hands as I have Internet on my computer...
Any advise? Is there something else I need to activate?
Thanks
Pablo

Change the names to short no spaces no special characters. For wireless and the TC.
Lock the wireless to on a/n - b/g
Then fix the channel for 2.4ghz.. 1, 6, 11
Those measures usually get the iphone working .. ipad should work also.

Updating iOS message not connected to Internet

I am trying to update my iOS, message states I am not connected to Internet, yet I am.

the best way to update your dvices is to plug it into your computer with itunes up and it will prompted you to update it.

IOS devices not connecting

I just set up an airport express, first version, and it is working fine with my macbook pro but won't connect to my iPhone 4S or my iPad (1). When I put in the password on both devices it just spins. The airport setup utility (6.1) sees them and gives me strong connection info.
Any idea why the iOS devices aren't connecting?

Suggest that you temporarily turn off the wireless security on the Express and see if the mobile devices will connect that way.
If they will, then you know that they can connect using the wireless signal....so there is a security issue at play. Try using WPA/WPA2 Personal on the AirPort Express for wireless security if you have not already done that.
If the mobile devices will not connect when the network is using no security, then I am out of ideas....other than completely restoring the mobile devices.
I would not do this until I received confirmation from the iPhone or iPad experts in those respective support areas. They may have some additional ideas for you regarding the mobile devices. Good luck.

TS4062 My iOS devices not connecting to iTunes

I have an iPhone 5 with iOS 7.1, iPod touch 4 with iOS 6.1.6 and first generation of iPad with iOS 5.1.1. All are fully updated. I keep this up to date at all times. I am using iTunes 11.1.5.5. I have had nothing but problems with iTunes connecting to them via wifi. I have tried over and over to get them working as they SHOULD for a few years now. I have gotten them to all connect a few times but then they will stop connecting again. I have tried over and over to remedy this and to be honest I'm sick of it. I am about to stop using iOS devices due to this. Anyone have any ideas how to remedy this?

I'll assume NAT is in use here.
Are your iOS devices using the same DHCP server, same network, same DNS server, and the same settings as your OS X systems? Do you have references to any other DNS servers in use here, or are all your systems using only your own local DNS server, with no references to other ISP or Google or off-network DNS servers?
Do your iOS devices have the necessary certificates loaded?   (Loading the certificates first, then the entitlements, is typical.)
Using .local is not something you want to tangle with here.
I'm going to assume you're obfuscating your domain here, as it's not likely you're using the (real and registered) domain "mydomain.net" here.   I'll also assume your local DNS is not using .local or .arpa as the domain name. (If you're obfuscating, please consider using example.com, example.org or example.net, as these are reserved for this and similar uses.)

Safari says not connected to internet- System Prefs does...

OK, I'm not extremely computer savvy, but I'm not totally ignorant either. But I have a network connection problem that I have absolutely no idea what's going on. I have a black MacBook Pro, and am running 10.4.11. I have an airport express at home, and never had any access/connection trouble. Where I work (a university), there is an open network we can access, but for some reason, I cannnot. My airport status indicator shows full strength, and systems prefs gives me the connection is A-OK message with the green light, saying I'm connected to this network, but when I open Safari (or Firefox), it tells me I am not connected to the internet. Another interesting thing is when I open itunes in this situation, it finds shared music libraries on the network, but it will not connect to them. This is the only network I have ever used where this is happening. Also, other people seem to be able to access this network with no trouble with Powerbook G4s. Does anyone have similar problems or any ideas at all on this one?

My guess is that you're not authenticated on the network and, for that, you should talk to the sysops there. Most universities have "open" networks that still require authentication, meaning they're open to the university users but not to everyone.

UPDATE FIREFOX , DOWNLOADS BUT WILL NOT CONNECT TO INTERNET, OLD ONE DOES. WORKING ON MAC WITH LEPOARD

"Not connected to Internet" error message

Hi Guys,
Safari keeps throwing me "you are not connected to the internet" error messages. I'm running 10.5.1 and I chose the "upgrade" option.
The errors are displayed randomly on sites and if I get the error upon visiting a site, I usually have to wait about a half hour before i reload the site and it works normally. This is happening to approximately 20% of the sites I visit. I can view the same exact site in Firefox, but I also get the same error in Mail, Aperture (flickr export) and twitterific.
If a site (like Flickr) pulls resources from multiple urls, even though the initial site loads, the resources may not. For instance, loading Flickr, the page may load, but since the images are on a separate server (or multiple separate servers), the images may not load or may load randomly.
I tested failing urls in Network Utility > Traceroute and urls that throw the error message get an "unknown host" message. I assume this bug has to do with Mac OS X as opposed to my ISP. and that web kit is probably the culprit, as I'm having this problem on apps that use web kit to access the internet (firefox does not).
This error is also happening on my powerbook G4 that was upgraded to 10.5 as well.
anyone else having this error? i don't seem to see anything in the forums.

I am having this IDENTICAL problem. My ISP is Cox Communications and at first I thought the problem was DNS related. It certainly appears to be, but I went and dusted off my old Windows laptop and internet access works very well, fast and snappy. Since upgrading to Leopard on my Mac Pro and MacBook Pro (oh yes, I was stupid to upgrade both at the same time) I have been so frustrated with this problem. Safari will tell me I'm "Not connected to Internet" while Firefox will happily load the same page. Mail will tell me it can't connect to the smtp server while tcpdump shows it not even trying. A half hour later it starts to work temporarily. I have tried using different DNS servers but it doesn't make a difference. The problem is definitely Apple Safari/Mail. Boo!
Please someone at Apple fix this problem quickly. This is extremely frustrating.

TS1398 My ipad says it is connected to WiFi, which is workingly perfectly for several other devices, will not connect to internet. It keeps giving the message 'Cannot Connect' or error has occurred or just blink off site or icon?

My ipad says it is connected to WiFi, which is workingly perfectly for several other devices, will not connect to internet. It keeps giving the message 'Cannot Connect' or error has occurred or just blink off site or icon?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

HT4623 I can't update my iphone 4s iOS 6.1.2, Message saying I'm not connected to internet but I am, why?

Every time I'm trying to update my 4s with iOS 6.1.2, keeps showing message that I'm not connect to Internet, but I am, anybody experiencing the same issue???? Help!

I was able to update my iPhone 4S to 6.1.1, BUT :: I could not update to 6.1.1. from my iPhone. I received the same message as everyone else saying that my iPhone was not connected to the Internet, which is was. (I was able to access my mail etc. via Internet.)
Instead I connected my iPhone to my computer via ITunes via the cable. I then downloaded the software on my computer and updated the iPhone from the computer. While I was downloading the software on to my computer, which is only connected to the Internet via ethernet, the same message as above appeared on my iPhone about not being connected to the Internet. I pressed cancel. The software continured to download on to the computer and then on the iPhone.

You can try these things and see if it helps.
Tap Settings, then tap Safari on the left side. Then on the right side - tap clear history, clear cookies, clear cache. Clear all three. Reboot your iPad. Hold down on the sleep button at the top until the red slider appears and slide to power off. Then hold down on the sleep button until the Apple logo appears and the iPad will restart. Launch Safari and see if helped.
If that doesn't help, try this. Tap Settings, then tap General on the left side, then scroll down on the right side and tap Reset, then tap Reset Network Settings at the top. Reboot your iPad as described above. Launch Safari and log on to the Internet. You may have to enter your network password again when you reset Network Settings.
Renew the Lease in WiFi by going to Settings>WiFi>Network Name>Renew Lease. Reboot your iPad and try Safari again.
