HT1976 iPhone 5 has suddenly stopped connecting to the internet away from home

My iPhone 5 has suddenly stopped connecting to the internet when away from home. It was fine last Wednesday, then on Thursday all I got was 'Safari is no longer connected to the internet'. I cannot use the Messaging, Find my Friends etc.
As far as I know I have not done anything to alter any settings, but I did change my password on Wednesday - which works, so I think that's OK.
Has anyone any idea what is happening?

My ipad has suddenly stopped connecting to the internet. The settings have not been changed. Why is this?

My ipad has suddenly stopped connecting to the intenet via my home wifi system. The settings have notbeen changed. why is this?

The first thing to try is to power down your modem and router for about 30 seconds, then repowering by plugging them back in.
Also, if that doesn't work, on your iPad you can try going into settings/safari/clear history/clear data and cookies.

IMac suddenly stopped connecting to the internet

So, I left the room for a while and let the screen saver come up, when I came back it wouldn't connect to the internet with any program (iChat, Safari, Firefox, and Thunderbird).
I connect via ethernet to FiOS but none of the other computers are having trouble connecting.
It's not a connection problem, thankfully. I connected my ethernet cable to a laptop and it connected perfectly.
I ran a diagnostics, however it was essentially useless. It told me that it could not connect to the internet or the server, and to check to make sure that the URL was typed correctly... No websites will load, though.
I did ping my mother's laptop (and my own computer) and it came back fine again, again and again...
In my limited opinion, it has to be some sort of software problem, but this being so all of a sudden bothers me. If I were on a PC I would think virus, but since it's a Mac, this is not likely at all.
Please give me some help and ideas, cause I have run out...
Thanks,
Mike.

I used to have the exact same problem, after I cleared my dns cache and renewed my DHCP license everything worked. Strange thing is that, somehow, someway, by some form of magic this problem stopped happening all together so I never had to continue issuing the command everytime. Could've been due to an update shrug
Type the command below in a terminal. Then renew your DHCP license in Network settings
-> sudo dscacheutil -flushcache

WRT120N Suddenly stopped connecting to the Internet (Modem)

Hi!
Well, I have a WRT120N Router for 11 months to now. I never had a problem with the Router, but since 2 days ago, It didnt connect to the internet.
My network is:
Internet > Cable Modem > WRT120N > Computers
As I said, the problem is that the Router doesnt has Internet Connection.
Things to take in consideration:
The Cable MODEM ISN'T the problem Because if i connect the modem directly to a computer, I have Internet connection without problems.
I Diconnected and Connected both Modem and Router in several ways and several times, and it doesnt work.
I also tryed clonning my PCs MAC address to the Router and it was the same.
The Router Indeed receives the External IP Address from the Modem, and also, it changes if i restart the modem (as my ISP IP is DHCP). But there is NO internet conection.
The Router had the 1.0.05 Firmware, and i upgraded to 1.0.06, and the problem persists.
Another thing to take in account is that if I turn off my modem and the I turn it On, sometimes, the router receives Internet connection, but in matter of Seconds (minutes as much), the internet connection falls.
This is NOT an ISP problem, because as I said, if I connect the Modem Directly to any PC, i have a perfectly normal Internet Connection, And also, I called my ISP and they Said me that there werent any problem on their network.
I have also tryed with the "Router Dianostics" (the Ping and Traceroute options that are in the Router's Webend and also, no conection. So its NOT a Cables problem.
So, im thinking that this could be a hardware related issue...
What do you think?

Hi
Well i belive the only thing which is left now is DNS.. Might be the DNS address that you are getting from the ISP is not working through the router.. You can try in putting a Global DNS address on the setup page of the router..
And if that does'nt resolve the issue.. It could be hardwire issue with the router itself.

Why has firefox stopped connecting to the internet

Hello,
One morning I was enjoying the internet. That after noon i clicked on firfox to check my email and i was not able to get on line. We checked and all the wifi gadgets were doing fine. my laptop is hardwired by ethernet to the hub so I checked that all out but the cord and connections are fine, plus windows gave my devices and internal conections an A+.
I have Windows 7 64. with two sata harddrives and two WD USB books. I back up to all of them with Casper backups. I booted with each and firefox was corupted in all of them. I was shocked. I tried system restore with no luck. My big mistake was deleting Internet explorer a few months back because I thought it was taking up space.
I wenton line with my laptop with which i am slowly writing this. I went through every off line fix I could find with no luck. I tried downloading firefox and eventualy IE and Chrome to a Flash key in my laptop so I could load firefox back into my Desk top. I have yet to find away to do that. I even found instructions on how to do that and I had a back andforth communication with an administrater on a tech forum. Everthing he suggested did not work.I was very polite but I havent heard back from him. I tried Portables No joy.
I am being wordy here to save people time who might think of the things I have already tried. In reality, I am at the poiInt where I will go ahead with a fresh windows system and try to salvage as much as I can. Unless, someone can explain to me a way out of this mess.
I would be forever grateful,
Angster

Can you start Firefox in <u>[[Safe Mode|Safe Mode]]</u> by holding down the Shift/Options key?
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window

My imac has just suddenly stopped connecting to the net

My mac just radomly stopped connecting to the internet last week and i cant get it to reconnect again. All the other devices in my house connect perfectly. i use an O2 home hub and have had no problems for a year with this so im guessing its the mac. my girlfriend recently bought a printer and plugged it in next to the mac but it isnt connected, is there any chance this could be blocking the wireless signal? thanks mike

Hi Mike...
Try turning off the router for about 5 minutes, then turn it back on then restart the Mac.
If the printer isn't setup for printing with the Mac, I doubt that's the problem.

HT1212 After working perfectly for two years my iTouch has suddenly stopped connecting to my Hub. I have tried everything I can think of to get it working again but to no avail. My desktop computer still works through the same hub

After working perfectly for two years my iTouch has suddenly stopped connecting to my Hub although my desktop computer still connects. I have tried everything I can think of, including suggestions off Google/You Tube but nothing makes any difference. Any ideas. Surely it is not fit for the scrap heap after two years, but is clearly no use as it is.

Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Droid Ultra has suddenly stopped charging from the wall plug-in

My Droid Ultra has suddenly stopped charging from the wall plug-in. I've tried every charger in the house. I've tried to plug it into a wall charger at work in case there may be an issue with my outlets at home, but it won't charge from a wall plug-in from any location. However it will chage if I plug it into the computer or my portable battery charger. Any ideas why it won't charge from a wall plug-in and how I may fix it?

Let's get your phone charged, chaseperil! You stated that you have tried every charger in your home. Have you tried the whole charger or just the cable? We want to make it is not the plug part of the charger. Are you using the charger that came in the box?

My iMac won't stay connected to the internet, even though all other computers in my house stay connected

My iMac won't stay connected to the internet, even though all other computers in my house stay connected, and its connection is set up the same way my fiance's macbook is (his macbook is about three years older than my iMac). Every time my computer goes into sleep mode and I come back (even if it's mere seconds after giving the black screen) I have no internet connection. I discovered a workaround for it some time ago, but now that is working less and less, and now my computer randomly disconnects WHILE I'm actively using the internet. Just a few minutes ago, the connection refused to come back until I restarted my computer, even though once again all other computers in the house were connected. The workaround I discovered before and which doesn't work as reliably now, is to click opne Airport at the top right of the screen, click "Open Network Preferences," then click "Assist me," then click "Diagnostics," and wait for everything to turn green again, signalling a connection.

Let's check the quality of your connection since signal strength alone does not insure a good connection. The "bars" that you see at the top of the iMac screen are there pretty much for show.
Hold down the option key on the iMac while you click on the Apple icon at the upper left corner of your screen and select System Profiler
Look down the list of items at the left of the window until you find the setting for Network, then click on AirPort.
In the window to the right, look for any listings of your wireless network name. You may possibly see two listings for the wireless network name.
We need for you to list the information that you see for Signal / Noise. These will be negative numbers. Post back with your findings and we will continue.
In the meantime, please move any cordless phones that you have or any other electronic devices that are near the iMac as far away as possible from the iMac.
If the iMac is located in a corner or an enclosed area, give it as much room as possible since the wireless antenna is on the back of the iMac and it needs to be able to "see" the room.
Anything that you can do to minimize the number of obstructions like walls or furniture etc between the iMac and the wireless router will help the cause as well.

We are on holiday in Mexico. Our iPad has no problem connecting to the Internet through a subscription WiFi network. But, both of our laptops can not with the same password. What can we try?

We are on holiday in Mexico. Our iPad2 has no problem connecting to the Internet through our hotel's subscription WiFi network. But, both of our macbookpros can not with the same password. What can we try?
We can join the network, but can not access the Internet. The password is correct. We have tried network assistant and diagnostics, restarting the laptops, re-joining the network. Our iPhone 4s also works all the time.
Same location. Signal strength is good.

Since I couldn't figure out a way to edit our original post, here's another potential clue.
Our laptops, when in System Preferences>Network, say "WiFi has the self-assigned IP address of XXXXXXXXX and will not be able to connect to the Internet".
Strangely, my six year old MBP running OS 10.6.8 accessed the Internet straight away, just by opening Safari to my home page. My wife's six month old MBP running OS 10.7.2 could not.

Firefox has suddenly stopped connecting on one of three user accounts on the same computer. That account still connects with Safari - but not Firefox. A clean-install has not solved the problem. Help?

Three user accounts on the same computer all link to a single copy of Firefox 3.6.8 - but one of them has suddenly lost its ability to use the program. Firefox opens in that account, but it cannot connect to the Internet. 'Done' appears at the lower left of a blank Firefox page [it's set to load a blank page initially], as though a page had finished downloading ... but Firefox does not actually generate any Internet activityx.
Previously, the Firefox connection for this account was smooth and reliable. I haven't added, upgraded or downloaded any new programs, nor made any other computer changes in recent weeks or months.
Puzzlingly - that same account still connects successfully to the Internet via Safari. And the other accounts on the same computer continue to use Firefox with no problem - including a test user-account that I set up today to help troubleshoot the problem. The blockage is restricted solely to Firefox with that one user account.
Following your Support page instructions, I did a clean-install of Firefox 3.6.8, removing both the existing Firefox 3.6.8 and the Library/Application Support/Firefox folder. Going the extra mile, I checked all accounts to be certain that no Firefox folders remained in any of them - then emptied the Trash and restarted before installing a freshly downloaded 3.6.8. But blimey - the blockage still persists for that one user account.
Firefox shows no visible cookies that might influence the connection. [It's set to delete all cookies upon closing anyway.] And I see no obvious instructions in Mac's firewall or any software program to refuse access to Firefox. The computer is stand-alone, not networked. And in any case, Firefox works just fine in the two other user accounts.
Deleting the hobbled user account is not feasible. So what is causing this roadblock? Did I miss a step in the clean-install? How can that account resume using Firefox?
Thanks in advance for your advice.

If files already have been downloaded then remove the files in the updates and updates\0 folder.
You can also delete active-update.xml and possibly updates.xml (stores the update history).
