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.

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.

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 imac has suddenly stopped connecting to the internet

When I restart mac it connects to the internet through my personal wifi network for a couple of mins before losing connections it then cannot find any wifi networks all other devices are working fine and do not have any connection issues. Any advice please

Try posting in the iMac forum. This is the iPod touch forum.

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

My ipad suddenly stopped connecting to the wifi network. My lap top still does however

My iPad was working fine with the wifi at my house but suddenly stopped working today. My laptop still connects just fine but I can no longer get my iPad to connect. Any suggestions?

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.

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 my ipad stopped connecting to the server?

About two days ago my ipad stooed connecting to the web. All the apps and browser pages oome back saying they cannot connect to the server. However I have an phone and a pc that are both connecting to the web fine through the same router. The ipad says it is connected to the router no prob. What next?

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 drooping 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

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

The device woked fine for over a month until today
All other devices in my home are working just fine

A) Check firewall settings... BOTH programs are cleared for Bit Passage
B) Check Anti-Virus.... Anti-Virus Disabled.. UNINSTALLED and Registry Cleaned.. still has the problem persisting..
C) Deleted and Reinstalled Thunderbird & Firefox Working Directories (without deleting User Profiles)... Problem still persisting..
D) Created NEW Profile with Profile Mgr in Firefox.. no go...
E) RAN WHOLE System VIRAL/MALWARE Check... .. No infections..

Thank you, for that. To be sure, I tried your suggestion, and selected "System Proxy" as the choice, for Thunderbird and Firefox. Rebooted, and looked at the outcome.. NO Joy.. :-(
I believe that I shall send the output of the Error Log in my next post. Perhaps someone can point me in the right direction after looking at the Error.log.
Thank you...Toad Hall. If you think of something else to try, I am ALL ears.. I shall keep trying..

How to connect to the net - high speed

Hi there, Im writing for a friend of mine who has a iMac... he has his highspeed cable plugged into his iMac, however the net does not work.... on my macbook once I plug in my cable the internet works right away for me.... so Im wondering what he has to do / get for his net to work.... He has a PC that connects to the net via a modem.... however his iMac is downstairs in the basement....
ne suggestions? Thanks a bunch!

Usually the modem needs to be reset. It stores information about your computer that sometimes needs to be reset.
Have him power down the computer, then unplug the power to the modem.
Wait for a minute, then plug the modem back in and wait for it to initialize itself. Then power up the computer.
If that doesn't work, have him call his internet provider.
They can determine if there is anything wrong with the line or the modem.

Imac and Macbook Pro suddenly stopped connecting to my wireless network

I am having the strangest problem. I've had a linksys router for years and my network has worked fine. I have a 2008 iMac, a new Mac Book Pro, Xbox 360, and a PS3 connected to it. Yesterday, the Apple products stopped connecting to the linksys, however the Xbox and PS3 connected fine. I thought it was my router being the problem so I went to Apple Store and bought an airport express to just set that up as my primary router. I could not set it up the normal way wirelessly as neither my iMac or MBP would pick it up via the Airport Utility tool. I had to hardwire it to my iMac to get it set up. It seemed to not be working however the green light did eventually come on. My xbox connected to it fine, however the iMac and MBP would not connect. Both did end up connecting but only for a short time and now neither can find the Airport Express. Does anyone have any suggestions as to what my problem is? It just doesnt make sense that both mac computers stopped picking up the linksys at the same time, and neither will really pick up the Airport express either. I'm just so distraught over this because I had everything working fine such as sharing files, wireless printer, Apple TV, etc.

Hi there, I have exactly the same problem, one year with imac and a few months ago my wireless network disconnected and kept disconnecting and connecting on and off, it's not the Internet because laptop and other aps are ok
Today I tried contacting Virginmedia to see if they could help and they told they are not trained for mac! Anyway they suggested to try to use the "renew DHCP lease" button in the TCP/IP page in network settings and it seems it is working better now, lets see if it lasts...

Imac suddenly stopped connecting to network

sorry if this topic already exists somewhere. i've been searching these forums for an hour and can't find any useful help on the subject.
we bought our first mac almost 1.5 yrs ago. this beautiful 27" imac worked fine for 1 year and then suddenly stopped connecting to our wireless network. distance to the wireless router isn't an issue. doesn't matter where i move it to in the house, it sees the network, but won't connect anymore. 6 other laptops/video game consoles/pc's all continue to connect w/o a problem. this happened once approx 3 months ago and i figured our old router had kicked the bucket, so i bought a new router and it worked fine for several months and now it's happening again.
i've gone thru all the preliminary steps of unplugging the modem, the router, the imac, and renewing the dhcp but nothing helps. it will work fine if i wire it directly to the router, but i don't want to run a 75ft ethernet cable thru the house.
i'm so frustrated with this supposedly wonderful imac! can anyone help me?

Here's something to think about... I know my AT&T DSL Cable Modem will only allow a certain number of connections. A few years ago that might not have been an issue, but now with wi-fi cells, gaming systems with netflix, other laptops/ipads, you might be exceeding that limit. It could be they are all connected and you don't have a spot on the router.
This might be elementary, but thought I'd throw that out there.

HT1430 My iPad isn't getting connection to internet. It just suddenly stopped! It says it is connected to WiFi but it just keeps spinning and nothing will come up. Have tried rebooting my router and iPad (my other computer is connected just fine).

Try turning WiFi off on the iPad, then reset it again, turn WiFi on again and join your network again if necessary. Or go to Settings>WiFi>Your network name>Forget this network. Reset your iPad and then join your network again. Or - settings>General>Reset>Reset network settings. Reset the iPad, then try to join your network again.

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.
