Won't connect to email servers when switching networks!

I get spontaneous "Wrong User name and password" error messages when nothing has changed and I'm in the exact same spot. It just suddenly appears.
WORST OF ALL, When I switch from Wifi To Edge or vice versa, the iphone just hangs at "connecting to server" when checking email. Have to do a restart for it to check in to the mothership and get new mail. And even then, it's not 100 percent effective.
Many times I get mail headers but it won't download the message itself. Very frustrating. any news or thoughts?

Hey Tommy,
Is this a POP email account that is getting locked? It may be pop locked if two email clients are connecting to the server at the same time. This article: http://docs.info.apple.com/article.html?artnum=307009 provides more detailed information.
Also, if the Mail application appears to be stuck at checking mail you can force quit the application. Just hold down the home button for about 7 seconds. http://support.apple.com/kb/TS2032

BB Curve 9300 won't connect to email servers

Hi all please bear with me as I try to explain this!
I have a BB Curve 9300 on PAYG with Orange. It has always worked fine and emails for all email accounts always came through.
Then yesterday Orange tried to take the £5 for the BB services but I didn't have enough credit so obviously it all ended. I topped up today and they have taken the money. However my emails are not updating/downloading.
I have checked and I have the latest software and I have gone into options -device- advanced system settings etc and it says my handheld is registered for bb services. (But now when I go to options, I can't find the device option to re do this!). If I go to setup - email accounts, it tries to open up the emails I had set up it says checking etc then comes up with your device had a problem connecting to the server.
I've tried a battery out reset etc to no avail. If I click retry it just keeps coming up with the same message. I can access Twitter and Facebook on it (Twitter is slow and alerts take a good few minutes to come through).
My wifi is set up and working, I've got the 4/5 dots, i'm connected to 3G and have UMA in the top right of the screen. So everything appears to be the same as it was before the payment problem.
Can anyone please suggest what to do? Please keep it simple as I'm not that great with IT stuff, until I know what i'm doing!
Any advice will be much appreciated!!
thanks

Hi and Welcome to the Community!
I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):
1) Register HRT
KB00510 How to register a BlackBerry smartphone with the wireless network
Please wait for one "registration" message to arrive to your Messages app
2) Delete and Resend Service Books (pre-BB10 devices only)
KB05000Delete the service book for the BlackBerry Internet Service email account from the BlackBerry smartphone
If you have no CMIME entry, then skip the deletion
KB02830 Send the service books for the BlackBerry Internet Service
Please wait for "Activation" Messages, one per already configured email account, to arrive in your Messages. If you have no already configured email accounts, please wait 1 hour.
3) Reboot
Pre-BB10 Devices ONLY. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes.
BB10 Devices. Hold the top button down until the counter reaches zero. Wait for the device to be fully shut down (e.g., nothing at all displayed on the screen, no LED lights, etc.). Hold the top button until the red LED is lit. Wait through the full boot-up process. IF this fails, you can attempt the battery-pull method above, but it is normally NOT recommended unless nothing else works.
See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Hopefully that will get things going again for you! If not, then you could try deleting and re-adding your configurations for the affected email accounts. Otherwise, you should contact your mobile service provider for formal support.
Good luck!

When I updated my Mac, it won't connect to the internet when I've closed all Safari windows. I have to restart the computer every time to make it work.

Every time I update my Mac different problems occur. This time when I got an update notification, I went ahead and updated what it wanted. Now when I'm done browsing the internet and close the windows and try to open a new one, it says the internet isn't working. I checked the network diagnostics and it says everything is working fine. I've noticed I have to restart my computer every time to get it the internet to work now. This never happened before I did the update.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. First, disconnect all wired peripherals except keyboard, mouse, and monitor, if applicable. Boot in safe mode. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you will see "Safe Boot" on the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all, perhaps including wireless networking on certain Macs. If you usually connect to the Internet via WiFi, and it doesn’t work in safe mode, connect using an Ethernet cable. If you can’t do that, reboot as usual (i.e., not in safe mode) and perform a safe login, as follows: Enter your credentials at the login screen, then hold down the shift key and click the “Log in” button. Keep holding the key until the menu bar appears. In this mode, your login items, among other things, won’t load.
In safe mode, launch Safari and test. Same problem(s)?
After testing, reboot (if you booted in safe mode) or log out/log in (if you performed a safe login) as usual.

Mail won't connect to mail servers

This has happened before and my only solution was to reset the iPod.
I'm connecting to .Me and Comcast mail. The iPod tries and tries and won't connect. It worked fine just the other day and I believe it was working fine after the upgrade to 2.0.2. Mail would download very quickly.
Anyone else run into this? The Mail app just sits and spins and won't ever connect. I'll be restoring the iPod tonight but this is very frustrating.

My iPod Touch with latest software upgrade simply won't connect to my POP Mail Servers to retrieve mail. Oddly, I can send messages using the same Servers! GMAIL work fine.
I have deleted and recreated the account definitions many times and reset the iPod. I know the entered details (password etc) are correct.
It worked a month or so ago but has always been intermittent - I am sure this is a bug in the Mail application.
What is strange is that the SSL and Port Number keep getting changed after I set them to the correct settings. If I change them back they eventually change again to (SSL=Yes and some other Port Number).
This is my first Apple device and, while it is a great piece of hardware, the software reliability and support leaves me wondering why everyone has been panning Microsoft all these years.

IMac won't connect to the to the wireless network and internet when a laptop is connected

When a windows laptop is connected wirelessly to my router and the internet my Imac won't connect. If the Imac is connected wirelessly first it turns off when I connect the laptop. the iMac has once given me a message about the laptop using the same IP address. Can anyine help, I have been putting up with this for a year now and it's a real pain. Any help appreciated Many thanks
Joel

Check the company that you get your internet service from. High speed internet through a phone service modem allows for one connection as the modem is controlling the IP addresses. If you add a wireless to this connection, your modem will still allow for only one connection at a time. The wireless modem should be "in charge". Call the internet service provider and see if they will walk you through how to give permission to your wireless to assign IP addresses and not the modem they supplied.
If your Mac and PC both want the same address, you can tell your Mac to use a manual IP address. Go to:
system preferences/network
write down the IP address, subnet mask, and router numbers. On dropdown Configure IPv4 choose "using DHCP with manual address". Now put back in all the numbers you wrote down except in the IP address box, change the last digit to a higher or lower number.
Now the PC will be happy with the IP it chose and the Mac will, also.

TS3899 Device won't connect with email

My ipod touch stopped connecting with email a couple of weeks ago. I went through all the steps on the support website. After deleting the account from the device, I tried to add it back and now all I get is a message that says "the IMAP server "apple.imap.mail.yahoo.com" is not responding". I have tried multiple times and checked all info for correctness.

Try resetting your Yahoo password. That is how I resolved your problem on my iPhone.

IPhone 3G and iPhone 3GS won't connect wirelessly at home when PCs are off.

Dear Apple.com,
I have been using iPhone 3G and iPhone 3GS wirelessly at home no problems.
I use a MAC filter on an unsecured wireless network. Only entered MAC addresses can connect wirelessly.
However, when I turn off all the PCs at home the iPhone find the wireless network and show connected, but cannot browse websites.
The router Linksys WRT610N is always on, so the wireless connection and permission for the iPhone MAC addresses to access the wireless connection should work?
Any ideas?

Is your router a model that supports a/b/g/n? If you turn off N will it work? If your N is setup at 40MHz slots it may not work as well. Can you take your wireless router somewhere else for testing? I assume you might have some issue where you are at with your Mac and that router. When you open Apple Menu/About this Mac/More Info../Network/Airport does it show your network there? From a working machine can you see your Mac from your router web interface? FYI if your router was an Apple product(Airport Express or Airport Extreme/Time Capsule) you could see all your wireless clients via the Airport Utility, even signal strength and connection speed...

T400: Internet does not work when switching networks unless reboot?

Hi everyone,
I can't seem to establish an internet connection when I switch networks (e.g., internet at work, then at home). It gives me an error saying "limited connectivity" or failed to renew IP. This happens for both wired and wireless connections.
I tried turning off the firewall (comodo internet security) along with the windows firewall. I tried letting windows handle all my internet connections. Yet the error still happens. So I just have to simply reboot my laptop, and everything works 100%.
I never had an issue like this with other laptops. Could this possibly have something to do with some of the bundled Lenovo software? I disabled most (if not all) of them since I barely use them.
Thanks for your help. This is my 1st thinkpad, and I'm enjoying it so far.

Hi gatorman1122,
I had a similar problem with my T400. What wifi card do you have installed?
I had an Intel 5300. Networking was OK with XP Pro installed, but messed up with either Vista Ultimate 32-bit or Vista Business 64-bit installed. All were Lenovo OS images. I tried 2 different 5300s.
I only saw the problem with wifi, but basically if I changed access points or changed from wired to wireless, the first attempt to use the (new) access point would fail to get an address. An immediate reboot would cause it to succeed.
I finally got the issue escalated to a 2nd-tier tech. He sent me a 5100 to try. That fixed it. I doubt it is a hardware issue. It is most likely a Vista/Intel/Lenovo software issue/conflict. IMNSHO, ThinkPad wifi w/Vista is a mess. One of the most fundamental laptop features should work much better than this. Many folks have T-series wifi problems and Lenovo seems to be ignoring it.
Just to add to the excitement, I told a friend buying two new T400s to order 5100s to avoid the problem. He did, and got the machines with XP installed. They both exhibited the same bad behavior Once he updated XP and all the Lenovo stuff, they started to work OK and have stayed OK. Grrrr.....

Xp won't connect to wpa2-psk security enabled network

I have 3 laptops, 2 with win 7 premium and 1 with xp home edition, the win 7's will connect to the internet fine...but the xp won't connect at all, now if I turn off the security xp will connect fine, can anyone tell me what my problem is please?
Thank you Kindly for any help

1. Make sure, you verify under "Preferred Networks" click on the connection that's not working, click properties.
Verify WPA2 is an option in "Authentication". If it's not download the latest drivers for your wireless adapter, restart computer and check again.
2. Next problem is XP's Wireless Lan Manager; it is absolute garbage on XP for WPA2. I have seen many XP SP3 unable to connect to WPA2 because of this. You need to use the wireless manager that comes with your wireless adapter drivers. When
you install them opt to install with the software, not just the driver.

Event Code Error when switching networks

Although I am running a standalone version of P6 on my laptop, I continually receive event code errors when I switch between two networks. This often happens when I need to switch from a client network to my mobile hotspot. Or, if I'm away from laptop for any length of time and it 'goes to sleep' without having closed out of P6, when I return I will have an event code error that requires me to close and then restart P6.
I'm running Windows 7 SP1, Firefox 24.0, P6 Release 7.0.0 (Build 00000092)
Any help is greatly appreciated.

Hi,
In regards to the problem when the computer goes to sleep, if you look in the event viewer you will see that Windows is dropping the network connection - not sure of any other workaround to this than disabling the sleep/hibernate function.
As for the problem when you switch between networks, other than making sure you log out before making the network switch the only thing I can think of would be to try and make sure the connection is using 'localhost' or possibly '127.0.0.1' instead - this is in the vague hope that these connections will hold true even when the network behind the scenes is changing (this also assumes SQL Server, changing this for an Oracle XE database would be a bit different)
Good luck.
Regards
Alex

Ms exchange activesync problem when switching networks

i've noticed that when i switch networks (i.e. go from ny to sf), i land and set my phone from airplane mode to active, my iphone does not sync with my company's exchange server. it gives me a connection error. i then have to do a reset of the phone and it works fine.
this also occurs when i switch from 3G to edge and vice versa. i have to do a hard reset of the phone in order to get mail to work again. this doesn't occur with my gmail account, just my MS Exchange activesync.
anyone else notice this?

by the way, i'm running 2.0.1 firmware and this was not a problem with 2.0 firmware.

Mail.app doesn't hava connection with imap server when changing network.

Ive got a strange problem after upgrading OSX from 10.6.8 to 10.8.4.
I have got a xserve, with osx 10.6.8. (mail) server installed on it.
When i am in the office (LAN) mail works just fine. if iam home and wake my macbook from sleeping i see in the mail app the attention mark telling my something is wrong with the mail account.
If i open the connection doctor it say's can't connect to IMAP server. if i check my iOS devices there is nothing wrong, everything is working and i can send/recieve mail. on iOS and OSX the settings are the same with SSL enabled and password type.
When i tried to telnet the mailserver address with the IMAP or SMTP port i get a connection. so, there is no firewall blokking my connection.
But now the strange thing when i quit my mail.app and start it again the mail gets connection again. So is there a problem when changing networks when the Mail.App is stil active?

That's just to bad, will it be solved in a future release of OSX?
I don't know... maybe Apple will force me migrating to Mavaricks.
it seems that although w'r using DNS, the outside ip gets remebered or the connection isn't closed down properly when putting the macbook to sleep.
I can try offcource to configure the outside LANip (Non dns) in my mail client.
I will post with results..

Can no longer connect to email servers

Ok, I'm hoping some Mac gurus here can help me out. I've got a primarily Windows-based network here using MS ISA server as a firewall/proxy. Our prepress guys are on various flavors of G4/G5, Panther and Tiger.
On Monday, July 5 they suddenly stopped being able to connect to POP/SMTP servers. I have tried different servers, different mail clients, resetting network connections, giving them different static ips, etc.
I haven't made any changes to the network or the Macs... I wasn't even here on Monday:) Anyway I know there are a lot of variables but I'm just grasping at straws now. The mail server is fine, the account settings work fine from any other system. I can't even establish a telnet to the mail server from the Macs. Internet and network access is fine, however.
Thanks,
-sean

Thanks for the replies guys. That is indeed an interesting diagnosis tool but seems to confirm that traffic is actually being passed over 110/25.
colin - I thought about the cable, but can do email from the a pc connected to the same switch... should probably look a little closer anyway.
These guys do have their settings at full duplex but no other combo including 100/half-duplex or automatic seems to clear things up. I will look at this more when I am back in the morning though.
Thanks again,
-sean
