Cannot connect to the PSN? MTU settings changed

Good morning, I've been having an issue with the console over the past 2 days, where I am not able to connect to the PSN. It occured yesterday morning without any signs or for any reason. I didn't have a power outage, network connections were not interrupted. I signed off yesterday morning for a few hours, I then went to re-connect and couldn't.
I have read online that changing the MTU settings helps, and I had a little joy last night for a few hours where I was able to connect with MTU codes 1472 and 1473, however this morning I'm back to not being able to connect. I have tried unplugging and resetting all consoles and network devices, and I have reset my network settings back to factory, but I have had no luck. SONY are saying the servers are fine, but I am connected to the internet fine on my console and can browse, and use apps like Netflix and the BBC iPlayer. A various number of my friends and family are having the same problems nationwide so I doubt very much whether it is not something on SONY's end. Any information regarding this matter, tips and tricks or if anyone is having the same issue, please reply. Would be good to get some idea of what people are doing to solve this, if anything. Thanks for reading,Sam

Since you changed the password on the router, you have to input the new password in the printer.

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.

Hi richardwilliams51,
If you are having difficulty connecting to the Internet using your Apple TV, I would suggest troubleshooting using the steps in this article -
Apple TV (2nd and 3rd generation): Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/TS4546
If that does not completely fix your Apple TV, you may need to restore it, using this article -

Thanks for using Apple Support Communities.

I cannot connect to the internet. I think I have my settings all out of whack now and need to get them back to the way they were when it was working. (I know my wireless router is working because my Dell has no problem connecting to the internet.)

I cannot connect to the internet on my iMac through my wireless router. I think I screwed up the settings and need to reset them. I know the router is working because I can access the internet on my Dell laptop which is located right next to my Mac.

On your iMac try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
In the windows on the left side: Select login for Keychains and "All Items" for Category.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

WIFi needs to enabled and you need to be connected to a network. Alternatively, you need Cellular Data to be "on". (Settings>General>Network). But it propably is a problem with your router (at least, it often is with me), provided you are using your private router. Try schutting it off and turning it on again. This usually sorts problems like this out.

I am trying to connect to my friend's wifi, i have a very strong signal indicated on my ipad, but cannot connect to the internet. Yesterday i connected without any problem, can anybody tell me why i cannot connect today?

I get a message that my ipad and iphone cannot connect to the iTunes store. I have tried to sync books to my iPad and iphone and i get the message that I cannot connect to the iTunes store and thus cannot sync a book to my books app. Why?

I get a message that my ipad 2 and iphone 5 cannot connect to the itunes store when I try to sync a book to my book app. Although, when I click "store" both are able to access the itunes store. Why is this? Also I tried to open a book that was synced and a message that I did not have enough memory to load this book popped up--when I know that I have well over 40gb of memory left in my ipad and over 16gb left in my iphone. The message that I cannot connect to the itunes store is strange that it offers no option and I have to hit OK to get out and use my ipad or iphone.

Try logging out of your account on the iPad by tapping on your id in Settings > Store and then log back in and see if it then works.
If that doesn't solve it then what has worked for some people is going into Settings > General > Date & Time and changing the date to a few months (or maybe a year or two) in the future and then re-trying

Cannot Connect to the iBooks Store

When I open the iBooks store in Mavericks I get "Cannot Connect to the iBooks Store". Also, in Safari anything it cannot connect to anything that uses HTTPS (secure/encrypted connection) such as Twitter. However I do not know if that persisted from Mountain Lion, as I use Firefox. It is solely with my computer, the other mac on Mavericks connects just fine. However, here's where it gets strange. My iPhone, which I have my keychain synced to, does not have a problem. Additionally, the iTunes Store on iTunes can connect to the books section. I've tried going through my certificates and resetting them to Use System Default, using First Aid, changing my MTU in Network Preferences to 1300, and fixing disk permissions, but none of that worked. I have no proxies and no DNS servers.
I'm getting this error in this console whenever I open iBooks: NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813).

I have exactly the same issue as describet by "bengersfoo", i.e.
"I can find exactly the certificate that pavelfrompraha mentions, and it is set to "Always Trust".
But I cannot reem to reset it to System Defaults. When I choose that option it has always reverted to "Always Trust" whenever I check again."
It would be very helpful if someone could please explain how to make the "System Defaults" setting stick.

Error: "Cannot connect to the provider. Make sure it is running in the specified host/port. Error (12031)"

Hi,
EPM version: EPM 11.1.2.1
When we are using Zoom In Level as All Levels and tring to drill down for dimention of HFM application we are getting below error.
Error: "Cannot connect to the provider. Make sure it is running in the specified host/port. Error (12031)"
As we found some solution from comunity , we have performed below workaround but still we are getting same error.
·              We have done the changes in mod_wl_ohs.conf file of OHS with (WLIOTimeoutSecs 3600 and WLIOSocketTimeoutSecs 3600)
·              And then restarted OHS and APS service but still we found same error.
Could anyone please suggest ,where can we trace its log from web server and the solution for this issue?
     Thanks,
         D.N. Rana

Hi,
We have already performed the changes for APS in OHS as mentioned in the solution and the path also same as under OHS.
Intially we were getting error for "to increase netRetryCould and NetRetryInterval" as a solution we have added below 3 registry DWORD keys under path
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
"KeepAliveTimeout"=dword:00180000                   (26 Minutes)
"ReceiveTimeout"=dword:00dbba00                      (240 Minutes)
"ServerInfoTimeout"=dword:00180000                  (26 Minutes)
Above error resolved but then we received Error"12031"
Now we have added above 3 DWORD keys under path HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
and now we are not getting the error "12031".
But here we are not getting how it(LB issue) resolved with above solution?
Thanks,

I can't update my applications. Always appeared cannot connect to the iTunes store

I had the same issue all i had to do was go into settings > general > cellular > itunes > ON then go back to the first settings > iTunes & App Stores > Use Cellular Data > ON

Hope this helps everyone and maybe apple will let everyone know that after the update some phones automaticly switch cellular use off, i tried everything from changing the date forward to factory restoring my phone none of which fixed it
GOODLUCK!

Applicaton Catalog - "Cannot connect to the application server" - Existing solutions have not worked

Hi there,
I have researched the problem below extensively online and found quite a varies array of solutions offered however they all seem to relate to the problem in that someone was setting up SCCM but couldn't get it to work. My situation is different in that the
feature was working, no settings were changed however it has now stopped working.
The issue is that if any user attempts to use the app catalog, they are shown the error screen which says "Cannot connect to the application server". It then says the problem might be temporary, try again later etc however it's not temporary.
All the settings for the app catalog appear to be correct, as I would expect them to be as it was working (I am new to this company, the Desktop manager has told me it was working a few weeks ago).
Does anyone know of a service in Windows, maybe something to do with the SQL side or certificates that could cause this issue? (although I checked certificates and again, looks fine). I'm almost at the point now of just restarting the server because
if all else fails, turn it off and on again right?
Cheers all.

Hi, I just typed a long reply to this and then accidentally clicked a favourite on the Favourites bar and lost everything I typed :(
-Checked the path in IIS to the \SMS_CCM\CMApplicationCatalog folder was OK and it was.
-Checked that required .NET components including WCF are installed.
-This one seemed a bit strange but ensured local service account has access to C:\Windows\Temp (this seemed very basic and unlikely but I tried it anyway due to desperation).
-Checked that self-signed certificate was trusted by my PC attempting to access the App Catalog.
-Checked SCCM services on the server are all running (where they should be, or set to manual as appropriate).
I'm sure I've tried more than this, but these are the main things I can remember.
Cheers.

Networking - No Internet - Cannot Connect to the Server

I have an old Intel Mac Mini running Leopard (10.5.8, I think) and connected to a wifi network created by a Time Capsule connected to a DSL router. I use the Mini (connected to a widescreen TV) mostly as a media center for Hulu, Netflix, iTunes, and iPhoto. The wifi network works fine for my laptop and iPhone, etc., but for some time now neither Safari nor Software Update has been able to access the internet from the Mac Mini. Instead I get a message that 'Safari cannot connect to [the URL] because Safari cannot connect to the server', and a recommendation to check my internet connection and try again. But I appear to be connected to my wifi network, Network Diagnostics says my internet connection appears to be working normally, and--most important--iTunes DOES connect to the internet to download podcasts etc. without any problems. I went to Network Preferences > Security > Firewall and found that iTunes was set to allow connections while Safari was set to block them--but authorizing Safari to allow connections didn't fix the problem even after a restart. (Also, because Software Update doesn't show up in Applications or Utilities, there doesn't seem to be any way to select Software Update under the firewall, which is understandable but also suggests that the problem is elsewhere.) So I turned the firewall off entirely and restarted but that didn't help either. Does anyone have any idea what to do? Thanks.

Camelot-
Thanks. I see it but I don't know what it means: The pane is set to configure proxies manually (the only other option is to configure using a PAD file). There nothing checked under 'Select a protocol to configure' and nothing entered in the 'FTP Proxy Server' box. In the 'Bypass proxy settings for these Hosts and Domains' box there are two entries (separated by commas) for '*.local' and 'nnn.nnn/nn' (with the n's representing numbers). The 'Use Passive FTP Mode (PASV)' checkbox is checked. Does anything here sound problematic, or is there anything else I can check? Also, FYI, iTunes stopped connecting too after I had started downloading small podcasts individually to check the connection after making various changes to the firewall (but restoring the firewall back where it was didn't get iTunes back). Thanks very much.
