Constant Drop of 3G Network!

Hi there,
I've had many problems with the network and was looking to see if everyone had the same issue or it was just me. I've updated my OS to 3.1.3 but what happens is, is that 3G constantly seems to turn off every 2 minutes or when I am sending a lot of traffic (using the web or sending messages). This is really starting to frustrate me and none of us should be forced to switch to EDGE.

I was wondering if this is the most common problem, because literally just today this started happening to me, and not just dropping off of 3G but also off the AT&T network.
It keeps attempting to reconnect and will do so for a while as long as the phone is in stand by mode, and will also connect to the Edge then drop off again the minute I go to use either of them.
When I turn it back off it will furiously search causing my monitor image to shake, which Im assuming means its trying pretty aggressively to find a signal.
In case it help diagnose anything what I was doing when it failed: Listening to local radio on an app, exited the app to respond to a text then go no service. Did a soft then hard restart to no avail.
Thanks!

Problem with internet. When i open System preferences, Network, message drops down: 'your network settings have been changed by another application'. I click OK, but it drops a message again and again, preventing me to do anything about the setting.

My fix for the AE dropping off the network in client mode

Turn off any encryption.
I have the linksys/vonage/wireless G router, which supports WPA. The AE will sometimes join the network with WPA but it takes anywhere from 1-5 minutes for it to do so. When finally on the network it shows up on the Airport manager list and in iTunes. The most playtime I could get out of it was 15 mins, before it would drop from the network. The light on the AE would be solid green, but I couldn't ping it. The only solution was to power cycle the AE. Note this is dropping w/out running the microwave, cordless phone, verifying my network channel is different from my neighbors, etc.
I tried fiddling with WEP but the only way I could get that working was to specify the full key in hex, appearantly Apple and Linksys don't agree on the way to take a passphrase and turn it into a key.
So I dropped to the unencrypted network, disabled the SSID broadcast and restricted wireless access to my machines. Works great now. :/ If I run the microwave and the cordless phone at the same time I can get Airtunes to drop, but it comes right back when the microwaving is done.
Very frustrating, and the part that is the most irritatating is that my mac laptop and iMac can get on the network just fine.
Still deciding if I want to keep it this way or say nevermind and return the AE.

I found the solution after many many many attemps.
It's not a MBP problem, it's your wireless router.
1- Set your BEACON between 20 and 50. D-LINK router for example use 100 has default value. It's too long.
2- Change your channel. D-link default is 6. Use whatever channel. I use 10.
Hope you enjoy!

Officejet 4620 drops off the network after the first operation

HP 4620 drops off the network soon after one operation is performed. I have to turn it off and on again to bring it on line and then it repeats. The message is " unable to communicate with printer". I have run all the diognostics and they say your printer is operating normally. I have down loaded the latest drivers. Running Win 7 (64 bit). My only clue is that I have a new router, Netgear.

Hi LennieZup
I understand you can print over the network one time and then you have to turn the printer off and on again to continue to print.
I will be happy to assist you with this.
It may not be the printer, it may be your router's inability to wake the printer.
Disconnect the power cable on the router for 10 seconds, then reconnect the power cable again. You might need to check to see how many devices can be setup on the router at the same time. Depending on each router.
I would recommend updating the printers firmware. HP Officejet Firmware.
I have included a document for Printer Does Not Maintain Wireless Connection. Try Step six: Assign your HP product a static IP address.
If you need more assistance just let me know.

My C7280 keeps dropping the wireless network but my C7180 is okay

My C7280 keeps dropping the wireless network but my C7180 is okay both have set IP addresses, both in same room and the C7280 has to be setet to see the wireless. It will work okay all day but the next day it has dropped the network.
Any ideas

What operating system? There is an update for "Windows 7 Critical Update to enhance reliability of network connection", the version for 64 bit Windows 7 is here. If you have a different operating system check HP's download page for your appropriate operating system and look for updates.

Time Capsule connectivity drops on extended network with Airport Extreme

I have a new Airport Extreme router as the main router in my network and a Time Capsule set to extend the 2.4Ghz network. The routers must be configured in this order because I want the 5Ghz network from the Extreme to cover my main seating area.
The problem I have is that while I'm connected to the Extreme, on either the 2.4Ghz or 5Ghz network, the connection to the Time Capsule will 'drop'. The network drive within the Time Capsule will no longer be available and the AirPort Utility no longer shows the Time Capsule. If I reboot the Extreme, the Time Capsule will reappear.
Also, when the connection drops, if I were to move within the primary range of the Time Capsult and connect to the 2.4Ghz network, it will connect flawlessly and I would have access to the Time Capsule and it's resources. It is only access through to the Time Capsule through the Extreme that is no longer available.
Any ideas what could be causing this? Both routers work flawlessly otherwise. I'm fairly certain there isn't a hardware problem here. I've gone through all the configuration settings multiple times and can't find anything that could affect this. I have the latest firmware for both routers and the latest AirPort utility.
One thing to note is that the Time Capsule is a North American unit, while the Extreme is from Hong Kong. I know there are slight differences regarding the wireless channels that both can use, but I don't think this is an issue since the Time Capsule maintains proper internet connectivity the whole time. If it was a channel issue, I'd expect the Time Capsule to lose internet access when this issue arrises.
Any suggestions are greatly appreciated!

7.4.2 firmware does NOT resolve this problem.
I also have this problem -- it started about 2 weeks ago (around July 20?), possibly at the time the new Airport Extreme firmware went into effect. I have two separate Mac laptops that each use Time Machine to back up to different disks that are attached to the Airport Extreme (i.e., each laptop has its own backup-destination disk). Both were working flawlessly before (for more than 6 months); now, each one reliably drops the connection to the disk (produces an error message, and thereafter cannot re-connect to the destination disk until I cycle the Airport Extreme with power-off/on). I had hoped that 10.5.8 would help (the release notes talked about improved stability with Airport connections), but not so.

Why does wireless on my Time Capsule (2TB, 3rd Gen) drop the wireless network now?

Starting a couple of weeks ago, my Apple Time Capsule (2TB, 3rd Gen) has been dropping the wireless network almost daily. I end up pulling the power cord to restart it. I've had the device for what I think has to be about a year and a half already, and it's been working flawlessly until now. I have it on 802.11N (dual-band), using WPA2, with an average of about 7-8 client devices at any one time throughout our home. The problem doesn't appear to be any one client, since all lose connectivity at the very same time. The Time Capsule LED is still green when it's down, and again restarting it solves the problem. The device is out in a well ventilated area, and doesn't feel like its overheating. Devices using Ethernet to connect are unaffected (other than losing visibility to wireless network elements). It can occurn at any time, day or night, seemingly at random. The Airport Utilty advises that I have the latest firmware version (7.5.2).
Anyone have any idea whats going on? Having similar problems? Fix, workaround, suggestion?

Try setting the wireless to manual and fixed channels.. the auto channel swapping does cause issues.. I would also give different names to 2.4ghz and 5ghz so you know clearly which wireless you are connected to.
But sometimes they do just go bad.. power supply is not robust. They do become unreliable.

Sky Fibre constant drop out and low speed

Hi everyone,
Just recently switched provider from Plusnet fibre to Sky fibre and boy, has it been a stressful few days. First off, our fibre went live on the 6th of this month but these last couple of days I've been experiencing low speeds between 10-20 mb which I understand is meant to be normal (Never had this issue when I joined plusnet) and I have constant drop outs when I'm surfing the net or playing internet games on my Wii U
I've phoned Sky within the last two days and told them what's going on and they've done some tests on their end and they are telling me that I'm getting speeds up to 41 mb which I'm not getting, but they can't seem to understand why I keep having this drop out issue with my devices and my laptop and my gaming console. They have sent me a new hub, but I personally don't think sending out a new hub will make a difference. I've stuck a a Ethernet cable into my Sky fibre router and attached a openreach router, to the other end and see if that stops the drop out.
I'm inclined to leave sky, because I have a feeling this poor service will continue, unless someone can help me.
Thanks

IOS 4.0.1 - call drops in 3G network, but not Edge network !?!

Upgraded my iPhone 3GS to iOS 4.0.1 and have had dropped calls ever since. Never had dropped calls before. Messaging, emails and internet are fine, but all calls are dropped, even with 5 bars! The only constant is that I've been on the 3G network when the calls dropped, so I turned it off and have been on the Edge network for a few days without issue!
I have hard-reset my phone at least a dozen times and even restored my phone. I do not have bells & whistles installed.
Is this a traffic issue on the 3G network? I live in Hawaii, where there aren't tall buildings to block my signal.
ugh.

Since upgrading to iOS 4 it seems to me that the signal bars are reversed. In an area where I used to get maximum bars, I now only get 1 or 2. In an area where I never got reception at all (no signal zone) I am suddenly getting 5 bars, but guess what - I can't connect to anything, or send anything from there.
Either the latest upgrade has just sent the aerial dotty, or someone at Apple IT messed up when writing the signal strength algorithm.

Constant Disconnection from Cellular Network

Hi There, so I've gotten my iPhone 5 32GB since July 2013 and I honestly adore the phone however, there is a problem i'm facing with it quite recently.... the phone keeps disconnecting from the cellular network carrieer every 10 secs of the day... so...I'll start up the phone it connects with 5 blocks of reception.. then it drops to four...then to 1... then it completely disconnects itself from the network and the Edge sign disappers and then 5 secs after it connects back. I dont use my phone much to talk.. however.. it messes up my data plan, i can't even make a call that is more than 10secs... it drains the battery life and I have to wait every few secs to send a whatsapp mesg/fb etc. . I spoke to my carrier... they used different sims of the same network to see if its the sim card itself being the issue.. but its not.. we even used another network's sim.. but no difference.. What should I do?
Sincerely, Stefan (first time Apple user)

IPhone 6, iOS 8.0.2, constant dropped Bluetooth... a solution

After reading many, many, many postings here on Apple Support and all over the web about the iPhone 6 and iOS 8.0.2 and how Bluetooth connections in the car are being dropped all the time for all different makes and models of cars, I figured I'd post my "adventure" and how I solved the problem. This was posted as a reply to another posting, but I figured I'd start a new thread so people can find it easier.
Here's the posting and solution:
I had the same exact problem with my iPhone 6, running iOS 8.0.2, when connecting to my 2014 Ford Fusion with the My Ford Touch (MFT) system. Calls would "drop" after about 10 to 15 seconds. Only it wasn't the call that was dropping, but rather the Bluetooth connection crapping out.
I found the answer (which I will list at the bottom of this posting), but first here are the many things I tried BEFORE I found out the answer:
1) updated 2014 Ford Fusion MyFordTouch with latest firmware upgrade from Ford (v.3.7).
2) Unpaired and deleted iPhone 6 from MyFordTouch
3) Deleted SYNC from Bluetooth in iPhone 6
4) Reset Network Settings in iPhone 6
5) Did Master Reset to MyFordTouch system.
6) Added iPhone 6 back into MyFordTouch
7) Successfully paired iPhone 6 with MyFordTouch
8) STILL dropped calls after ALL that.
The answer I arrived at after chatting online with Apple Support Reresentative ("Emmy").   I backed up my iPhone 6 to iTunes (even though I don't normally like to use iTunes), then used iTunes to do a RESTORE to my iPhone 6., which effectively downloaded a virgin copy of iOS 8.02 to my computer and then iTunes applied it to my phone. This RESTORE function completely WIPED my phone clean (so I had to make sure I did a backup otherwise I'd have lost everything).
AFTER the restore of iOS 8.0.2, the iPhone started to walk through the setup. BUT here is the IMPORTANT part. THIS TIME, I said, "Set Up as NEW Phone" instead of "restore from iCloud backup" (like I had been doing). I skipped the signing in with my Apple ID and all the rest and got to the Home screen.
Then I went out to the Ford Fusion and paired the iPhone 6 to the car.
This time NO dropped calls at all. Worked perfectly. I spoke with a friend for over 5 minutes and the call sounded great.
THEN, Emmy (support rep) said to do an "Erase All Content and Settings" and to do it OFFLINE (meaning NOT to connect to iTunes). So, iPhone 6 was wiped again. This time when it came up, I *DID* do a "Restore from iCloud Backup" and restored the phone.
After the restore, I shut the phone off. Went to car. Deleted the pairing from previously on the My Ford Touch system.   Then took key out, opened door, and closed it (thereby "rebooting" My Ford Touch).    THEN I powered up my iPhone 6.
Paired to Ford. Pair to iPhone.
And.... it WORKED. And continues to work.
So... I'm not exactly sure why this worked. The only thing I can figure is perhaps the iTunes RESTORE that I did, wiped everything and left a clean iOS 8.0.2 and then when I did the restore from iCloud it laid on only what was not already on the iPhone in a newer state.
After you read all the above, and after I typed this, I realize that this is a LOT to do just to get back Bluetooth functionality.
I'm thinking that Apple should release an 8.0.3 or an 8.1 update that will address all this for people that don't have over 3 hours to do what I did above to restore functionality.
I've seen other posts and this is happening to ALL car makes and models, not just Ford.
Hope this helped some people.

Even easier than what I wrote originally.    Just do a RESET ALL SETTINGS . I was originally only trying the "reset network settings" but didn't try reset ALL settings.   This has helped 5 of my friends regain their Bluetooth connectivity with a variety of autos.   But remember two things: 1) back up data on your phone before trying this and 2) don't forget to delete the bluetooth original pairing from your car.

Any advice on my mal-configuration or possible sign of hardware failure or... greatly appreciated.
Thanks,
peter

I am at the latest firmware - which was already out when I bought my Extreme.
Before downgrading, I'll try to find the release notes to see what "features" I will loose
I am using the "full feature set" of my base station, channeling all traffic to my network through it. Thought (without basis) that the reeboots had to do with "load". The reboots erases logs, so next step will be setting up syslog on a different machine

SQL developer drop all my network connections

Hi all,
I have used different versions of SQL Developer and I have read many forum posts but I cannot find solution for my network problem.
I can connect to my databases without any problem, but when my session goes to snipped state (due to idle_time setting) after some time ALL my network connections are dropped (e.g. my mail client give me message that cannot connect to the server, my ftp client session is dropped, my ssh session are dropped...). It is horrible because sometime I need connect to my PC remotely and due to this problem I cannot. It is not problem of my PC, I have used 2 different PCs and all is the same. If I don't start SQL Developer, I can have ssh session open for week without any problem.
Last year I used to start keepalive extension, but is really annoying for every oracle session manualy enable keepalive.
And when I open 10 db sessions and for one session I forgot click enable keepalive then all my network connections are dropped.
Yesterday I have installed current version of SQL Developer hoping that the problem is solved but today morning I find all my network sessions dropped (e.g. I need 8 ssh sessions reconnect).
Does anybody have any idea how to solve this?
Thanks.
Marian

Hi Marian,
I am not quite sure how using SQL Developer could make all client software accessing the network lose their connections. Do you use some kind of VPN (Virtual Private Network) software? Do you always try to use SQL Developer with the non-Oracle KeepAlive plug-in?
Maybe local policy imposes some limit on the total number of simultaneous connections (active or inactive) you can have, and it gets exceeded only when you run SQL Developer. Are any other application clients used to access databases from your machine(s)?
If the real network connection is stable, typically one need only worry about database session time-outs (idle limit reached) or VPN time-outs. I suggest asking for help from someone inside your organization responsible for networks. It seems like something is forcing a VPN disconnect.

Gary

IPADs and IPhones dropping off wireless network

I have a site with a number of iphones and ipads that are attaching to a Wireless network managed by a lan controller ( cisco 2504 )
but they seem to drop off every 16 minutes .... and can then get back on a few minutes later.
Any ideas appreciated.
Thanks

Right now I have it in the setting; "(OFF) Bridge mode". Do you know if the airport extreme if the internet bottle necks will crash?

Apple Devices Dropping Off Wireless Network

Hello, I have recently deployed a wireless network using a WLC 2504 with 21 Light APs. All seems fine except that
Apple Devices drop their connections every 15 minutes or so. A couple of minutes later they can reconnect but
obviously something is wrong.
Many Thanks

Only Apple device exhibit this kind of behaviour?
What kind of Apple devices? Mac laptops? iPad, iTouch, iPhone?
Have you seen this behaviour from, say, non-Apple devices? Android? Windows laptops?
What are the signal strengths when this happens?
Do you have Aironet IE enabled?
How far are the clients from the WAP(s)?

Constant Drop of 3G Network!
