IPhone 4 does not stay connected to internet over 3G+

I have an iPhone 4 on the telus network running the latest version of the os 4.3.3. My phone will not stay connected to the Internet most of the time. It looses connection and won't reconnect until I turn on airplane mode and then turn it back off. It also looses connection if I have wifi on and it detects a network but choose not to connect to it. I have restored my phone and it fixed the problem for half a day before it started again. I only have a couple months warranty left, is this covered do you think?

I don't have another phone to try. I took out the sim to check for deffects but it looked fine. Cleaned the sim card with alcohol and cleaned the aim compartment. Phone didn't loose Internet connection all day yesterday, but this morning went to check emails and wouldn't update until I turned airplane mode on then off again.

Iphone does not stay connected to wi-fi.

When using apps or when in sleep mode my iphone does not stay connected to my wi-fi. All other items within the house have no issues with staying connected to my wi-fi.

By design, when entering sleep mode, the iPhone will disconnect from WiFi to conserve battery. If you want the WiFi connection to remain persistent, plug your phone into a power source.

IPhone does not stay connected to iTunes

This doesn't happen to me every day or every time that i want to sync my iPhone, but maybe at least once a week or twice a week maybe...very strange.
So one day i was trying to sync my iPhone to my 2.4GHz MacBook Pro, and iTunes never opened (or if it was opened, it never detected the connection). I tried this numerous times in all 3 USB ports on the sides of my Mac.
An Erase & Install was recently done and restore from a Time Machine backup probably 3 months ago.
I wanted to make sure that it wasn't the USB cable, so i tried plugging it into the wall outlet to charge...of course, that worked.
So it's not the cable...but why is it not being recognized from either one of my USB ports? This particular day, i must have tried numerous times plugging it in to the different ports and it either never made the connection, or if it did...it would connect for a split second, start to sync, then disconnect in the middle of it....re-connect, dis-connect, re-connect...etc....back and forth and it wouldn't finish syncing.
I purchased the original iPhone on Day 1, June 29th, 2007, but this particular iPhone in question i just received as a replacement about 2 months ago....along with a new USB cable, AC wall plug, and dock....all replaced.
So i went down to the new Apple store that just opened up here in Pa a few weeks ago to have a Genius take a look at it. He plugged it into his computer there - it connected right away but he didn't leave it plugged in to see if the connection would stay or not, he just unplugged it and basically said there was nothing wrong with it.
So what exactly is it? It won't even let me restore it without it disconnecting...help please!? Thank you
Jason

Jason,
Your troubleshooting:
"I was trying to sync my iPhone to my 2.4GHz MacBook Pro, and iTunes never opened"
"I tried this numerous times in all 3 USB ports on the sides of my Mac."
"I tried plugging it into the wall outlet to charge...of course, that worked." (not your Mac.)
Apple store troubleshooting:
"He plugged it into his computer there - it connected right away..."
... his computer. (once again, not your Mac.)
See the pattern?
I will assume that you didn't take your Mac Book to the store for the Genius to check with your iPhone since you said he plugged it into his computer. Go back, but this time take your MacBook to the store as well. The problem might be in the connection between your iPhone and your computer. If that's where the problem exists, and not with the phone or cable, there's nothing the Genius could do. Pain in the butt to schlep your laptop to the store, I know, but it could help you get an answer. I'm surprised the "Genius" didn't suggest that to you.

IPhone does not stay connected to TC.

I am posting here since the iPhone maintains its connections with all other WiFi routers (and my iMac).
The TC is new, replacing the Airport Extreme with whom the iPhone strayed connected.
The iPhone automatically reconnects to my iMac when I go out to my other office.
The iPhone even reconnects by itself in restaurants that I haunt...
but walk into my home where Time Capsule lives -- no WiFi connection unless I manually choose it in Settings.
My dear old PowerBook 12" maintains its connections perfectly with the TC.
Any ideas? Any mysterious TC settings I need to discover?
Thank you in advance...

Fixed!
I found a tip on the iPhone discussions group...
Just go to the WiFi section of Settings, touch the right blue arrow next to the network's name, then touch "Forget this Network" -- this resets the historical data.
Now go back to the WiFi section and touch the network's name to join it.
Your iPhone should automatically rejoin your TC network!

Iphone 4 does not stay connected to my network

Since upgrading to 6.1, my iPhone 4 does not stay connected to my network. I have to input my password each time I leave my house. My other devices stay connected, so the issue is with the upgrade. Has anyone found a way to keep their IPhone connected to their network? Thanks.

IPhone 4S not staying connected to wifi?

I have both iPad and iPhone connected to same wifi, but my iPhone 4S does not stay connected. I have tried to reset network, restart iPhone and they do connect but disconnects shortly afterwards. Can anyone help me?

Did you solve this problem? My new MacBook Pro 15" running 10.8.2 has exactly the problem you describe with our new Netgear N600. The other devices in our house (iMac running 10.5, a PC and an iPhone 3Gs) have no connectivity probelms at all.
I have no problem connecting with my MBP at work or elsewhere. The problem is just at home with the N600.

WiFi does not stay connected after latest upgrade

I am having an issue with the WiFi connection on my Iphone 4 after the latest 4.3 upgrade.
It does not stay connected to the wifi. I have to go and manually connect to it.
Then after a couple of seconds it loses it again.
Why is this

"I'm not sure why yours is doing it but I would suggest your reboot your router and reset the iPhone network settings.
If you are hiding your SSID, do the last step which is tap Settings > WiFi > Other and completely re-enter your network name, security, and network password."
Been there, done that... Did ALL these steps, but that does not fix the problem... AFTER inputting the SSID manually, selecting security, and then the password, iPhone STILL says it cannot connect...

How do you resolve the problem of ipad not staying connected to internet. other laptops remain connected but ipad just disconnects after about 5 seconds.

how do you resolve the problem of ipad not staying connected to internet when other devices are connected. Ipad disconnects after about 5 seconds.

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
Additional things to try.
Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
On your iPad go to Settings > General > Reset > Reset network settings and see if that enables you to connect.
If none of the above suggestions work, look at this link.

Why is my iPhone 5 not staying connected to my wi-fi

Why is my iPhone 5 not staying connected to my wi-fi

I am so flippen ticked. I have been a iPhone, 3, 4,4S user for ever. I now made the mistake of going to an iphone 5 with update to iOS 6.0.1.
I cannot keep a wi-fi connection for the life of me. Nor can I keep even the weakest of signals to my cell carrier even if the phone sits still in one spot. While at the same time my ipad 3 with iOS 6.0.1 sitting right next to the phone has been up on the same carrier and wi-fi source for hours.
I am about to through the phone in the river and swear off Apple. This is frustrating after I use to talk about how good an iPhone was. Very Very disapointed.

58L7300U - Wifi does not stay connected

Comcast cable using a Xfinity branded ARRIS TG862 Wireless SOHO Router.
Two Toshiba 58L7300U TVs mounted on walls in residence.
LAN is setup and stable. The Router has been properly configured using WPA2 AES encryption. All computers (Apple, Microsoft Surface, Dell and Toshiba) access WiFi with no problems. All Smart Phones access WiFi with no problem.
The two Toshiba 58L7300U - they have a problem. Even PC Magazine has noted the issue in their test lab.
http://www.pcmag.com/article2/0,2817,2428099,00.asp
"The 50L7300U supports Wi-Fi networking, but the set was unable to stay connected to any of our wireless access points here in the labs. It saw each access point and would connect for a brief moment, but each time it would lose the connection. The wired LAN connection worked perfectly, however."
We've been through every possible setup. I was on the phone with Toshiba for 2 hours and they finally capitulated there was a problem.
Both TVs were purchased just prior to Chistmas 2013. They both have software version 7.2.67.31.01.1 (5/22/14).
If we get the TV to access WiFi I can use PING -T to ping the TV IP address. Yet the TV would say it can't get a connection. It is on the LAN. It has a TCP/IP stack and it can been seen from the POV of the Router and can be seen by another computer on the LAN.
One TV could get access, for a while. It could access Pandora and YouTube content. Then it LOST the ability out of the blue. Othertimes the TV would see the SSID and from the Router POV I would enable WPS and then have the TV do a "scan". Then it it would say it can't find an Wireless Access Point. I have done setups via; manual, assisted and use WPS.
All I can say is that there is a BUG in the software of the 58L7300U in accessing a Wireless Fidelity networks and for a $1,000 per TV that's atrocious.
Personally, I'd hard wire the units but the owner doesn't want that.
The owner spent $2K, and wants the product to properly access WiFi.

If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPhone. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
First, test your iPhone on some other WiFi networks: work (apparently has problems), a friends, Starbucks, Barnes & Noble, etc.
If it works well there then the problem is probably with your network. Try restarting your WiFi router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
If your iPhone does not function well on other networks it possibly has a hardware problem. You could try Settings > General > Reset > Reset Network Settings to see if that corrects the problem. If not, contact Apple Support or visit an Apple store for evaluation. They can provide a replacement if your iPhone is bad.
If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

Iphone will not stay connected "invalid response received from the device."

I have an older iPhone (8gb) and for some reason whenever I plug it into the usb port on my computer it will not stay connected whatsoever. Itunes freaks out, it'll come up for a little bit and then just as soon as it appeared, 'Josh's iPhone' disappears. When I say "won't stay connected" I mean you'll hear the "new usb device" sound over and over again continuously and the iPhone goes crazy too. Like it's connected, disconnecting, connecting, disconnecting, etc.. The error I get during all this madness is "itunes could not connect iPhone because it received an invalid response from the device."
I've used this ( http://support.apple.com/kb/ts1286 ) link to no avail (yet.) I am about to restart my computer right now. If it works after that I'll just simply delete this post. But anyway it's in a usb 2.0, it's plugged directly into the computer, etc etc
Also I'm not sure if this has anything to do with it but I put ringtones on the phone as well, I tried adding about 5 or 6 of them through itunes and it only uploaded two of them, except one of those two appears FOUR TIMES.
Thanks in advance for anyone who can help!

Okay, after the updates I am still having the same problem. I'll try explaining it as detailed as possible, hoping somebody has an answer because this is pretty weird to me.
-I have 5 files, Ringtone1.m4r, Ringtone2.m4r, Ringtone3.m4r, Ringtone4.m4r and Ringtone5.m4r.
-I add them to the "ringtones" section under "Devices"
-ON ITUNES they show up perfectly fine. In order, and if I play them through itunes, all the ringtones are correct, just how they should be.
-I eject iPhone, go to settings > sounds > ringtone, and under custom, what I see is:
Ringtone1
Ringtone1
Ringtone1
Ringtone1
Ringtone1
Why on Earth could this be?

IPhone 4 Not Staying Connected to my m1424wr router

my iphone 4 is not staying connected to the m1424wr router. how do i start the process with FIOS to check the rouret or get it swapped out?

What version of code do you have on the IPHONE? So, you could be in the middle of downloading email and it will disconnect? What are you seeing? The reason I ask is I have had different rev's of Actiontec, different apple devices and never really had a problem outside of some software fixes I've seen.
Do you live in a house or apartment? Is there interference from other wireless LAN deviecs?

HT4623 I want to purchase a ipad 32gb in the larger size but have read many bad reviews that the wifi does not stay connected and I don't want to have to buy another data package as I already own an iphone that i pay data for, what are my concerns

I want to purchase an ipad 32gb in the larger size buy have read many bad reviews that they have problems staying connected to wifi. I don't want to have to buy a data package so I only want the wifi one. I already pay apple for my iphone data and I can't afford more money. Why are there so many bad reviews and are the newer ones that much better, according to many reviews they are not.Please help

I already pay apple for my iphone data
You pay your carrier for data, not Apple.
Why are there so many bad reviews
Where? Regardless, there are always going to be a handful of people having some sort of issue with any given device, but I would not therefore assume that you would be one of them.

Our Ipad and one Iphone won't stay connected to internet radio while the third Iphone does. They are all IOS 5 ?

We have two Iphones and one Ipad. They are all IOS 5. We like internet radio. The Ipad and one of our phones disconnect from the radio program while the third works just fine. Does anyone have any thoughts? Could this be a setting somewhere we missesd? The one phone that works is connected to a different computer for sync and Itunes.

Kenneth-
One other thing you can try, is to reset (reboot) the problem iPad. Hold both the Home and Sleep buttons for several seconds until the Apple logo appears. Ignore the "Slide to power off" arrow. The iPad will restart after a couple of minutes. Resetting this way will not hurt anything, and sometimes clears up mysterious problems.
I'm not familiar with iPhones, but it may be possible to reset them the same way.
