Wi-Fi Connected, but no internet access

Dear all,

I've already posted this in a separate thread (https://discussions.apple.com/thread/3733104?tstart=0), but because I've had no replies and I'm so desperate I'm posting it again here (sorry if you've already read this).

Since about 2 weeks ago for no apparent reason, the internet on my iPad suddenly stopped working (when I open Safari, it says: "Safari cannot open the page because it is not connected to the Internet"), even though the Wifi icon in the top left corner still shows full signal. However, I noticed when I went into Wifi settings (Settings>Wifi) that there is no checkmark next to my network name (only the spinning circle icon, as if it's trying to process something). This only happens at home (I can browse the internet while connected to Wifi at university). My other Apple devices (MacBook Pro and iPhone 4S) work perfectly fine at home.

I've tried resetting my router, restarting my iPad, resetting Network Settings on my iPad, and tried following Hynes' instructions on this thread, but nothing has worked so far (although I have to admit that I found the instructions somewhat confusing, so there is a chance that I accidentally did not follow them properly).

Could someone please help? It'd be VERY much appreciated.

Thanks,

JF87

Hey. Sorry for this overdue reply. After almost giving up on the problem i was facing like others, my modem appeared to shut down on me and I had to get new modem and voila, no problem whatsoever. I have no slightest clue what went wrong but I thank you for all your efforts in trying to remedy the problem.

EVERY ONE JUST REBOOT (SHUT OFF AND TURN ON) WORKED ON 5.0.1 WIFI COMES BACK QUCIK WAY TO CHECK:GO TO iDevice WEATHER APP AND SEE IF IT UPDATES!!!!!!!

After going to Genius (right) Bar and trying everything I found online without success, I found the answer (for me, anyway). Went into my wireless router settings and increased the number of allowable connections from 5 to 50. Done. Next.

For Win 7 Users,

1. Plug iPhone into the computer

2. Wait or Open iTunes

3. Turn on your personal hotspot

4. Press USB only

5. Check your Open Network and Sharing Center to see it says "No Internet Access"

6. Open Safari in your iPhone and enter some random website and load

7. Check your Open Network and Sharing Center and it will say "Internet" next to the Access

For me, this is what solved my problem (I already posted this a few months ago here: https://discussions.apple.com/thread/3733104?tstart=0):

"So it turns out my boyfriend changed the Multiplexing Method of our router from VC-Based to LLC-Based in order to be able to play multiplayer Call of Duty online on the PlayStation 3; switching it back to VC-Based solved my iPad problem."

Can you provide the method to do this - increase number of connections in the router? I do not see the options to increase number of connections in my "netgear' router.

Hi,

I have the problem with my ipad 1 and iphone 3GS - connects to wifi/router but does not access internet. Also, this is a recent issue: it first happened with my iphone and then with my ipad. The problem is really a month old - everything was working fine. One day iphone stopped working (ipad was working just fine) and then ipad stopped working.

The wifi works fine on my computers (Windows 7) and blackberry - so data exchange, email, VPN all work. So this problem fumbles me. I did not change any setting on the router between the time it was working and now. I have tried everything - from resetting modem, router, ipad (upgraded to 5.1.1 today) - but solution is evasive.

I have a netgear wireless router. It is WEP protected. The ip address to ipad and iphone is 192... I have tried to remove WEP protection, but still not help.

Pls help with advise.

i am also having trouble with my wifi connection (ipod 4g). it has been three or five days since the last time i connected my ipod with wifi. it always says: "Safari cannot open the page because it is not connected to the Internet"), even though the Wifi icon in the top left corner still shows full signal. However, I noticed when I went into Wifi settings (Settings>Wifi) that there is no checkmark next to my network name (only the spinning circle icon, as if it's trying to process something). this happens to ALL wifi networks available. TRIED ALL THE SOLUTIONS SUCH AS RESETTING, RESTORING, AND FORGETTING THE NETWORK. 😟 WHAT IS THE BEST WAY TO BRING BACK THE USE OF MY WIFI ON MY IPOD? PLEASE? TY

ARE THERE NO SOLUTIONS FOR THIIIIIIIIIIIIIIIIIS?? IT HAS BEEN A WEEK SINCE I USED WIFI ON MY IPOD. 😟 IT REALLY DISAPPOINTS ME YOU KNOW! TRIED ALL OF TH EPOSSIBLE SOLUTIONS GIVEN HERE. 😟

My software firewall was blocking the connection. My company installs a software firewall security package and it was denying the connections from my iPhone. I had to permit the ip address that the hotspot network was trying to use and everything started working.

You can check for udp connections being blocked from svchost and see which ip needs to be permitted. I added it to my allowed ips and everything started working.

Hope that helps.

Iphone 4S: I went to Itunes, made a backup (right clicking in the iphone device name: backup) and began a "Restore"under "Version" in the main screen. Immediately Internet was restored. I cancelled "Restore". It is working since...

None of the solutions worked for me and I had given up until I tried something on my own and IT WORKED 🙂
Ok here is what I did -

1. Reset My router, changed my wifi name and password. (Don't forget to RENAME it)

2. Turned on wifi on 4S.

3. I had to enter all the settings in "STATIC" (IP address, subnet mask, router, DNS)

4. VOILA, it starts working again.

Strange bug but this has fixed it for the moment.

Hope it works for you all as well. cheers!!

Did you find a solution? I have this problem too.

So frustrating!!

I just fixed mine. Do this

Go to wifi

Find your wifi connection and select the arrow ( blue on right of screen)

Select renew lease

Enter apple id pass word

Fixed
