Q: Getting page not found on iPad for WiFi verification

I had the same problem. For the moment I have found the following solution.

Went to:

Settings->General->Cellular

Turned off both "Cellular Data" and "Enable 3G".

At this point I could sucesufully connect to my wifi.

I then turned on again both "Cellular Data" and "Enable 3G".

For the moment it seems working.

I had the same issue on my iPhone 4 and new iPad.  But checked it 30 min later and although it did not connect the wifi network right away, when I manually did it, it went thru without needing a password (as it should).  Both devices now have wifi functioning normally, but I didn't have to reset anything....

As many other I had this issue after upgrading to iOS 6, but it's now working fine.

Yes, I've had this too.  Took me apple.com page that was not found and would not permit wifi access.  Also had an issue where couldn't connect to iTunes store.

Didn't work for me

I put my iPhone into Airplane mode and waited a minute.  After I took it out of Airplane mode, wifi worked fine.

I solved it by doing the following steps:

1. Go to Settings

2. Wifi

3. Click "Ask to Join Networks" ON

Can't seem to get this resolved with any of the workarounds in here.

I join to an 802.1x wireless.  When I switch my phone into sleep mode it disconnects the wireless.  When I unlock the phone it does not re-connect to the wireless until I manually select it.

I don't see disabling cellular data as a suitable workaround, and the "ask to join networks" option does nothing.

I don't know if this will work for everyone. But I tried connecting to the wifi, then rebooted my phone and then it connected perfectly.

Yea .. finally it seems to be solved now .. it took almost an hour for me to connect to my very own network ! Bummer !

I had this problem with Wi-Fi not working so I went into Wi-Fi settings and tapped "Other..." in Choose a Network...

I then proceeded to type in my SSID manually and password again. The Wi-Fi connection then stayed on as normal.

I had the same issue, just upgraded my iPhone 4 to iOS 6.

I don't know what resolved it, but it works by now, when I manually select the network. If I put it on standby and turn it off again, it does not reconnect to the wifi. I have to do it manually.

I get the extact same issue.  I haven't found anything to work yet...

Same problem. iphone 4

Here's my fix that worked:

settings>wifi>get info on network (little blue arrow to the right).

select "forget this network"

reboot iphone (or whichever)

settings>wifi>choose network, enter password.

Worked for me, hope that helps people.

I have the same problem before dinner today, on mya ipad3 and iphone4. After dinner they could connect normally
