I'm also having connection problems since updating iPhone 3GS, iPhone 4 and iPad1 that we have... all of them now have wi-fi connection problems and I'm having bluetooth connection problems on the iPhone 3GS.
Reassured to see on these forums that I'm clearly not alone.
But doesn't seem to be a solution except I see someone has suggested changing the security settings from WPA TKIP to AES.
what is AES (my time capsule options are WPA2 personal and WPA2 ENTERPRISE or WPA/2WPA)? I Have similar issues since iOS5 upgrade. Have 3rd Gen Time capsule plus AE to extend network. Iphone 4 upgraded to iOS5 and new iphone 4S. Even read I should change DNS to 188.8.131.52 which seemed to correct problem for about 48 hours, now back to reseting network every 24 hours! Terrible!!!!
UPDATE......Called tech support and they essentially told me that the issue was with my router .... even though it happened not only with my home router, but also with the router at 2 airports and 2 hotels. Guess we have to fix a whole lot of routers out there.
After I convinced them that the this could not be the case they gave me the number of a local Apple store ( I am travelling on business) of course I called the number given and got a recorded message that "you have dialed an unassigned Apple telephone number". GREAT!!! So I quickly called Apple tech support and lo and behold they were closed for the evening (9PM eastern US time).
So I leave for the airport tomorrow AM back home and it looks like my Saturday morning will be spent at the Apple store near home before I leave on an international business trip Saturday afternoon! Maybe I can take a picture of myself and send it to my wife!!
This is ridiculous. Support tells me how sorry they are.... but are they really?
Glad I upgraded the OS 5 update.... NOT!!!! Of course they will not admit there is a problem. I mentioned that I have seen a number of folks that seem to have an issue on the discussion boards. The support guy tells me that he doesnt read the boards since he is too busy handling customer issues. This is how we handle issues???? Maybe they should spend some time reading the discussion boards!!
Sorry for the rant, but yes I am upset. If someone from Apple is actually paying attention and actually cares, let me know., Happy to post a retraction. In the meantime I am carrying my Apple iPaperweight!!!
Worked around this iOS 5 bug by downgrading router from WPA2 Personal to WEP encryption. WiFi connections now stable.
Network config is D-Link router used as WAP with routing turned off, connected via wire to TPLink router, connected to cable modem. Symptoms were iPhone 4S, iPhone 4, iPad 2, iPad losing WiFi connection every 5-10 minutes even though physically close to router, while Android, Windows and OS X clients worked fine.
In my case the WiFi remains connected, but somehow network traffic comes to a halt
every minute or so for 10-30 seconds, rendering my iPad2 pretty useless. My details:
* I have an iPad 2 running iOS 5.0.1.
* My wireless router is a Motorola SBG6580 router/modem.
* I had no WiFi problems until after the iOS 5.0.1 upgrade from iOS 4
* I have no problems with other wireless devices
* I used the "IT Tools" App on my iPad2 to test the network connection.
When pinging an IP address other than
my router, such as one of my ISP (Charter) DNS
servers, or a domain name such as google.com,
the ping test works normally for about a minute (about 40ms response every second).
After that the ping test gets no reponse for 10-30 seconds and
then goes back to normal. This repeats:
the per second ping test fails every minute or so for 10-30 seconds
(which is catastrophic for this device). I tried this for 10
minutes at a time. Overall loss is around 40% for the ping test.
* I did the same test using "IT Tools" with my router's IP address
and all the results were normal, showing that the WiFi remains
connected (the wifi icon was also at full strength (4 "bars")
throughout these tests).
* I tried using alternative DNS addresses (like OpenDNS) to no avail which is
not surprising given the ping results.
* In regular practice things like Safari constantly stall.
* I used PingPlotter on my laptop to do the same ping test,
all results were normal on the laptop, so it's not the router.
* On my router I disabled all encryption, n-mode, and WMM support to no avail.
* I tried using Settings/General/Reset/Reset Network Settings
on the iPad to no avail.
* I tried disabling as many network-related things as I could
find on the iPad, including bluetooth, iCloud, e-mail checks, etc.
This did not work.
In summary my iPad2 is pretty useless after upgrading to iOS 5, which
is probably due to a bug in the iOS network software.
Can anyone reproduce the ping results?
