I recently purchased the iPad 2 16GB WiFi only device. One thing I noticed, the WiFi will only work for a short while, then completely stop. I have to disable and enable the wireless to get it working again. Anyone else having this issue? Any resolution? iOS version is 4.3.
I have the same problem using a G only network. So it seems it is not related to N routers or mixed networks. Again the main issue of this thread is having full power for your wifi connection but no network connectivity after a period of time of it working.
I just set my home router to 802.11G only and seem to be having much better performance... My testing time is limited, but initial performance seems much improved!
Hopefully a fix is available very soon as someone pointed out I don't have much control over public places.
Here is an update on my IPad 2 experience since I stopped having wifi issues. It has been solid without one dropped wifi connection unless I cause it to drop. My wife and I used It yesterday for about 7 hours without a glitch. I had to to keep SSID broadcast enabled on my router for the connection to stay up. I normally disable SSID broadcast but the IPAD 2 seems to need it enabled.
IPAD Configuration:
Static IP
HTTP Proxy: Off
Router Configuration
SSID broadcast: Enabled
Encryption: WPA2 -AES
MAC Address filtering: Enabled
Mode: G Only
Channel: Auto
Wireless interface setting: Maximum Range
I had to make changes to my router to get the IPad 2 to work.
I mentioned in my other post that I have 3 Iphone 4's that connected without any problems. I noticed on other threads that people are having problems with their iPhones after upgrading to 4.3. So APPLE if you are reading these threads you need to take a serious look at 4.3. I was going to upgrade my iPhone but I'm going to wait..
I hope I don't come across as too stupid...but just in case I have WiFi issues when my iPad finally arrives, how does one "change" the settings on the router if needed??? All I did with mine was plug it into my Time Capsule and everything worked.
I have been troubleshooting completely inoperative wifi on my new ipad2 since Friday 3/11. Router is 5 year old Dlink DGL-4300 "Super G" (Atheros based) that has been solid with every other wifi computer device in the house. I was just about to give up and buy a new router, but I finally got it working last night.
The first thing I did was disable the Super G "Turbo" mode and switch from CH 6 to CH 11. That helped a little and made the ipad2 wifi barely work for just a few minutes one time. I then discovered that the ipad2 would connect solidly by disabling WPA2 encryption, but would refuse to connect as soon as WPA2 was re-enabled. Now the problem was definitely isolated to the WPA2 encryption between my router and the ipad2.
During the past three days of troubleshooting I ran across a posting in one of the forums about someone having ipad wifi encryption problems, and they were able to fix it by increasing the passkey length. I had been using a passkey phrase of only 10 chars, I tried raising it to 20 chars, but was doubtful that was it. Well BAM! The next time I went to connect the ipad2 connected right up within about 2 seconds and stayed connected solid and has been solid ever since.
If you are still having wifi connection problems
using WPA2, definitely try using a longer passkey of at least 20 characters. And on older atheros based routers, be sure to disable the Super G or "Turbo" mode because it does not play well with the broadcom based chipset in the ipad2.
I request the APPLE Team to please fix the issue of ipad getting disconnected from wifi after update to 4.3 ios. May be i should not have upgraded.
The ipad simply takes many finger taps to connect several times and its kind of frustating. It disconnects the wifi network only after 5 - 10 minutes without any reason. My Iphone with old software have no network problems. I never had any issue with network prior to upgrading.
I have been having the same issues with an iPAD '1' since upgrading it to 4.2. I was hoping that 4.3 upgrade would solve the problem.
Apple acknowledge that their are wireless connectivity problems but say only a small percentage of users are experiencing difficulty. Apparently approximately 8% (source: customer survey) of iPAD users are experiencing these severe wireless connection issues. Given the numbers sold 8% represents tens of thousands of users. Apple has now provided refunds on request to many of the people who have not been able to find a work around for this problem.
I was hoping that the intermittent wireless connection issues would be solved with 4.3 OS but alas for some people 4.3 just made things worse. I also hoped that the iPAD 2 would have offer improved wireless chip operation but evidently this is not the case.
Apparently the iPAD uses the Broadcom BCM 4326 WiFi/Bluetooth chip which implements Wifi protocols 802.11
a/b/g/n and has WPA2 AES encryption implemented in the H/W. WPA2/AES requires quite a bit of fast number crunching hence the requirement for it to be done in H/W in the chip instead of via a software process which would be very processor intensive. This chip is used in a number of other wireless devices and reportedly works well in other devices. Adjusting screen brightness has resolved connectivity issues for many users and is one of Apple's recommended fixes for this problem. This suggests that this wireless chip may possibly be suspect to power management performance issues. I suspect the issue is that under some circumstances this chip does not run fast enough in the iPAD.
I experienced the problem first hand. It occurred for me in both hot spot and my home network. I have done a bit of playing around and now like a couple of people in this thread and other threads I think this problem is related to security settings (actually I think the wireless chip is misbehaving in the iPAD implementation)
To confirm if your issue is security related temporarily disable WPA2, WPA and WEP modes in your router. (Please only do this a troubleshooting test as it leaves your network exposed). You may also be able to achieve stable operation by just switching to WPA. Several users have now reported switching to WPA has resolved their intermittend connectivity issues. Cautionary note! WPA was just a patch on the previous insecure WEP standard that prevented certain known insecure encryption keys from being used. WPA still uses the vulnerable TKIP encryption has some of the other insecurity issues of WEP. The later WEP2 which came out in about 2003 is quite different from WEP and offers much greater security especially when combined with AES encryption.
WITH WPA2, WPA and WEP turned off we have believe that your iPAD may then have a stable connection.
After doing this test please re enable WPA2 (Don't use WEP as hacking WEP is a reasonably trivial matter, whereas hacking WPA2 is non trivial).
Once you have re enabled WPA2, try both shorter and longer keys. Some users have reported that changing the key length has resolved their connection issues.
Please advise us of your experiences via this thread.
Which model netgear do you have? Please see my post a few post back on my netgear settings. My netgear is about 6 years old and has been performing great.
FastBikeGear, Thank you for sharing so much detail in your post. If anyone misses it, it's well worth reading.
I'm one that had to return my iPad1 and was hopping iPad2 had the wifi improved - guess not, so I won't be trying again. But, still following this thread, in case, something changes.
Thanks again for new information/insight I hadn't heard before. i.e. Apple acknowledges a problem...they wouldn't do that on mine.(s)
