    I've never had a connectivity problem with my iPad using WPA or WPA2 (or no security) on a variety of routers including Netgear, Belkin, and Apple. This is over a period of almost one year. The iPad2 uses the same WiFi chip (Broadcom BCM 4329) as the iPad1, iPod Touch, Apple TV, and iPhone.

    That a correctly functioning iPad could not reliably connect to an Apple private network a year after introduction I find hard to swallow. If your iPad could not connect then this points to some problem with your iPad.

    Those that are having connectivity problems are likely having a router problem, a router configuration problem, an interference problem, a hardware problem with their iPad or some combination of these.

    One possible culprit could be an app we all share in common that could be causing these issues. Could simply be coincidence, but I noticed issues when Words with Friends tried to update my games... Signal dropped right away...

    JimHdk just for the fun of it I researched some of your posts. It seems that you repeatedly deny Apple has any bugs in their products.

    example: http://discussions.apple.com/thread.jspa?messageID=13079543&#13079543

    You persistently denied throughout that thread that IOS 4.2 made significantly slowed iPAD wireless throughput.

    To quote you:

    "Nonsense, Kucharski is completely correct. At this stage of the game, since iOS >4 has been out for months and millions of users have updated to it as well as >millions of new iPads (and iPhones and iPod Touches) and problem reports have >slowed to a trickle that this "problem" revolves around a few routers with >defective firmware and, perhaps, a few iPads that developed WiFi hardware >problems."




    However it was subsequently and conclusively demonstrated that iOS 4.3 returned the lost performance to the effected iPads. I see in reading that thread earlier today that you and the other deniers got strongly criticized for denying that iOS 4.2 caused the problem. Did you apologise when you were proved wrong?

    I would have thought you would have learned from that incident that just because a problem that affects many others does not affect you that it does not mean their is no problem.

    Your problem with swallowing is not the topic. You may be right that the problem in my case is a hardware issue with my iPAD... maybe many others experiencing the same wireless intermittent connectivity problem also have hardware issues. It's amazing how many people have been able to work around the problem by making compensating changes to their many different brands of routers security settings to improve connectivity.

    Could be, I wondered the same thing and so did one of the Apple support guys. But after I 'restored' my iPAD it had only the factory apps on it and it still exhibited the problem and I have never used Words with Friends.

    What was the longest sustained connectivity you achieved? My record using standard configurations (without implementing any work arounds on my router) was approx 3 hours. Though typically once the iPAD began losing connectivity it would happen every few minutes.


    Longest sustained connectivity? As I said, I've never had it drop a connection. At home, under WPA, maybe 3 days, although it was asleep some of that time. In my office, using WEP, about 8 hours. On unsecured networks, briefer periods of time.


    Did you use ask the store staff to implement WEP, WPA or WPA2 on their routers while you conducted your testing?


    No, I just checked functionality on their standard network in the Apple Store. You did not mention having them set up a secured network.

    Absolutely false.

    ...However it was subsequently and conclusively demonstrated that iOS 4.3 returned the lost performance to the effected iPads.


    There was no conclusive demonstration that 4.3 had any effect whatsoever on WiFi performance. That is absolute nonsense. My performance measurements with both iOS levels were identical. In fact, there are now plenty of threads here saying that 4.3 has "killed" their Wifi, etc. Which are reliable? The extollers of 4.3 appear to have disappeared.

    You have made some remarkable claims in this thread: that you have "solved" the WiFi problem, that you have seen internal Apple correspondence admitting the "problem", that you were going to help the Apple repair staff to "fix" their network. Where is the substance of any of this?

    As is usual with these threads the discussion has degraded to personal attack.

    I related my experience with WiFi on the iPad for over a year. I haven't had any problems with connectivity or performance. Believe it or not as you choose.

    All I can say is Apply WiFi is not the most compatible in the world. I help administer a few public hotspots and most issues comes from Apple Products. The issues are usually

    1. DHCP - many OSX pre 10.6 have huge problems with acquiring DHCP addresses. Sometimes need full reboot to get DHCP.
    2. AP password changes - again lots of problems that even "turn on/turn off" AirPort does not solve - but requires full reboot to reconnect.
    3. Indication of signal strength - does not work at all - seems programmed like the 3G signal strength was on iPhone before....

    My lastest problem was with iPad/iPhone on 4.2.x - they did not like to play nice with AP's with PowerSave technologies. The update to 4.3 solved that. But until it got solved modern AP's with Advanced Power Save would make internet browsing crawl to a halt. After 4.3.x this problem have virtually gone away.

    But I am impressed with how much the PowerSave AP's extend the battery life on the iPhone. A full day on iPhone 4 with a few call's and normal operation now only drains my iPhone to about 75-80% - where as before with "standard" AP without WiFi powersave it would have been drained to about 30-40%

    So in short - Apple seem to do some very agressive things to keep power consumption down. And they seem to impact interoperability with a lot of different access points. And WiFi Powersave is still a relative "new" thing - so expect problems.....

    Hey guys -

    I had the same problem on my iPad 1 with the latest 4.3 iOS. I found out the fix. You need to edit the wireless settings for your AP in your iOS device and where the IP is auto-configured, check the DNS settings when you are connected.

    You need to remove the IPv6 DNS entry. After updating to iOS4.3, my DNS server had 2 entries: one for IPv4 and one for IPv6. Remove so you just have, as an example, 192.168.1.1.

    Settings -> General -> Network -> WIFI -> Select the wifi connection you are using by clicking the blue right arrow. Modify DNS entry so it doesn't contain the IPv6. Hit back which will save. Then disable and re-enable wireless.

    Anyone try my DNS trick yet? It worked for me. The reason this is sporadic is some wireless access points don't provide an IPv6 DNS entry to its clients.

    Have you trie restarting your wireless router and your iPad?

    My wifi is working fine at the moment but I have lost my wifi signal symbol in top left corner although I'm still connected and using wifi.
    Anyone else got that issue?
  • Pbritain Level 1 Level 1 (0 points)
    I just picked up my iPad yesterday and started having the issue immediately. So far my work wifi, my home wifi and my evo 4g hotspot all have an issue disconnecting at a completely random interval. Sometimes it stays connected for an hour, other times it is 10 seconds.

    Other than that, I love my iPad.

    Regarding the statement from JimHdk and some of the other posters which are outright denying that 4.3 had any effect on WiFi Performance...

    My iPad was suffering badly from the problems iOS had in version 4.2.1, this was solved by installing iOS 4.3. I had not messed with router settings (which had an up to date firmware before of this fiasco) as all of my other WiFi devices were working fine and the problems only manifested after installing 4.2.1 plus I had the same problems in some locations when travelling, e.g. hotels, airports, etc. - my conclusion was that the problems were within the OS of the iPad and that they do not easily manifest. I think it is fair to say that most people will not have been aware of these problems or that they were not triggered on their device - but I find it ridiculous that some posters (especially those which are competing in the silly "I have more blue bars than you" game) conclude that just because their device is working fine in their environment, the same must be the case for everyone else. Plus, I find the motivation for such fierce denial rather questionable.

    Just because some WiFi problems seemingly are solved, this is no reason that there are not others or even new ones, as apparently iOS 4.3 introduced new problems like the ones discussed in this thread. Please bear in mind that there is a good chance that the root cause for the WiFi problems is the operating system of the iPad - switching of security of routers or messing up these settings by random might lead into further problems down the road, even if some seem to affect the WiFi performance in some ways.

    I believe the only way to handle this is to make these problems public and thus to put pressure on Apple to handle the problem professionally. With the 4.2.1 problems, there was no press release, no admittance, no statement, nothing, still there has been an obvious fix delivered some months(!) later with 4.3 - although it seems like it is still some way until the iPad works flawlessly in regards to its WiFi performance. As my iPad is now working nicely, I cannot reproduce the problems some people suffer from, so I cannot offer any advice - everything else would be guessing, meaning I seemingly "disappeared" (as some seem to confuse that "not posting" is the same).

    Kind regards,
    Frank

    It is still how meany of us are having this problem I have updated to iOS 4.3.1 with ipad2 and wifi keeps dropping I have looked in my router and it it has a very low connection speed some times as low as 1Mbps all the other 802.11/n divices connect at 130Mbps the most I can ge out of iPad 2 is 36Mbps when it is not dropping connection that is I have only had it just over 24 hours and I have had to reconnect about 100 times all ready well it feels like it it is every 2 mins or so I am sitting in the same place with the same router as when I had my iPad 1 that worked fine until the iOS 4.3 come out then that dropped wifi to evern now in the time I have typed this messages I have lost wifi AGAIN

    This seems a rather strong assertion. A "conclusive demonstration" would entail comparing two identical devices, one with 4.2 and one with 4.3, side-by-side preferably on multiple networks, with appropriate statistics. I haven't seen any such experiment published. Perhaps you can provide the particulars as to who did this test and how it was done? Did Apple make any claims that the update provided improved wireless performance? Forgive me for being skeptical, but you've previously posted similarly strong statements that turned out to be based on data that was shaky (to put it as kindly as possible), such as your estimate of the percentage of iPad owners with wifi problems that turned out to be derived from an online poll (and an old one, at that).

    It is certainly clear that not everybody is having the sort of problems you have reported. From the people I know who have iPads (none of whom have complained about such experience) and the rather modest number of people who have reported similar problems here, I get the impression that it is fairly rare, particularly considering that there are well over a million iPads in circulation. And we've certainly heard from people who had similar problems that went away when they updated their router firmware or corrected configuration errors.

    Of course, the fact that the problem appears to be rare does not make it any less of a problem for those affected. However it does imply that most iPads do not have a problem with most routers. This certainly corresponds with my experience, as I have yet to experience the problem you describe on any wireless network. So it could be that there is a bug in the iPad that only manifests with certain routers, or that certain routers have bugs that only manifest with the iPad (or both, of course), or it could be that there are some defective iPads that simply don't get consistent wireless reception with any router.

    In any case, it does imply that the problem should be fixable be either exchanging the iPad or changing routers. I've previously reported the routers I've used mine with most extensively: D-Link DIR-825 (802.11n) and DIR-655 (802.11g). We've heard from another person with the DIR-655 who also reports no problems. Is there anybody with one of these two routers who is experiencing the intermittent wifi issue?
