    How can software cause this issue? I put my physical hand on the material iPad, and the signal drops out.

     

    I'm not sticking my hand into the software, or even doing anything software related, I simply place my hand on it and it dies, that is a physical problem of my hand blocking the un-shielded wifi.

    I think that there are two or more issues going on here.

     

    1. Landscape orientation/"death grip".

    2. Weak WiFi/dropouts/cannot connect.

    3. Something else?

     

    I don't think that landscape orientation is software related.  But I can definitely see #2 being software.

    32GB, Wi-FI only.  built week 13, Foxconn (DM). Arris CM/Wireless Router/EMTA (Comcast)

     

    No dropouts.  I can replicate the "death grip," but I only lose one bar.  Even so, I have to cover a good part of the edge.  The router is in the basement and I had 3 bars in my 2nd floor bedroom.

     

    I understand it's not all about bars.  Speedtest numbers are consistent with my PC (I don't own any other Apple devices).  I can get the numbers to drop with the "grip."

     

    I am left-handed and I use my left hand to touch the screen; I hold the iPad with my right hand.  So, I'm less likely to inadvertently hold the unit in the "grip."

    How can you tell when and where it was manufactured? Mine is the 32g white wifi only and I'm not having any "dropouts", just a little slow and inconsistent loading web pages compared to the iPad 2.

    You can  tell where and when it's made by just reading the serial no.

     

    The first 2 digits indicate the factory (DM, DN etc).

     

    The 4th and 5th digits are the build week.

     

    So..

     

    DMx13xxxxx would  mean DM factory and build week 13.

    FYI - I have  alphas (HG) in the fourth and fifth positions in my SN.  Perhaps there is a decoder for alpha to numeric?

    I thought I would share my experience.

     

    I ran some tests using the speedtest app and got the following results:

     

    Location 1: Same Floor 10m From Router

    The New iPad: 8.00 Mbps

    iPhone 3GS: 15.17 Mbps

     

    Location 2: 1 Storey Up 25m From Router

    The New iPad: 3.00 Mbps

    iPhone 3GS: 14.50 Mbps

     

    I brought my iPad to the Apple Store and the Apple employee did a quick test by connecting to the Apple Store WiFi with my iPad and a iPad from the store and loaded apple.com on both of them to see if they loaded the site at the same speed. My iPad was a bit faster. He stated he could not load the speedtest app on the store's iPad. I had no back-up and was unprepared, so I politely thanked him for his time and left.

     

    I went home and performed the two tests again and took a photo of the results of the iPad vs. the iPhone 3GS. I brought these to the store along with a print out of a page from this thread. Apple agreed to replace my iPad but said that this would be the only time they would replace it due to a minor WiFi issue. I performed the tests again with the Replacement "The New iPad." Results below:

     

    Location 1: Same Floor 10m From Router

    Replacement "The New iPad": 17.24 Mbps

     

    Location 2: 1 Storey Up 25m From Router

    Replacement "The New iPad": 16.71 Mbps

    One way it could be software related is if software regulates the chip that decides how much power goes to the internnal antenna.  If the chip that regulates power to the antenna is not doing it's job because of software, your wi-fi signal might not be able to get the juice it needs to overcome reception issues.

     

    I don't think it's any different versus my wireless performance from my PC or Laptop NICS.  I get perfect reception right now throughout my house.  However, when I was experimenting with this issue, I reduced signal strength on my laptop and PC NICs via the power management features.  When I reduced them too far, I was exhibiting the same exact symptoms.  Even my laptop based on orientation was losing signal strength.

     

    The only difference between my IPAD and my laptop is I manually adusted power to my internal attena versus the IPAD which appears to do that autmatically via software according to that article.

    So the same exact software IOS 5.1 will be different from one iPad3 to anther iPad? If the hardware is not different or defective to some extent it should not matter. The software should interact same modle to same modle the same way unless something I one of the devices is different hardware wise.

    No two pieces of hardware are created equal IMO.  I posted in a previous post one example when I did dialer support.  The other example I can think of is when I built two identical PC's for a client.  They had the exact same parts down to the motherboard.  However, when I ran FPS tests on the graphics capabilities of both, one performed slightly better versus the other no matter what I did.

     

    Not saying this is the exact same issue but if the power being supplied is border line that could explain the variances even though the hardware is the same.

    I agree that no two pieces of hardware are exactly the same. In previous statements the are allowable tolerances in the manufacturing processes are the reason.. That being said the tolerances seem to have been exceeded in some cases as it has been pointed out that some iPad3's are good off the shelf and some are not. I understand your views on software but,  in this case I just can't see it as a fix, a band-aid possibly, but not a fix. Anyways there will be no proof so to say unless Apple steps forward with a reply but, many units that are being exchaned however with the wifi issue(s) for new units, the new units don't  seem to exibit the problem (at least in most cases) with the wifi. Oh well I'm going try another unit this weekend and see if I can get a good one as two of my friends manged to get during the initial release.

    Apple, just get serious....this is similar to the Iphone 4 Antenna issue. Took months until you admitted your product had a DESIGN FLAW (although there was no admission whatsoever.)

    Same here: the wi-fi problem with the new Ipad was so annoying, that was better to return it and keep using my Iphone instead.

    Hope you fix this problem soon so I can buy a new one.

    A claim can be contested by an single example to the contrary. 

     

    Examples, however plenty, can suggest a claim with certain amount of probility -- the more controlled the examples are, the more probable the suggested claim is correct.

     

    In your statement, you make a claim "tolerances seem to have been exceeded in some cases".  I'm having trouble giving this claim a high probability because you list one example and the example it self is a generalized statement that some have the issues while others do not.  There could be a handful of reasons why one person sees a degradation while another does not and there can be no relation or asumptions between them because they are different people in different environments and potentially even different connectivity routers.  Assuming the software glitch was exlusive to wireless-n routers, that would certain cause some people (those who have wireless-n) to have problems while those with another wireless technology to be fine.

     

    To use the varying responses of people as a claim "tollerances seem to have been exceeded in some cases" is a really far stretch.  I'm not claiming there are no hardware issues; I'm simply saying based on the evidence thus far on many people having issues connecting to wifi after upgrading to 5.1 (semi-controlled environments where same person, same wifi, same device, same location, etc. didn't have issues for many months before and all of a sudden started having issues with ios 5.1) is indicative, with resonable probability, there is a software issue with the 5.1 update which coincidentally is the software version released with the new iPads.  If you have any other details which could substantiate and increase the probability of a hardware issue, by all means share and the time you spend to do so is much appreciated as this collaboration we are going through now is how the problems will eventually be rooted and solved.

     

    For reference and benefit of others on the thread, I used this link where various people reported wifi issues on various iOS devices after applying the 5.1 update:
