    I too have this problem but the reason for it is because of the aluminum backing, the 3G version doesn't have a problem because it has that black plastic at the top.

    Cmon apple, get your heads out of the sand!
    I paid almost a grand for the 64gb wifi/3G iPad and am seriously thinking of getting a refund. It's just not worth it. Being a computer networking professional for over 25 years, I thought this would be a great tool, but if
    net(is not)working, then what's the point???? The fact repeated time and again that all various wifi devices are working fine EXCEPT the iPad points to the obvious problem!

    I was also hoping for the same thing...better WiFi with the 3G but that's not the case at all. Many folks here, including yours truly have identical WiFi issues with their 3G iPads. The extra "window" doesn't make any difference. The plastic "window" at the top of the 3G model is where the cell and GPS antennas are located. Per these photos...

    iPad WiFi/3G Antennas: http://i43.tinypic.com/11snn9j.png

    The WiFi antenna is in the exact same place for both models. Both the 3G and WiFi only models utilize the plastic Apple "window" in the center of the back of the iPad.

    The website IFixIt.com has a teardown of both models...

    As mentioned earlier I did manage to get my iPad 3G WiFi to perform very well (at least at home) after some router and iPad tweaking. More here...

    I have now logged my WiFi problem with Apple by ringing 0844 209 0611 in the UK.
    The Apple guy said he had not come across this WiFi problem, so I would encourage all contributors to this and other threads who have connection problems to log them with Apple and get an incident number.

    I stressed to the support guy that if my iPhone works in the wild at WiFi hotspots, then my iPad should work too – and without having to fiddle with various settings.

    Do not trust the replacement iPad units from Apple! If you have WiFi performance issues, I recommend returning the device, rather than getting a replacement ... or make sure you test the device repeatedly in the Apple store including taking the device just outside the store to see what network performance is like slightly distant from the multitude of access points in the Apple store.

    I believe that the "replacement" iPads are, in fact, new iPads and are not refurbished units.

    Sorry, this whole story doesn't seem to ring true.


    Sorry, it is true. All of the replacement iPads that were brought out were in generic brown boxes. I asked the Apple employee explicitly if these were refurbished units. His answer "they likely are."

    The fact that every one of the replacement units showed very poor network latency, 10 times worse than those on the showroom. The replacement iPads also showed significantly slower than the showroom iPads.

    I spent 3 hours at the Apple store. This was by no means an exhaustive, scientific test. It was my attempt to make sure I got a good unit. I took the time to share the information here, so that others might benefit.

    OK. I did perform a controlled experiment to measure the relative iPad Wi-fi signal rate compared to my (late 2006) MBP (Macbook Pro 17"). Here is the setup (all Apple products):

    1. My router is an Airport Extreme Base Station (I think 2008 model). Radio Mode was set to "5Ghz Only" to prevent any possible interference from other devices. It is 4 meters away from the iPad and MBP with direct-line-of-sight (no obstacles between them). Security set to WPA2, channel automatic (no choice here), antenna set to 100%. Rest: default router values. The router shows 2 Wi-fi clients (MBP & iPad).

    2. My iPad (64-3G) and my MBP are sitting side-by-side having exactly the same distance to the router.

    3. Run Airport utility. Pick the router. Click "Manual" setup. Go to "Advanced" option. Click on "Logs & Statistics". Click on "Wireless Clients" tab. 2 graph lines representing 2 devices show up.

    4. Here is the first measurement:
    MBP Rate = 300, signal=full bars (MBP status bar)
    iPad Rate = 39, signal=full bars (iPad status bar)

    My understanding is that the rate is the maximum theoretical transfer speed this router can achieve. Please correct me if I am wrong. So, my first question is "relatively speaking, how come an iPad (using exactly the same wi-fi set-up) is 7.5 times slower than a 3.5 yo MBP?"

    5. Second experiment was about changing the wi-fi "Radio Mode" from 5GHz to "2.4 GHz Only". Channel set to auto. Everything else the same. Results:

    MBP Rate = 130, signal=full bars
    iPad Rate = 39, signal=full bars

    Question is " why on earth does the iPad rate stay the same whereas MBP drops more than half?"

    6. Second part was to repeat the same tests in a room about 15 meters away. My MBP was able to maintain the full bars. iPad started to fluctuate between 1 and 3 bars, mostly sitting on 1 bar and loosing the connection.

    My early conclusion from these tests is that my iPad has both transfer speed and range issues over a Wi-fi connection unless iPads have been designed this way.

    I already talked to Apple and created a service ticket for this. The Apple rep was very polite and thanked me for conducting a controlled and isolated test. His only suggestion was to reset the iPad unit and repeat the same tests (which I did with the same results).

    I am also wondering whether someone from this forum (who has the same set-up) would repeat the tests to see whether this is a one-off situation (my iPad) or common to all/some iPads? Thanks.

    Hope this helps.

    Do you suspect that the "replacement" IPADs are simply returned items reboxed?

    If, as I suspect, only 1-3% of the IPADs sold have this issue, the reuse of returned IPADs could be 50+% having this issue.

    All I can say is that I would keep returning them until you find one that doesn't exhibit the wife (sic of course I meant wifi) connectivity problem.

    This thread nearly scared me off from buying one.

    So far so good, but if mine quits connecting you can bet it is going back.

    @iHo I read elsewhere on the Apple support site a suggestion that we disable the 5Gz frequency of any router used by the iPad. That seems to correlate with your finding that the relative performance of the iPad was better when you were on the 2.4 GHz band.

    I'm getting connection issues and wavering signal strength. Simply turning WiFi off and on seems to resolve the problem in most situations, and for quite a while, so that's an acceptable workaround for me while Apple work on the problem. I've been contacted by Engineering so I know they are are leaving no stone unturned in their investigation.

    Yes, I believe so.

    The Apple store genius was clearly embarrassed and surprised by how easy the issue was to reproduce. We used the dlsreports.com iPhone latency and speed test site. it's not perfect, but was fine as a basic tool. The results were stark and obviously different between the replacement iPads and those on the showroom. After 3+ hours of trying and failing to find a replacement iPad that did not have the issue in the stock of units the Apple store had, I returned mine to Best Buy.

    I'll definitely get another one, but only once the dust settles and the issue is clearly resolved.

    I have a 64G + 3G Unit. Same issues with signal coming and going.
    I tried changing wireless to WPA2 = No signal benefit...comes and goes
    I tried changing wireless mode to G only = No benefit...comes and goes
    Then I started changing the wireless channels and ended up on channel 2 (2.417 Ghz) = Rock solid.

    Frustrating thing is that all other wireless in the house (phones, PC labtop, PC desktop, WII, XBox, DS) are all rock solid. IPAD signal would drift 20 ft away or even 2 inches away from the router. Even without moving it. My only conclusion is that it's sensitive to other devices in the house. At least now it's rock solid.....in the house.

    I have a 32gb wifi 3g ipad. Wifi reception on my ipad will cut in and out. Meanwhile I am streaming hi def to my tv and have full signal strength.

    If I turn wifi off in settings and then back on I have full signal strength and wifi speed is good. Then it will start to drop down to 1 bar and lose signal.

    Maybe it's a power issue. I hope it's a software issue. But there is a problem somewhere or this thread would not have so many posts.

    My experience has been that my iPad shows less networks than other devices I have. It even shows less than my iPhone does... Very disappointing. I would think twice about buying an iPad until this issue is fixed.

    I've had it with mine. I've been having more issues lately, or just getting less tolerant of them, and called AppleCare. They are replacing it. I'll keep my toes and fingers crossed that the replacement behaves better...

    I found out a tidbit that might be new: The 'patch' is coming in the new IOS4 update. Apparently, according to the agent that I talked to, it will not be available separately. A ray of sunshine, potentially, was that he said that the update would ship the end of this month. That's not correct (unless it changed) because what I heard was that the IOS4 update wouldn't be out for the iPad until September (Fall). Did the ship date change? With the details coming rapid fire fashion from the WWDC keynote yesterday, I don't know...

    Oh, I took some teasing over Steve having connectivity issues with the iPhone 4 yesterday... The heathens...

    That really was embarrassing. I'd hate to be his network guy! It was pretty funny when Steve asked for suggestions and someone shouted out "Verizon!". They were on WiFi, not 3G so a bit unfair to AT&T, but the message was loud and clear.

    Thanks for the update...iOS4 makes sense. Last I heard it was due out in the fall as well. But maybe they're comfortable releasing it at about the same time as the iPhone 4 (which uses the same OS) . One can only hope.

    Best of luck with your new iPad. Mine has been humming along just fine (after the various tweaks to it and my network) so it is possible.
