    No. The warranty does not give you the right to return the product.

    Definitely have this issue as well, I didn't realize it was around the time of the upgrade, but it makes perfect sense. I was able to stream youtube videos just fine within the youtube app for the first week I had the iPad, and then after the update it was worthless. I have not been able to stream 1 complete video since then. Speed test apps show between 8-12 mb download and 3mb upload. it seems to be strictly related to video streaming over wifi, but maybe it is happening throughout the device, and just showing the most via youtube. I have also tried the youtube webpage, and it is just as bad as the app. However, if I turn off hd via the webpage it streams near instant. Obviously this is not acceptable. I bought the iPad for this type of usage, and I'm not getting it. Quite tempted to return it and get my money back.

    I have a linksys wireless-g router wrtsl54gs, no issues at all with any of my laptops/desktops, wired/wireless, i've rebooted the router, the ipad, restored the ipad, and messed with dns for the **** of it (seriously? dns?)

    Well, I'm going to take it to my local Apple Store tomorrow and see what I can do. I've purchased a lot of equipment from them, and I would hope they could offer some service here.

    As far as I am concerned, my iPad is defective.

    The problem with the iPad being slow has nothing to do with your routers. It's an issue with the driver running the wifi network card in your iPad. This may affect only certain people since there may be different revisions of the wireless chipset out there. Since Apple ship millions of these iPads, it would be impossible for them to have the same wireless chipset on every iPad. I can't believe this wasn't caught in their in-house testing of iOS 4.2.1. But this may because they don't use all the routers in their test labs that consumers around the world use. But they definitely changed something in the driver since in version 3.2 everything worked perfect.

    Anyways, for the time being, as a work-around, try tips from the following websites:

    I have been as exasperated with the IOS 4.2 problem as the rest of the posts. I tried essentially every fix here, with my Belkn B/G router. Nothing worked for more than a few minutes.

    Except one thing...after all of the other fixes were tried, I simply went and changed my router channel select from "Automatic" to "Channel 2".

    For the last 24 hrs, I have been working with no disconnects, and previously I was getting one disconnect every minute or two. Now it seems stable.

    Try it and see if it works for you. My wild guess is that something changed in the wireless receiver driver iniOS 4.2 or something causing the iPad to be more susceptible to disconnects from interference or something. For me, before this fix, even moving the iPad within 2" of the router didn't improve anything, so it was not a signal strength thing.



    I had previous tried a lot of the other things people suggested and changed all of them back to original settings.

    If you convince them, they'll replace it.

    I have two of the first release iPads (March). After clobbering both of our iPhones with the OS 4.2 upgrade and still regretting it I decided to upgrade mine and wait on my wife's. Smart move on my part as I am back to less than 56k modem speeds while my wife's runs upwards of 6mb downloads. Mine stalls on accessing any webpage and speed tests show 10k to 56k at best. Side by side speed tests and just safari web access is unbelievably slow or nonexistent on mine while her's just races along. Imagine the trouble I would be in if I had up??? (down) graded her's instead of mine?
    PLEASE Apple send us a fix!
    I will video these two side by side and post them on YouTube if it will help!

    Ok, forget my previous message. Broken again. After almost exactly 24 hrs is now having problems again. Sigh. At least the drop out took a lot longer to happen again.

    If the product doesn't work, he totally has the right to return it to be fixde or replaced for one that works. If they're unable to provide one that works, then they will have to give him his money back.

    At the beginning of this thread I found this posts too, and tried this. It seems to be OK for me, but after 6 hours the problem has returned. Sorry.
    I fully agree with those who wrote that the problem is not in our routers, but in iPad new WiFi driver.
    Returned back to 3.2.2. Everything OK.

    I am having the same probs and went to the Genius bar for advice. Needless
    to say IPad worked brill. I have done complete restore etc etc etc. The guy at Apple told me that it must be a router wifi prob and to disconnect everything else using network reboot etc and it should be ok. He also told me that they were not aware of any such problems with wifi after update - can you believe it! Showed him my speedtest results on IPad and IPhone which are completely different. Anyway came home and did as he told me and voila everything exactly the same - IPad terribly slow and virtually no upload speed at all. He said I could not go back to earlier version of IOS. Sorry this sounds a bit mixed up I am a complete novice.

    Certainly in the UK, consumer protection laws come into play in this circumstance. If a product is not "fit for purpose" and can be assessed as such by an independent third party, then you can pretty much return it regardless of warranty and even terms and conditions.
