Fixed my slow iPad Wi-Fi issue, here is what I found...

Great posts above. I haven't tried the QoS fix because I didn't see this thread until now, but I did have crazy slow Wi-Fi on my iPad2, now fixed, so thought I would share my experience incase helpful.

I was having horribly slow Wi-Fi speeds on my iPad2, despite a fast cable modem connection and a "N" generation Linksys wireless router (maybe 2-3 yrs old). Was achieving speeds of only 1.3Mbs -- slow enough that you couldn't watch YouTube videos. From hunting around on the web, I came across the suggestion to manually set the Wi-Fi router to the "G" standard (ie downgrade it from the faster "N" standard). Remarkably, I did it and it worked like a charm. I now get Wi-Fi speeds of about 12 or 13 Mbs, or 10x what I was getting before. Bizarre but true. It is an easy fix. And also I think the "G" standard is capable of 50Mbs so even though it is a slower and older standard, it is still way faster than anything you are likely to achieve as a home user.

Maybe changing the QoS setting also does the trick, and perhaps that is a better solution. But changing setting from N to G has done the trick for me. Good luck.

CM2010, you Rock! I just got an iPad2 & my download speed was averaging 0.80Mbps (Glacial). I disabled QoS in my Linksys Router & viola, the download speed is now averaging 13Mbps.

I was all set to spend hours troubleshooting. Luckily your post was the first result for my internet post. Thanks again.

Thanks for the helpful, detailed tips. I've been trying to diagnose or repair the lousy, erratic wifi performance on my iPAD1 and my iPAD2 for some time. I tired the network reset option, and it hasn't changed my results. I must be very close (3 to 5') to my Airport Extreme or Expresss (I have both) to get any performance at all. My iPhones and Macbooks work fine on wifi all over my condo. The iPADs are just very erratic, and often unusable if I'm not within a few feet of the router.

I have been trying to solve my slow connection speeds for months. I was just about ready to pursue a warranty replacement claim. I just found this post and it worked. My router won't allow me to turn off QoS and stay in N mode, so I have to keep in b+g mode. However with QoS mode off my iPad transfer rate went from .4 Mbps to 11Mbps. As far as this being a minor software glitch that Apple will fix quickly, I don't think so. I just upgraded to iOS5 and the problem wasn't resolved.

Thank you for this post, it saved me lots of hassle.

Been searching for weeks on various boards trying to figure out why my Ipad2 is so slow. I was about to have apple take this back for a replacement. After buying 2 top of the line routers one as a base and another as a bridge/repeater and the Ipad2 was still as slow as ever. Even had a neighbor who is network certified couldnt even find a reson why it was so slow. I was in the process of contacting apple again for the 3rd time to send a replacement when I stumbled across this forum. I went to the wireless set up tab on my netgear 9500 and disabled the WMM ( not the QOS ) as that is something totally different, and my Ipad2 now seems to be working alot faster. I will give it a week and see if this finally fixed this slow connectivity issue. Why apple has not addresed this is way beyond me... If they dont support QOS/WMM, then they should state that... Watching video and no issue so far... keep my fingers crossed.

Thank you CM2010. Just disabled WMM through the QOS tab on my Linksys WRT160N. Internet speeds are great on my 4S especially when streaming video from ESPN. Thanks again!

Amazing! I've been messing with this forever and your suggestion fixed the problem. My iPad connection to my Netgear WNR834B v2 was giving me a download speed of about 0.45Mb, and is now giving me 12+Mb. Thanks.

This is amazing and worked like a champ! Thank you so much for this suggestion of disabling QoS/WMM in the Gaming/Application settings for the Linksys router. I did not even have to reboot my router or ipad - it just started working great. My ipad2 was not only slow, it would drop off after being in sleep mode and even in the middle of doing stuff!! THANK YOU!!!

Hi all I'm having same probs as everyone but I've got a sky router any 1 no how to change the settings on this thanks

Thank you ! This is a life saver !!

Finding this post was a huge help! I am an IT engineer and, honestly, I just didn't devote the time to research the issue until now. I barely use my iPad2 because the wifi speeds at home are pitiful! 0.80/Mbps dl and 5.00/Mbps upload. That upload speed is what got me thinking... why would it be relatively good? Installing apps on my iPad2 was taking sometimes 1 hr or more! Ridiculous!

I changed my Linksys router to G-only and turned off QoS... BAM! DL speeds jumped to 25/Mbps! Huge difference. I do this stuff for a living and I never would have guessed an issue with the router. All laptops, smartphones, etc work great. I assumed it was something with my iPad2 like it was defective or an OS/firmware issue. I had pretty much given it to my wife as a dedicated Words w/ Friends toy. Now that it's fixed I am taking it back.

Thank you so much for posting this fix. As an added benefit I asked my kids to try their iTouch and they said it had never been so quick. And Apple, you suck for making all your products incompatible with something as insignificant as QoS. IMHO the front page of the docs should say "Warning! Turn off QoS or your download speed will be horrible." But no, instead you either let people suffer or they go blow wasted money on an Apple router which doesn't have QoS.

Thanks to keithfrommarietta for the detailed instructions on how to do this! I am the domestic IT expert at our house and that isn't saying much. I have only had my ipad2 for a few months and was furious to be having problems with something as basic as streaming youtube videos. After two calls with apple support my problem was not solved by upgrading to the latest ios or resetting my network settings.

Disabling WMM on my router instantly solved the problem! I have a Netgear N600 Wireless Dual Band Router. I found the option to disable it under the ADVANCED tab, then Setup, then QoS setup.

Glad to be of service! I too am shocked that Apple hasn't better addressed this yet, or at least offer detailed instructions on how to work around it. I know it's not a problem everywhere which might be why they haven't come up with a more complete solution, as I've been at friend's houses and checked their settings and found the QoS or WMM enabled, yet still get 15 Mbs+ on the download. The thing is, when your iPad crawls, this is a very effective fix for it. Cheers!

Having same issue with my iPad 2. Anyone knows where is the WMM/QoS setings in a LINKSYS Wireless-G Cable Gateway WCG200CC? Many thanks.

not surprisingly, Windstream washes their hands of the issue since it is the I-pad, not the internet connection. I have a Sagemcom 1704 Windstream Modem/Router, G series operating in Mixed mode. The Qos was NOT enabled; i went in and disabled the MMS (Advertising)based on earlier support community advice but that hasn't helped either. Laptop response is fine, this is the I-pad--and i see it mostly in the email download (Safari surfing is fine). Any further recommendations?
