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

I'm so grateful for this fix! Recently got a new NETGEAR AC1900 Nighthawk router, Just disabled QoS/WMM and now my Apple products are 100% faster on my home network! (iPhone 5S, iPad Air, MacBook Pro) Thanks Again!

I left the default setting with WMM on and it's faster than off on my side. My network stable and flow flawlessly.

UGGGG!  So I found where to change the Wmm/qos to off for my motorola router..but when I do it I get TXOP limit errors... It will say things like, the parameters must be between 1-15.  or must be in multiples of 32. Considering I dont know what any of this gibberish means and there are many boxes marked TXOP I am at a complete loss. It wont let me change the qos because of this.  HELP!!

My iPad2 suffers from the very same problems. It worked fine so far, that is, as far as I can figure out the problems started when iOS 7 was installed. All that has been suggested here, worked.......for 5 minutes only. Very frustrating and as a result this is the first... and the last iPad. My modem/router is a rather unknown Chinese ZTE H220N that came with my subscription. It works fine though and my iMac "sees" the full maximum of around 25 Mbps. continuously? No matter what the settings in WLAN are. The router stays, the iPad goes. Indeed, Apple should have adressed these malfunctions as soon as they appeared. Where I live, Holland, the iPad2 is still sold new, barely capable to cope with all the demands iOs7 insists. Is this how Apple wants to treat its customers?

I think there's a very good chance that you're experiencing a problem specific to Comcast.

Comcast tags the incoming packets in a way that breaks WMM. On certain routers (that don't strip those tags as they're coming in), this causes them to treat all traffic as low priority. Disabling WMM 'fixes' it, but also disables an important 802.11n feature.

If you've got DD-WRT on your router, you can 'patch' it in a way that strips those tags and allows WMM to be enabled:

I've had the issue of my iPad being extremely slow on my Wifi when none of my other devices are. I tried in vain to "turn off"qos. I thought I just couldn't do this on my AT&T Uverse router, so I bought a new one to use in conjunction.  I also couldn't turn it off there. Finally, a coworker explained to me that QOS is built into the Wireless-N specification.  All I had to do to fix this problem was change my Wireless Mode from 802.11b/g/n to 802.11 b/g in my router settings. If you don't pay to have a high download speeds, the g specification is fine. It can handle up to 54 mbps, according to something I read on the internet. I only pay for about 15 mpbs download, so g is plenty for general internet usage, including streaming video.  Also, I did reboot my router and iPad after I made the change. I'm not sure if that was necessary.  I hope this helps a few of you!

After reading all the posts I have finally located the WMM support on my dlink router. As soon as I shut the option on the router the speed on my iPad Air is back to 20 mb - 22 mob download and 5 mb upload. No more buffering when watching netflix.

I don't understand what's in ios 7.1 that broke it but all I have to say is it was a frustrating and disappointing week Apple. I have expected better from you, and not having to jump hoops to fix it on my end where obviously there is a software glitch with newest software.

It's sad to see a great company with such great products to walk this thin line with their customers. Come on Apple, live up to the high quality of products and customer service we pay so much premium for and confirm the bug, otherwise you are continuing to disappoint and upset a lot of your user base.

Thank you all of you for a great forum and support , which resolved my issue, again not thank to Apple unfortunately.

Concerned customer...

That's great for you but can you elaborate and let others know the steps taken to shut the option or simply let us know where to find the WMM support info and we can follow along on our own? Thank you.

My iPad 2 is getting only 3mb down on a 56mb connection. My iMac gets the full 56.

I have no WMM option on my Comcast Xfinity WiFi router. I've already tried switching from b/g to b, g, to b/g/n, none of the options have an effect on my speed.

How the **** do I fix this?

Sometimes on Comcast routers the problem can be fixed simply by powering off the router and powering it back on. If yours is the kind that has a battery backup built in, you'll have to disconnect that as well to actually power it down.

If that doesn't do it, look for a QoS setting. That's effectively the same as WMM.

I have Comcast as well, but ultimately the best solution was to purchase a much better router and use it rather than the piece of crap that they rent you. :-)

Good luck!

Wow... wish I had stumbled on this earlier.  I have an iPad2/Apple TV set up that I have been using in my classroom.  This year I started noticing connectivity issues and lag.  It was getting so bad that I stopped using the iPad for presentation for fear of the AirPlay connection failing.  Got around to replacing all of the components (including a new iPad Air) within the last few months, and was still having issues.  Sometimes, I couldn't even rely on the AirPlay option being available when I needed it - it was like the iPad and the Apple TV couldn't 'find' eachother.    Turned of WMM on the router, and suddenly, I'm back up to speed. 

This unfortunately does not fix my issue on a 4th Gen iPad. When I disable WMM on my Netgear N900 router, the only thing that happens is I go from 65 down on my PC to 25 down. iPad stays around 8 down with WMM off and on. I just lose speed on the PC by turning it off. Not sure where to go from here. This is a highly annoying issue as I pretty much use my iPad to watch YouTube, Twitch, Netflix, Prime Video, etc., so right now it's fairly useless to me.

Here is my situation and the troubleshooting I did, including tinkering with wmm/qos....iMac is blazing fast, iPads (2, air, mini) all much slower:

Thank you for the detailed testing across multiple platforms to confirm. I unfortunately believe that it is related to iOS 7 somehow. I have owned my iPad 4 for about 18 months now, and only in the last few months have I noticed the inability to watch 1080P videos from YouTube. I remember when I first got this thing it would fly through a 1080P video.

I'm with thebski here, I'm pretty sure it's iOS 7. I had no problem with WiFi before iOS 7. I'm positive my videos streamed a **** of a lot better, now they barely stream at all.
