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

I believe the iPad may have a issue if the router's QoS (Quality of Service) is enabled. I have a Linksys WRT300N router and when I disabled the QoS my download speed went from ~500Kbps to ~13000Kbps. This QoS setting does is not affecting my iPhone and iPod devices, only the iPad.

I have not experienced any signal issues, so I don't know if this will resolve those issues. I have informed Apple of my findings. QoS is a common feature on many routers, so if you are experiencing Wi-Fi issues please disable QoS in your router and let everybody know if this fixes your problem. Please report back your routers make/model and where to find the QoS setting.

If your were experiencing signal issues and after applying this patch resolves those issues please let everybody know by responding to this thread.

Ok I have an ipad 2 running ios7 on xfinity gateway modem router with 25mb/sec speed. When I do a speed test on the pad it is not even getting 1 mb. It is super annoying. Anyway, has anyone had success with running ipad 2 on an xfinity gateway modem router? I am not seeing the option to shut off WMM and QoS in the router control panel. I also tried shutting off Bluetooth on the pad. I have reset the pad's network settings, also restored to factory settings. Something has got to give. My HP laptop is getting close to 25mb/ sec when I speed test it, but it is sitting right next to the router. Even when I take the pad right next to the router I might get 1mb. Any help out there? Please!

Hi there, I contacted an apple adviser who asked me to back up my iPad to iTunes by cable, then restore factory settings. Then I had to set up the iPad as new, once I was able to verify the wifi was working as quickly as expected I could then plug the device back in to iTunes and restore the content from my previous backup. All in all 1 hour but working fine now. Thanks to all for your help.

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...

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.
