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.

Thanks, Keith, your fix worked for me as well. I have a theory; after 2 years of connecting to wifi in perhaps 30 other locations, the machine just bogs down from all the logins and settings and sessions outside of the home network. I didn't check speeds, I just went to a graphic intensive site and it loaded in a blink vs. staring at the screen for 20 seconds for it to load. Thanks again!

Again, it feels like this thread has been going on forever and Apple still haven't fixed this problem yet. I bought a new-generation iPad (model MP2F2B/A) and I think I've been having the same problem. We switched to a new BT Homehub 5 from a Homehub 3 a week or so after I bought the iPad because there was something flaky with the wi-fi- anything without a wired connection to the router kept losing internet. I also think we use an ADSL too, though what kind I don't know. However since then my iPad frequently gets incredibly poor speeds: while everything else gets a good (for copper cable) 14up/1down, my iPad will usually struggle to get more than 0.5up and often nothing down at all: streaming apps like Netflix and Youtube will just say there's flat-out no connection and ordinary websites take forever to load, if they load at all before the connection timing out. Running speed tests shows that it either initially connects at the top speed, but drops down precipitously a few seconds later, or just never gets higher than 1.5 Mbps. Resetting the iPad or deleting cached data sometimes helps but never for long. I'm quite frustrated, as I just shelled out more than £300 for this tablet and I can't even use it in my own home anymore. I'm not very good with computers (which is why I buy Apple products 😉) so I don't really know how to fix this, even with the advice in this thread. I just thought adding another instance of this happening, with a new iPad and a new router, might help build a bigger picture of how to fix this permanently in future.

I was having issues with slowness on my 16GB iPad and my WRT300N v1.1 router. I was only getting about 2-3MB. I noticed that turning the mode from mixed to G only fixed the problem. But since the whole point of an N router is the N, I tried your method. After disabling the WMM Support under the QoS tab (with the mode back in Mixed), I was able to go back to enjoying N band and my full 10MB download speed. Great find!

wow! It fixed my slow speeds too. I am back in mix mode.

My router is WRT160N ver 1. with firmware 1.02.2. I went to "Applications and Gaming" under my router settings and then QoS and disabled. and changed my router to MIX mode. works extremely good.

I also tried N only mode and works amazing fast. for now I am using mix mode for other G clients.

Thank you very much JJBECKSTROM. May be I will call Apple and let them know.

You guys do realize though that the 802.11N spec says you must support QOS/WMM in order to do 802.11N rates. You guys might be taking your N router and making into a A/B/G router.

You can check this fairly easily with a wireless sniffer (wireshark) or connect a Macbook to the same network and option+click the AirPort Menu Extra (the radar bars). See what rate you are connecting at.

ok from whatever I read, Apple extreme routers dont support QoS.


"You guys might be taking your N router and making into a A/B/G router."

I dont think so, I put my router into "N only" mode and then turned off QoS, I could connect Macbook (which is N) and iPad (which is N too) but not my iPhone 3GS (which is G). And the speed was 20mbps on both macbook and iPad, which is what I get on my router., but I moved back to G only mode and turned on QoS.
