Q: 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.

    Thank you, this was most helpful.  It worked like magic.  I now get 5.5mb download, which for our village is good.

    I had a similar issue with the Linksys E1500 and my iMac. The solution was to change the WPA2 Personal password and/or network name.

     

    The problem was that I gave my new router the same name/password as the old router, which then incorrectly assumed that the WiFi network password was a different type of encryption (old cached value) - not 100% sure, but something like this.

     

    Another tip: go into the modem settings, QoS and disable WWM. You can also test which band gets the best signal in your house. Some recommend 1, 3, 6, 11.

    I had the same problem.  Most people are saying that they are using the speedtest.net app.  If you use anything else, you will see the speed increases.  I think there is a problem with their app.

    Disabling QoS on my D-Link DIR-601 didn't resolve the issue. Still downloading at .20 mbps.

    HI

    just I just off the phone with my ISP Rogers Cable in Canada. I was challenging customer service to have the same download speed for mu iPad as my windows 8 laptop. I was told to use the G5 network connection, versus the 2.4. Ie if your network name is network1, then network1 is the 2.4 and the network1 5G is the 5G.  Using the speedtest.net app my download over wireless went from 24  to 60 - 70 kb after this change. This only works if you can se the 5G network from your device. I believe it works on iPhone 5 and above and all iPads. No guarantees

    Hi,

    The maximum download speed I get from my iPad mini retina is almost half that of my iPhone and macbook. My ISP gives me 60mbps internet, however i only get around 30-40 on my macbook air and iPhone 5c and this tends to fluctuate to lows of 10. But on my iPad I only get around 10-15 average this can go up to 40 but rarely does.

    I know my wi-fi router is the bottleneck as always get 60mbps download when on ethernet. It is a stock CBN cable modem router literally in the same room as where i use my iPad, and I also live in a building with 15 other routers from the same ISP running on 2.4ghz. Could it be interference or compatibility issue with the router and the iPad?

     

    All software has been updated.

     

    Any help would be thoroughly appreciated

    Thanks for the suggestion. I logged into my new BT Home Hub 5. and followed the instructions below. Now I am getting 30Mb/s on both the iPad 2 and on my iMac, whereas I was only getting 3-5Mb/s on the iPad before.

     

    I have problems connecting 5GHz and dual band devices wirelessly to the BT Home Hub 4 or Hub 5

     

    The BT Home Hub 4 and Hub 5 are dual band with two wireless frequencies for devices to connect to: 2.4GHz and 5GHz. On both Hubs, the default setting has the same network name (or SSID) for both the 2.4GHz and 5GHz bands. Connecting a typical 5GHz-capable device to this single SSID will automatically connect the device to both the 2.4 and 5Ghz frequency at the same time.

    However, not all dual band devices behave the same way and some device software does not cope well with a single SSID for both frequencies.

    As a result:

    • the device may not connect wirelessly to the Hub
    • it may not connect to 5GHz frequency even in the same room
    • the wireless connection might be intermittent
    • the wireless connection might be very slow

    Devices where there are known to be problems include:

    • Some Apple devices including iPhone 5 and Apple TV
    • some Android smartphones
    • Xbox

    For some devices you can solve this problem by having different network names (SSIDs) for the 2.4GHz and the 5GHz bands. To set this up, follow these steps:

    1. Open your web browser on a device connected to the Hub and go to bthomehub.home. This will open the Hub Manager
    2. Click on Advanced Settings and enter your Hub admin password when prompted. Unless you've changed it, you'll find the default Hub password on the Hub settings card
    3. Click on Continue to Advanced Settings
    4. Click on Wireless
    5. Click on 5GHz
    6. Change 'Sync with 2.4 Ghz' to No
    7. Change the 'Wireless SSID' to a new name (we recommend just adding '5GHz' to the end of the existing SSID name so you'll know which one is which)
    8. Click Apply to save the changes

    After a few minutes you should see two BT Home Hub SSIDs in the list of networks on your device. All of your devices will still automatically connect to the original SSID name, which will be the 2.4GHz.

    If you have existing dual band devices you want to connect to 5GHz only, you'll need to connect them to the 5GHz SSID that you've renamed.

    Even though wireless speeds at 5GHz can be significantly faster than 2.4GHz, the range of a 5GHz connection is not as good. As a result, you may need your device closer to your Hub (than you'd need to when using the 2.4GHz SSID) to get the best performance possible.

    Thank you, I just disabled WMM (I really have no idea what that is) and, based on a different suggestion, disabled "20/40 MHZ devices." And it seems to have worked - my iPhone 6 is connecting to my Netgear router WiFi and staying connected. Fingers crossed.

    I have the same slow iPad WiFi problem, it appeared a few months ago.

    Does anyone have an idea how to disable QoS on a Microtik (Router OS) router?

    I have the same problem - terrible iPad WiFi speed, all other devices in my house blaze.

    Does anyone have an idea how to shut off QoS on a Microtik (Router OS) router?

    Not sure what router you're using but I had the same issue when I received my BT hub.

     

    BT flick between 2.4ghz and 5ghz networks in the default settings and it seems this doesn't suit the Ipad!

     

    I logged in to the advanced settings on the router - stopped the sync between the two networks and renamed them with 2.4 and 5ghz at the end giving individual passwords for each.

     

    I connected my ipad to the 5ghz network and bingo! Now getting over 50 download and 10 upload wheres as before they were almost nothing!

     

    Hope this helps!

     

    Ben

    Keith! You've been SO helpful, TYVM. I'm ashamed that I must actually ASK you this—showing my ignorance, nevertheles... the part of your reply where you say;

    ... You need to log into your router to manage it's settings. If you don't know how to do this, usually you can go into your wireless settings &amp; look for the IP address of your default gateway (typically something like 192.168.1.1 or 192.168.1.254, etc). Then open your browser &amp; type that IP into the address and hit enter. You'll either be presented with the admin page for your router or a login for its user name &amp;f setting available to change. If it's a recent router, you should have to the option to switch from mixed mode (G/N) to just N. You should also see either the QoS or MMS setting that you can disable.

     

    All this having been said, this will only fix your problem while at home. If resetting your iPad's network settings didn't help, I suggest going into an Apple store for service. They will suggest two things, first, to completely restore your iPad. This, of course, you could try at home but it doesn't guarantee to fix the problem and it is a bit of a pain. If you try this, note that you want to do a "clean" install of your iPad when you reconnect it (i.e. don't restore it from a backup in iTunes) or you will just be reloading the corrupted settings from before. The second thing they will suggest is just to swap out your iPad for a new one, which may resolve the problem. Thankfully, I didn't have to go that route, as the reset of the network settings has completely resolved my throughput problems. I've since tested my iPad on several networks and haven't experienced any slowness on them.

     

    Hope this helps!

    I DID NOT MEAN to actually POST my question like THAT!!!!

    i Realize it makes no sense, I just wasn't nearly done...and I don't even know HOW I actually posted it. I was TRYING to delete and just start over.

    thanks for your patience with me Keith...just-- disregard that post entirely,

    I'll try again, anew. (SEE how ignorant I am? Lol)
