iPhone/iPad slower internet speed

[Guibs]

Just want to know if its a setting I am missing. I have the speedtest app on both my iPhone et iPad. even 3 feet away from the router, direct sight, I cannot get my full download speed (60mbps).

Wired connection gets the full speed. I also have a laptop that can acheive top speed even further away so it seems limited to the iphone/ipad/iPod production.

I used the same SSID for both 2.4 and 5ghz but when looking at the logs, I see both ipad and iphone connected to the 5GHZ band (which is expected when so close to the router). Still I'm lucky if I acheive anything north of 30mbps in download speed.

Is there a setting or something else I'm missing that would allow me to get full internet speed on these devices?

running Merlin latest build (376.45). Never notice that problem before but before today, my download speed was cap at 30mb but I upgraded my internet speed today. I did a full reset of the router (factory reset and reconfiguraiton) to be sure it was not remember some setting on the old internet speed.

like I said, laptop on wireless (wireless adapter shows 450mbps wifi speed with the router) gets to 60mbps. Just apple products that seems that they can get there.

Radio transmit power on those low powered devices just sucks so you can't really help it.

Try older firmwares; 41, 42 and 43.

In my experience, firmwares 44 and 45 give me worst distance and speed do to changes Asus has made in latest firmware and new Broadcom drivers.

I've noticed the same issue using an Iphone 4 and the AC56U ( fw .5656).

On your iPhone/iPad/iPod, go to Settings>General>Reset Network Settings. Type in your PIN, and then confirm your resetting Network Settings. Your device will reboot. Reconnect to your router, and it should be much faster Doing this clears out your DNS cache, temporary file settings, and lots of other system cleaning. This should make your iOS device connect to the network faster.

Be advised that you should also make sure you have the latest iOS version on you iOS device, this will also make a difference. In addition, the latest iPads and iPhone 5S have wifi speeds up to 150 mbps, whereas the iPhone 4 has a max wifi speed of 50 mbps.

Thanks for the information, I will give it a try.

After some thinkering last night, I was able to get close to 60mbps in download on my iphone 5s but my ipad 3 wasn,'t getting there yet but since its wifi is limited and also the fact, as mentionned by theveterans it might just be the device itself.

thanks again for the suggestion, I'll try reseting the DNS routes on my idevices and see if it improves.

Well doing the reset on the ipad network didn't do the trick. Tested with my laptop and it was still doing strong with great signal, internet download speed at 62mbps with my local wifi evaluated at 300mbps on the main floor (router in basement).

then as I was looking at the settings, I've notice that my 5ghz band channel bandwidth was set at 80mhz (the setting was at auto). So force the channel bandwidth to 40mhz and my internet speed connection got instantly a lot more stable (no drops).

On my iphone I can get around 45mbps with both the iphone and ipads without cutoffs. I guess the router thought 80mhz was good enough without interference to work but it was wrong. 40mhz seems way more stable.

Just thought I'd post results in case someone drops by and have a similar issue.

Depends on what version of iOS device you're working with...

iPad1/iPad2/iPad3 - single stream dual band narrow channels - 65Mbps max

iPhone 4/4s, iPod Touch 4th Gen - single stream/single band narrow channels - 65Mbps max

iPhone 5/5c/5s, iPad 4, iPad Mini, iPod Touch 5th gen - single stream/dual band - narrow in 2.4GHz, Wide in 5Ghz - 65/130 Mbps max

iPad Air, iPad Mini Retina - 2 stream, dual band - 144Mbps (narrow channel) in 2.4GHz, 300Mbps wide channels in 5GHz.

On an iPad Mini Retina in 5GHz, I've seen as high as 117Mbps down, 78Mbps up on an Aruba 802.11n 3 stream AP in a enterprise environment - 1GB on the AP, with 10GB WAN side

iPhone5 - 87Mbs downlink, 53Mbps uplink on the same AP

The latest firmwares 44 and 45, have a wonky 5ghz settings. A wrong combination will give you worse results. Try older firmware.

Real world with light interference you should see about half the link speed? So you need the 135/150 Mbps wide band 5 GHz link to saturate a 60 Mbps WAN?

I assume you are talking about link rates as 1x 802.11N's max link rate is 65 or 72.2 Mbps. EDIT: Sorry, of course you are talking link rates. Your benchmarks are a bit under half the 300 Mbps link too.

So an iPad 3 isn't going to see better than a bit over 30 Mbps actual.

Edit: I notice you state the max link rates for anything older than the iPad Air as using a 800 instead of a 400 ns GI. Is this intentional, can the iPad 4 generation really not link at 72.2/150 Mbps? I didn't have the ability to check link rates yet when I had an iPad 3 but I have seen the max 300 Mbps you state on the Air.

fastest I've seen on iPhone 5 - 5GHz, Wide Channels, N900 class Aruba AP, 1GB to the AP, 10GB Level3 backhaul (carrier grade with MPLS and good QOS) - 75.10Mbps down, 68.04Mbps up - this is the same AP that I provided the numbers for iPadMini Retina (117Mbps down, 78Mbps)

I assume you are talking about link rates as 1x 802.11N's max link rate is 65 or 72.2 Mbps. EDIT: Sorry, of course you are talking link rates. Your benchmarks are a bit under half the 300 Mbps link too.

So an iPad 3 isn't going to see better than a bit over 30 Mbps actual.

Basically - the chipset in the iPad3 is single stream (MCS7) and narrow channels only in both bands 0 - IIRC the chipset is capable of supporting wide channels, but the driver doesn't enable it, perhaps to save power?

Edit: I notice you state the max link rates for anything older than the iPad Air as using a 800 instead of a 400 ns GI.

Short GI is optional on the client side, even if enabled on the AP (which most do) - I won't say for absolute, but iPhone 4S/iPad 3 and earlier, I've not seen short GI used.

I have seen short GI used in the newer devices for 5GHz for wide channels with the limited sample set of devices I have, but they seem to fall back to 800ms GI in 2.4GHz - this likely is a design decision by the engineer writing the driver configs at Apple.

Think you might be right. Problem came back although better than before. Connected my iPad to the 2.4ghz only for testing and I can get up to 40mbps in download so it seems to be a 5ghz issue. Might revert back in firmware to see if it fixes it.
