iPhone 4S speedtest.net results horrible, even on wifi

So I've been bumming out thinking my AT&T HSPA+ speeds were just horrible. And they may be. But I noticed in doing my tests with the speediest.net app that no matter what data network I'm on, 3G or Wifi, I get bad speeds. Especially compared to what I see other people posting in the forums.

I just did a test, and got the best speeds I've ever really gotten. At home, my wifi is connected to a 25Mbps cable modem. My Macbook Pro runs the test at speedtest.net and gets a result of 35Mbps down and 3.12Mbps up. Yet on my iPhone 4S, it tells me I get 3.27Mbps down/2.34Mbs up. On 3G, however, I never see over 1.5Mbps down and 1Mbps up.

So I'm not happy with speeds I'm seeing anywhere. Yes, my AT&T plan says it was the DataPro for 4S, so I think it is correct. And as mentioned, speeds on wifi suck too, so maybe it's my phone? What should I do?
 
You should be able to get speeds in excess of 20Mbps on wifi, I'm able to see that on my network -- I get nearly identical Speedtest results on my 4S as on my Macbook Air. I see ~20Mbps on a 15Mbps rated cable ISP connection.

Try resetting network settings, rebooting the router, etc. I don't know that there's a definitive specific cause/fix.
 
I was having crappy speeds on my iphone 4 via wifi too. This is what I did to solve the problem. I did a reset network setting on my iphone. Next I completely powered it off. Then I went to my wifi router, and set the 2.4ghz n channel to 6. I had it set at 1 but speeds were poor. I rebooted both my modem and router. After they came back up, I turned my iphone back on, selected the wifi router, entered password and voila, my speeds on wifi are 20 to 30Mbs depending on time of day. Powering completely off clears a lot of the issues, as opposed to a warm reboot.
 
You might want to try a different network speed test - I had issues with speedtest.net app as it was showing a hang on wifi and gave horrendous 3G speeds. It drove me crazy thinking something was wrong with both my wifi router and 3G service.

Maybe try the FCC Test app?
 
Check Setting->Location Services->Speed Test. If it is not ON, SpeedTest probably picks default server which may be far away from your current location. Also compare with SpeedTest results from a laptop/macbook.
 
Thank you for the suggestions all. I'll have to do the router work later, as I don't want to kill my VPN connection in the middle of my work day. Though honestly, my bigger concern is that my 3G speeds are so terrible. I was expecting an increase, even if slight, when getting the 4S vs my 4, since it support's AT&T's faster network rates, but I'm not happy with basic DSL speeds here. And I just can't decide if I need to return the phone, or what.

And I'll try out another app shortly. I was just doing the speediest.net one because it seems to be what everyone else in the forums was using. I thought it was the gold standard :)
 
Just ran the speedtest.net app on 3G in Detroit area and got 4.54 down and 1.22 up. I'm on a 4S - ATT

I just ran the test on my iPhone 4S. I was downloading at the time, but my iPhone was still able to pull 20/25.

My home wifi speeds get really slow once in a while, and I just reboot the router D-Link DIR-665 I think the model is, and it goes fast again.

I am on the iPhone 4 but my work wifi just got me at 4.87 down and 8.15 up. I wish my road runner at home had that up speed.

Seems my 3G has really slowed down in the past couple of weeks too. I have been getting 2 Down and 1 up recently. I used to be really fast, I wonder if it's all the new iPhones in the Albany NY area.
 
I guess if it was just my wifi giving my slow speeds, I'd agree that maybe it was something in my router or home internet. But I'm seeing the same thing on other wifi networks. And my biggest concern is my 3g (4g depending on who you talk to) speeds. Now I know when the world series is going on 7 miles down the road from me, I shouldn't expect 5Mbps. But I do expect that on off peak times I should be able to get better than 1.5Mbps, at least ONCE in the 8 days I've owned this 4S.
 
35Mbps and that's on my Verizon network :) 4G LTE baby! I don't use Wi-Fi to slow, luckily you guys have Wi Fi though, better than 3Mbps isn't it lol
 
Both of these speed tests in downtown Seattle

I was using the speedtest.net app and thought my results were not great for 3G...no higher than 3.65 download speed.

Just downloaded the FCC app. Download speed is averaging in the 5.5 Mbps area. Who knows....

I have found that using a Apple Airport for wifi results in bad speeds on the iPhone and especially playing YouTube videos on the phone. I had the wireless G one and bought the newer dual channel wireless N one too. Both run slow. Hooked up the default wireless G (dose not do N) verizon router and it is about twice as fast and reaches about twice the distance. Wtf.
 
My Air saw 36Mbps and my iPhone saw 35Mbps so yeah something is wrong. Please realize that the 4S cannot see 5.8GHz N-wireless while your laptop can. Maybe it's using G-wireless.
 
Sorry I should have changed it Mbps. Here's the easier to read result.

well I just tested with the FCC app and I get 7.32Mbps down/1.29Mbps up on AT&T 3G and 18Mbps on my Charter cable connected wifi at home.

I guess my problem is just with the speediest.net app then.
 
I just tried the FCC app... I got horrible results compared to Speedtest.Net

I am in the DC/VA/MD area and I have not seen speeds like others report for 3G.

Anyone know if ATT and others are throttling or throttling these apps?
 
Very slow speeds even on WiFi -- Me TOO!

I came here to complain about the exact same problem. Speedtest.net is showing download speeds of 1-2Mbps even on WiFi. Other devices show 30+Mbps on the same WiFi Connection.

The crazy thing is my uploads speeds are in the 7Mbps range. I have no other apps running and performed a hard reboot without improvement. I am starting to think there is an issue with the phone.
 
Just tried FCC app, getting similar results to Speedtest.net app: ~19Mbps down / 3-4Mbps up on wifi, 4-5Mbps down / 1.5 Mbps up on AT&T 3G (four bars). Computer on same wifi gets similar results (within 5% or so). Using a WNDR3700 router on cable internet (rated at 15Mbps down, 3Mbps up but typically shows better performance).
