    I haven't seen any reports of this, but at the same time I haven't done too much searching.

    Anyway, my Wifi is terribly slow when I do speed tests with the App speediest.net. Most of the time when I check it vs 3G, 3G wins. I know my network at least here at home isn't the problem, my Macbook Air is getting the proper speeds it should be and they are right next to one another. Anyone know what is going on?

    Thanks!

    Mine hasn't been slow, but I have noticed it causing a problem for the other devices on the wifi network at my house. The other device start getting speeds of 6 mbps, which forces me to have to reset my router and modem. This doesn't happen all the time, but a number of times when it's been connected it has.

    I checked wifi speeds on mine and my neighbors networks. They looked about right... Is it possible that you have a faulty wifi receiver(or whatever you call it) in your phone?

    I hope you figure it out! :confused:

    I'm not sure but with some of the problems we're having...I wouldn't be surprised. Trying to see if I hear anything else on this. Thanks for your replies.

    Just guessing, are you 100% sure you're attached to the correct network?

    My iphone 4S Wifi maxes out my broadband connection. My iphone 4 could not do this, would achieve maybe 75% of max at best.

    I have never been able to use that high of a percentage of my connection. I have a 25mb connection at home, with a newer Linksys router, and my wifi speeds only hit about 6mb even on my 4s.

    What security settings are you guys using? I use WPA2 Personal.

    I'm using a WNDR7000 router with WPA2-PSK on cable internet, supposedly a 15Mbps connection but generally seeing higher rates. Speedtest.net on my Macbook Air usually gives similar results to my iphone 4S.

    BTW, I'm trying to run the battery down all the way on my 4S, thus the relatively low battery level in case anyone is curious.

    I have no problem.

    I'm getting 18-20mbps down and up.

    Yup, pretty much exactly this. In my testing last night, on one of them my Ping was 1000+. Hope it works itself out, I guess we should give it a few days but it just seems like a hardware problem.

    You should also try different servers. I find it pathetic that some can only deliver information at .5-1mb while others cruise at 5+.

    Even though I already have, I didn't think it really mattered when connecting to Wifi. I'm talking Wifi, my 3G is fine.

    Just to be clear are people saying with the 4s that you can reach the maximum of your Internet speeds on wifi? I know with my 4 I can get around 23mb with my connection being 50mb. I know the wifi chip is not the same as a computer but can the 4s really match what your computer can get over wifi?

    I am talking about wifi. The servers do matter.

    Depends on if you are setup as wireless b/g/n.

    The point is you won't see wifi speeds in a speedtest any faster that the external server sends/receives. If it's the bottleneck then the test isn't testing your wifi speeds.

    Within the variability of individual speedtest runs I am seeing essentially the same results from the SpeedTest app on my iPhone4S as I see on my Macbook Air using speedtest.net

    BTW, my iPhone4S is attached to the 2.4GHz side of my WNDR3700 and my Macbook Air is attached to the 5GHz side. (dualband router)

    Both generally reach the stated bandwidth of my Internet connection.

    Reset your network settings on your iPhone. Reboot your WiFi router.

    I also have issues with my 4s compared to my 3g. My 4s is abysmal on my home network, but fast for 3g speeds. These tests are all on the same server and the phone is located in the same spot in my house.

    4s on home network | 4s over 3g | 3g on home network

    and that 4s over 3g speed is quite slow from what i've seen. I've been able to get up to 9Mbps download and near 3Mbps upload, depending on the server

    Doesn't work for me. I'm thinking my router settings my need a little adjusting. My 4s and 3g behaved the same with. I've just never bothered to mess with it.

    Thanks for the replies. So have you noticed an improvement on the wifi speeds on the 4s compared to the 4. I have seen good speeds on my 4 but it's never gotten to the max download speeds. I have a 2.4 ghz wifi n router. Is there any settings that could be tweaked on the router to increase the speed?

    Check those apple links I posted earlier. You'll have to sign in with your apple id on at least one of them, maybe both.
