    Im having problems with my iphone wifi conection. I use a wireless router Dlink DI-524 here at home and I noticet that the wifi conection on my iPhone were really slow, but the conection on other PCs on the wifi network wew just fine.

    So I pinged my iPhone to see what happens, and the latency was extremely high and unstable for a wifi LAN. Look what ive got:

    I tried to change the settings under the tab "Wireless Performance" on my router and nothing resolved. So I noticed that when I connect my iPhone over an ad-hoc wifi connection i got the correct speed.

    I have your very same problem.... I notice very poor speed performance on my iphone while using wireless. I've it connected to my home or office setup, at home I have an Airport Extreme while at office an Airport Express, both with N-protocol enabled but with G support. The macs in my house or my office have great speed, but the iPhone is very poor. I've done some speed test on the iPhone and the best I could achive was 60 Kb/s while the Mac could go around 600Kb/s. Also using the Airport Utility I've noticed that the max connection rate I have on the iPhone is 27 Mbit which drops down to 1 Mbit while using it...

    What do you mean when you try to use an ad-hoc wi-fi connection?!?

    Edit: I figured it out the ad-hoc thing. I created one ad-hoc network on the iMac and connect the iphone to it. The pings went blazingly fast like in your case. If I try to reconnect the iPhone to the Airport router the pings go down. Is definatly an issue when connecting to wireless routers.

    Data rate at 50byte/minute

    My data rate drops to 50 Bytes/minute, I noticed, that there are some more (weak) wi-fi endpoints in my neighbourhood, if more than 3 or 4 are up, then the data rate decreases. In the early morning when there are not so many endpoints running, ipod is working better. Typically 90% of pings are lost.

    I already connected my PC via cable to the internet, so that I am one wi-fi endpoint down.

    It has nothing to do with my wireless setup as all other devices are working fine, except the ipod.

    This bug may be connected with the fact, that the YouTube application is not working under any circumstances. I'm not missing YouTube, so I don't care.

    Safari sometimes works, sometimes, pages stop loading in the middle of the page. If I then reload the page, it is completed rather fast, so it seems, that Safari also has a problem with timeouts.

    Anybody an idea? I'm willing to jailbreak the ipod, if someone has a fix for all these issues.

    Ive noticed that sometimes even if the ping is high the download rate is fine. But never is stable or like at a computer. Im quite sure that there is an issue with the wifi of the iPhone, or its a system to save battery power, because wifi consumes a lot of power.

    My iPhone is jailbroken and the problem is the same. So... :/

    My iPhone is jailbroken and unlocked too. So I decided to try to restore to original 1.1.4, and then use iLibery+ to jailbroke, activate and use the Wifi/Edge repair mode.

    Well, my ping are still high, but I've noticed a faster wifi response in the device, specifically when using YouTube, Safari and Installer (it downloaded 5 Mb of BSD Subsystem in a zap!).

    You should give it a go! ;)

    I seem to be having a somewhat similar problem (although I am not familiar with pinging!)

    I have tested my (locked to O2) iphone on testmyiphone.com.

    My Macbook gives me 6.4 MBPS download speed through my bt homehub.

    I tested my phone and consistently got about 0.11 to 0.19 MBPS download speed.

    I tested 3G and was getting between 0.58MBPS and 0.88MBPS.

    so far so similar to everyone elses problems.

    However at the same time I was checking my wifes iphone (both are 3G mine is 16GB hers 8GB). Her phone consistently gives speeds on 3G and wifi of twice mine. I ran the tests at the same time.

    Is this normal or is my phone playing up? I hope someone can advise

    Thanks
