Slow, Unreliable Wi-Fi Plaguing Some iPhone 3GS Units? | Gadget ....
Apple - Support - Discussions - iPhone 3GS Wi-FI speeds slow and ...

That was a loooong post! It is clear since the 3GS came out that there is an issue with Wi-Fi signal consistency and stability. I have experience this myself. I am confident Apple knows this now and will discover the problem and include a fix in the next software update. Until then we do our best.

I have the exact same issue. Very poor range for wifi networks, funny signal strength(sometimes a few feet from the router it shows 1 bar) and most annoyingly the very max dl speed i can get is 3Mbit. The same test on my macbook right next to the iphone 3GS shows 7Mbit. Whats up apple? Will I bring it back to the O2 store?

I have a new iPhone 3GS and a 1st gen iTouch. In numerous tests, the iTouch is about 4 times faster than the 3GS from exactly the same location at exactly the same time. My wifi router is a new 500Gb time capsule.

An example of the latest results:
++++++ Down Up
iTouch 4579 1254
3GS 1363 160

It can't be a range issue. I can stand right next to the router and get the lowest on the strength meter

I have the same issue with my iPhone 3Gs. I placed my wife's 3G next to my 3Gs and did a speed test. Needless to say, the 3Gs was dreadfully slower then the 3G. I called Apple tech and they had me do a network reset on the iPhone, after I did that, it was extremely fast, then it slowed down again after a few weeks. This went on for about 2 months until the trick no longer worked. I called Apple tech back up and they said I needed a new phone. So I went to an Apple store and they gave me a new phone. I then asked to test it. So we put the new phone next to the Apple store tech's phone and the new 3Gs was very slow compared to the tech's phone. The tech then got two new phones and they were slow as well. I asked the tech what kind of phone he had and sure enough, it was a 3G. He then said, "oh well, that's just how the phone works". So, I said no way and asked to talk to the manager. The manager then talked to his lead Genius guy. He said that it was "just the app that you are downloading". He actually said the developers program in each app how fast it can be downloaded!! I looked at my wife and she looked at me with complete unbelief that this guy actually thought we would believe it. We we decided that it was not worth arguing about because it was obviously a phone issue. So I left with a new phone.

Two weeks later I was getting sick of the slow connection again, so I called Apple tech support again. The tech did not know about the issue, but I told him to look at this forum. He was amazed, but he said he really could not do anything i had not already tried. So he set me up with an appointment at a different Apple Store.

Not sure what will come of it. I guess just more "Hey, your just a stupid customer that will believe anything, so it's not the phone, it's sun spots. Sun spots are causing your phone to be slow"!!!

Känner du någon som har en icke jailbreakad telefon som kan testa i din miljö?
