My micro-sim finally arrived yesterday and my iPhone 4 is now up and running! Well mostly.
Internet works fine at work over wifi, and it works fine over 3G. However at home the internet mostly doesn't work, except occasionally it works very briefly and then stops again. But it's not a wifi problem, the wifi icon is stable and doesn't disappear when the internet cuts out.
The laptops and games consoles in the house are all connecting to the internet without problem. And I had an iPhone 3G before this one, and it worked fine with the home wifi. My network hasn't changed.
Is there a setting in the iPhone I'm missing? Remember it works fine with wifi at work. At home I have a WAG310G wireless gateway.
Any help much appreciated!



is there a real world disadvantage using the slower protocol, or are broadband speeds still slower than 11b (and still the bottle neck)? I don't do any file transfers over wifi or anything like that, it's just internet (and printer).
