iPhone 4 not connecting to wi-fi but 3GS works fine?

[james-bailey]

I have both a 3GS and an iPhone 4 the household and just recently, the iPhone 4 doesnt seem to be able to browse the internet using our wifi network.

All laptops and the 3gs connect perfectly using DHCP but the iPhone 4 seems to have issues.

After going into Wi-Fi Networks > Clicking the network in question, then DHCP on the phones, the iPhone 4 displays a complete different set of IP & Subnet mask numbers, compared to the 3gs

Please can anyone shed any light on why this may be happening?

My friend who also has an iPhone 4 struggles to use our wi-fi network here

Cheers

James

Bump.. ;-)

could be the firewall on your router. what type of security are you using, if any? did you try manually entering your network settings? ip, dns, etc?

 

[james-bailey]

The router is a Netgear DG8343 v4.

Im not aware of using an security on the router to be honest.

What I have done though, is enter the details into the iPhone 4 manually in the static IP part (using the 3GS for reference) and changing the last part of the IP Address to a random number and now its working great.

What does this suggest now its working static but not DHCP?

Cheers
