How can I set manually the IP Address for wifi?
- Hit the hard menu button on your phone and then choose Settings.
- From there, browse to the Wireless controls section and then choose Wi-Fi Settings
- Whilst in the Wi-Fi Settings section, push the hard menu button again and select Advanced.
- Press Use static IP to put a check in the box and then enter the network settings as per your own network.
If you’re not sure what your settings are, and assuming you’re using Windows:
- Open a command prompt by clicking Start, then Run
- Type in
cmdand hit Enter
- Type the line
ipconfig -alland hit Enter, the relevant details should be listed there.
Just make sure you use a different number for IP address on your phone than is shown on your PC!
If you control the network, you may be able to configure your DHCP server to always assign the same IP for your phone's MAC address. This has the advantage of working even if you (for example) do a factory reset of the phone, or otherwise revert the wifi settings.
My Linksys E2000 router supports this via a button labelled "DHCP Reservation" on the Basic setup screen, and any host-based DHCP server would allow this as well.
