Hi. My name is***** you for your question. Connect the iPhone to your main wireless
network first before opening the Safari browser on the phone.
On the phone, go to Settings>>Wi-fi. Make sure wireless is on.
Tap the name of your new wireless network and enter the wifi password.
When successfully connected you'll see a checkmark next to the network name.
Open Safari and you should be able to surf the internet.
If you're still having an issue, can you connect your PC to the router with a network cable
and get an internet connection? If you can, I can remote in to the PC and get this sorted.
Certainly. If you can get the PC on the internet using a network cable to the router I can take care of this.
