Is there any way to change the IP address? I can't access some websites due to the problem. When I was with Telstra all I had to do was turn off my modem for 5 minutes then restart it and I'd have a new IP address, everywhere I check on the internet says the same thing. I even reset the modem by pressing the reset button and nothing happens. Would buying my own modem to use make it possible to change the IP address by turning it off then on after five minutes?
