> In some cases, swapping the modem could change your IP
Hopefully, there are no two routers, worldwide, that have IDENTICAL MAC-addresses -- that is the whole point about MAC-addresses.
So, a swap WILL give you a different MAC-address, and Shaw's DHCP-server WILL give you a different IP-address.
Note that Shaw's proxy-servers only handle "HTTP" traffic, not "secure-HTTP" traffic. So, if that web-site exclusively uses "secure-HTTP", the IP-address they receive will be your IP-address, not the IP-address of the Shaw proxy-server. Sigh.
Or, if you reconfigure your router to use "Passthrough" for one of your Ethernet ports, and connect your computer to that port, and you get a second IP-address from Shaw, your computer will obtain that second IP-address. Hopefully, that IP-address will not be "banned".
I can't open some websites since last week, that's why I am going to change IP address. I already swaped my router but still can't opening those websites. Have any solutions?
> I can't open some websites since last week.
What error-message do you get? What happens? What does not happen?
Have you tried "Passthrough", as I previously suggested?
Have you tried enabling Shaw's proxy-servers, as I previously suggested?
It shown on Chrome was "can't be reached". Those websites come from China, such as cn.aliyun.com; www.pospal.cn; etc...
I think my IP has banned by those websites for some reason.
I just control my router through "10.0.0.1", there is nothing I can do.
> It [is] shown on Chrome was "can't be reached".
For me, the "non-secure" web-site: http://www.pospal.cn "cannot be reached", but the "secure" web-site: https://www.pospal.cn is accessible. So, as I stated before, configuring to use Shaw's "proxy-server" for this web-site is not a bypass.
So, again, using Shaw's "proxy-server" will not help, for this web-site.
> I think my IP has banned by those websites for some reason.
I am guessing that the "Great Firewall of China" is blocking all HTTP-traffic (secure or non-secure) from your current IP-address.

I previously indicated that the Hitron cable-modem has a "Passthrough" capability, to give you a second IP-address, which, hopefully, is not blocked.
Which router do you have? Hitron? Shaw Gateway? Shaw BlueCurve? Shaw BlueCurve Total?
Or, you could use VPN to expose a different IP-address to those web-sites.
