That’s pretty cool!
Although that’s probably what op is actually asking for, I don’t think it’s a modem. It’s a router with an access point.
It does have SFP for a fibre connection and pcie and USB for you to potentially add a modem or whatever else you want.
I’m guessing OP is just looking for a wifi router? Otherwise we’d need to know what kind of modem they’re looking for, like Cellular? VDSL? HFC? Satellite? It depends on the internet connection. Different parts of the world need very different kit.
It does sound very strange. What kind of anti-China content would ever help a student’s application process? Most of the application documents are about things like English language competency, visa requirements and prior qualifications, not political opinions.
