Yes and maybe

If your computer can handle a USB ethernet adapter then that should work.

Canadian Amazon site but this should be available on the US site too:UGREEN Ethernet Adapter USB 2.0 to 10 100 Network RJ...

There should be one that support gigabit too, but you probably don't need that

Probably don't.
Thankees, dk.

why not wifi?

If the wifi router fails, I have no way to connect to it (do I?), gogolita

isn't router and modem all combined now?

If there is more than one network connected to it, it's probably a router. If it's transmitting digital signals over an analog medium then it's probably a modem. Whether it's both usually depends on the kind of Internet service that's being provided.

WiFi doesn't factor into it even though WiFi device has become synonymous with "router"

Educate me then. I has a box stuck to my wall (Blu Tac). It grabs the wifi signal that the hotel sends us (Duo Hotel Guest) and then sends it out again, password protected, as "Squeaks Wifi" fur my laptop, 2 PC towers (both faulty), cellfurn, laptop, printer (also faulty), Smart TV, Roku TV (tv2), Firestick and Google Dot smart speaker thingy. What I got?

I furgot Mrs. Squeaks cellfurn and a desk "landline" style furn. The desk furn is loop through and used to feed my PC tower via RJ45. Now I has no direct connection to the "box on the wall" in the case of calamity.

I don't know what you have. I've never heard of a device quite like that. Is it something the hotel provided or something you bought yourself? (It doesn't really matter what it's called; I was just commending on Gogo's comment about routers and modems).

if you're on hotel wifi, wouldn't you just need to tap into their wifi singnal? i wasn't aware they allowed cable connectivity through the walls and such

most devices have built-in wifi nowadays

i don't ge the point of an additional password on a public wifi, which is also very insecure to begin with

The hotel doesn't give cabling permission, but their wifi signal is open to all residents. I have no doubt some super sleuth could hack into my devices. The "Travel Router" (it says on the box) password protects the devices from the main signal. Makes the public network into a private one.AC750 Wireless Travel Router

The desk phone, with its RJ45 pass through socket, is less than a foot away from my laptop (but the laptop has neither an RJ45 nor a directly available USB socket).

That's a cool looking thing

I ordered the adapter, dkronfeld. $7:51 at Walmart.
Delivers to me on Thursday. Thanks fur the help.
