Weird question, I know. My apartment comes with a modern/router combo that, for whatever reason, does not have an Ethernet port. So a friend advised me to purchase a modem, then connect it via coax cable to my apartment's modem/router, then connect that to my PC via cat5. I did so, but the Ethernet connection on my PC shows no Internet. Is this possible to set up? Is there a software related step I'm missing to complete the connections?

Call your ISP, they can tell you if your modem is supported, and they will need to allow it to connect. It will be possible if they allow it.

Wow that should've been obvious, don't know how I didn't think of that. I called, they said it's not possible as it's not in the contract with the property. Thanks!

Yeah in my experience most ISPs will not allow this without paying for two accounts. You may be able to get them to provide a different model modem/router, you are likely already paying a rental fee for the one you have. Otherwise they can give you a list of the types they accept and you’re just going to have to buy one to sub in. Unfortunately the combo models tend to be on the pricey side.

If you're in Europe, you can try arguing they are in violation of the EU open internet regulation, but it's unlikely to get you anywhere if you're not in the green-marked countries of the map below: https://fsfe.org/activities/routers/routers.en.html

How are you supposed to connect your computer to the modem/router if there's no RJ45 port?

[–] [email protected] 2 points 1 year ago

Probably has WiFi only, especially if it's a landlord provided special deal with the ISP.

I bought a secondary modem, so my signal flow goes kinda like:

ISP -> Modem/router combo (installed by my apartment) -> Coax cable -> secondary modem I purchased myself -> cat5 cable -> PC

You can get a USB wifi adapter for your PC to connect it to the internet.

It's not an issue with the PC being unable to connect to Wi-Fi, it's that the Wi-Fi speeds are relatively slow and inconsistent. According to Ookla speed tests, there have been times where I get download speeds of 120 Mbps and up, times where I get less than 10, and times where I get between 10 and 25. I'm hoping by Ethernet connections that I'll be able to get more stable and maybe better speeds.

Ethernet only helps if there is interference or distance causing these issues.

For a desktop pc distance won't change.

Interference comes in many forms. Other WiFi devices, Bluetooth devices (especially if the PC uses the same antenna for WiFi and Bluetooth), weather, microwaves, washing machines, dishwashers and anything powered by electricity that moves/rotates.

If your low speed coincides with these issues ethernet will help. Ethernet will also help with total speed, if WiFi is the limiting factor. Such as your fibre line provides 200mbps, but with limits the access to 120mpbs.

If your low speed doesn't coincide with a WiFi interference. It could be due to the internet supplied by your isp. You many need to contact them to run diagnostics on the line. You can check the speed if your able to log on to your routers web page, the router should have a website that is a series of numbers and a different user name and password to access this when your are connected to it's WiFi network.

Back in the bad-old-days of having a shitty provider in student housing, I had a similar situation, and solved by making a box-of-faraday with a carboard box and tinfoil. Popped their crap modem inside, put my slightly-less-crap modem next to it, and ran my functional CAT5 (yeah, it was a while ago) out of the box. The tinfoil creates a nice interference-free zone, where nothing but your own two devices exist.

Of course, this was also before my phone had wifi, so it has it's downsides, unless you want to add a third accesspoint outside the box.

What's the model and brand of that modem/router? That might give clues as to what it is and what workarounds are available to you
