Coaxial to ADSL/VDSL

[TheJaffaMaster]

So my friend gave me his Asus DSL-AC68U to replace my ISP provided modem router that uses a coaxial cable. The Asus modem router uses DSL.

 

Is there a way I can convert coaxial into DSL for the Asus router? Alternatively, is there a way to convert RJ45 ethernet into DSL for the Asus router (where I use the ISP provided router to convert the coax into ethernet)?

 

Thanks in advance!

Neither are going to happen with consumer-grade hardware. But you can still use the ISP-provided modem and that Asus. Just plug it with an Ethernet cable from LAN to LAN. It'll work, but you need to re-do some settings, namely disable DHCP in the Asus.

A standard RJ45 cable doesn't seem to fit in the connector (see attached photo). Is it possible to get an adapter for it? Thanks a million!

No, no. I really did mean from LAN to LAN. The yellow ports. You can pick whichever you want, but it's customary to use LAN1 for WAN (Wide-Area Network).

You're right, an RJ-45 is never going to fit in the RJ-11 (or RJ-12 for that matter) port. That's by design. The DSL signal is analog whereas Ethernet is digital. That's what a modem (MOdulator-DEModulator) is for. It turns DSL and other analog data transmissions such as Dial-up and ISDN into digital transmissions and back. What I'm suggesting is to plug an Ethernet cable from the LAN port in the ISP-provided DOCSIS modem into the LAN port in the Asus and not use the modem-functionality in the Asus at all, just the router in it and the wireless access point.

 

RJ11-RJ45 adapters do exist and are even abundant but they're used for FAX machines and telephones.

Just tried it, works perfectly! Thanks a million!
