2022-11-19 Next hardware to poke around in: Cab.Link CLS-D4E2WX1 router
The earlier Ethernet over Cable modem/router I poked at didn't come alone, from the same source I also got a Cab.Link CLS-D4E2WX1 cable modem/router. Doing a search for it finds actual listings for trying to order them wholesale: Buy Wholesale China 7400-eoc Slave Modem, Separate Tv And Ethernet From One Cable, 4 Ethernet Ports Output & 7400-eoc Slave Modem at USD 127 | Global Sources and Eoc Male Slave 4 Ethernet Port With Wifi - Buy Eoc Esclavo Product on Alibaba.com. Both listings call it an EOC slave. Given the terminology I expected EOC master devices to exist as well and I soon found out those exist and can be pricey. So I'm not going to spend money on this subject, but I may be interested in recycling an EOC master unit. The unit has one external wifi antenna, 4 ethernet ports, external power supply 12V and 9 leds. The cable connection is via 2 female F connectors with one labeled 'Cable' and one labeled 'TV'. I do notice the case has a lot of ventilation holes. On the underside is a label with the manufacturer name, model name, a default equipment management IP 10.10.1.250, a Wireless Network Name 'wifi' and the EOC and Wifi Mac addresses as numbers and barcodes, and the serial number as number and barcode. The unit has four little rubber feet (full LRF support) and two of those are hiding screws to open the unit. On switching the Cab.Link router on I indeed see a wifi network appear with the name 'wifi' which on connecting gives me an IPv4 address in the 192.168.1.x range with the default gateway 192.168.1.1.The Cab.Link router has a web interface listening on port 80. It directly asks for http authorization but using admin/admin for username and password gets me right in. Up until now I haven't found any reference to PLC or EOC in the webinterface. The Cab.Link also has a telnet server running on port 23. It greets me with an OpenWRT banner but the first few attempts at finding username/password do not let me in:$ telnet 192.168.1.1 Trying 192.168.1.1... Connected to 192.168.1.1. Escape character is '^]'.
