Identify network problems Resolve Ethernet complications
Hi, I see you're dealing with a tricky setup after your recent upgrade. It sounds like the new routers aren't connecting properly. You've already checked the cables and tried multiple connections, which suggests the problem isn’t with the physical wiring. Since the old router worked smoothly, it might be related to configuration or power settings. Have you verified that both devices are powered on and that the Ethernet ports are enabled in their settings? Also, ensure the 30m cable is securely connected and not damaged. If you're still having trouble accessing the admin panel, try restarting the router and checking for firmware updates. Let me know what you find!
The 30-meter cable might cause issues and could be unidirectional. It's likely that Wi-Fi functions, but there may be a password on the router. Try resetting the device and verifying LAN settings. The attached images aren't included—do you mean links to the store? I’ve had similar problems with new routers; older models often work better. Would you like me to suggest a replacement?
These consumer units simplify troubleshooting: Internet → Modem → Router → Switch → Your devices. ISPs often bundle a modem and router together, sometimes combining them in a single router with a 4-port switch. I've noticed routers that don't have DHCP enabled by default for some reason. If you locate the intended broadcast network, assign a static IP and check if you can log into the WebUI. Otherwise, consider resetting the router or testing with another device. Have you tried a different computer? Does wireless connectivity function? Can you reach the WebUI from there?
The WebUI displays active connections and shows which ports are engaged. When a device connects, it reports the specific port details in the interface.
The switch connections on the new device appear to be inactive, though some testing can be performed. You indicated you've tried using various cables, suggesting the issue may not be with the cables themselves but rather a verification step. Are all cables purchased and undamaged, with unmodified ends? Your laptop's USB C dock is equipped with an Ethernet port; connecting it to the router yields consistent results compared to the desktop setup. To confirm cable integrity, you could link the desktop directly to the dock and manually assign IP addresses to both Ethernet interfaces. If pinging works successfully, the cables should be in good condition. Most network interfaces from the past ten years support auto-sensing, eliminating the need for a specific crossover cable. Should the desktop connect to the router without issues, it likely receives an IP address starting with 192 or 169. If it receives 169, the DHCP server isn't assigning valid addresses. The fact that wireless works implies the router is handling DHCP independently of the switch ports. If all else checks out but the switch ports remain unresponsive, consider returning the router for replacement, as internal switch failures are common in home setups.
I used the cable included with the router and another one I purchased recently. Yes, this was the method I followed to link the router to the laptop, but it isn't being recognized on either device. I noted that a dock might be faulty as well, which adds another consideration. That's quite intriguing. I plan to test it tonight and observe the outcome. Additionally, I've noticed I don't require an internet connection for my experiments, so I'll disconnect the routers from the RJ11 cable, relocate them to my office, and conduct further tests. I intend to share the findings tomorrow evening or the following day. Appreciate your thorough response!
Haha yeah, I'm assuming he meant RJ45 RJ11 is usually for telephones and is 2 pairs RJ45 for networking and is 4 pairs
RJ11 cables serve ADSL-style links, linking the router to an RJ11 cable while internal routing uses RJ46 cables.
