Retrieve ISP details from the router settings.
I need your ISP login details from your router so you can update it yourself. Unfortunately, they don’t share their credentials publicly and often reset them after setup. For your Linksys WRT54g-TM, you can try connecting the old router’s LAN port to a Wi-Fi port on your PC and use tools like Wireshark to capture traffic. This might reveal some network information or help you identify the ISP settings. Let me know what you find! Thanks.
What ISP are you connected to? What kind of link do you have (DOCSIS, GPON, DSL)? Is there any authentication method such as 802.1X? Usually your modem provides a public IPv4 address to your router, giving you full control over it. The ISP typically doesn’t alter anything on the router. It’s usually straightforward to reset the router password—have you tried that?
In some countries' ISPs restrict access tightly, making it hard to obtain the necessary data to operate independently. Even though you've shared some details, we still need more specifics. We require precise router models—both current and replacement. I’m unclear about what you meant by your story. Also, the type of internet connection matters, along with the ISP name (for those familiar). The country context is important too. Have you already attempted this yourself? Because it’s especially frustrating when trying to assist after seeing “Yeah, I’ve done that already.” If you’re unsure about any of these points, consult someone or contact the ISP. And remember, providing more information makes it easier for others to help.
My ISP is extremely limited, so I’m not sure anyone here would be familiar with it—but it’s definitely a big issue. I’m located in Lebanon. I’ve attempted: routersploit, setting up an Ethernet tap to capture data over the ISP cable (not entirely confident about the method), using Wireshark directly on the router’s wan port, and even tried swapping the router with another one just to test.
Check the router's documentation for login details. To determine your IP type, use an online service or ping a known IP to see if it returns a public or CGNAT address.
