Connection through a switch without direct internet access (modem → switch → PC)
I purchased a quicker link with an included AVM case, so I handed over my old Fritz box to my parents. Because of Easter I don’t have any box at all. Nevertheless, I have a contract and here’s the issue: the old modem/router is linked to a switch, which connects to my computer and my roommate’s PC. It works fine there, but my computer can’t reach the internet. It’s stuck in network discovery mode, even though it’s connected without an active link. The IPconfig output shows: Ethernet adapter — connection DNS suffix — Intel® Ethernet Connection (2) B0-6E-BF-xx-xx-xx DHCP enabled. Autoconfiguration is on. Local IPv6 address is fe80::fc45:xxxx:xxxx:a247; IPv4 address (auto config): 169.254.162.71. Subnet mask 255.255.0.0, default gateway DHCPv6-IAID 45117xxx, DNS server fec0:0:0:ffff::1. Network setup is enabled via TCP/IP and the switch/PC1/PC2 are not online.
The exact model isn’t specified, but it appears to be either a standalone modem or a combined unit without a built-in router. It likely functions as a modem rather than providing routing capabilities, possibly operating in bridge mode instead of handling routing tasks. Without your confirmation, I can't be certain, but the setup suggests limited functionality beyond basic connectivity.
It's set to bridge mode due to the olf FritBox. Do you know how to adjust that?
I updated it back to Routermode and everything functioned properly! You didn’t expect bridge mode to be so influential.
The issue isn't the bridge mode itself, but rather how it interacts with routers. It's beneficial to place a router behind it. They typically provide only one external IP address, and if you request it, they usually fulfill your need. However, when you switch to bridge mode, you turn off the router and use just the modem. This leaves you in a situation where asking for an IP results in receiving it, but the modem stops forwarding any further requests, cutting off your internet access.
