Issue occurs exclusively with the LAN connection cable.
Today I connected my laptop to the LAN cable as before, but websites refused to load. I attempted a factory reset on the router, changed the cable, and tried everything else, yet the issue persisted. Clearing the DNS cache didn’t help either. Checking the task manager revealed an odd local IP address that I wasn’t sure how to fix. Once I switched to Wi-Fi, everything functioned properly, which was reassuring at first. However, my need for a fast gigabit connection for work—since files reside on another PC in the network—became urgent. I assumed the problem was consistent across all devices, so I brought another laptop in for testing and it worked just fine. This led me to suspect the issue was specific to my laptop when using Ethernet. I can search online, but I’m stuck opening sites like Facebook or YouTube, while speedtest.net and League of Legends fail. Notably, some games connect over Wi-Fi, yet Ethernet connections are corrupted. Can someone assist me in resolving this without reinstalling Windows? My Razer Blade 15 (mid 2019, base model, 9750h, RX2060) is the machine in question.
Tested another cable? 169.254.* is the reserved area for IPv4, indicating it isn't receiving a response from DHCP. The screenshot shows an IPv6 equivalent. This suggests no DHCP reply, likely due to a faulty network port or cable. To confirm, set a static IP—your screenshots would display something like 192.168.1.100 with gateway 192.168.1.1 and subnet mask 255.255.255.0. DNS server also points to 192.168.1.1.
Thanks! It’s confusing why my laptop’s Ethernet doesn’t set up automatically anymore. Now it works, but I had to manually configure the IP and DNS on both the router and the laptop, and even then the router didn’t recognize the device. Still, it functions now—lol.
Well at least it works! So that tells us theres something wrong with DHCP on your computer and its not making the proper request. If you feel like trying to fix it when you're bored id check that the 'DHCP Client' service is running under services. I assume it is since WiFi has been working. Try disabling the Windows Firewall (if DHCP works after that then reset Windows Defender Firewall back to default) Reset the TCP/IP stack https://iihelp.iinet.net.au/resetting_tcp/ip_to_default Uninstall the device through Device Manager (Uninstall driver and tick box to remove software) and try reinstalling it.
I attempted that earlier and now it keeps changing to an odd IP address whenever I try it. It seems like I should stick with how it is right now. Perhaps a Windows update will fix this later.
