I recently assembled a new computer, but the internet remains unreachable.
I recently assembled a new PC and encountered internet issues. It functioned well in the basement where I installed it, thanks to a stable connection. After moving it upstairs, connectivity problems arose. The internet would briefly connect for a minute before dropping completely, then restarting for another minute failed again (displaying "not Internet, secured"). Moving it back to the original location restored functionality. I've tried a TP-Link PCIe WiFi adapter, replaced PCI slots, performed a network reset with Windows, adjusted DNS settings, and even used an Ethernet cable—each attempt failed. My router isn’t blacklisted, so I’m still unsure what’s causing the problem.
verified if any IP conflicts exist within the network? Such as duplicate IPs assigned to devices, even after DHCP. This can occur if a device remains in standby mode without active network connection but retains its configuration, causing the router to reissue the IP address.
I recently tested this, Ethernet functions but WiFi remains faulty. Annoyingly, relying on Ethernet isn't a lasting fix since I can connect via cable to my room.
Review your router's documentation. You should be able to access the router interface and examine active connections for duplicate IP addresses. Verify there are no devices assigned static IPs within the DHCP range. On your new PC, launch an admin command prompt and enter "ipconfig all" (Wi-Fi enabled, connected). Check if the device is assigned a local IP address. You can also run "ipconfig /release" and then "ipconfig /renew" to confirm proper local IP assignment on the wireless connection. Make sure the Wi-Fi and DHCP settings are correctly configured, and review the router's DNS configuration.
I've verified for duplicate IP addresses and found none. The ipconfig command failed with an incomplete error message, but the ipconfig /renew returned a successful response. On my router's management page, I see my computer is the only device using the 5G band instead of the 2.4G band, which might be the problem. I'm unsure how to switch between bands when using Virgin Media and would appreciate your guidance. Also, I realized I forgot to run ipconfig/release before, but after doing so it still didn't work. It's definitely not about the band selection since I restarted the router and now it's connected to the 2.4G band, but it remains unstable. Updated September 18, 2023 by mark_anthony
I'm sorry, I should have included "ipconfig /all" in the instructions. It appears the device is receiving an IP address on the Wi-Fi adapter, which seems positive. If this were your situation, the first step would likely be to temporarily turn off the Windows firewall or any other firewall software running on the machine. Check if the firewall is preventing the connection due to a configuration error.
Following that, consider these additional commands: disconnect the wired Ethernet connection and then proceed with pinging the gateway. If you receive a response, try using nslookup to verify DNS resolution. You can enter a known website in the command line, such as "wired.com," to see if it resolves correctly. If nslookup fails, it may indicate DNS or firewall issues.
Once nslookup works, attempt to ping an external IP address like 8.8.8.8. If that succeeds, you can continue; otherwise, review your DNS and firewall settings.
Assuming the nslookup is operational, you can proceed to test connectivity on the 2.4G band—either by searching Wi-Fi settings or manually selecting the 2.4G network in the taskbar notification area.
