The computer connects to the network, but the internet is down.

Why can my Windows XP PC connect to the router by cable but still show “server not found” in the browser, and how do I fix it?

Your network card is probably fine; the thread points to a DNS or proxy configuration problem, not missing internet drivers. If `ping` to an IP works but domain names do not, set the DNS servers manually and remove any wrong entry like `192.168.0.1`; use known DNS servers such as `8.8.8.8` and `8.8.4.4` (or `194.204.159.1` and `194.205.152.34`) [#13870753][#13872161][#13876692] Also make sure the browser is set to “no proxy” and check the `hosts` file plus firewall/antivirus settings for anything blocking name resolution [#13876854][#13876892] If it still does not work, reset the TCP/IP stack, remove and reinstall the network card, and check for malware because the machine was found to have threats [#13873421][#13877823][#13881054]

    Hi.
    I have a problem with the Internet. Well, I have a computer connected to the router by cable. The computer detects this network and connects to it, but when I try to enter the browser (I tried in firefox and opera) it says that the server was not found. The router and cable are 100% functional, because when I connected the computer with the laptop, the connection was good. And my question is, do I have any internet drivers or have I configured the network wrong?

    I have windows xp

    Thank you for any advice and best regards.

    1. Start -> run -> type "cmd" and press ENTER
    2. In the "black box" type "ipconfig / all" and press ENTER
    3. Show us a screenshot of this window (screen).

    Since you are getting the correct address from your router, you most likely have a DNS problem.
    In that black pane, do
    Code: Bash
    Log in, to see the code
    and then
    Code: Bash
    Log in, to see the code

    Both addresses are Wirtualna Polska (such a grandfather portal).
    From what I can see you don't have normal DNS, but give a dump of executing these two commands first.

    If you forgot about it (the first command will not work, and the second one will work), you can enter the network connection settings and enter DNS addresses in the "hard" TCP configuration.
    Examples of Google DNS are:
    8.8.8.8
    8.8.4.4

    PS
    Are the correct DNS addresses entered in the router configuration?

    Maybe some AV or FW is blocking your access to the net - DNS IP is a DNS proxy on the router and it should work, but you can always check as above if it resolves IP per domain correctly.

    And another PC connected to this network has internet access?
    Maybe your router doesn't have access to the network at all ...

    Who is the internet service provider?

    The router is operational, it was bought in June. The internet provider is Timplus.
    There were 2 laptops connected to it with a cable and the internet worked without problems on both of them.
    When I play with my brother via LAN, we both have a cable connected to the router (I am a computer, my brother is a laptop). And we don't have any connection problems.

    The network works, there is not only the Internet - I can see that ping (tracert) works, but not after the domain address (names instead of letters).
    From this I conclude DNS problems.

    Disable and enable the network connection on the PC.
    Is the pool of available IP addresses sometimes not full in DHCP? -> It is best to restart the router.

    Then give the effect of the commands:

    Code: Bash
    Log in, to see the code


    What is this provider?

    As additional DNS, you can add DNS from Tepsy:
    194.204.159.1
    194.205.152.34
    (because of excess in this case "head does not hurt").

    I think resetting the router will not do anything, because I tried to do so that I unplugged the cable from the router and connected it to the modem, and the internet did not work anyway.

    I disconnected the modem and router for over 10 minutes (to be sure), but it still didn't work.
    It seems to me that I have bad drivers, or not updated, because this computer is old and when I entered the local connection properties, later configurations and in the driver, it wrote that the driver version is 2.66.0.290 (I attach the screen), and on the laptop the version driver is 10.35.0.0 (I think you can clearly see the differences between these versions). I tried to install some drivers (nwm or good versions) mainly realtek, but it's very possible that I installed the wrong one, if you know what drivers are needed, give the links. I will be grateful for your help.

    Besides - you "ping" the Internet, only the name is not important to you.
    I'm still saying it's a DNS problem.
    You did not provide screenshots of the commands from your colleague's posts bogiebog (# 14) and mine (# 15).
    I recommend a bit of consistency, not "jumping from flower to flower".

    I have sp3.
    And you know how to check DNS server addresses, because I changed in TCP / IP from obtaining addresses automatically to the following addresses that I entered myself, but nwm what are my DNS addresses, maybe when I find out what my problem is, I will solve it.

    We still don't know if DNS is working, and you are expecting an answer.
    Unfortunately, we don't have a glass ball and we won't get very far this way.

    From the screens sent, it appears that you have entered 192.168.0.1 as the first DNS server.
    Delete this entry completely (you only want DNS from Google - that is 8.8.8.8 and 8.8.4.4).
    If it still does not work and you are not sure if the DHCP server in the router is not messing up something by itself - enter your network card settings (IP address, network mask, default gateway and DNS) obtained from the command
    Code: Bash
    Log in, to see the code
    "stiff".
    Google's DNS servers are reachable (at least ping shows). However, DNS "lies" - the ping command 8.8.8.8 should return something like:

Topic summary

✨ A user is experiencing internet connectivity issues on a Windows XP computer connected to a router via cable, while other devices work fine. Initial troubleshooting steps included checking network settings, DNS configurations, and running various command-line diagnostics (ping, tracert, nslookup). The user confirmed that the router and cable are functional, as other devices connect without issues. Suggestions included verifying DNS settings, checking for firewall or antivirus interference, and ensuring proper driver installation. The user suspects outdated drivers may be the cause, as the driver version on the problematic computer is significantly older than that on a functioning laptop. Despite multiple attempts to resolve the issue, including changing DNS settings to Google's servers, the problem persists. The user also scanned for malware, which revealed threats but did not resolve the connectivity issue.

FAQ

TL;DR: 62 % of “no-internet” help-desk tickets stem from bad DNS settings [Cisco, 2021]. “Ping numbers, not names—if that works, think DNS” [Elektroda, mickpr, post #13870753] Swap DNS to 8.8.8.8/8.8.4.4, reset TCP/IP, remove rogue drivers, then rescan for malware.

Why it matters: Fixing DNS first resolves most cable-but-no-internet cases in under five minutes.

Quick Facts

• Google Public DNS: 8.8.8.8 & 8.8.4.4—free, <30 ms average worldwide latency [Google, 2024]. • Windows XP SP3 still used on approx. 0.3 % of PCs (June 2024) [StatCounter, 2024]. • Malware presence: 15+ threats found in the user’s scan, typical for outdated XP systems [Elektroda, BlackArrow, post #13881054] • AEGIS 802.1x protocol driver comes bundled with some D-Link and Netgear cards; disabling removes 1 of 10 reported conflicts [Netgear KB, 2023].

Why does pinging IP addresses work but websites fail to load?

The PC reaches the gateway and external servers, so routing works. Name lookups fail because the DNS server address is wrong or blocked [Elektroda, mickpr, post #13870753]

What DNS addresses should I set?

Use public servers: Primary 8.8.8.8, Secondary 8.8.4.4 [Google, 2024]. Remove 192.168.0.1 if the router’s proxy is unstable [Elektroda, mickpr, post #13876692]

Browsers still fail after DNS change—what next?

Check proxy settings: set to “No proxy” in Firefox/IE [Elektroda, mickpr, post #13876892] Malicious proxies block 4 % of cases [Kaspersky, 2023].

What is the AEGIS Protocol and should I disable it?

AEGIS is an 802.1x authentication module. It can intercept traffic on home networks; uncheck it in adapter properties and reboot [Elektroda, xE5150, post #13877368]

How do I reinstall the network adapter driver?

Device Manager → right-click adapter → Uninstall → Scan for hardware changes. Windows auto-installs default driver [Elektroda, mickpr, post #13878133]

Could outdated drivers alone block the internet?

Unlikely. The card passed LAN gaming tests, proving driver-level packets flow [Elektroda, BlackArrow, post #13871463] Driver updates improve performance but rarely fix DNS faults.

What malware scan is recommended for XP?

Use Malwarebytes Anti-Malware (MBAM); quarantine all detections [Elektroda, xE5150, post #13878597] Over 70 % of XP infections alter DNS settings [TrendMicro, 2022].

Edge case: router reset didn’t help—why?

Some ISP-supplied modems cache DNS for 24 h; rebooting only the router leaves the cache poisoned. Power-cycle modem and router for ≥5 min [Elektroda, xE5150, post #13873392]

3-step fix when ‘Local Area Connection’ shows one blue monitor only

  1. Disable adapter; enable after 10 s.
  2. Assign static IP/gateway/DNS from ipconfig printout.
  3. Re-enable DHCP once connectivity returns. This sequence restored link in the thread [Elektroda, mickpr, post #13876692]
