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

Question

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%...

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

You put DNS addresses in the right place, the internet is working now?

BlackArrow · Answer

Still not working. Maybe there are no drivers for the net? The card is definitely working, because I play with my brother via LAN and everything is fine.

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? Paste Screen, not a picture, router settings.

Now enter in cmd: ping www.wp.pl does that return you results?

BlackArrow · Answer

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. Added after 3 [minutes]: To the question about the results in cmd.

Gateway address responding to ping?

hermes-80 · Answer

Probably some AV or FW blocking access.

bogiebog · Answer

Boot into Safe Mode + Networking. ping 8.8.8.8 ping onet.pl tracert -d 8.8.8.8 ipconfig

mickpr · Answer

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: BashLog 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.

A colleague's modem reset? Maybe my colleague will disconnect the modem and router for 5 minutes from the power supply?

bruno7 · Answer

Let a colleague try it: Reset the TCP / IP stack greetings ps: I forgot to add an attachment from the microsoft website

BlackArrow · Answer

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. Screen of the pc driver version.

bruno7 · Answer

Do you have sp3 installed for this windows xp by any chance? If not, install it.

mickpr · Answer

You're right - you think ... You wrote yourself ... 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.

BlackArrow · Answer

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.

mickpr · Answer

This is what I asked in post # 15

BlackArrow · Answer

I restarted the router and typed the commands you gave, but still nothing.

mickpr · Answer

But we still don't know what their effect is. What did the nslookup www.wp.pl command return? What did the nslookup 212.77.100.101 command return? Error or some normal message? What did ping 8.8.8.8 return, requested by colleague bogiebog in post # 14? What did the ping command 8.8.8.8 return? 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. Help us (that is yourself) and answer these questions.

BlackArrow · Answer

Sorry, but I'm a little lost in all of this. Here are screenshots of the commands' operation: Added after 1 [minutes]: This photo on the right was taken first.

mickpr · Answer

Nobody is a world champion :) 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: BashLog 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:

BlackArrow · Answer

I entered the addresses myself, but go on Thread.

mickpr · Answer

Does any other device (another computer, WiFi, cell phone or tp) connect to the Internet through this router? Show the command result now: Code: BashLog in, to see the code Does the ping command 8.8.8.8 return the same as I showed (in post # 27) in the screenshot?

BlackArrow · Answer

The laptop and my phone are connected to the Internet via this router via wifi on which I am writing and I started the topic. And this is the result of the command:

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