Everybody, thanks for your effort already!!
First I typed ifconfig net0. I got: net0: flags+863<up, BROADCAST, NTRAILERS, RUNNING, SIMPLEX> mtu 1500 inet 192.168.0.188 netmask 0Xffffff00 broadcast 192.168.0255
What does that mean?
Indeed as P.Bes, Icaros Desktop AROS distribution mantainer is saying, I need to learn to basics of networking. So now I am really trying to understand it all.
I found my router's IP number:Router IP address is: 192.168.1.1
Netmask: 255.255.255.0
Router product name: (Huawei) HG655d
connectiontype = IP routed (IP)
My providers DNS are:
Primary DNS server: 194.134.5.55
Secondairy DNS server: 194.134.5.5
I think the computer which I am using now (Linux) has IP number: 192.168.1.0
INFO IP routing table-
0.0.0.0 / 192.168.1.1 0.0.0.0 UG eth0
169.254.0.0 / 0.0.0.0 255.255.0.0 U eth0
192.168.1.0 / 0.0.0.0 255.255.255.0 U eth0
So my Aros computer has to get a number like 192.168.1.2, right? I typed my router's IP as primary DNS in the Network preferences, but got "error in NetDB file static-routes at line 1, col30 syntax error" Then: " Failed to restart network stack" I also used my provider's primary and secondairy DNS, still no connection. I always get: unable to open ...... Error 6" could't resolve host name.
I should leave the network's cars address number in INTERFACE untouched, right?
I always boot-up after I changed something.

Akabane, you should really learn the basics of networking. After all, it's assigning a IP address to a PC and a router is not so different from giving two telephones different numbers, whereas the netmask and the first three digits of IP addresses are your personal phone company.

If the router has an address like 192.168.1.1, then 192.168.1.0 is your network (notice the .0 in the end: it means "the whole network name").

So, you have to give your computer a different number on the same network. 192.168.1.2 can work, because it's different from 192.168.1.1. When two devices have different IPs on the same range, they can communicate each other.

Then, there is the netmask. Let IP addresses being 192.168.1.1 and 192.168.1.2: since the only digit which changes is the last one, your netmask will be 255.255.255.0, which means "the first three octets must be the same, the fourth octect should change". You can however learn more about netmasks on wikipedia.

In the end, there is the gateway. It's the network device which allows connecting to a different network, in this case Internet. Your gateway is, obviously, your router. So the dafault gateway for your network will be, in our example, 192.168.1.1.

Then, once the connection to the internet has been made, you need at least one DNS server to convert "whatever.node.name" to their respective IP addresses. You really should put your providers' ones here, but if you're connecting to the Internet using a good modem-router, it's likely your router has also the ability to work as DNS replicator. So you can try putting your router's IP (192.168.1.1 of our example) as primary DNS, and a known one as the secondary, like OpenDNS and Goolge's ones (try 8.8.8.8, google's public DNS).

Once you have set everything up, do not forget to reboot AROS before trying browsing the net.

If you entered the device just does not have to do anything, leave everything in including the Automatic IP setting on the device, you just put the checkmarks on the Start tab. I've now done a test with my AcerOne Z5, I usually use in WiFi mode. I did a test with the network hub set the RTL8169 device is everything went well, it has worked on the first shot, I attach my screenshot.

-----------------------------------------------------------

Se hai inserito il device giusto non devi fare nulla, lascia tutto in Automatico compreso il settaggio IP sul Device, devi solo mettere le spunte su tab di Start. Ho fatto ora una prova con il mio AcerOne Z5, che solitamente uso in modalit? WiFi. Ho fatto una prova con la Rete Lan settato il device RTL8169 ? tutto ? andato bene, il collegamento ha funzionato a primo colpo, allego il mio screenshot.

I have used the same network chip and had no problems connecting. You could try directly connecting to google via it's IP address and see if the problem is with DNS. Here's one of Google's IP (at least it is today)http://74.125.224.72/

Try the command "Ifconfig net0" in a shell window (no quotemarks). also check your router that it allows connections and dont have any blocking set for new IP?s

Most providers use dynamic ip?s I belive.

also remember to restart for every change you do.
For the DNS you can always use the open DNS servers as input.(this is for a manual setup)

208.67.222.222
208.67.220.220

Usually the DNS servers is your providers servers Your internet provider should have given you information about that. But myself I prefer open DNS that works fine 99.99 of the time here.

Gateway is your routers adress (something like 192.168.1.1) You find it in your routers manual.

Since many routers is delivered with security settings on (like wep/wpa password and blocking new networks etc. many get stuck becauce of their routers security settings.

One way is to turn of the security settings temporarely (no password, allow new netconnections etc) and make the connection work from there. when it works put back the security settings you prefer.

have fun.

!! hint for someone with developer/programming skills.
Would it be possible for AROS and network prefs to read the PCI device info to identify the card used ? and use that info in the network prefs as a suggestion of driver ?

Thank you very much!
You are all very kind and willing to help.
I installed the rtl8169 driver and saved it. Then rebooted the system. Now I still can't get on the internet, but the router light is blinking and the error message that it can't connect takes longer to appear. So there is some progress.
By the way, in Network; do I need to change the primary DNS and the secondary DNS, or just keep the standard settings?
If I type in Shell: ping 127.0.0.1 I'll get: icmp_seq=01 ttl+255 time=0ms, icmp_seq=02 ttl+255 time=0ms, icmp_seq=03 ttl+255 time=0ms, etc, but nothing seems to happen. My router number is my IP number, right? If I type: ping + my IP number, I get a message: ping "ip number": 56 data bytes.
What does that mean?
If my router settings are not correct, what should I change?
For example: static routing, dynamic routing?
With best regards
Akabane

Thank you akabanekuroido,

and here is the driver you should try (rtl8169.device)

Select the device as i told earlier, save your setting and reboot your machine. Sometimes it can take a little while (30 seconds/1 minute) for connection to build.

In order to test the connection open up a shell and type ping x.x.x.x where x.x.x.x is internet addres of your router. You can also try 127.0.0.1 to see if the network is available.

When you still have problems to reach the internet, then that would most likely be be because of router settings. You could try (if you have multiple machines behind the router) to ping the arosbox from another machine.

regards,

If I misread the colors HERE RTL8111/8168B say that is compatible with the AROS.

----------------------------------------------------------

Se ho interpretato bene i colori, QUI dicono che la RTL8111/8168B ? compatibile con i sistemi AROS.
