Internet connection Help

[compgeek]

First of all, I am a total newbie to Linux and I need some help.



Okay, I'm running Knoppix 4.0 and unable to connect to the internet.(Running on a laptop) I have cable running through a router if that helps. I tryed running the network card config and it couldn't find my wired network card. The wifi card config didn't work either. Is there something I'm missing?

Any suggestions?

Any suggestions?
You've given a small amount of information in telling us that you have a router, but not enough for us to resolve the problem. So here are some questions:

What router, make and model?

What is the wired NIC, make and model, or if built into the motherboard, what is that?

Are you sure that you are not on the Internet (yes, we have had people ask this that were on the Internet all along)?

What error are you getting? Give us the exact error.

Have you tried manually setting the network settings with netcardconfig?

Have you tried to ping the router's IP address? Have you tried to ping an Internet site by IP address? Have you tried to ping an Internet site by URL? And what were the results?

Does your router have a feature that limits access by MAC address? (and if it does and it's enabled, try disabling it.)

What version of Knoppix are you really using? 4.0 was only officially released in German at T.A.G. Are you using 4.0.2, or something else?

What router, make and model?
Linksys Model # WRK54G (Wifi router with 4 port switch)

What is the wired NIC, make and model, or if built into the motherboard, what is that?
Marvell Yukon 88E8036

Are you sure that you are not on the Internet (yes, we have had people ask this that were on the Internet all along)?
Yes.

What error are you getting? Give us the exact error.
I cannot configure either of my network devices.

Have you tried manually setting the network settings with netcardconfig?
No and wouldn't know how on Linux.

Have you tried to ping the router's IP address? Have you tried to ping an Internet site by IP address? Have you tried to ping an Internet site by URL? And what were the results?
No and wouldn't know how on Linux.

Does your router have a feature that limits access by MAC address? (and if it does and it's enabled, try disabling it.)
Disabled already.

What version of Knoppix are you really using? 4.0 was only officially released in German at T.A.G. Are you using 4.0.2, or something else?
4.0.2

Should work.


Marvell Yukon 88E8036
This is likely the source of the problem. It's both a gigabit card and PCI-E. I don't know if there are drivers in Knoppix yet for it or not. Maybe someone else does now that we have the NIC pinned down, but if you have one available I woould try a different NIC, something in the 10/100 class and just basic PCI and see if that doesn't resolve it (the card is wasted when talking to that router anyway, as it talks at 10/100).


What error are you getting? Give us the exact error.

That doesn't really tell us what error you get.


Have you tried manually setting the network settings with netcardconfig?
No and wouldn't know how on Linux.
From either a shell command prompt or the Knoppix menu, run Netcardconfig. Answer the question about DHCP in the affarmative. tell us what happens. If that doesn't work, note your Internet settings under Windows (write them down). Run Knoppix and then run netcardconfig again. Answer the DHCP question NO, and then answer the set of questions asked from your notes.


Have you tried to ping the router's IP address? Have you tried to ping an Internet site by IP address? Have you tried to ping an Internet site by URL? And what were the results?
No and wouldn't know how on Linux.
ping is a shell command in linux just as it is in Windows (except that the default in Windows is 3 pings, in Linux you use a switch to control the number of pings or just stop it when you are satisfied). But all of this seems unimportant in light of the above answers.


Does your router have a feature that limits access by MAC address? (and if it does and it's enabled, try disabling it.)
Disabled already.
Good. It has been a problem for some users.


4.0.2
Good to know. It shouldn't be an issue for this problem but at least this tells us we know we are talking about the same version.

I tryed running "netcardconfig" And it had shown: "No supported network cards found." within a few seconds of me typing in netcardconfig.

That pretty much takes us back to my speculation that the Marvell Yukon 88E8036 is not supported yet in Knoppix. Any chance for trying a different NIC?

Would this card work? It is the wifi card: Linksys WPC54G.

Unfortunately most manufacturers don't release technical documentation on their wireless cards and chipsets and few provide decent drivers for them. So wireless card support in Knoppix is not great, and even more so for 802.11g cards. I don't recall seeing good reports here in the forums on that card and no one has seen fit to add any information to the wireless networking section of the wiki for that card. I have 4 wireless cards (I don't even count the USB crap) and only one of them, a Belkin 802.11b card, works under Knoppix. And that only started working in recent releases; I had it for a couple of years before it was finally recognized by Knoppix. My suggestion would be to get a cheap 10/100 wired nic working first (CompUSA has one for $2.99 ar this week that will work fine with Knoppix).

[compgeek]

Could you specify on that Belkin card's model number?

[Harry Kuhman]

Could you specify on that Belkin card's model number?
I can, but be warned that many card makers change chipsets but keep the same model number (I expect this is so that they can keep selling cards under the same model number and not disrupt their supply system every time they make a model change). Unless you can find an exact match for this card I would still suggest that you start with a wired NIC.

The box is simply marked PCMCIA wireless 802.11b 11Mbps and there is a paper sticker on the bottom flap marked ver. 2101. The card itself (but not the box) shows a model number on the back that reads "model no. F5D6020 ver2" and there is a paper label reading "ver 2101" below this. The card is about 2 years old and I don't know if you can still find one made with the same chipset / version number.

This particular card does work with Knoppix 3.9 and above (maybe 3.8, I don't recall for sure). It does not work with prior versions of Knoppix, some seemed to recognize it but none would properly configure it. And, of course, with a wireless card you need to to extra setps like set the ssid and wep key, you can't just boot the CD/DVD and be on the network.

Did your wireless network card come with your laptop? If so, then you might want to check out <http://www.linuxlaptops.com> and click on Laptops&Notebooks. Someone might have posted some info there that could possibly help you to configure your wireless network card.

A few minutes ago, I posted a reply to "Wireless card not recognized" with similar information. You might want to check it out--specifically the part where I did some research to find out which driver is used in XP. It will be something like *.SYS. You can get that information either via the web or via the Control Pannel in XP. After you know what the name of the driver is, then you'll need to find the correct .INF file (and possibly a few other files). I did that for my own setup via the 2 find statements. Don't be alarmed if everything doesn't work for you the first time around--it didn't work for me the first time either. Actually, it took me a series of trials and errors to hack together my setup. (I could have done it much quicker had I downloaded the driver from the ndiswrapper website, but that would have failed with my setup--it's a long story.) :) A laconic version of that story is that I was running Knoppix via a livecd, and I insisted upon working with the XP drivers (just because I heard it was possible).

Anyway, this should be enough to at least help you get started. By the way, if knoppix also has an issue with your wired netword card, then you can do something similar to get it working.
