can not conect to linksys router

i have a Linksys wirelsee accesspoint router with 4 port switch all conectons talked about are wired in the switch. the model number of the router is befw11s4

i am trying to my router with both a dell and an emachines computer both do not conect while using knoppix the dell is a dimension 8200 using a cnet pro 200wl fast ethernet adapter and the emachines uses an nvidian force networking controller

i get no internet so i have no clue what to do while in linux any help would be great.

I am vary new to linux just got it this week.

We need the output of ifconfig. Also, try running netcardconfig and say yes to the dhcp question and tell us what happens. Do this for each computer. And I'm assuming that you don't have dhcp disabled in the router or have any strange security feature like MAC address filtering turned on.

here is the output from ifconfig

Code:

knoppix@1[knoppix]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:16:17:79:D4:8F inet addr:192.168.1.101 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::216:17ff:fe79:d48f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1890 (1.8 KiB) TX bytes:1920 (1.8 KiB) Interrupt:5 Base address:0xa000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:14 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:700 (700.0 b) TX bytes:700 (700.0 b) knoppix@1[knoppix]$

and the dhcp failed

Why do you say it failed? It looks like you have a good dhcp setup to me. Or did you manually make these settings?

What does "I get no Internet" mean?

What error messages do you get (exact words)?

I'm wondering if you have an ip6/ip4 type problem as has recently been discussed in another thread. But there is still too little information to diagnose what is happening. Can you ping the router? Can you ping 72.36.188.40 ? Can you ping knoppix.net?

ok to clear things up a bit i was trying to state that i only have internet while in windows not i linux.
now here is a ifconfig before i run the network card config

Code:

knoppix@1[knoppix]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:16:17:79:D4:8F inet addr:192.168.1.101 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::216:17ff:fe79:d48f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7 errors:0 dropped:0 overruns:0 frame:0 TX packets:9 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2201 (2.1 KiB) TX bytes:1990 (1.9 KiB) Interrupt:5 Base address:0xa000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:14 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:700 (700.0 b) TX bytes:700 (700.0 b) knoppix@1[knoppix]$

once i try to do the netcard config i get this message

Code:

Sending DHCP broadcast from device eth0 operation failed. failed. Hit return to exit.

after the netcard config i try ifconfig again and get this

Code:

knoppix@1[knoppix]$ ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:16 errors:0 dropped:0 overruns:0 frame:0 TX packets:16 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:800 (800.0 b) TX bytes:800 (800.0 b) knoppix@1[knoppix]$

I'm at a huge loss to understand what is going on here. Normally what one sees when booting Knoppix on a computer attached to a router is that during the boot process Knoppix does a DCP discovery with the router and gets assigned a local IP address in the same IP range as the router, and has the broadcast address, Domain Name Sever and network mask set. From there they can access the Internet as soon as the boot process finsihes, no setup at all needed.

The thing is, you show that your system (at least one of them) is assigned 192.168.1.101, the broadcast address and the network mask are right. This isn't something that Knoppix ever does on it's own, this information must be coming from the router by DHCP. I'm not at all clear on why you couldn't access the Internet at that point, although we had seem some setup issues that deal with DNS servers that apparently don't treat IP6 properly. But then you do another DHCP setup by running netcardconfig and somehow the system no longer can recognize it's ethernet connection. That's a huge mystery to me and I can't make any sense of it.

Nor can I understand the ping to the router at 192.168.0.1 failing. I had expected the ping to knoppix.net to fail and the ping to the IP address here to work, but I didn't expect there would be any problem pinging the router, I just put that in because it's a logical first step in testing. Once that ping failed the others were sure to, but why it failed is strange.

I'm guessing that you tried the pings after trying the manual netcardconfig. And at that point, for some strange reason, the system no longer thinks it has an ethernet interface. The first test I would suggest is, if I'm correct above, trying the ping to the router right after rebooting, before trying a netcardconfig. You can do an ifconfig first, and that should confirm that the eth0 interface is still functional and that the computer has been assigned an IP address from the Linksys, but don't force a DHCP setup before doing the ping.

I also would suggest making sure that you try all of this from both systems and reporting the result from each.

As I said before, I would also check all of the settings of the router to be sure that there were no "security" features enabled that might muck you up, such as MAC filtering or IP address filtering.

We have on more than one occasion seen a router get into a strange state and do very unexpected things. I can't quite explain the eth0 vanishing from your ifconfig if that's what is happening, but it would be wise to try this:
- Power down all computers, leave the CD in the disk drive.
  Cycle power on the Linksys, give it a minute to fully restart.
  Boot a computer directly into Knoppix without lettiing Windows boot first.
  Try the ping test again.
And just to be sure, we are talking about Knoppix running from CD or DVD, right? You're not one of those who thinks it can be installed and then fails to mention that, are you?

no i am runing all test from the cd i have done a poor mans install on the dell but all test so far have been from the emachines
i also tested to see if i can get a conection directly form the cable modem i was able to access web pages for about a min then i could get no pages to come up if that helps any i will try you others tests and post what i get.
edit
also i had to restart to do the ping test becase i forgot so that is from start up.
