I have recently installed redhat 7.2 on my home computer and am having trouble downloading from internet. We have a surfboard cable modem with a linksys cable router with 3 computers connected. I also have windows98 and copied down info i could find like ip address, subnet mask dns servers, etc...I tried using this info in lots of different ways in the network config. screen, but with poor results. The connection is blazing fast on the windows system, but on the linux system, when it does attempt to display pages, it is very slow.
Sorry, but I am novice, and don't really know if i have static ip, dhcp, dns, or what these things really mean....
when i installed redhat i chose dhcp on the network configuration screen, how would i now change this?
it is netgear fa311 ethernet card.i'd like to ditch microsoft, but linux is of little use to me if i cant transfer files!
thanks for any and all help!
NEW PROBLEM
Now i booted linux and used the network config. utility to try and turn off dhcp and it tells me the ethernet card can not be initialized....thanks again for any help

no no no wrong don't turn off dhcp it stand for dynamicHostConfigurationProtocol you need it to init your ethernet because your network card thinks it's on the LAN and you don't have info from your cable company to do it yourself

Unfortunately, with a home LAN operating behind a router connected to a cable modem, you really *should* learn at least a little about DHCP, staic addressing, DNS, etc. But anyway:
Actually, whether or not you need to use DHCP on your Linux box depends on how you have the Linksys router set up. If it is supplying your IPs via DHCP, then all of your machines need to be using DHCP to get their addresses. If not, you will have to assign each machine its own individual IP manually. If you entered all of your networking information (IP, subnet mask, DNS server IPs, etc.) by hand on your Windows computers, then your internal network is *not* using DHCP, and you will have to enter that same information in the Linux box (except that you must choose a unique IP). If your Windows boxes get their IPs automatically from the router, then your internal machines *are* using DHCP, and the Linux box will have to use it as well.
I'm sorry I can't go through the whole process right now, but a) it's 3:30 AM, b) I haven't used Redhat's Network Configuration Utility, and c) A step-by-step walkthrough
would make for a *very* long post.There are a lot of good resources on the Web which address your issue, I'd suggest doing a search at www.google.com, using combinations of keywords such as "cable modem" "DHCP" "linux" "NAT" and "LAN".

the boxes think they are on the LAN...that's obvious because they are, but the swich also thinks it's on the LAN...BECAUSE THAT'S HOW CABLE NETWORK WORKS and the cable company configures the modems through DHCP and I personally don't have enough info to set it up myself manually(I too have cable;And yes I would be able to set it up but cable company perfers to do it by DHCP because of security....but hey man, maybe your company can provide you w/ this info in the name of troubleshootin'

Check netgears site for updated lInux drivers for the FA-311... I owned an FA-312 that I was unable to get working under Redhat, sorry for the lack of encouragement but Netgear Cards and lInux dont mesh well... :-(...

Trader,
Re-read the post carefully before you go off yelling at us in capital letters. The Linksys is a *gateway router*, not a switch. The cable company may use DHCP, and the Linksys can deal with that on its external (modem-side) port, but on the LAN side it can operate as either a DHCP server, or as just another staically-addressed device on the LAN. On the LAN side, what the cable ISP does/uses is of no consequence. Trust me- my LAN operates on static IPs, even though my cable ISP interfaces with me using DHCP; it's a fairly common setup.
As for the Netgear card itself; no, the 311 and 312 haven't had a good track record under Linux. It wasn't until very recently that support for the driver (natsemi.o) was built into the kernel. If need be, the module's source code and compilation instructions can be found at http://www.scyld.com/network/ethercard.html, although I would guess that Rh 7.2 is new enough to have the driver.

I've set several cable and dsl systems
up with the Linksys router(ppoe and not). I just set
a surfboard modem up (the kind with the
USB or UTP hookup). I use a Linksys
at the house for a 'hardware' firewall
servicing several computers from Solaris
to Windows,98,XP,2k and Linux of course.To get around the Netgear (junk) buy a $20
SMC card or high dollar 3com card and that
should fix any 'card' issues.For the install: How did you set up your
first computer with windows on it? If you
just plugged the modem into the router
and it worked then you have DHCP enabled
and you need to tell Linux to boot using
DHCP (netconf,linuxconf) Otherwise if
you manually set the IP you will need to
give it a 192.168.1.XXX from the router as
the IP use the 192.168.1.1 (or whatever
if you changed default) as the gateway, Then
look at you cable modem and see what the
dns #s are and put it in. Domain name doensn't matter to linux.If you just plugged it in and everything
worked then it should for linux just as
easy. You might just have a flaky driver
for you Netgear card.Good Luck...

I too have had this same problem. I have a Linksys router/firewall running as a DHCP server for my home LAN and as the DHCP client to the cable company. I have a 3com 10/100 network card. RedHat 7.2 is very slow going out to the internet. Internal to the LAN, It is very fast. I am running Mandrake 6.1 set up the same way, or as close as I could get it. Mandrake 6.1 and Windows 2000 run fine. In addition in notice I loose about 85% of my packets when I ping an external address, but loose none when I ping an internal address. I have checked my wiring and the 100 light is on, on the router. The only difference is that my other cards are 3com 10's that do not run in full duplex. I noticed that the full duplex light is lit on the router for my 100. Any suggestions would be greatly appreciated.

I run about the same set up. 2 windows,
2 mac/osx and an older digital server
running rh7.2, my problem is that i have a
linksys eth card and i think the driver is
set up, yet i can't connect to the
network(the router doesn't show it in the
dhcp clients table) and the digital says
that the network is unreachable??i have togo, but i can give more info later.
any suggestions??

folks, I have a similar (if not the same) problem. I set up dhcp. All of the lights on the linksys router are light. I put the dns configuration in the primary and secondary fields of the redhat network configuration tabs and the 192.168.1.1 in the domain field (I'm not sure if that is correct). However...I cannot even ping the linksys modem. Any suggestions. I am going to try changing the cable...but I doubt that's it. (By the way...I finally got the linksys router to work with comcast...ONLY AFTER Comcast reset the modem)
Thanks
