Hello XxSpaceBoyxX,

It helps if you turn-off IPv6 communications....

Edit /etc/modprobe.conf and add this lines...

#Turn off IPv6
alias net-pf-10 off
alias ipv6 off

You could try using PIO mode for the network card. Yes it would require you to recompile kernel... PIO mode is usually used when hardware has a bug, however using it for a 8139 Realtek chipset card made it work. Check if its dropping packets, thats what mine did and I got a similar speed.

You could try optimizing Firefox some before that. I'm not sure how effective it is but I just read another thing today saying it's very effective.
Open Firefox and type about:config in the address bar. When the page comes up type pipelining into the field at the top. Three items will show. Change the two falses to trues and change 4 to 30...or 50 or whatever. Some people say to go as high as 100 but the thing I just read said 30. See if that helps any. It may not.

well i couldnt try to recompile the kernel, im pretty new to linux and have no clue where to start=)
i tried mandrake 10.1 out to see if it made a difference and sure enough the connection was equally slow
im about to install slackware to see if that might help =)

question : how do i update the kernel? please =) and thanks for being understanding and not flaming me with "die noob" type responses

We try not to flame people here .

There are a couple of different ways to do kernel upgrades. If your distro (or a third party) supplies a format that your package manager (RPM on Mandrake, dpkg on Debian, etc.) can understand, you can install the new kernel just like any other package and reboot. You may also compile a kernel for yourself from the official sources from (many distros add their own patches to the kernel). This is not as hard as it sounds ... there is a guide on how to do it here on LQ, so try to follow that if you want to play with it.

As for your problem, it's an ointeresting one. Maybe you ccould try launching ethereal and seeing if there's a lot of bogus traffic flying around gumming things up. Also some basic info (system stats, network connection type, etc.) would help in troubleshooting.

basic info =)
celeron 2.0ghz @100mhz
512ddr @333mhz
ati raedon9000
WD 20gb udma 100
linksys LNE100tx net card
linksys befsr11 router
docsis compliant terayon cable modem @ 3mbit X 512kbit

router is acting as dhcp server and from double checking my ifconfig it would appear the net card is properly pulling the ip dns subnet and all of that from the dhcp.

are there any special settings that need to be dealt with on the router such as dynamic routing (what the heck is that anyway?) with RIP1 and RIP2 (what are those? *gasp*) that i need to deal with? (i name this because i have nfc what it does

as far as distros ive run fc3 and mandrake10.1 with similar results of 1kb/sec or lower xfer rates. ive read as many of the fixes as i could stomach, tried them all and then some *minus recompiling the kernel* to no avail =(

halp! i borked it! =(

edit-> what is this??->Bcast:

Self-Loathing BUMP =/

well after talking it over with my woman, her untechnical self told me "well why dont you plug the computer right into the modem?"

so i did /sniff

apparently its a problem with my router, so if anyone wants to help me out on setting up the router please let me know!! my aim is xxspaceboyxx =) or just leave a message on here

im actually pulling more bandwith on FC3 than i did on windozeXP with the same setup (modem into netcard) heh kinda funny =)

thanks in advance!!!
