Network/Download problems


Hey all, I'm pretty new to linux, and have been having a weird problem with it.

Right now, I've got Mandrake 10 installed on an Acer TravelMate 8000 with a Broadcom NetXtreme Gigabit Ethernet adapter built-in.

My problem is that when I attemp to download files from the web, something goes wrong 100% of the time - the files corrupt or something. If I try to download an archive, it either won't open or will only contain a fraction of the files it should. When I have checked the MD5 against values from the servers, they never match. I can surf the web fine, and get on AIM fine, but downloading doesn't work.

I have Windows installed on another partition, and I have no problems when using it.

I've tried reinstalling the OS, and even tried a couple different distros, but they all do this.

I've run out of ideas, and no one I've talked to has any idea what to do, so hopefully someone here can help me out.

Thanks so much,
-Ben Foster

You may want to start by turning OFF IPV6 in /etc/modules.conf

e.g.

alias ipv6 off

Thanks opjose for the quick reply.

Unfortunately, I added that alias to the file, rebooted, and am still having the same problem.

Any ideas?

Thanks

If an 'lsmod | grep ipv6' (as root) shows it's still loaded try adding it (and "alias net-pf-10 off") to /etc/modprobe.conf.
I think modules.conf is deprecated in linux 2.6.

Something tells me you may have a problem with the driver for the Gigabit adapter. If you look in the system logs do you see messages about the device resetting or interupt problems?

The only stuff I found from dmesg that looked related was this:

Code:
Broadcom Gigabit Ethernet Driver bcm5700 with Broadcom NIC Extension (NICE) ver. 7.0.0 (08/14/03)
eth0: Broadcom BCM5705 1000Base-T found at mem d0200000, IRQ 6, node addr 00c09f43a3ef
eth0: Broadcom BCM5705 Integrated Copper transceiver found
eth0: Scatter-gather ON, 64-bit DMA ON, Tx Checksum ON, Rx Checksum ON, 802.1Q VLAN ON, NAPI ON
ip_tables: (C) 2000-2002 Netfilter core team
ip_conntrack version 2.1 (7168 buckets, 57344 max) - 300 bytes per conntrack
NET: Registered protocol family 17
eth0: driver changed get_stats after register
bcm5700: eth0 NIC Link is UP, 100 Mbps full duplex
Is there something else I should be looking for, or another log I should check?

Hmmm, do you download by clicking a link in a browser or du you use some ftp client?
If the latter, make sure you download in binary form and not ascii.
In gFTP that's in the FTP menu for instance.

I'm running several servers with the same 100mbps interface, so I doubt that this is a driver problem, or a hardware problem with your integrated interface.

The problem could be external to your machine... In which case you'll need to physically check everything out...

From the Linux side, one common cause for download failures, are MTU size mismatches.

If the MTU size is not correct for your Internet connection, the end result is usually that transfers will drop over time, they will never finish, or the xfer seems to stop just prior to the 100% mark.

Not 100% sure what you mean here, but I checked the MTU size on XP and then checked it on Linux, and they're both set to 1500...
