Internet connection drops out

Every now and again my internet drops out for no apparent reason. I try dhcpcd -k eth0/dhcpcd eth0 and nothing. I try modprobe -r <driver> modprobe <driver> dhcpcd blah blah and nothing. /etc/rc.d/rc.inet1/2/d restart. Nothing. The only thing that works is rebooting my system. Any idea how to reset my connection without rebooting?

Do you see anything in the logs?

What kind of network connection is it? Wireless? Wired?
What chipset does it use?
Is it integrated on the mobo, or a separate device?
What version of SW are you using? 12? 13? 64bit?

Info is needed

Longshot...if you are using Firefox...just go into about:config and disable ipv6.

Err ... a question ... what's the difference between modprobe "drivername" and modprobe -r ?

Mean, what command is better?

"modprobe foo" loads a module called foo.

"modprobe -r foo" unloads a module called foo.

@OP I faced a similar problem the other day and it came down to the driver for the (very recent) wireless chipset being buggy. I upgraded from 13.1 to current and the kernel module that came with the kernel seems to be much better. Of course other things may break going to current and personally I wouldn't do this on a production machine or one that you rely on day-to-day.

OK, I tried disabling ipv6 in firefox. Well, I couldn't ping anything, so I'm not sure that's the problem. syslog is just way too long for it to be useful, and I'm sure the error is so buried to make it impossible to find now. I will check it immediately the next time this occurs.

I'm going to upgrade my system to 13.1 and the latest kernel. Hopefully that will fix the problem. If not, I'll be back.

It's tricky because it does not happen often. I just thought I might have missed a step somewhere in attempting to restart my internet connection. dhcpcd, modprobe and inet1,2,d are the only things I know of. A while ago I had a problem and searching the internet I found a file in /etc/udev/rules.d that I edited to have the correct mac address and that fixed the issue. I just thought maybe someone knew a "secret" like that.
