Pfsense causes internet to freeze.

Your link on dc0 is going up and down all the time. Check cable, switchport and NIC.

oakis

Everything seems to be fine.

hoba

How long is the cable between switch and nic? I have seen funy things happening when using too short cables on some equipement. Your logs clearly state that the link is coming up and down all the time.

oakis

I think its a 3-m cable.. tho it has been working for 6 months without this problem before.

hoba

Things always tend to run fine until they break ;)
Still looks like a hardwareproblem to me. Maybe reset the switch.

oakis

Tried to restart the router(pfsense), the switch and the modem.

hoba

This is a hardwarefailure. You have to start changing equipement to find out what's wrong I guess.

oakis

Seems like it only happends when there is trafic.

The time that i was sleeping it didnt fail.

Dunno if this helps.

 LAN interface (dc0)
Status 	up
IP address 	192.168.0.1  
Subnet mask 	255.255.255.0

Do i get all those collisions because i use a hub, and not a switch?

I think you have some autonegotiation issues. You could try to hardcode the interface speed by using hidden config.xml magic. See http://doc.m0n0.ch/handbook-single/#FAQ.hiddenopts for how to set mediaoptions. It's the same for pfSense.

Trying it now, still have alot of collitions though!

oakis

Still not working. The wierd thing is that it doesnt happen between 00 and 09 in the night/morning. :S

You'll always get that with a hub, that's why it's been pretty much impossible to buy one for the last 5+ years ;)

oakis

Well, our switch broke down and i had this old baby still. :D
(the problem did not start when i switched to hub)

Cry Havok

If you've always had high collisions then you had a very badly broken switch. Your other problems (as you've been told, repeatedly) strongly point to broken hardware.

oakis

No i have not always had high collisions, only when using the hub.
