Im running FC5 on a fresh install, nothing else really done or changed, because i cant get on the internet. It used to be horribly slow, taking 30 seconds to load google on a 3.5mbit broadband connection. Now I cant even ping my router.
I have disabled SE Linux and the firewall, and then reenabled the firewall, trying to ping my router after applying the changes each time and restarting. Ive managed to unreliably ping my router a few times, with around 35 bad attempts until i get 0.8 ms around 10 times.
It then says its unreachable.
[root@fedora ~]# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
Advertised auto-negotiation: Yes
Supports Wake-on: pumbg
Current message level: 0x00000001 (1)
Link detected: yes
The ping is still running, and with around 50 bad attempts then 4 getting through, then 15 more not getting through, then 1 getting through. You get the drift.
What do i do?
What kind of ethernet card do you have? Find out with
Maybe it needs some extra modules installed.
I cant remember motherboard model,i'll look it up. (onboard ethernet)
But since its a fresh install, ive reformatted and its reinstalling now(this would have to be the 6th time with fedora). Will post results.
edit: Is it a good idea to disable SE Linux? it says the entire file system has to be relabled if i do so.
If it is a home machine, you can safely disable SELinux.
Went into terminal straight away, and cannot ping the router.
IP is staticly assigned, as before.
ethtool still returns the same.
lspci tells me i have a VIA Technologies Ethernet Controller VT6102 [Rhine-II] (rev 74)
- if router is set to static IP or dhcp
- if computer matches router setting (static/dhcp)
- if DNS servers are set up correclty in /etc/resolv.conf
- if eth0 is up and running or times out
your ethernet card is fully supported, that is for sure.
eth0 is active.
all computers use static IP, though I may try dhcp to see if that works
dns server is set to router just like every other computer.
Change the DNS entries on your computer from the routers IP to the ones from your ISP and try to ping e.g. www.google.com.
Call me blind, but my isp doesnt seem to say the dns settings.So i tried OpenDNS and that didnt work. The LED on the router flashes a bit, indicating some activity. It does this regularly when i try and ping it, and stops when i stop the ping.
edit: Also changed the IP to be 192.168.1.5 rather than 4. Still no luck.
edit: I booted up DSL on the same machine. Works perfect with DHCP and static assignment.
edit: Wow, i start up fedora again, and now its working perfect. No idea how starting DSL fixed it.
edit: Speed problem now. google.com takes a bit too long to load. Yum doesnt work because downloading primary times out, after downloading some of it. This happened on 14 mirrors. Once again, SE Linux disabled, and Firewall enabled.
Please post the contents of your /etc/resolv.conf. Did it really look like this?
If yes, then I ask myself if you changed anything at your router settings (MTU/MRU settings perhaps?). If you did anything to your router, reset the router to factory defaults. Also: Use dhcp, if possible.
