Hi Daniel, When your firefox is hanging:
Can you ping a host? eg: www.latrobe.edu.au?
ping google.com PING google.com (74.125.237.1) 56(84) bytes of data. 64 bytes from syd01s04-in-f1.1e100.net (74.125.237.1): icmp_req=1 ttl=51 time=15.4 ms 64 bytes from syd01s04-in-f1.1e100.net (74.125.237.1): icmp_req=2 ttl=51 time=13.9 ms 64 bytes from syd01s04-in-f1.1e100.net (74.125.237.1): icmp_req=3 ttl=51 time=14.0 ms Can you ping the gateway? route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 131.172.182.250 0.0.0.0 UG 0 0 0 eth0 131.172.182.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 ping 131.172.182.250 PING 131.172.182.250 (131.172.182.250) 56(84) bytes of data. 64 bytes from 131.172.182.250: icmp_req=1 ttl=255 time=0.362 ms 64 bytes from 131.172.182.250: icmp_req=2 ttl=255 time=0.353 ms 64 bytes from 131.172.182.250: icmp_req=3 ttl=255 time=0.357 ms 64 bytes from 131.172.182.250: icmp_req=4 ttl=255 time=0.360 ms Can you ping your network interface (eth0) ping localhost PING localhost.localdomain (127.0.0.1) 56(84) bytes of data. 64 bytes from localhost.localdomain (127.0.0.1): icmp_req=1 ttl=64 time=0.028 ms 64 bytes from localhost.localdomain (127.0.0.1): icmp_req=2 ttl=64 time=0.021 ms 64 bytes from localhost.localdomain (127.0.0.1): icmp_req=3 ttl=64 time=0.017 ms 64 bytes from localhost.localdomain (127.0.0.1): icmp_req=4 ttl=64 time=0.020 ms 64 bytes from localhost.localdomain (127.0.0.1): icmp_req=5 ttl=64 time=0.028 ms 64 bytes from localhost.localdomain (127.0.0.1): icmp_req=6 ttl=64 time=0.022 ms Can you work out how far out you can go? with ping it appears I can go world wide. It is all very odd. Regards Stripes On 09/01/13 16:02, stripes theotoky wrote:
Hi,
I am running Ubuntu 12.04 on a Dell Optiplex 780. It used to work fine network connectivity no problems with previous versions of Ubuntu but now accessing the web is almost impossible in the last hour I have had to drop and reestablish the connection to the network about 15 times. In fact just about every time I click on a link Firefox just sits there churning away trying to connect and getting nowhere for as long as I care to leave it trying.
I have a wired connection via a University LAN. If I disconnect then reconnect then reload the page it is there almost instantly.
It doesn't appear to be a Firefox problem as I get similar with aptitude from the comment line and Chromium.
It doesn't seem to be a network problem as other computers plugged into the network connect and remain stable.
The only weirdness that seems to be from the network is the proxies sometimes it ONLY works with auto detect sometimes it only works with manual and this can vary several times throughout the day.
My best guess is something screwy in Ubuntu or a network cable going bad. I have a new cable on order to eliminate that any ideas what else it could be?
Stripes.
