I've had similar problems, as far as I can tell it's due to the following rule in the router's firewall config
TCPMSS tcp -- anywhere anywhere tcp flags:SYN,RST/SYN TCPMSS set 1360 I've had problems with this rule before, using a WiFi card with a small MTU. It was actually increasing the MSS and making it too big for the MTU. I'm sure the intention of the rule is to decrease the MSS only. Removing the rule with iptables -D fixes the LinkedIn problem. So far it doesn't seem to have broken anything else. Note that the rule will come back if the router is rebooted. -- linkedin very slow on Firefox Linux only https://bugs.launchpad.net/bugs/314713 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
