Public bug reported: Binary package hint: linux-source-2.6.20
After recent change of my router to Linksys WRT54GS I encountered problem described here (http://ubuntuforums.org/showthread.php?t=383390). Symptoms are as follows: some web pages load without problem, but some are not available. If I ping those servers everything is ok, but traceroute is not able to trace the path to reach them. For example 1: athlon1.local (192.168.1.104) 0.276ms pmtu 1500 1: 192.168.1.1 (192.168.1.1) 1.145ms 2: cisco1.mechcom.net (216.207.12.1) 221.901ms 3: chi-edge-18.inet.qwest.net (65.121.248.73) asymm 4 249.917ms 4: chi-core-01.inet.qwest.net (205.171.20.1) asymm 5 120.944ms 5: ewr-core-02.inet.qwest.net (67.14.7.14) asymm 6 80.530ms 6: ewr-brdr-02.inet.qwest.net (205.171.17.130) 233.134ms 7: 205.171.1.98 (205.171.1.98 ) asymm 8 108.639ms 8: ae-1-55.bbr1.NewYork1.Level3.net (4.68.97.129) asymm 9 260.597ms 9: as-0-0.bbr2.London2.Level3.net (4.68.128.110) asymm 12 306.417ms 10: ae-15-55.car1.London2.Level3.net (4.68.117.143) asymm 11 341.062ms 11: tge9-3-146.core-r-1.lon2.mnet.net.uk (212.187.196.82) asymm 12 158.807ms 12: 85.133.32.134 (85.133.32.134) 372.070ms 13: 82.211.81.76 (82.211.81.76) 265.080ms 14: no reply 15: no reply 16: no reply 17: no reply . . . through the max number of hops, until timeout. sollution to this was to add to /etc/sysctl.conf the following two lines net.ipv4.tcp_wmem = 4096 16384 131072 net.ipv4.tcp_rmem = 4096 87380 174760 Now everything works fine. There should be a solution implemented ASAP to make everything work straight of of the box. As far as it is not solved with Linksys firmware update .
