I have had the same problem here. I do not know when it started exactly (it wasn't the when I first installed Ubuntu but suddenly some websites (like google maps) started to display half maps. Then I was able to pinpoint to a problem with wireshark. First I added the line "net.ipv4.tcp_window_scaling = 0" to sysctl. the was better but not gone. Then I also added net.ipv4.tcp_wmem = 4096 16384 131072 and net.ipv4.tcp_rmem = 4096 87380 174760. Now all is forking fine again.
If it helps I can put requested info below, just let me know what I can do. What is of more interest was that Wireshark saw tcp checksum errors. The exact message was "Checksum: 0xaa59 [incorrect, should be 0x2035 (maybe caused by "TCP checksum offload"?)". That is gone now. -- Cannot connect to router/server/proxy with bad TCP Wscale implementation https://bugs.launchpad.net/bugs/89160 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
