Hello, >From time to time, my network shows some poor performance. My 64 bit Arch Linux box is connected with a wireless connections with a RaLink RT2561/RT61 802.11g PCI, the system is up-to-date. The symptoms are: * Looking up a website takes very long, or it will never load at all. Only in Chromium snapshot, Firefox loads the same page instantly at the same time. However, some videos on Youtube load for 25% and refuse to continue to fetch more (in both browsers). * Kopete is unable to keep a connection with either MSN or my Jabber accounts. They simply time out. * SSH connections drop dead (or are interrupted for minutes). No high traffic involved at all. The problem does not always occur, at some days I have a good connection, but sometimes the symptoms above occur. I suspected it had something to do with IPv6, but disabling it did not have any effect. I don't think it's interference either, the connection to the router is quite healthy: normal response time, 0% packet loss (also with servers outside my network), download rates are often at their max. I also have a laptop with 32 bit Arch Linux installed, using the Atheros wireless drivers. It also runs Chromium and doesn't show any problems whatsoever, on the same network. When I run tcpdump on both machines, I see many lines like 12:09:37.134509 00:30:3f:50:19:e5 (oui Unknown) > 00:18:f8:45:10:c3 (oui Unknown), ethertype Unknown (0x05ec), length 1530 where 00:30:3f:50:19:e5 is the wireless router (unsure about the other MAC, I'm on a shared network). My laptop shows seems to capture much more of these messages than my PC does, not sure whether that's a good thing or a bad thing. Could it be a driver issue? I'm tending to think that is the case, actually. Any other hints are very appreciated. Kind regards, -- Bram Schoenmakers What is mind? No matter. What is matter? Never mind. (Punch, 1855)
