I take back the statement about the roaming causing packet loss - even with the Zydas card NetworkManager reports a roam to "none" for about 6 seconds, but it doesn't seem to actually cause any problems.
However, the throughput of ath5k is very poor. I'm running ping whilst transferring a single 435MB file with scp to test both bandwidth and latency. With Zydas card and zd1211rw driver: ping from 1ms to 35ms. Bandwidth 2.1MB/s. With Atheros card and ath5k driver: ping from 1ms to 3500ms. Bandwidth 573KB/s. Atheros card is internal on a Thinkpad T42p laptop, Zydas card is USB. Even accounting for hardware differences, the performance variance is extreme - changing wifi chipset/driver should not cause 4x bandwidth difference when everything else is identical. The brand of Zydas card I'm testing with is "Safe Home" - www.safehome.com.tw - appears to be a Taiwanese manufacturer that ships direct on ebay, shipping to Europe took around 3 days. Manufacturer supports Linux and the card is cheap and working good so far. http://stores.ebay.co.uk/SAFE-HOME-Online-Shop - I have the one with internal antenna. This testing was done with the Jaunty kernel. -- Some drivers take too long to associate (Was: network-manager 0.7 always asks for WPA passphrase) https://bugs.launchpad.net/bugs/292054 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
