I made some additional measurements: If I generate downstream traffic with the maximal reachable bandwidth, and I simultaneously ping my router, I see, that the round trip time of ping is increased by a factor greater than a hundred.
Here's a snippet of ping output: 64 bytes from 10.0.0.1: icmp_seq=58 ttl=255 time=206 ms 64 bytes from 10.0.0.1: icmp_seq=59 ttl=255 time=171 ms 64 bytes from 10.0.0.1: icmp_seq=60 ttl=255 time=142 ms 64 bytes from 10.0.0.1: icmp_seq=61 ttl=255 time=156 ms 64 bytes from 10.0.0.1: icmp_seq=62 ttl=255 time=531 ms 64 bytes from 10.0.0.1: icmp_seq=63 ttl=255 time=147 ms 64 bytes from 10.0.0.1: icmp_seq=64 ttl=255 time=264 ms 64 bytes from 10.0.0.1: icmp_seq=65 ttl=255 time=281 ms 64 bytes from 10.0.0.1: icmp_seq=66 ttl=255 time=175 ms 64 bytes from 10.0.0.1: icmp_seq=67 ttl=255 time=493 ms 64 bytes from 10.0.0.1: icmp_seq=68 ttl=255 time=315 ms 64 bytes from 10.0.0.1: icmp_seq=69 ttl=255 time=2.16 ms 64 bytes from 10.0.0.1: icmp_seq=70 ttl=255 time=1.14 ms 64 bytes from 10.0.0.1: icmp_seq=71 ttl=255 time=1.06 ms 64 bytes from 10.0.0.1: icmp_seq=72 ttl=255 time=1.60 ms 64 bytes from 10.0.0.1: icmp_seq=73 ttl=255 time=2.16 ms 64 bytes from 10.0.0.1: icmp_seq=74 ttl=255 time=1.52 ms 64 bytes from 10.0.0.1: icmp_seq=75 ttl=255 time=2.81 ms 64 bytes from 10.0.0.1: icmp_seq=76 ttl=255 time=2.27 ms 64 bytes from 10.0.0.1: icmp_seq=77 ttl=255 time=1.56 ms If I generate upstream traffic (which is not slower than with the former Ubuntu-shipped driver, rt2500), there's only a slight difference in ping times (e.g.: 1- 2 ms => 2- 4 ms). -- Low data rates with Ralink RT2500 PCI WLAN card https://bugs.launchpad.net/bugs/154524 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
