linux-backports-modules-2.6.27 does not seem to be the right package: as the second comment says, this problem appears in Ubuntu 8.10 (intrepid) without backports.
I have the same experience: an Intel wifi "link 5300" card in my laptop, which connects usually at 54 Mb/s or sometimes 60 Mb/s to my wireless N router under Ubuntu 8.10. When using Windows Vista on the same machine, the connection speed is 130 Mb/s. (Of course, the actual transfer rates do not reflect these figures. The figure for Ubuntu is what is reported by ifwconfig. Signal strength is 100%, so that is not a problem.) -- iwlagn (4965) poor wireless-N performance on Intrepid Beta https://bugs.launchpad.net/bugs/282453 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
