[Bug 1093690] Re: wlan connection via Intel Centrino 6235 chipset very bad
antti tyrvainen, could you please confirm this issue exists with the
latest development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command in the development release
from a Terminal (Applications->Accessories->Terminal), as it will
automatically gather and attach updated debug information to this
report:
apport-collect -p linux <replace-with-bug-number>
** Tags removed: needs-full-computer-model
** Description changed:
- WLAN connection via Intel Centrino Advanced N 6235 chipset is very slow when connected to quite old WLAN modem. WLAN packet loss is about 90% reported by ping. It works, when N-mode is disabled from the client. Bug is available in kernel 3.2.0
