I "upgraded" my HTPC with the top of the line centrino module...
Intel Corporation Centrino Advanced-N 6300
I was using 11.04 and seemed to work fine. Then I had the bad idea to
update to the latest ubuntu LTS 12.04.
only to find out that wifi works really poorly, much worst than the
cheap mini-pci module I was using before.
After sending 450 pings, this is what I get:
Tx excessive retries:2970 Invalid misc:10 Missed beacon:0
on a somewhat decent connection:
Mode:Managed Frequency:5.18 GHz Access Point: xxxxxxx
Bit Rate=243 Mb/s Tx-Power=15 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=50/70 Signal level=-60 dBm
I don't use network-manager in my setup (nor any desktop environment). I
do use WPA2.
as it doesn't look like anybody is actually working on this issue I'd rather
change the chipset.
Is there any other mini-PCI module, wireless-n Dual Band, non-Intel,
that is known to work properly?
