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?
