Just upgraded our router with a 802.11N(Netgear N300. The other laptop is now connecting at 300Mb, but this one stays around 50mb. I did see it up around 68mb once.

And here it is sitting next to the router, a bit faster
| Code: | cory-netbook cory # iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:"NETGEAR"

I tried forcing it, but that had no effect.
| Code: | iwconfig wlan0 rate 300M
|
Any suggestions? Or should I be in the hardware section?
Thanks
Cory

probably the NIC is getting downgraded from using n to using g for some reason, i would assume a configuration error?

Possibly, I added support to the kernel config for the brcmsmac module and emerged the firmware. Installed the module and set up the connection with nm-applet. I just read though manual configuration of the wireless and don't see anything different than through the nm-applet.
Unfortunately, I have no idea where else to look. Wireless has always 'just worked' before, I'm far from a expert.
Thanks
Cory

| I'm also having the same problem. I found that net-wireless/broadcom-sta works with 802.11n, but I'd rather/like to use brcmsmac... I've been trying to find the right configuration for a whole week already, but no luck so far. : ( I'm using kernel version 3.3.4 ) |

| 60Mbps is beyond g speeds, so I'd assume it's a signal strength thing. Try changing the channel a few times? |

@Dark Shoyu, the brcmsmac driver was found in:
Device Drivers -> Networking Support -> Wireless LAN -> Broadcom softmac driver (or something very similar to this)
in the kernel menuconfig .
As of kernel 3.3.4, it seems to have disappeared somewhere else, though, however . But you could give it a shot and rebuild the kernel with brcmsmac as a module, then load it upon reboot with modprobe .
I am trying to rebuild the kernel with brcmsmac but I can only seem to find the brcmfmac driver, which is not the one that I need .
Anyhow, good luck, and if you do manage to find "brcmsmac" in the kernel 3.3.4 menuconfig, do let me know of your findings please ! (: |

It is still there, but you have to enable it's dependencies. Make a search in menuconfig with / on brcmsmac, and it will show you what it depends on. |
