Slackware：无线速度真的很慢

问题：我的无线网络运行在 11Mb（原文如此！）上，我使用的是 slackware 14.1

iwconfig 说

wlan0     IEEE 802.11bgn  ESSID:"ops!"  
      Mode:Managed  Frequency:2.472 GHz  Access Point: ops!   
      Bit Rate=11 Mb/s   Tx-Power=15 dBm   
      Retry short limit:7   RTS thr:off   Fragment thr:off
      Power Management:off
      Link Quality=32/70  Signal level=-78 dBm  
      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:3  Invalid misc:52   Missed beacon:0

这是 rc.inet1.conf

#WLAN_ESSID[4]=BARRIER05
WLAN_MODE[4]="Ad-Hoc"
WLAN_RATE[4]="54M"
WLAN_CHANNEL[4]="auto"
WLAN_WPA[4]="wpa_supplicant"
WLAN_WPADRIVER[4]="nl80211"

我设置了 Ad-Hoc，因为我在某处读到 54M 仅在“Ad-hoc”模式下才可能。

这是卡的 lspci 输出

当然路由器支持超过54M（是300M路由器）没有办法得到54M？谢谢
