[問題] BeagleBone Black如何同時無線SSH與上網
最近我拿到了一塊BeagleBone Black (以下簡稱BBB)
我照著網路上的教學，用USB線ssh進了BBB的root
也在BBB的USB插了一張無線網卡D-LINK DWA-121，成功了連到了我家的router上網
root@beaglebone:~# ping www.google.com
PING www.google.com (74.125.203.99) 56(84) bytes of data.
64 bytes from www.google.com (74.125.203.99): icmp_req=1 ttl=47 time=17.3 ms
64 bytes from www.google.com (74.125.203.99): icmp_req=2 ttl=47 time=17.6 ms
但現在我想用無線的方式ssh進BBB，同時BBB也要保持連到我家的router上網
大概像這樣：筆電 <---經由無線ssh---> BBB <---DWA-121---> 外部網路
所以我就拿了一台Asus WL-330N插在BBB的RJ45
做了一些設定之後也成功的ssh進了BBB的root
但是ping了google卻沒有反應。我查了網卡的組態，卻看不出要從何下手...

我只知道eth0是RJ45，wlan0是無線網卡D-LINK DWA-121
請問要怎麼做才能同時無線ssh又連上無線網路上網呢？

我發現當WL-330N跟D-LINK DWA-121一起插的時候
只看得到WL-330N，routing table沒有出現wlan0
所以我就試著直接用WL-330N同時連上網路，且連上電腦做SSH
結果就成功了！！
現在長得像這樣： 筆電 <---無線SSH (WL-330N)---> BBB
