opkg update提示出错，摄像头驱动安装不了

石头默

摄像头ID 1908：2311 GEMBIRD，路由刷成OpenWrt-DreamBox 20120201，源码修改如下：src/gz packages http://downloads.openwrt.org/bac ... 5/brcm63xx/packages
dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay
用grep usb也不能看到有input，明明已经联网了，却下载不了，老提示如下信息：
root@wificar:~# opkg update
Downloading http://downloads.openwrt.org/bac ... ckages/Packages.gz.
wget: bad address 'downloads.openwrt.org'
Collected errors:
* opkg_download: Failed to download http://downloads.openwrt.org/bac ... ackages/Packages.gz, wget returned 1.grep usb

查了好久都没解决，可是，换了个固件就好了
