![如何修复 Aspire V5-571 上 13.04 版本的 Wifi 问题?](https://linux22.com/image/1114929/%E5%A6%82%E4%BD%95%E4%BF%AE%E5%A4%8D%20Aspire%20V5-571%20%E4%B8%8A%2013.04%20%E7%89%88%E6%9C%AC%E7%9A%84%20Wifi%20%E9%97%AE%E9%A2%98%EF%BC%9F.png)
昨天我从 Ubuntu 12.10 升级到了 13.04。我非常喜欢它,直到我意识到无线连接只能持续大约五分钟,然后就无法使用了。我到处搜索,最后尝试了这个和这个。什么都不起作用,所以我最终恢复使用 12.10,一切又恢复正常了。我现在很想使用 13.04,所以我寻求帮助来解决这个问题。
这是我重新安装 12.10 后获得的一些系统信息,如果有任何其他信息有用,请告诉我。谢谢!
