mt7620n trunk上的无线驱动bug

qianguozheng · 发表于 2014-8-18 10:55

使用最新openwrt trunk上编译出的ZBT-WA05.bin，跑起来之后长时间运行会出现以下dmesg,这个时候STA无法和AP建立连接。
有没有人遇到过同样的问题呢？

只有重启才恢复正常。

wifi 设置的高级设置，HT Mode是不是选择了40MHZ？

lintel · 发表于 2014-8-18 14:50

打上这个补丁试试.

恩，补丁已打，准备测试下。
这个文件里 compat-wireless-2014-05-22/drivers/net/wireless/rt2x00/rt2x00queue.c 要不要做相同的修改？

打了你的补丁之后，把这个文件也按照同样的方式做了修改compat-wireless-2014-05-22/drivers/net/wireless/rt2x00/rt2x00queue.c 。
仍然会有同样的dmesg出现，但是这次没有上不了网的情况（之前也有过类似的情况），我会继续摆着跑长期测试看看。

打上这个补丁试试.

打上补丁后，会出现 ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 这样的dmesg, 有两次大量出现。且后来路由器有重启。

打上这个补丁试试.

同样的问题出现，无线无法建立网络连接，看来这个补丁，没有起到应有的作用啊。

各位大神，这是个学习的机会啊，证明你实力的时候到了，快来试试身手吧，类似的问题在很多ralink的芯片上都有，解掉这个bug,我相信，您肯定会有所提升。

我用的是dlink的615d4，这个问题不定期出现，简直烦透了，似乎ramips无法摆脱这个问题
后来换了ddwrt，似乎还没出现过，但功能少了不少了
