如果我使用运行 10.10 的新 Thinkpad Edge 15 离我的接入点超过几米(并且我在各种 AP 上都看到了这种情况),那么 wifi 性能就会变得……不稳定。发生这种情况时,我会在 中看到以下内容dmesg
,尽管我不确定它是否相关:
[ 2497.011099] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded

关于我的无线适配器有以下要说的:

如果我在接入点几米的范围内,我仍然会在 dmesg 中看到该输出,但连接会稳定下来。
我的问题有三个:如何获得更好的 wifi 范围,我可以/应该对 dmesg 中的这些消息做什么,最关键的是,这两者是否相关?
一如既往,让我知道是否有其他信息会有所帮助!
编辑:我在与我以前使用运行各种旧版本 Ubuntu 的 Thinkpad (T61) 完全相同的位置使用这台机器,所以我肯定觉得有问题,而不是我对范围有不合理的期望!
