我的 Lenovo G580 运行 16.04（或从可启动 USB 运行 18.04）时出现问题。如果我只是上网，一切都很好，但如果我使用 Deluge 或 Transmission 或 Youtube 下载，互联网就会冻结 1 到 2 分钟。如果我使用 Firefox 或 Chrome，那么我尝试使用的任何网站都会挂起，直到冻结期结束。我找不到类似的问题，因为许多“冻结”答案都需要重新启动，但这是每 5 分钟左右重新发生一次冻结的情况。“txop 超出”消息经常出现。
谢谢。
一些技术细节：

我建议你这样做：
sudo -i
echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
exit
重新启动并报告结果。
