【hx801217】 在 https://github.com/istoreos/istoreos/issues/990 发布：
之前搜索了issue，关于8168使用8169驱动，后来大大提供了驱动，我看他的问题也解决了。
但是我的问题跟他的不同，我因为是办公室百兆网，一直降速使用，从0609升级到0901之后，反应的是flow control off，也就是光有链接，但不走数据，ap无法访问，wifi无连接因特网问题。
1.关于你要提交的问题
为避免重复issue，请先搜索issue，确认没有类似issue再提交新issue；
注意搜索时包括已关闭的issue（删掉搜索框的的“is:open”条件）；
Q：是否用关键词搜索了issue? (使用 “x” 选择)
- 没有类似的issue
2. 详细叙述
(1) 具体问题
A：8168网卡降速使用，升级22.03.05之后，表现为不走数据，ap无法访问，wifi无连接因特网。
(2) 路由器型号和固件版本
A：hp t620 thinpc，固件版本0910
(3) 详细日志和/或截图
A：网络基本信息：
