]]>你好请问下,我移植openwrt的时候,init那边内核panic了, 可以分享下你的移植么 Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004
看起来 WiFi AP 模式的速度较低还是,问题可能还是驱动或者 WiFi 芯片性能上。。
AP和STA模式都慢,这也太慢了,我之前用MT7601U作为STA,速度也能到30Mbps

ASIX 应该比较稳定,rtl8152b每隔一段时间,可能有十几天,就会断网,需要重新插拔。v3s跑openwrt 还挺合适的,期待楼主更多测试。
想请教下 V3S使用USB接LAN,速度能跑满吗?能跑到多少带宽?
我没用v3s测过,用的全志H3。
用iperf测过百兆网卡rtl8252b和千兆网卡ax88179。
百兆网卡可以跑满。
千兆网卡可以跑到300M,主要是受usb2.0接口限制,而且CPU使用率很高,相当于把四个核里的一个核跑满了,所以v3s更适合挂百兆,千兆的用途不是太大。
你这无线速度也忒慢了

用iperf3可以测试的。 openwrt里面可以直接装ipk

10 多块钱的百兆那种。。热的烫手。。。
性能好不好再说,先研究学习下,后续考虑试试 imx6ull 工业级的芯片
ASIX 应该比较稳定,rtl8152b每隔一段时间,可能有十几天,就会断网,需要重新插拔。v3s跑openwrt 还挺合适的,期待楼主更多测试。
想请教下 V3S使用USB接LAN,速度能跑满吗?能跑到多少带宽?
