Why does LAN speed change from 100 Mbps to 10 Mbps?

On the right-bottom corner, it shows the LAN status, which is 10 Mbps (10baseT full Duplex ) or (10baseT half Duplex)at once, after I disconnect the network and reconnect it, it would back to 100 Mbps. (100baseTX full Duplex)or(100baseTX half Duplex)

Would it be a sign of hardware failure?

Does anyone have any suggestions?

Thanks in advance for any suggestions :>

Most network "cards" auto-negotiate a connection speed by default. This can be set to whatever rate you want via the properties of the "card" in Device Manager. However, my understanding is that this might result in unreliability if there is a hardware problem.

Try a genuine Cat 5e Ethernet cable first before attempting to set the speed manually. A genuine Cat 5e cable will have exactly that written on it. Note that Cat 5 is not Cat 5e.
