Unmanaged witches for the consumer market tend to last fewer years than they |
| 19 |
used to. This is because their power supply as well as the components on the |
| 20 |
circuit board are now manufactured as cheaply as possible. Good for repeat |
| 21 |
sales, bad for the consumer. |

The switch may fail outright, in which case the network fault is obvious. Or, |
| 24 |
it may start failing intermittently. Typical failure modes are for one or |
| 25 |
more ports to stop working altogether, or downgrade the port speed - as |
| 26 |
observed by the OP. Removing the ethernet cable, powering down the switch, |
| 27 |
re-inserting the ethernet cable and powering up the switch may restore the |
| 28 |
correct operation on the port. |

It was usually the case electrolytic capacitors on the circuit board could be |
| 31 |
replaced to fix the switch, but more recently some manufactures no longer use |
| 32 |
electrolytic capacitors - so I'm not sure repairs are even possible. |
