Wi-Fi slow but Ethernet fast? Compare fairly
A matched comparison can help show whether to investigate the local wireless connection.
Synthetic comparison
Invented example: two paired tests on the same Mac and server, minutes apart. These numbers are not customer measurements.
| Pair | Wi-Fi | Ethernet |
|---|---|---|
| 1 | 68 | 180 |
| 2 | 72 | 190 |
What to check
Use the same Mac and server. Run several tests close together, first on Wi-Fi and then on direct Ethernet with Wi-Fi disabled. Record the time and reduce background downloads.
What to do next
If wired results are consistently higher, Wi-Fi or the router is worth investigating. Different test conditions can also affect results, so this does not prove a particular cause.
