I get unusably slow network speeds on my HP 8530W laptop when connected via Ethernet. Here are the results of some unscientific tests, comparing throughput reported by Windows while copying a 130MB file from a local server, Wifi vs Ethernet and this laptop vs a similar Dell laptop in the same room.
- HP 8530W (WiFi) 1.9 MB/sec
- HP 8530W (Ethernet) .0046 MB/sec (4.6 KB/sec)
- Dell (Wifi) 1.5 MB/sec
- Dell (Ethernet) 12.2 MB/sec
HP has sent out a technician to replace the Ethernet adapter, which involves replacing the entire motherboard, twice, with no improvement. So I'm pretty sure it's not the hardware.
In the tests above, both the Dell and the HP are using the same physical cable, same hub. So I'm pretty sure it's not the network.
That only leaves software. But this was happening before I did a clean install of Windows 7, and it's still happening. The laptop is running the latest BIOS, and the latest drivers for the Ethernet adapter.
So what could the problem possibly be?
