Which model of the WRT54G do you have? https://wikidevi.com/wiki/Linksys_WRT54G_series Is it running the vendor firmware or some other such as OpenWrt? All models of the WRT54G are slow by today's standards, and are likely to be a bottleneck for network throughput, even at such moderate bitrates. This doesn't explain the difference between the two clients, though. > On the desktop, I am using "Panda Ultra 150Mbps Wireless N USB > Adapter" <https://www.amazon.com/gp/product/B00762YNMG/> to connect to > the router. > > The laptop has a builtin wifi adapter, Intel(R) Dual Band Wireless-AC 8265. > > The desktop is running Debian stretch. The laptop is running Windows 10 Home. I'd suggest plugging the USB adapter into the laptop and comparing the throughput of the built-in adapter vs. the USB one, by enabling each of the wireless interfaces in turn and disabling the other. Repeat the test with a linux live system, also on the laptop. This should reveal whether the USB wireless adapter is the bottleneck. Which frequency band / channel are you using? The USB plug seems to be physically small, without enough space to fit a reasonably-sized 2.4 GHz antenna. It might work better on 5 GHz, but I am not aware of any linksys wrt54g model which supports this band. Regards Mirko
