Speed comparisons: Wi-Fi USB versus Wi-Fi PCI-E
Speed comparisons: Wi-Fi USB versus Wi-Fi PCI-E
There are mixed reports about performance differences. Some claim PCI-E cards offer better speed, while others note USB speeds were slower in the past but now are more reliable. Your current setup shows modest downloads—around 20MB/s with a strong connection and 2MB/s with a weaker one. If your router is upstairs, realistically doubling speeds isn't guaranteed. Wi-Fi remains Wi-Fi, though powerline adapters didn’t help much for you.
The signal is quite weak. In any case, it's not reaching the full capacity I could achieve.
Many worries about hardware issues and low-quality construction come from the 1990s, but they might not reflect current technology. This is just one illustration.
It’s tough with Wi-Fi because so many factors come into play. It’s hard to pinpoint the perfect choice. We can only share what we’ve tried. My latest setup used a Netgear A6210 USB and a Tp-Link TL-WDN4800 PCIe adapter, both on Windows 10, tested with three different routers. The Netgear Nighthawk r7000 lived in a big house (friends’ place), the r6700 in a smaller home (my current residence), and the Sandynet router in both a small home and a medium-sized townhouse. Internet speeds were consistently 300/300 in all locations. The Netgear A6210 offered the fastest, roughly half the speed of the other two. In my own home, the combo gave me 300/300 with both routers. The biggest takeaway was reliability—Netgear A6210 performed best, with no drops and only occasional disconnects using the Sandynet router in the townhouse (though I don’t miss that one). The TP-Link 4800 was solid on some days but often dropped every few minutes or hours. Overall, USB adapters seem faster and more dependable. With so many options out there—different sizes, types, and setups—it’s impossible to say definitively. The best choice really depends on your needs. If you want peace of mind, consider buying from a store that lets you return items for a full refund if they don’t work.
They faced problems with a USB wireless adapter losing connection or operating slowly. After inserting a PCI-E card, the same issues arose. I tried a method I learned earlier to test its performance in this case. I bought a Wi-Fi repeater with two antennas and connected it to their home setup, running an Ethernet cable from it to the PC. The results weren’t very precise due to the 250MB connection limit, but it worked well—bursting to around 300 Mbps, wireless adapters around 85 Mbps (with drops), PCI-E about 95 Mbps (with drops), and the repeater with Ethernet reached 295 Mbps without interruptions. Now they could easily relocate the repeater anywhere as long as it had power. If they moved to another location, they could just bring it along and set it up for their desired network. For a desktop, it usually didn’t move much. The adapters used were standard Wi-Fi AC, while the USB and PCI-E ran between 900-1200AC, and the wireless repeater was around 750AC. It performed better with the Ethernet connection.
