Have trouble setting up the new Wi-Fi card?
I recently purchased the tp-link archer t9e but it isn’t performing as expected. I’m using BELL fiber optics on a 1.5 Gbps plan and only achieving about 10-20mbps download speeds. The card’s advertised speed is around 1 Gbps. Additionally, the Bluetooth audio quality drops when my headphones are connected.
You're likely dealing with different measurement units. The speeds you hear about are usually in bits per second, while your device might display bytes per second. A typical WiFi 5 connection can reach around 500-600 Mbps, which is about 10-20 MBps. A WiFi 6 card would probably fall short unless you're using a very strong signal. Just because your connection is fast doesn't mean you'll be downloading huge files instantly—many online services limit their bandwidth regardless of your connection speed.
These rates are only measured in controlled settings. In everyday use you could receive only a third of the intended performance. The difference is likely due to interference. Be aware that 5GHz offers higher speeds but doesn’t match the coverage or reach of 2.4GHz. The focus is on 5GHz for maximum velocity. Also note the specifications listed on the device are for both 2.4 and 5GHz frequencies combined. You should verify the ratings for each band separately since you connect one at a time. Consider the placement of your antennas relative to the router—factors like your computer’s enclosure or solid structures such as concrete and brick can disrupt signals.
The TP-LINK Archer T9E uses a WiFi 5 (IEEE 802.11ac) chipset powered by the Broadcom BCM4360. Expect improved speeds compared to 20mps, with 60 to 90 mbps being a typical range. However, several factors influence performance. Distance from the router matters, as does the presence of obstacles like walls or solid structures (such as brick or concrete), which can block the signal and reduce both sending and receiving capabilities. Metal components, like a PC case, can also interfere with the signal. If your PC case is in line-of-sight to the router, signal strength will be affected. Adjust your PC orientation so the antenna is closer to the router for optimal testing. Signal-to-noise ratio (SNR) plays a role too; in busy environments with many devices using WiFi simultaneously, interference increases. Think of it like shouting in a noisy concert versus a quiet room. Lastly, orientation isn’t perfectly circular—WiFi coverage tends to be uneven due to antenna design. Using both 2.4GHz and 5GHz bands can help, so experiment with them to find the best fit for your setup.
You can achieve speeds near 700Mbit with the right setup but only if your router offers 3x3 MIMO on 5GHz with an 80MHz channel width. Ensure your PC and router are in the same room, with no obstacles between them. The issue often lies in the PC case blocking the signal or the lack of an external antenna designed to sit on top. Your headphones may also suffer from choppiness due to similar interference. What router model do you have?
