Question USB Wifi Adapter in Aliexpress

[Tech9]

Ethernet wire is best (if possible, explore options), followed by internal PCIe card, followed perhaps by Wireless-to-Ethernet bridge, then USB adapter... but nothing really fits in $12 budget. I personally have used for some time only TP-Link T3U USB adapters, they are reliable, around $20. Work well in Win10/11, plug-and-play, okay range for such device (not great).

T3U of TP-Link not external antennas? IS bad?

I me reffer some wifi

 

[Tech9]

They have different versions. T3U is the small one with internal antennas, T3U Nano is even smaller with internal antennas, T3U Plus has external antenna, etc. I don't know what the real difference is in range and performance. I used this one:

AC1300 Mini Wireless MU-MIMO USB Adapter

Archer T3U USB Adapter delivers efficient AC1300 wireless connections with its SuperSpeed USB 3.0 Port. Dual-band for flexible connectivity. Mini-sized for convenient portability.

Which of these tplink models achieves the best performance and speed at a distance of 8 or 9 meters from the main router and with a wall in between? Are they all USB3.0?

 

[Tech9]

Most likely T3U Plus. TP-Link USB adapters with high-gain antennas are listed here:

I don't know what is available in your country and at what price. Ask around what works well.

For greater Wi-Fi reception (Mbps) on a USB adapter, is the antenna size, quantity antennas, chipset model, or Wi-Fi version (e.g., 5 or 6) more important? What is the priority sequence?

 

[Tech9]

In your case - AX-class, 2-stream, good signal. Physical antenna size doesn't matter in most cases, consumer Wi-Fi electronics have omnidirectional low-gain antennas, printed PCB or standard dipole. Chipset is usually some popular around release date Realtek. Not sure how to explain to you, but no one here can predict unknown adapter performance in unknown Wi-Fi environment.

 

[classic87]

My chipset is Realtek RTL8811CU and device use 4 little antennas
other usb wifi adapter two similar antennas and other chipset exemple RTL8812BU is superior or similar first adapter because uses two antennas and not four?

 

[Tech9]

RTL8811CU, 1-stream, up to 433Mbps link speed on 5GHz band, up to ~300Mbps throughput:

Realtek

RTL8812BU, 2-stream, up to 866Mbps link speed on 5GHz band, up to ~600Mbps throughput:

One more time - the NUMBER and the SIZE of VISIBLE antennas is IRRELEVANT to performance expectations. The cheaper the adapter the more likely antennas are just NON-FUNCTIONAL plastic so someone with less technical knowledge clicks on the "Buy" button. Most USB Wi-Fi adapters are made for CONVENIENCE and NOT performance, achieving maximum theoretical speeds is UNLIKELY.

This is my last post in this thread, someone else may want to help you further.

 

[classic87]

In this adapter with RTL8811CU chipset, does the positioning of the 4 antennas have any influence on Mbps loss or gain?

 

[degrub]

Usually no. There is no penalty for playing with them each time you move around.

What matters more is what is around the antennas or not around the antennas or what is between the antenna location and the AP.

 

[classic87]

Which of these USB Wi-Fi adapters can achieve higher Mbps reception (I'm not referring to the total Mbps it supports): both have four small 2 or 3 dBi antennas.
First adapter: uses a Realtek RTL8811CU chipset, 1300Mbps, Wi-Fi 5.
Second adapter: AX900 chipset Unknown, 900Mbps, Wi-Fi 6.
Both located in the same location, 9 meters away and one wall from the main router.
Which one will have higher Mbps reception?

router sends 600mbps

 

[degrub]

If router is only sending at 600, the receiver will only get 600. It won't matter which one is used.
If the router is wifi5 , you can use either the wifi5 or 6. If it is wifi6, then use the wifi6 adapter.

Time for you to buy one !
