Review on Wi-Fi adapter TP-LINK Archer T4E, green by Kiyoshi Goro ᠌

Approximately as the human brain is used, usually, by 5-10 percent of possibilities under normal conditions, so this device - A WiFi adapter running on a very fast PCI-E interface "squeezes" a few percent out of this interface. To start using the brain more intensively, a person must get into a stressful situation, or train for a long time. What this miracle of technology needs to somehow accelerate, I could not guess. "Native" drivers were delivered, of course. Without them, this is generally a stub for the slot. No dancing with a tambourine could make the Archer T4E "see" 5 GHz channels, except for 36 and 40. You can forget about auto-tuning the 5 GHz frequency on the router. When you turn it on, the adapter regularly loses 5 GHz. Although, even if you manually select one of the "working" channels 36 and 40, you still won't be able to enjoy the high speed of access. It will be lower than 2.4 GHz, almost guaranteed. Replacing the complete antennas with a remote one did not give anything. I took the antenna from the Asus motherboard (works in another PC). Nothing has changed in terms of signal reception and network access speed (speedtest. Net), at 5 GHz it became even worse, but more stable (paradox). The antenna connector farthest from the PCI-E connector is generally similar to an imitation. Screwing or unscrewing the antenna from it does not change anything. In fact, the presence of an antenna only affects the first, closest to the PCI-E connector. Don't buy this, don't be fooled like everyone here has done. Better buy a USB whistle.
