I am looking for a new PCIE wifi antenna. I currently have a TP-Link Talon AD7200 router. Ethernet is not currently a reliable option and the power line adapter solution (TP Link TL-PA8030P) is only providing a 180 Mbps connection while the router provides an almost 1 Gbps internet speed. I need a PCIE wifi antenna capable of handling online gaming, 4K video streaming, and music streaming. I am looking at the Rosewill RNX-AC1900PCE and TP-LINK Archer T9E as possible candidates, but I am open to suggestions on alternatives. Will either of these antennas meet my needs?

Here are the links for both antennas. Thanks.

Thanks - spec-wise (in terms of the radio modules), the USB-AC68 also does 3-stream MIMO at 600 Mbps max Phy on 2.4 GHz and 1300 Mbps max Phy on 5 GHz, same as the T9E and its red Rosewill clone. -46 dBm is pretty solid but improvable. 1300 Mbps is the best practical result you can get for Phy rate (256-QAM 5/6), 1170 would be just a bit lower in modulation (256-QAM 5/6).

The benefit of getting a T9E would be in upgrading the antennas, and in higher output...

Guess what? They're the same thing, just with different color and branding. Just look at the bottom of the page at https://wikidevi.com/wiki/Rosewill_RNX-AC1900PCE . Same FCC ID and everything. Rosewill is Newegg's house brand, like Dynex and Insignia for Best Buy. Same OEM makes both.

As requested in the other thread, please post your RSSI and link speed (Phy rate) using an app like Wifi Analyser, so that someone on the forum can tell you if higher receiver gain would help. You say you need to support real-time entertainment - well, we need to know if your RSSI is below -67 dBm to say what would actually help you.

I used WiFi Analyzer, I am not very familiar with all the settings and info. From the meter at the top, the line says -46 dbm, state hovers between 1170 and 1300 Mbps and link speed says 82% improved. The Wireless antenna that I am currently using is an ASUS USB-AC68.

The benefit of getting a T9E would be in upgrading the antennas, and in higher output power over the USB-AC68. First, you'd pick up around 5.3 dBm from the T9E's radio chains being stronger, so let's say your RSSI would increase to -40.7 dBm. The stock antennas with the T9E have 2 dBi gain which is actually about half that of the USB-AC68, but you can cheaply increase that to 12 dBi with some aftermarket antennas. Then you're up to around -32.7 dBm, potentially. It seems like that would be enough to modulate 256-QAM 5/6 pretty consistently, for about $68 total. And PCI-e on v.3 or higher is better than USB 3.0 for data rates on the computer.
