Question Will I experience noticeable improvement in performance if I upgrade the WiFi of my PC to 6E with a new fibre 1.5Gbps router-modem?

Hello, my ISP upgraded my home internet from copper to fibre 1.5Gbps. The router-modem is using Wifi 6E.

My DIY PC has the following motherboard:

Z390 AORUS XTREME (rev. 1.0) Key Features | Motherboard - GIGABYTE Global

Lasting Quality from GIGABYTE.GIGABYTE Ultra Durable™ motherboards bring together a unique blend of features and technologies that offer users the absolute ...

1. Intel® CNVi interface 802.11a/b/g/n/ac, supporting 2.4/5 GHz Dual-Band
2. BLUETOOTH 5
3. Support for 11ac 160 MHz wireless standard and up to 1.73 Gbps data rate
   * Actual data rate may vary depending on environment and equipment.

Is there any point to add a Wifi 6E USB adapter to my PC? Will there be noticeable difference in performance? Even with copper, I did not experience any lag when watching youtube 4K videos. I may add a NAS at home few months later.

There are a lot of factors that go into wireless speeds. The wireless device is just one of them. What kind of speeds do you get with your existing equipment?

iPhone with Wifi6E got 1065.6Mbps download and 1022.1 Mbps upload.
For my desktop PC mentioned above, it got 419.8Mbps download and 428.6Mbps upload.

Ok, is that good enough for what you use the PC for? That's easily good enough for YouTube, even at 4K. The only benefit to faster speeds than you're getting is downloads or possibly file transfers over the network.

If you do get a replacement I think I would look at a PCIe version rather than USB.

For the time being, that is good enough but in a few months, I plan to buy a NAS so I wonder if it is a good idea to upgrade the Wifi of my PC while components are on sale.

Given that the ISP service I subscribed for is 1.5Gbps but I only got about 1Gbps. Is such a big difference normal?


Currently two PCIe slots are occupied by Nvidia RTX2080Ti.
Also, given that the PCIe in the motherboard is old, is it still better to get the PCIe version of Wifi 6e or perhaps Wifi7?

1. 1 x PCI Express x16 slot, running at x16 (PCIEX16)
   * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
2. 1 x PCI Express x16 slot, running at x8 (PCIEX8)
   * The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot operates at up to x8 mode.
3. 1 x PCI Express x16 slot, running at x4 (PCIEX4)
   * The PCIEX4 slot shares bandwidth with the M2P connector. The PCIEX4 slot operates at up to x2 mode when a PCIe SSD is installed in the M2P connector.
   (All of the PCI Express x16 slots conform to PCI Express 3.0 standard.)
4. 2 x PCI Express x1 slots
   (All of the PCI Express x1 slots conform to PCI Express 2.0 standard.)
5. 1 x M.2 Socket 1 connector for an Intel® CNVi wireless module only (CNVI)

You need a wifi router with 3gbps bandwidth to max out the speed. Who needs that? The phone and or wireless NIC card must be able to push 3gbps wireless. I doubt any NIC card can do those speeds. I think the max speeds for wifi are around 1gbps. I am sure there is pro gear out there that could do it but that will cost a lot. More importantly you need a tri band setup to eliminate lag on your devices.

I would say real world 600-800mbps is optimal for Wifi 6e. That is plenty fast for anybody's needs. If you want the full speed, Cat5e or Cat6 wired is the way to go. You have to make sure your devices all have a 2.5gb ethernet ports for wired connections.
