Question Transfer problem on Intel AX210

[icrew]

Hello forum members I have a DELL Vostro 15 3500 laptop and I have replaced an ac card in it with an ax card (Intel AX210 card). I have a UPC 750 Mbps link. I have an ASUS XD6 router (the latest firmware) connected and a 5GHz 160MHz network configured. The connection between the laptop and the router is set at 2.4 Gbps, i.e. max. If I do speedtest, I get a maximum of about 500 Mbps, sometimes less. During the test, when I look at the set up connection, I see that the values drop from 2.4 Gbps to 1.4 Gbps, etc. What could be the reason why I only achieve this speed on this card? From what I saw on the Internet, people tested and achieved 900 Mbps calmly. The settings in the router are definitely OK. I have a laptop about 3-4m from the router in the same room, so there are no obstacles. I have the latest drivers for the AX210 card from Intel's website. Please give me a hint.

Are you connecting at 2.4Ghz or 5Ghz? 5 is faster.

 

[icrew]

5GHz of course.

So I will assume you are running directly to the main router and are not using the mesh unit. From what I read that is a 2 box mesh system.

You are actually getting more speed than your average person. You can't believe reviews. You have massive number of fake reviews and also have the people who like to wave their big "number" around.

The number are not actually speeds they represent data encoding methods and the exact number matters a lot. I suspect you are seeing 2402 and 1441.

All this means is the signal first attempted to run QAM1024 and the quality was not good so it dropped back to qam64. This is extremely common qam1024 pretty much only works if you sit on top of the router. It is such a scam I feel. You at least seem to be able to not be forced back to 80mhz radio bands which is extremely common. When you attempt to use 160mhz radio bands you pretty much garantee that you overlap your neighbors radio signals.

This is why wifi6e should be better....for a while until everyone starts to use it.

Be very happy if you are getting 500mbps that is much higher than a lot of people that are trying to run wifi6 on the 5g radio band.

This is the table that show you want those numbers really mean.

Your numbers look correct, your client device only has a 2x2 radio. In order to achieve 2.4gbps you need a 4x4 client.

So for a wifi 6 non-E 2x2 client at 5ghz, your connection speed is likely 1200mbps. But since wifi is half duplex, your actual download speed will be about 600mbps.

However, 5ghz is really crowded and 160mhz is unadvisable on 5ghz. I'd recommend you stick with 80mhz channel width or you'll get occasional dropouts in my experience.

If you want to use 160mhz channel width, you need to move to a Wifi 6E router and run at 6ghz. Then you'll get your full 750mbps speed.

Ok, but the connection is 2.4 Gbps.

Ok, but the connection is 2.4 Gbps.

The problem with 5ghz is that they use a weird 80+80mhz arrangement to achieve 160mhz. There may be a complication here between your router and client.

5ghz and 80mhz with a 2x2 client will give a connection of 1200mbps.

5ghz and 160mhz but at 64 QAM will give a connection speed between 1152mbps to 1441mbps depending on the channel.

You need all the stars to align at 5ghz @160mhz channel width and 1024qam to get 2400mbps.

Stop believing fake marketing numbers. That is not a speed I posted the table of what the numbers mean it seems you just want a easy answer.

The marketing guys are being extremely deceptive in many ways. They would call a ethernet cable 2gbit because they add transmit and receive speeds but a ethernet cable can actually send 1gbit and receive 1gbit at the same time. Wifi is half duplex so only 1 device can transmit at a time.
They are doing all kinds of stuff like ignoring all the error correction/detection overhead in the packets that the end user can not directly use.

Again be very happy you are getting up to 500mbps. Huge numbers of people buy wifi6 and then discover they get about the same 300mbps maximum they were getting with 802.11ac.
