@NitinKumar  disable QoS (set to 0) for  2.4 Gbps connection.

@hyun QoS was never active as I did not use TP Link ID with the router and without TP Link ID, the router does not allow QoS and HomeCare.

I have also seen the max Ethernet speeds be around 700-750 Mbps when using my Gigabit connection from Cox. Plugging directly into the modem gives me the advertised 940 Mbps. Wonder if there's a fix/tweak or am I stuck with a crippled Gigabit connection on the router?

@afilen I have tried AX3000 and return it, then I tried Tp Link AC2600 and return it too because it too gave lower ethernet speed. Now, I am back to a D Link Gigabyte Switch which gives me around 950 Mbps speed. So no wireless solution but if you need to connect your system with a wire, I think switch will outperforms router with gigabyte routers anyday.

@Kevin_Z Please refer to my original post where i have provided all information and then read the post of other user who is describing that he has same problem, connect the two information and then you don't need to ask the other user all information. There shouldn't be a need to ask the information again and again in the same thread. In short, ethernet ports are not giving us close to 1 Gbps while 1 Gbps Switch can. Either Tp Link 1 Gbps ports give close to 1 Gbps (around or equal to 950 Gbps) or they don't, if they do please ask your technical team to confirm it as why we ain't getting those speed. I am a very old customer with house full of Tp link products. There shouldn't be beating around the bush.

I'm having issues with the ax50 dropping absolutely everything wired and wireless. Just put it in last night and it rebooted itself once after about 4 hours and several times throughout today. Why are ALL of the vents on the bottom? I'm flipping the thing over to see if that helps. If this is the fix I'll have to mod the damn case to open it up so it can vent heat. Whoever designed this thing should be fired.

Really dissapointed in this product, and even more so the awful "support".  

This article clearly states "All TP-Link routers support VPN Passthrough for PPTP, L2TP and IPSec (ESP)."

https://www.tp-link.com/us/support/faq/558/

But, it does not work.  6 hours now dealing with support, and I don't even think they understand what I am trying to do-  They keep telling me to click on Advanced-> VPN  (A link does not exist)..  Ok, Advanced -> VPN Server..   NO!  I don't want the AX50 to be the endpoint, I just want it to pass the VPN traffic from the computer!

Reading online, it may be related to a QOS setting called "NAT BOOST".  However, the new UI does not give me the ability to access the QOS page.  Instead, I have to install an APP on a mobile device?   Not going to happen!   I should not be required to use an APP to configure the router.  

Thankful for Amazon good return policies, this one will be going back.  Won't conider replacing it with another TP-LINK device because support is so awful.

I'm having exactly the same issues that you are describing.

To force 2.4Gbps, I have to set the 5Ghz channel to 108 (DFS). It works for a while, then it auto changes the channel back to whatever it wants, and the speed is capped at 1.2Gbps. If I try to set it back to a DFS channel (the only ones that gave me 2.4Gbps so far), it sometimes hangs the router and needs a reboot.

Even at 1.2Gbps, the wired speed is lacking, so your "1.2gbps" are useless. When sending data to my NAS, it goes at about 350mbps. Receiving from the same NAS it goes at about 700-750mbps (the NAS is also connected to a 10GbE switch, and can saturate 10gig).

So, WIRED speeds:

Tx: 350mbps

Rx: 750mbps

Nearly 2021 and this thing can't even manage 1gpbs wired right?

I have the router set in AP mode, I don't need it as a router. It is quite basic. It doesn't even support tagging VLANs. When TP-Links states that it supports "VLAN Tagging" it means it can freaking pass a packet that has a tag. What an achievement!

It's a POS, honestly. I regret buying it. It's swarmed by bugs, the AP mode is nearly useless (you have to connect the WAN port like an uplink, or something, instead of creating a bridge with the 5 available ports. When connected to another port it didn't want to pass DHCP traffic, that is managed by another equipment in my network. I really can't confirm this, 'cause it's buggy as hell, so... maybe it was just that one time).

Oh! But it has an app for the smartphone, with icons and stuff.

The intended audience of this thing is someone who will never test if it can actually work at advertised speeds.
