@Enilyks 

Hi, for your issue, we would like to do the below troubleshooting to identify the issue first.
May I know the operating system of your computer? How about the driver for this adapter, did you install the latest one manually from our official website?

1.2Gbps is the 5GHz wireless speed, right? The advertised speed 2402 Mbps is the maximum negotiation speed for 5 GHz rather than the actual internet speed.

Your actual internet speed is influenced by the negotiation speed.

Can you please follow the instruction to check the wireless negotiation speed on the computer when connected to your router's 5GHz signal? 

https://www.tp-link.com/support/faq/2265/

Please change the router's 5GHz band channel to 36,40,44, channel width to be 80MHz to check again the speed.

Please do the comparison test using your other wireless devices in the same location as TP-Link wireless adapter. If they all have the same speed as TP-Link adapter, please make sure your router is running the latest firmware. 

Look forward to your reply.

@Kathy_Z I have the same problem where the download speed is about 400Mbps and upload speed is only 0.68Mbps. I have used this adapter on my PC for like 4 months and then this problem happens. I also have a wifi adapter on my motherboard but I prefer to have a wifi 6 adapter on my pc so I disable the mainboard wifi. When I turn it back on, the upload speed back to the regular speed that my house provides.

Any suggestions for this situation? (I cannot change the wifi adapter settings)

May I know the operating system of your computer? Windows 10? You may try to update the driver to be 22.0 then monitor the connection again:

@HieuChu same issue on my side... 0.73Mbps upload but on my laptop I have more than 39 Mbps, on the same place on the house and the same wifi network... 

@Kathy_Z

i just installed this device and am seeing speeds less than 10mpbs. 

- im using win10 64bit

- the status for negotiation speed when checking network connections is 117mbps

- driver info: date: 10/20/2020 version: 22.10.0.7

Have you tried my previous suggestions to HieuChu?

BTW, what is the bandwidth you have from the internet provider? You may connect the computer directly to the router or modem, test the speed by speedtest.

@AzraeL91  Hello,

For TX3000E ( upload)  speed slow issue, please make sure you've tried the Intel latest driver here: 

https://static.tp-link.com/beta/2021/202101/20210108/RTLWlanU_WindowsDriver_1030.41.0514.2020_Drv_3.00.0036(26078).zip

May I know does the issue particularly happen on 2.4Ghz/ 5Ghz band? 

Please let us know your computer motherboard information & driver date as this FAQ:  https://www.tp-link.com/support/faq/2722/

Please check the WiFi link speed on computer: (How to check the associated/link speed on a wireless client ) https://www.tp-link.com/support/faq/2899/

Did you try a different 5Ghz channel on router before, and what is the model of your router? 

@Solla-topee  Hello,

Thanks for responding to an old thread. I have installed the driver you sent over but unfortunatelly there was no improvement and my upload is still <10 Mbps (and >100 on other devices.

Regarding your other questions:

- It happens on 5Ghz band. I have 2 other devices connected to it in the same room and they do not have this issue.

- My motherboard is ASUS TUF GAMING X570-PLUS but I could not find the driver version. If instead you meant the TX3000E driver. It is 22.70.0.6 (although in my device manager, unlike in your FAQ, my TX3000E is labelled as Intel(R) Wi-Fi 6 AX200 160MHz

- I checked the link speed as advised and it is 866.7Mbps.

- I did try other 5Ghz channels but it did not help, and as mentioned this is not the problem on any other device. My router is BT Smart Hub 2.

Let me know if you need any extra information. Do you think the problem is with the TX3000E or the computer. Should I ask for a replacement?

i need driver Archer T3U Plus

Hi, 

 

I have recently purchased a TX3000E pcie card along with a AX6000 router. However, my pcie card does not seem to connect past 1.2Gbps when my old Asus ac66 had no issues at 1.3gbps. Being on the new AX I would expect faster connection speeds up to the 2.4gbps as advertised.

 

I am in direct line of sight to the router and only 6-8m between my PC and the router.

 

Any help would be appreciated.

 

Thank you
