Model: Archer A7  
Hardware Version: V5
Firmware Version: 1.2.0 Build 20211210 rel.56314(5553)

Issue:

provider (Spectrum) is giving 400~500 Mbps from the modem (verified by provider's technician), but Archer A7 is only giving 200~240 Mbps wired for lan devices (with Cat5e Ethernet cable from modem to router and router to laptop) and 140~150 Mbps for 5G wireless.

Note: the wireless adapter the laptop is using is Qualcomm Atheros QCA61x4A Wireless Network Adapter with peak speed 867 Mbps.

Note2: all internet speed test was ran on Spectrum's internet speed test website.

 

Current Settings (already rebooted after change):

Net Boost: enabled

Nat: enabled

QoS: disabled

Parental Control: disabled

System Parameter>Dulplex: 1000 Mbps full duplex

 

What setting I'm missing?

 

Edit 02/25/2024:

Recently there was something happened and my provider's technician had to re-route the entire coaxial cable from the switch outside of my apt.

I talked to this new technician about getting the wrong speed all the time, and he tested again after installing this new cable, it seems like the issue has resolved.

I'm not sure what he did, but I'm using the same modem and same router.

First step is to bypass the router and connect the computer direct to the modem to see the speed the ISP is providing.

Yes, indeed. I had the technician tested that using his device in front of me (he also tested the cables). His 17000 usd device also showed that I'm not getting the right speed from the router. I updated the firmware, restored the router to default settings, and then apply those settings after, but still failed the speed test. If this is the right settings I will cross my fingers and do hardware factory reset to see if it solves any mysterious issue like this.

Do the test with your own computer and Ethernet cable as both can be the issue as could the ISP.
