TP-Link AC1200 dual band router speed is only 94Mbps

Huh?
Adept
I have a ACT connection with 400Mbps speed connected to a TP-Link AC1200 dual band router. For the past few days I get a connection speed of 94Mbps only instead of the 400Mbps. I checked with the ACT ISP and they said that there is a fault in my router and it needs to be flashed. They told me to take the router to the service center to do that. Sometimes I get the full speed of 400Mbps when I switch off and switch on the router but this happens occasionally but after complaining to ACT I got the full speed for a day or two and now again back to 94Mbps speed. How do I find out if this is really a router problem or the ACT service guy is bluffing and capping the speed?

1. Make sure you are connected on 5GHz mode. Disable 2.4G for the testing.
2. Use WiFi analyzer to identify best available channel, configure manually. (Since you said, power cycle improves speed, when you powercycle, in auto channel selection mode, router pick the best available channel. Later the channel might be most used in your neighbourhood)
3. Try running speed test between wireless device to LAN connected device.
 
It. Would be both
First up reset your router
Download and flash the latest update again
Set it up and see

In my experience it's always the isp, there are far too many variables at their end starting from the cables, ont device and connections both local and at the pillar..

As them to send a technician and get him to check and show the parameters of attenuation and I am fire getting the second one..
 
I would recommend testing over ethernet to eliminate wi-fi connection as a failure point.

Also, you can try connecting ACT's ethernet cable directly into your PC's ethernet port to completely eliminate your router as a factor.

1. Did that
2. No improvement, same speed
3. No improvement here also

Reset the router and upgraded to latest firmware. Same speed. Will check with the isp again.

Is it a fibre connection or the ethernet wire comes directly to your home?

It is a fibre connection directly connected to the wireless router and a LAN connection to the desktop.

I directly connected the ACT ethernet cable to the desktop LAN port and still it has the same speed. The desktop has a Gigabit LAN port. So most probably the router is working properly and maybe the ACT guys are throttling the speed or there is some technical problem at their end.

Based on your statements, it is amply clear that ACT is at fault. They could be throttling your speed. How else would your speed jump to the advertised level of 400Mbps.
My simple advice is contact ACT and tell them you are connecting your MAIN device (PC/Laptop/TV) DIRECTLY into the ACT's on-premise device. If ACT is offering connection through a standard LAN Cable, then tell them you use only ONE device and THAT device is showing 94Mbps.
This seems like a case of poor management of connections. Most likely, your router is fine.
As you confirmed it is a Fiber connection, it will either terminate to an ONT or it will be converted to RJ45 (LAN) and connection would be distributed via a "Switch". Either ways, this should be rectified by ACT.
 
So one of the ACT engineer came and he also kept saying that the router is at fault and wanted me to get a new router. I asked him to connect the fiber cable directly to the system and check and then he was not able to give any reason why the speed is getting throttled. He went back and after couple of hours called me to check the speed and I got back the 400Mbps speed. He said the problem was at a junction box and a switch was at fault and it has been rectified now. I asked him why he told my router was at fault before even checking at his end, he simply said he was sorry and blamed another service person who had said earlier that the router was fault and he blindly believed him. If not for all of the FM's suggestions especially @gourav who suggested to check the connection directly with the system, I would have bought a new router believing these ACT guys.

In India never blindly believe anything the technical support of any service provider say unless they are getting a salary of at least 1 lakh per month (based on the logic that this is what real technical personnel at backend should get).

Have faced similar issue and in my case, I did end up buying another router (which is currently listed for sale, lol). In my case, the connection kept dropping. I called them multiple times, but they wouldn't accept it was a fault with the connection. I asked them to provide a temporary router which they said they don't have.

So I bought a cheap router. The issue persisted. So I yelled at them and they finally actually checked. It was a simple case of bad crimping of the LAN cable. Once those guys redid the crimping, the issue never occurred again.

This was local cable guy, not ACT.

Fun fact, a few months later, rats chewed the LAN cable outside my house. Those guys asked me to pay for a new cable. No matter how much I fought, they refused to change the cable. I too didn't relent and switched to Airtel instead, even if it meant going a full month with no broadband, only mobile hotspot.
