Sorry for the late reply, I was travelling the past days. 

1) No LAN Devices at all. Only the WAN Port is pluged with a Cable from the "Vodafone Box" to actually get a internet connection. It did not matter if someone played any games, or downloaded large files. When I played Rocket League for example, I saw the same jumps in the same ratio as if I would go through Google. 

2) 

This is basically an example for 4 different WLAN adapter/cards used. This one being the slowest with the shown 780 Mbps (Intel Wireless AC 9560 160Mhz). But my external Realtek WLAN Adapter shows similar, just with 866 Mbps (a Adapter with a Realtek Chipset). Still, only the explained 200 Mbps of the actual 1 Gbps Internet connection are coming through at max. Some weeks ago I actually was able to get ~300-400 Mbps, but back then I didn't notice any spikes with the CPU for example either. 

3) 

The Negotiation Speed shows 1000 Mbps full duplex for the WAN port. 

Using an CAT 5e cable also results in a Negotiation Speed of 1000 Mbps full duplex.

^ Doing the Speedtest with the Ethernet cable, leading to the same outcome. 

^ This one is with the WLAN Adapter (any basically) 

@Solla-topee I have the same behaviour on my ARcher C7 V5, I get this jittery ping that jumps out of <1ms while in low CPU Load and goes to 300ms or more when it reaches 99% This is extremely annoying and it does that with or without devices connected, doing nothing but receiving internet. This makes the device practically unusable.

Did the team you escalated this to find a solution?

I am on FW: 1.1.0 Build 20201120 rel.50406(5553) 

No printer, no USB, nothing weird going on. 

@Solla-topee Exact same problem CPU load jumps to 100%. Let us know what is the status on this issues. Thanks! 

I have same symptoms:

- CPU Load jumps from ~2-4% to 100% every couple of seconds regardless of network traffic or amount of devices connected

- Constant connectivity drops on 2.4GHz access point (5GHz connection seems fine)

- Slow wireless speed.

I do have the same symptoms as above, but my individual problem is due to router 'overheating', mine is set up in a relatively confined area with poor ventilation, taking it out of that space or fanning in some air helps cool it down - my CPU load hiccups on a router are gone. Looks like CPU throttling.

I have never had this problem with routers of different models over the years, this is the 1st one that sits in the same spot and overheats. 

And it is not really that hot' - the case is pretty warm to the touch but it's definitely not 'burning hot'.

I'll probably take it apart and see if I can add some active cooling to it. Too bad, there is no temperature output on the router's system page.

Again, it's possible this is not the same problem as others having.

Has this been sorted am having same problem..

Also it having regular disconnection.

It annoying

Hello, 

 

I constantly have problems with my Archer C7. The CPU load shown in the UI of the router repeatedly jumps to 90-100%, then back to 2-5%, back to 40-60%, back down, repeat...

 

These 90-100% jumps are also bound to some connection issues. 

 

Also, my Archer C7 never put through the 1300 Mbps through 5 Ghz. It maxes out at ~220 Mbps most of the time. My adapter would allow for 866 Mbps, so I'd at least think it would get at least up to 500 Mbps from my 1 Gbps internet connection. 

The Internet port on the Network Page shows 1000 Mbps full duplex, so it shouldn't be a problem of the cable. Testing my Internet speed to the box from Vodafone (set to bridge mode) also shows 1 Gbps consistently. I feel like the CPU jumps are causing not only the connection timeouts, but are also responsible for the low Mbps throughput in the 5 Ghz topology. 

 

Maybe someone can help me with this problem? :)

I added a noctua fan under the router to cool it - no issues now.
