Model: Archer C6  
Hardware Version: V2
Firmware Version: 1.3.6 Build 20200902 rel.65591(4555)

I bought an Archer C6 (eu) V2 from Amazon India and started using it a day back. However, I am facing an issue wherein the download speed drops suddenly and recovers after a few mins. My bandwidth provided by my ISP is 30 Mbps but sometimes the speed drops to 2 Mbps and I checked plugging in an another router so as to rule out the problem with the ISP, but the speed is fine with other router. This issue is happening on all the devices connected to the 2.4ghz band on Archer C6. The current firmware version which is installed is 1.3.6 Build 20200902 rel.65591(4555) and there are no updates available via OTA. Also, the ping time becomes very high and also cannot login to the router admin page during this time. However, it becomes normal within a few minutes. Is there any way to fix this or should I just return this product?

@Kevin_Z I tried updating to the beta firmware but still the issue persists. The speed is occasionally dropping to 2-3Mbps and after a couple of minutes or restarts it goes back to 20Mbps. Also, while turning on the router, it takes almost 8 minutes for the internet lamp to turn green from orange.

@Vasudev 

 

Hello, thanks for getting back.

 

When the 2.4GHz internet speed drops to 2M, how about the link speed on the computer when it connects to the 2.4GHz? What is the link speed when the internet speed is normal? Please show us the screenshots of the link speed.

 

How many devices are connected to the 2.4GHz network, are they getting the slow speed at the same time? How many devices are connected to the 5GHz and wired? Are they always normal?

 

Try to modify the wireless basic settings as I mentioned earlier, such as wireless channel, channel width, security, some of these wireless parameters that may need tweaking, but start with the above and below link:

@Yashraj Hey. I'm sorry to know that you're facing the same issue. Many people are facing issues with C6. So, I replaced it with Archer A6 V3 (US). It is definitely better than the C6. If your product is currently within the return window, I suggest you to return it and purchase Archer A6 V3 (US) from Amazon India.

Dear, I am facing the same issue. Ping time also varies a lot and according the internet speed. ISP provider finds this as reason for speed varation of internet.

In case you have resolved the issue, please share the solution please.

@mks_005 

 

Have you tried this beta firmware that allows you to disable the Onemesh feature on the A6? If not yet, please give it a go, then confirm:
