TP-Link is not taking the issue seriously. They are taking too long to fix this.

Bulgarian firmware already has the fix. Has someone flashed it and tested?

@Chezhian Have purchased Archer C5 from a dealer yesterday, but found that its disconnecting after some time automatically and again getting connected automatically. I am facing issues when connected on calls. Is there a solution to this problem.

Regards

@Kevin_Z do you have any update on this issue? Will there be a resolution provided?

@Kevin_Z I tried flashing the Bulgarian fixed firmware but the file wasn't accepted because the beta firmware's build number is higher.

Hope TP-Link can fix this issue. It has been too long. It''s unusable right now. My 5Ghz WiFi name itself disappears from the WiFi list. I have to reboot to connect to it again and it disconnects frequently.

Dear Sir,

Greetings from TP-Link !

We are extremely sorry for the inconvenience caused to you. we are receiving huge response from customers since lock down regulations are imposed.

We request you to refer attached firmware files of beta firmware and check,

To update firmware we request you to go to Advanced-> system tools->firmware upgrade and then browse downloaded file and click on upgrade.

First update 190820 firmware and then update 190904 firmware.

Note: 

1.Do NOT upgrade the firmware via wireless connection

2.Do NOT turn off the power or cut down the Ethernet cable during 

upgrade process.

Thank you, stay safe and take care of each other !

@Pankaj.jain Hey! Thanks for the reply.

My router has a later version of the firmware installed already.

Firmware Version:3.16.0 0.9.1 v6015.0 Build 200930 Rel.40632n_Beta

Hardware Version:Archer C5 v4 00000004

I think I won't be able to install the firmware that TP-Link sent to you because my version is higher. But I can try.

You can upload it on any file sharing service such as Google Drive or Zippyshare.

Thank you very much for sharing!

@Mashruk 

Have replaced the router. Vendor has issued me a new router with different model.
