TP-Link Archer C7 (hardware version v2) is the most unstable-working router I ever had. It randomly stopped working at least once in two days.
Sometimes I had to restart it three times a day but Internet was constantly dropping (even when connected via Ethernet) and Wi-Fi kept disconnecting all the time. Now and then 5 GHz network dropped until I power cycled the device.
In summer 2017 I tried to upgrade its firmware to the latest version but nothing helped and I continued to reset the router on freeze.
But here is a solution that finally helped me stop all those hangings and unstable work of Archer
C7. Besides, we’ve got a workaround to fix such unreliable work of your router if the solution doesn’t suit you for some reason.
How The Unreliable Work Of Archer C7 Looks Like
The issue with this TP-Link router looks like the following. Windows PCs connected via Ethernet show “No Internet“.
Android devices may see Archer’s Wi-Fi network but won’t connect, telling that your wireless network is “Disabled”:
It goes without question that there is no Internet and LAN at all.
The Solution (Worked In Our Case)
Update the firmware to the latest US version. If you are not from US, you may not have one for your country. So you have nothing to do except flash US firmware. Your router will warn you about incorrect region but don’t be afraid to flash it.
- Go to the Archer C7 web page on TP-Link support website for United States. https://www.tp-link.com/us/download/Archer-C7_V2.html#Firmware
- Download the firmware Archer C7(US)_V2_170525 with published date: 2017-07-24.
- Log in to your router’s config (192.168.0.1 by default if you haven’t changed its IP-address).
- Head to System Tools > Firmware Upgrade.
- Click Choose file:
- Browse the firmware file and click Open:
- Click Upgrade:
- Wait until device reboots.
Once we installed the US firmware our Archer C7 stopped dropping 5 GHz Wi-Fi and losing the Internet connection. Now it is working like a charm during 2 months without reset.
The Workaround: Disable Hardware NAT to Fix Archer C7 Hangings
Please, let us know if this helped you stop your TP-Link Archer router hanging.
Thus, we must admit that Archer C7 is nevertheless a great router (again) with stable Wi-Fi and gigabit LAN and WAN ports. We hope that TP-Link won’t make such lapses with firmware in future. We’d like to remember you that this story was about Archer C7 with hardware version V2.
