Hello,
After recently upgrading the firmware version to the latest one my router keeps losing internet connection to the 2.4 network and all my smart devices have to be manually reconnected every few hours. This does not seem to affect the 5G network or the LAN devices, they work perfectly fine. I am in no way an expert so I am going to try my best to explain the behavior I have observed so far:
1.The 2.4 network keeps broadcasting but device are unable to connect to the internet ( like unplugging the LAN cable from your ISP from the back of the router but leaving the router on )
2. Rebooting the smart devices does not fix the issue as they still cannot connect to the network
3. Rebooting the router sometimes works, sometimes it does not
4. I use a Fiber-optic connection and the router is connected to another router provided by the ISP. I am not sure if this could cause the problem as the 5G connection and the LAN works perfectly fine but thought I should mention
So after searching the forums and trying various fixes here's what I have tried until now:
1. Rebooting the Router
2. Backup & factory resetting the router
3. Using a WiFi analyzer and setting the channels to the clear ones, also setting the transmitting power to max and channel bandwidth to max. (This did not work so I have reverted to AUTO )
4. Upgrading my firmware to a beta version 1.3.6 Build 20200819 rel.50735(4555)
5. Disabled Smart connect
Do you guys have any idea if this is related to the firmware version or is a hardware version? Also if it is firmware version do you have a previous build (2020) I could restore to as I am unable to find a list with previous firmware versions on TPLink's website
Also do you have any more tips I could try as I am working from home and my work Optiplex is using the 2.4 Connection so getting disconnected every few hours is becoming extremely infuriating and it is compromising my work.
PS: I have the EU V2. hardware version
Hello,
The 2.4G network is visible and my devices usually give the " Unable to connect to the network" error. Once my iPhone was unable to connect and the error mentioned to check the DHCP setting but I cannot recall the exact error message.
I have two light strips, two light bulbs, and two Echo Dots also some smart panels from Nanoleaf. So that comes to about 10-12 devices.
Edit: The devices disconnect at least once every 24 Hrs but it's pretty random. They do remain connected for some time after rebooting but not more than 6-8 hours
Here are some snips:
Losing WAN connection regularily (5-20x a day I run into it, I suppose it happens more often).
When connected to ISP modem directly no disconnects happen.
Hardware: Archer C6(EU) v2.0
Firmware Version: Latest official: 1.3.6 Build 20200902 rel.65591(4555)
My PC is connected via ethernet cable, as well as a HP printer and two Raspberry Pi's.
One TP-Link Tapo C100, an iPhone, an iPad and two Sonos Wireless Speakers are connected via 2.4 GHz and 5 GHz Wifi.
No Guest-Wifi, no QoS, no Parental Controls, SPI firewall active (default setting), NAT forwarding: 4 virtual server rules active, OpenVPN VPN-Server active
I already did a factory reset, nothing changed.
I see that for the US-Version of the router there is an update available (Archer C6(US)_V2_210226 - https://www.tp-link.com/us/support/download/archer-c6/#Firmware ) that has a description like "Fixed the bug that unstable WAN connection under certain circumstances".
Can you please, please, also fix that issue for the EU-version?
This is becoming very annoying for me and happening more and more often.
Attached you will find a ping result file. I "masked" my IP-Addresses for security reasons.
You will still see the behaviour.
Also attached you find a screenshot of my router's webpage when the error occurs.
I ran a second computer straight from the ISP modem from its second eth-port. There I had _no_ lost connection over the whole time period when I was monitoring on this second computer.
In the near future I want to expand with a RE300 mesh-repeater that was recommended to my by your support. I already bought it. So deactivating mesh is no solution to me (in case this is the issue). Since the US-Version has an update it should also be possible for the EU-Version, right?
I don't want to put OpenWRT firmware on it and also not throw it in the bin, since I like the router very much as it is except this bug.
Thank you for your help.
