My TP-Link Archer A7 v5 running OpenWrt 22.03.3 intermittently stops working until I manually reboot it. This happens anywhere from once every few days to a few times a day. The symptoms are that the internet will stop working over Wi-Fi from my laptop, but my Wi-Fi connection will still be stable. When this happens, I can still ping the router at 192.168.1.1 but I can no longer ping Google DNS at 8.8.8.8 or another device on my network at 192.168.1.191. If I connect my laptop to the network with an ethernet cable, I have access to the WAN and LAN again. Once I remove the ethernet cable and go back to Wi-Fi, I lose access to the WAN and LAN. Typically I solve this by opening up the OpenWRT control panel (over W-Fi) and go to System > Reboot, everything starts working again. It's almost like the bridge between the Wi-Fi and the LAN/WAN crashes until I reboot. Any tips or ideas?

I am assuming these config files are static, but in case it matters: I printed them out while everything was working correctly.

Your configuration appears to be pretty straightfoward, generally not far from the default state.
Have you installed any packages?
Does the problem affect all devices on wifi, or just your laptop?
You could look into the logs and see if there's some error when you lose network connection on wifi...
Your config seems ok. If there's no error, I'll recommend just flashing with the latest build again and start from scratch with default configs.
I also have A7 v5 and as a rule of thumb, I have set it to restart every morning at 6am automatically...this fixes almost any type of issue if there is any.
Here's my restart cronjob,
01 06 * * * sleep 70 && touch /etc/banner && reboot
Thanks!
- As far as I remember, this is exactly the default configuration.
- I did try to flash with the latest build once, and I'll do it again with the next release.
- This error appears on other wireless devices besides my laptop, including my phone.
I have noticed that I can trigger this consistently now. If I only use wifi, it will work indefinitely. When I plug into the wired connection, and then disconnect, the wifi will stop working within a few minutes.
I will try to add the reboot cronjob and see if that helps.
The reboot does not seem to help. This happens more frequently and consistently than every 24 hours. If I find a solution I will post it. I’m the meantime any other help is appreciated.
In the meantime, is there some way to add a hook so that the router automatically reboots whenever a client disconnects from the wired network?
Maybe not quite what you’re looking for but you can try luci-app-watchcat. It can restart wifi or reboot router if a connection goes down (ie cant ping)
After testing 22.03.5 and having the same issues, I finally went back to the factory firmware. This fixed the issue.
I also learned that my ISP recently upgraded me to 1Gbps download, but OpenWrt had been limiting me to around 500Mbps. The factory firmware provides the full 1Gbps download.
The rabbit hole goes much deeper. It turns out the router still had the same behavior sometimes even without OpenWRT, I just hadn't triggered it yet. So I upgraded to a new router: the AX3000. And now I am seeing the same behavior with the AX3000 intermittently. Which makes me wonder if this is a general TP-Link problem, or if it is something even weirder involving my cable modem.
