Hello,
For the past few years, I've been happily using OpenWRT on my TL-WDR4300 to bridge Ethernet and Wi-Fi, and it's been working great.
A few weeks ago, I started having an intermittent Ethernet connectivity issue (probably not OpenWRT or TL-WDR4300's fault); still, I upgraded my TL-WDR4300's firmware to 18.06.1 in hopes of resolving it.
After the upgrade, Wi-Fi doesn't seem to work at all. The SSID is broadcast and devices connect successfully, and actually get an IP, but nothing else works (can't ping neither the router nor gateway). DHCP definitely works, which leads me to believe there is some routing issue causing broadcast packets to get through, but not much else.

Any ideas?
Bump.
I've tried a factory reset, then followed https://openwrt.org/docs/guide-user/network/wifi/dumbap .
Looks like the Wi-Fi does work, just extremely poorly.
i.e., here's what mtr looks like with sitting 1 foot from the router:

The 5GHz one looks better, but still quite spotty:

This looks like a pretty bad regression. What could cause this? Is there a workaround?
maybe hardware defect?
i'm using the sam router:

So far for the past 6 months it's working great.
I'm restarting the router everyday with cronjob at 4.30AM
Hi,
I have upgraded my WDR4300 as well to 18.06.1, I'm using it as a dumb AP with 2 SSIDs (one in clear, one WPA2), and it does work but I do see issues as well, especially after running it for a few days. The symptom is the following :
Router is pingable and can be logged into
Router can ping ip addresses inside the wired network,
Router can't ping devices hooked up to its wifi, and the opposite is true as well - devices can't use the wifi anymore to connect to the network.
only a reboot fixes the issue.
i have also implemented a cron restart once a week, but at this point I think one every day would probably be safer.
This is really problematic, i'm considering buying something new if this can't be fixed.
