    Is RT-AX3000 lot better than RT-AC68U?

    Can confirm. I've had a RT-AX3000 and the first firmware that actually worked "properly" (except for the dnsmasq infinite loop w/DNSSEC https://www.snbforums.com/threads/rt-ax3000-dhcp-and-dns-randomly-stop-working.77261/) is 386.4_0. All the previous firmwares had instability, reboots...

    RT-AX3000 Dual-wan suggestions

    Two suggestions about dual-wan (failover mode): 1) If you unplug the primary wan cable, it fails over properly. However, going into the web admin page and disabling the primary WAN connection in the network map screen DOES NOT trigger a failover. The system should immediately failover if the...

    RT-AX3000: DHCP and DNS randomly stop working

    After the factory reset and leaving DNSSEC disabled, I have not had the issue reoccur. I will update this post if it does, but I'm now running dual wan and I've had no issues. Failover works as expected and the router works great. No DHCP or DNS issues now.

    That saved me SO much time. Thank you!

    RT-AX3000: DHCP and DNS randomly stop working

    DNSSEC was enabled. I will ensure I disable it. Thank you @dave14305

    RT-AX3000 crashing every few days in bcmsw_rx (Tried hw/sw reset/rebuilds and even new replacement router)

    FYI: After upgrading, I've been having this issue. I don't know what's causing it, and it could be that I configured dual wan, or it could be a problem with the firmware.

    RT-AX3000: DHCP and DNS randomly stop working

    I've got an ASUS RT-AX3000. I just updated to the latest firmware (386.4_0) and it seemed stable for a few days. I then enabled dual-wan in failover mode and that worked great. I tested pulling the network connection and it would failover and fail back as expected. I also disabled 2.4 GHZ...

    RT-AX3000 crashing every few days in bcmsw_rx (Tried hw/sw reset/rebuilds and even new replacement router)

    No more unexpected crashes or events. Pretty confident things are good with the 386.4 firmware. Thank you Merlin for all your great work! Now configuring dual lan and installing AP's, so I'll be disabling some of the wireless features. This may invalidate my testing or possibly discover new...

    nf_conntrack: expectation table full and other log oddities

    I put the script in place on my RT-AX3000, but restarting the conntrack service (service restart_conntrack) always resets /proc/sys/net/netfilter/nf_conntrack_expect_max to 150. So at least on RT-AX3000 386.4_0, I expect this script does nothing. I am also getting the errors in dmesg. That...

    RT-AX3000 crashing every few days in bcmsw_rx (Tried hw/sw reset/rebuilds and even new replacement router)

    conn_diag memory leak is gone. Still using 13MB after a week. Crashes might also be fixed... 1 week later and no crashes. Also no random wifi interrupts on 5ghz, which happened occasionally (once an hour for ~5 seconds) before. Will need more time to test, but this is looking like it might...

    RT-AX3000 crashing every few days in bcmsw_rx (Tried hw/sw reset/rebuilds and even new replacement router)

    8 hours later, conn_diag is still using 13MB RAM. So the memory leak present in 384.19_0 is fixed in 386.4_0 (and likely some earlier firmware). I have not had a crash, but 8 hours is not enough time to confirm stability. I also had some errors in dmesg: "nf_conntrack: expectation table...

    RT-AX3000 crashing every few days in bcmsw_rx (Tried hw/sw reset/rebuilds and even new replacement router)

    I have upgraded this morning to 386.4_0 and am testing. On 384.19_0, memory usage of conn_diag had grown by 6MB in the last 16 hours, confirming that there was a memory leak in that old firmware, at least with my hardware. After upgrade, conn_diag is using 13MB RAM total.

    RT-AX3000 crashing every few days in bcmsw_rx (Tried hw/sw reset/rebuilds and even new replacement router)

    @seanwo I will upgrade and let you know. That said, I've had a single crash on the 384 in the same bcmsw_rx module, after the router ran out of memory. People having this issue should check top to see if they have much free memory and hit M after running top to see if conn_diag is using a lot...

    RT-AX3000 random crashing pointing to bcm modules

    FYI - You're not the only one having issues. Looks like a firmware issue with at least some configurations in 386.2_6+ https://www.snbforums.com/threads/rt-ax3000-crashing-every-few-days-in-bcmsw_rx-tried-hw-sw-reset-rebuilds-and-even-new-replacement-router.74503/

    RT-AX3000 crashing every few days in bcmsw_rx (Tried hw/sw reset/rebuilds and even new replacement router)

    Seeing the same crashes here on my RT-AX3000 w/386.3_2. Happens once every 1-3 days. Don't use guest network at all. Interestingly, I see a TON of "wl_cfg80211_change_station : WLC_SCB_AUTHORIZE sta_flags_mask not set " errors right before the kernel panic. Not sure that this happens every...
