Hi AsusMy, I really can't stand the Asus N12u-B1 modem router ady. There's one thing that I don't understand. It's so sucky that whenever me and bro playing the same online game, one of us will lag off for sure and disconnect. Sometimes, the wifi can't be detectable. Any idea on what's happening? This is my warranty unit. The one before also got the same exact problem. Also, I'm not the only one who's facing the problem, my friend facing it as well. Thank you

Hey thanks for the reply. Using the latest one. 1.0.4.1

I'm using this model. https://www.asus.com/Networking/DSLN12U_B1/

Not the one that u've posted

It's okay =). Yeah I did. I even got a RMA unit that comes with the latest firmware but the problem still occurs most of the time.

As mentioned. My pc is on LAN whereby my bro's is on Wireless. LAN seems to be fine. Only the Wireless causing the issue.

Hi guys, I've gotten a really weird issue. I have 2 AIMESH node tie to a main router. They are all AX55 and running on the same subnet and gateway, but I just could not ping some of the wireless devices (especially printers) from devices that are connected via Ethernet.

Update: Switching off smart-connect and splitting the Wireless SSID for 2.4/5ghz still doesn't work. My local machine can ping other wireless machines, but not wireless printers.

Hi Asus MY,

Are you able to support my case on the earlier reply? Thank you so much

1) The firmaware is running on latest Version 3.0.0.4.386.41700 (Have not tried the one that released just yesterday)
2) All PC / Devices that are wireless connected are able to use the printer. My only LAN connected PC unable to ping nor use the printer.
3) The printer is connected to the main router.
5) Router able to ping printer with good latency. The main router is basically sitting in the same room with the printer.

Note: I have two wireless printers in different rooms. Oddly, My LAN connected PC could not ping neither. It's happening only on wireless printers as I have scaled down that it can pings to every wireless connected PCs.

Test 2: Lan to Lan devices that are connected to the main router is not ping-able as well.

Test 3: Router itself could not ping to LAN connected devices

I can conclude that this is a firmware issue. I have reset the router to factory setting after upgraded the latest firmware without any node attached. Yet, the ping from LAN connected PC to wireless printers just doesn't work even without AIMESH configured.

Appreciate that ASUS Malaysia can fix this ASAP. I'm running on Maxis Fibre. I have tried connecting to both LAN port 1 & 4 with two different devices. Both unable to ping each other as well, nor the router can ping both of them.

Unfortunately, it has nothing to do with the hardware itself but software. I purchased 3 units of AX-55. All 3 are having the same issue after spending sometime resetting and swapping.

Funny thing is that they are all sitting under the same subnet and a simple network topology without any switches involved, it just couldn't get ping to any of the wireless printers nor pinging between Lan-to-Lan devices. Wireless-to-wireless are working perfectly.

Hi Asus team,

Thanks for the simulating the test.

Are you on Maxis as well? If not, I'm suspecting that it has something to do with the ISP profiling that has messed up things up. Yes, I'm using Maxis-Fibre profile without "Special" as the modem provided is from TM.

I do not have IPTV. Thus, LAN port 3 is free. The test 2 & 3 were simulated with port 1 & 4.

Huh? It can't be. I have tested not on 1 unit, but 3 units. 3 units are facing the same issue.

My Mac is running on GBe LAN port and it's still the same. There's no VPN connection involved. Swapping it back to my AC1300UHP for the time being.

Solution:
After hours of testing, finally found the solution. It was the maxis ISP profile that messed things up!

Using the manual setting as per below has resolved the problem.
