Quoted from the site:

Hi sifu sifu, I just upgraded to the ax73 and done setup. Everything works fine except my BluguardP2P alarm device which is wired. In my tether app, it does not recognize the device. My cctv is also wired and works fine. Anybody has encountered? I tried swapping ports and restarting everything. Also upgraded to latest firmware after I got the router. Any ideas?

If your alarm system is configured to static IP previously, you’ll need to make sure your AX73 is operating on the same IP range.

Oh ya, if you use Unifi, the Unifi default VLAN profile disables LAN1 and LAN4 for normal devices.

I used LAN2 and LAN3, it didn’t come on the tether app. But can see in advanced as per pic below. How do I check the static ip? I doubt that is the case, it was plug and play. Any firewall steps I can disable?

I think most alarm vendor will set them on a fixed IP so it's hard to know it unless you know the previous configuration.

Do you remember what's the IP previously? It should be something like 192.168.xx.xx

Haha they just plugged it in. I am not sure…maybe can call them?

Anyways…is there a way to enable me to gain back access to LAN1 and LAN4? Since I don’t use hyyptv…seems to be a waste as I want to plug in my Apple TV and also smart tv or maybe an Xbox later down the road..

bought this AX90 on July. Almost never had a day that's smooth with this router.
At first it seems to be randomly disconnecting. Then I noticed the router was disconnecting every 60 minutes.
Their engineer even remote access my PC since 2 weeks ago, installed "debug firmware". Up till now, couldn't solve anything.
From the system log can see PADI & PADT thing keep appearing after disconnecting. It's always "resending". Not even sure what that means. And it takes like 5 minutes or more for PPPOE to connect.

TP-link engineer was also clinging on this matter and told me to ask ISP why is the PADI & PADT not getting respond.
I think this point maxis customer service had given up on me. They never replied any call to me.
Pretty sure the ONU is fine. Maxis & TM technician came twice to check and all. Said fibre signal was strong & good (-17dB)

this router feels real shitty to me. Almost not 1 day my blood pressure didn't spike from the disconnection.

Use M9 Deco in router mode with unifi 800mbps. Wireless speed becomes erratic, fluctuates sometimes even went down to under 100mbps. Had to disconnect and reconnect my PC from the network again to get faster speed.

Internal speed test with the TP-link app shows that I can only get maximum of around 500-600mbps downstream. upstream was not affected at 200mbps. Homecare was disabled and tried disable QoS and tried set them to maximum.

Today I revert back to AP mode. Internal speed test with the app, I can get full speed at 850mbps. Wireless speed is now more stable.

Something is definitely not right with the M9 Deco. Mine is v2 with latest firmware.

Try full reset and config again

Hi all,

I'm on a 300Mbps Unifi. Bought a AX73 to replace my old DLink Unifi router...however, after changing, it seems that my desktop wired connection speed is very slow, hitting only 1MBps download speed as compared to previously max speed. Even accessing the router admin page sometimes is slow. Meanwhile, on my mobile phone, the WiFi could reach max speed and has no issue

So, I retested with my old DLink router aain, and the wired connection has no issue reaching max speed though - what could be the problem here? Any setting related issue?

hi all,

I need some recommendation. I'm on times 100Mbps using Tplink Ax20 right now. I had Cat7 pulled to my study room. Please recommend me best budget one mesh enabled wifi router.

I will like to setup in my study room as secondary to boost signal to my master room.

I'm not considering switching to deco or getting higher end to replace as main router and existing ax20 as secondary as i'm only on 100Mbps line and not planning on upgrading. Mainly due to budget constraints 

Thanks!! 

LAN 1 and LAN 4 is reserved for IPTV and VOIP for the default TPLINK VLAN profile.

Make sure you use LAN2 or LAN3
