May i ask. RT-N12HP default wireless setting will give those problems i listed in my first post? Or default wireless will work fine?

Maybe need to try only can know but if need to tweak, i will not accept the product.

It is not as advertised, easy and simple setup.

Not simple,

Report back here after you make those changes with your speedtest.
Would like to see if the changes works for yours. (It works for mine)

Need some help here: -

I bought RT-N12HP at Lazada, received today and after setup, i found that the speed test on PC connected using Lan cable is normal (Ping 15ms, Download 33mbps, Upload 10Mbps).

But to my surprise, WiFi connection tested on multiple android phone has below problem: -
1) Wireless connection unstable, some time disconnected.
2) Range is less then my Tp-Link Archer C1200 (Tm unit), around 50% less.
3) Speed test is inconsistent on multiple android phone. (see attached capture)
this must be a faulty unit unless some one can tell me simple solution to it.

I plan to return the unit to Lazada for full refund on Monday if no solution for it by then.

**Ps.. all setting default, only put in Pppoe setting and WiFi setting.

Answer is YES.

Enable Wireless Multicast Forwarding.  ---> https://routerguide.net/how-to-adjust-optim...-network-speed/
Disable Enable WMM ASPD ---> https://routerguide.net/wmm-apsd-on-or-off/
Disable Enhanced interference management  ---> Will force 40Mhz to 20Mhz + channel hopping around in congested environment.  ---> Probably this explain your wifi signal gone missing few moments then come back.
Set Tx Power adjustment to 200 mW  ---> default 80mw is too low. C1200 for instance transmit at 100mW

It is as advertised, easy and simple setup, no? 

setting done and apply and rebooted then test.

Hyppe working normally
tested using lan connected notebook, speed is normal. (see attached)
tested with android mobile phone, Ping, UL, DL - all not normal (see attached)

disappointing result. the router WiFi not working normally.

Try this - set no password for your wifi SSID and test again.

Many years ago had encountered an issue between wifi security settings and my old android phone. Something about the key settings or other.

If still same then maybe router is a lemon and needs to be sent to the shop.

tested.

Our condolence to you   We tried our best to help.

Hello all,
Recently I bought an Asus RT-AC1300UHP router (well not so recent, was already using about 3 months or so). I'm using the cable connection between router and my PC. One thing I noticed was that when I play games, the connection keeps on dropping out of sudden. This has never happened when I use my old TM stock router. Cable is fine, WiFi is also fine. Firmware is also up to date.
Problem : Internet connection out of sudden drop in middle of games.
Troubleshooting:
- State of cable - OK
- WiFi - OK
- Firmware - Up to date
Is there anything else that I could check to fix this issue?

Special thanks to JohnLai who take a lot of time and effort to help me.

now put back Archer C1200 TM unit back to work.

TQVM to all for helping,

i have done enough setup, twicking and testing, the result is disappointing and i have concluded the device is faulty.

i have call up Lazada and CS has ask me to return the product with original packing with all item and accessory to them for a full refund.

case closed.
