No Internet when going from one Router to another Access Point

[pepemosca]

Hello,
I'd tried to look for a solution to my problem... But I'm not able to find it. So, first, sorry if this topic was previously discussed.

My setup:

• ASUS Router RT-AC87U
  • Running Merlin 380.59_0
  • Set up as Wireless router mode (Default)
  • Wired to the fiber cable from my ISP
  • Screen capture from: http://192.168.1.1/Advanced_DHCP_Content.asp

• ASUS Router RT-AC66R
  • Running Merlin 380.59_0
  • Set up as Access Point(AP) mode
  • Wired to the AC87U via TP-LINK TL-PA8030P KIT
  • Screen capture from: http://192.168.1.123/Advanced_LAN_Content.asp

• TP-LINK TL-PA8030P KIT
  
  • I connect the AC87U to the AC66R via this PLC
  • Connected via the home power line. I live in a flat
  • I get speeds around 170/170 Mbps at the second router AC66R
  • In the main router AC87R, I have 300/300 Mbps

The SSIDs from the two routers are the same.
In the 2.4 GHz the name is "AA (2.4)" in both AC87U and AC66R.
Also, the 5 GHz the name is "AA (5)" in both AC87U and AC66R.

My problem is that if I walk from one room to the other... I get no Internet.
I have to turn off and on the WiFi to get back service. It's just click off and on to get back the service.

I had notice, in the main router AC87U, I get this message all the time:

Any ideas? Thank you for your help.

There may be too much overlap between your router and AP. Devices won't switch APs unless signal level drops below a certain value.

Check to see if your device settings include a roaming setting.

Try REDUCING the transmit power of one or both of the routers.

Thank you for your reply... but what do you mean with the previous comment?

I suspect thiggins is correct, too much overlap.

There are a few things that I would change with the setup you've got showing there.
1. Enable the Manual Assignment on the AC87U for the DHCP.
2. Add your Access Point into the list and set it up as 192.168.1.2
3. While you're at it manually assign your iPhone and MBP addresses as well.
4. Go to your AP and then set it to get a DHCP address.
Reboot the AP and you'll now connect to it over 192.168.1.2

If you're like me and have too many neighbours in the 2.4GHz range you can disable the 2.4GHz radio on the AP (under Wireless Professional) and just stick to the 5GHz. I use the 5GHz radio for most of my devices (I've got two that only have 2.4GHz radios) and the 2.4GHz is close enough for the other two to connect reliably that I leave on the 2.4GHz on the AC87U.

Forget the 2.4GHz SSID from all your devices that have 5GHz radios.

I use Channel 36 on the 87U and 44 on the AP, you can also configure the Roaming Assistant under the Wireless Professional tab, I'm typically closer to the AP so I've set the 87U to drop my clients if their signal is less than -70 and on the AP to drop them if they're lower than -75.

The above are just suggestions. If you have a program running on your MBP that can show what WiFi channels your neighbours are using you can adjust the channel assignments accordingly. I use WiFi Explorer.

See the screenshot. Not all adapters have this setting.

Thank you all for your replies.
I will test using the Roaming features on the wifi cards and on the router at http://192.168.1.1/Advanced_WAdvanced_Content.asp

Also I will play with the AC87U and AC66R DHCP configurations.

I will post back. Thanks!
