Hi,

I assume you are referring to electricity blackouts that affect your whole home. (i.e. everything turns off at once)

Have you already tested what happens if you only power off one router at a time?

I mean like, power off the ISP's router, wait a minute or so, power it back on and see if the A6 successfully re-establishes all connections or not.

Likewise, power off the A6, wait a minute or so, power it back on and see if the A6 successfully re-establishes all connections or not.

I wonder if it's maybe the ISP's router that we need to take a look at.

Hi,

Yup there is a problem with the both the isp router and my tp link router. i switched off both the routers for about 2 minutes and both refused to form a connection after either one of them became offline. my tp link router gets changed and it refuses to connect.

Thanks for your response do you think dynamic ip is the problem because the isp provider has specifically told me to not change any setting in the main router.

Of course it would make sense to document the present settings of the ISP router before you change any of them.

Could you please post the ISP router's settings for its internal LAN network, the DHCP server and the Wi-Fi ? (bar anything you deem to be personal information)

My isp onu router default connection type is pppoe so should i ask him the username and password for bridging?

  @Killwish 

If the onu router connects you to a fiber optics line via PPPoE and you want to build a wireless bridge (WDS) between the onu router and the Archer A6, then you will have to leave the general arrangement of the two routers as it is.

Unless you accidently delete the PPPoE username and password entries, you don't need to know them at this point. But of course it's always better to have that information at hand, in case it is ever needed.

I'm having the same issue - Archer A6 V3 - setup with WDS bridging mode on existing wifi connection from ISP router.

When the local ISP router (which provides the wifi/internet connection) reboots for whatever reason (power cut, firmware update, manual reboot), the Archer A6 loses the WDS bridge connection and won't reconnect.

The only way to rectify this I have found, is to manually refresh the WDS bridging settings via the web interface:- Find and select the same wifi network again, save the configuration again with the same settings, which restores the WDS bridge and internet access.

There is another wifi extender at the other end of the house which doesn't experience this issue, and every other device in the house reconnects to the ISP router wifi without issue, which comfortably narrows the issue down to the Archer A6, at least with WDS mode.

Very frustrating.

To explain further, I set the Archer's IP address to 192.168.20.254, so when this issue occurs I'm easily able to access the web UI via ethernet to refresh the WDS bridge settings. Before changing the IP, I was still seeing these issues.

it is a ZTE Gpon ont router Model Number is ZXHNF670L

That is the problem it is getting on my nerves also. The router only works as a access point but refuses to work as a repeater
