I own the BE800 which is also directly connected to the fiber network of my ISP (the dutch company; Delta), I suffer exact the same problem.. During the renewal, approx. every 15min, the connection also drops (shortly) in my whole network with the result that some of my connected devices sometimes raise an error. I guess because we suffer the same problem(s) this isn't related to just your BE400 but the entire BExxx line-up...

 

Any help would be appreciated!

 

Thanks

Thank you for your reply. Yes, I also have my internet from a Dutch company (Odido), and I saw this problem in other threads on the TP-Link community. However, I wanted to mention my BE400 to get the right firmware updates from a specialist (if that was the solution).   

 

 

This is a very weird problem with TP-Link routers. I mean, they're good and powerful routers, but to have a problem like this? Anyway, let's hope it gets solved.

Hello, thank you very much for your reply.

 

Yes, I checked the DHCP settings on the router that I got from my ISP and found that the lease time was set to 1 day. I already changed the lease time to 1 day on my BE400, but the lease renewal message kept popping up in the system log, and I got internet drops every 15 minutes, as I said in the beginning. 

 

Anyway, that has nothing to do with the DHCP on my LAN. The DHCP renewal messages are related to the WAN or the interface IP address that my router is trying to get from my ISP. Here is where the problem occurs.

 

What I found in the router of my ISP is that the WAN connection type was automatically set to IPoE, and I cannot find that option during the setup of my BE400. I could only select Dynamic IP instead. And yes i got different routers before but i haven't faced this problem before, only on my tplink router.

 

 

 

Here is the complete topology of my network:

•  Nokia ONT XS-010X-Q - Fiber Modem directly connected to my BE400 through Cat 8 ethernet port.
• Smart TV 
• 5 Smart led lamps
• 1 IP Camera 
• 4 Smartphones and 1 PC
• 1 PS5 Device 

 

All devices above are wirelessly connected to my BE400; just the ONT fiber modem is connected through an ethernet cable.

------------------------------------------------------

 

 

As I mentioned in my previous message, I connected the router that I got from my ISP directly to the Fiber ONT modem.

I checked the WAN connection inside that router and then plugged my BE400 into the ISP router as an access point router. I kept the LAN DHCP on my ISP router, so I got internet connection this way.

 

But, when I went back to my BE400, I saw in the system log that my BE400 was asking my ISP router for a new IP every few minutes, too! This was even after I set the BE400 to Static IP and configured my ISP router to do an IP reservation (or permanent IP address) for the BE400.

After this experiment, I think that there is a bug in the firmware of my BE400. Maybe I did something wrong, but my BE400 keeps asking for an IP renewal every 15 minutes or sometimes even sooner.

 

Router that i got from my ISP is:  Zyexl T-56

 

 

Hope this information is clear and helps.

Thanks

Hello, Thank you for your help.

 

Yes, I received a message on my email and I replied to the mail with the forum ID and the necessary files.

 

 

I also did what you mentioned in this way: Nokia ONT → Zyxel T-56 (Router Mode) → BE400 (AP Mode)

 

The result was that the BE400 kept asking for a WAN IP as I said in my previous message, and the 802.1Q VLAN ID is set on my BE400 to 300 (as it was required by my ISP).

 

 

Thanks again, 

Best regards
