Smart home device problems with THG3000 ... can't get ip address assigned ... AP isolation problem?

Hi...really struggled with some smart home devices after upgrading from Superfast 1 to 2 and getting the latest router (THG3000). Support were kind and helpful, but didn't get to the bottom of the problems. I was even given a fixed external ip address which apparently usually solves everything. Didn't for me and I ended up buying a different modem/router, which has solved all the problems (TP Link VR600 v3).

 

The devices I couldn't get to work properly were the Drayton Wiser Heat hub (worked fine with my previous vodafone HHG2500 router), a TP Link TC70 Camera and all Shelly devices. The problem seemed to be that they could not get an ip address assigned during setup. The Drayton device was strange, as it would always take an hour or more for an ip address to be assigned after a reboot. 

 

My Tuya and Meross devices worked fine though.

 

Having read some other online info, I think the problem may be due to the THG3000 having some problem with AP isolation. There's no way of turning it on or off, as you can with most modern routers, so can't say for sure.

 

I think this is a pretty big problem for people who are going down the smart home route, and took hours and hours of time and testing  to bottom out. Also cost me a new router. Hopefully, some sort of firmware upgrade will be able to sort it out in the future.

There are probably a number of different issues coming together here!

 

Getting a fixed IP only helps if there are remote servers that manage your devices and you can't use Dynamic DNS (DDNS).

 

The Shelly devices REALLY love to have a static IP addresses on the LAN!

 

As for AP isolation - it truly is a double-edged sword.  It's very easy to set up incorrectly and cause problems that are not instantly apparent, and in reality, it shouldn't be necessary for household broadband users to become network experts in order to set up, what are now everyday internet devices!

 

Glad you've got it all up and working now though!

I spoke to soon ... broadband speed has been down at 18Mbits/s ever since I installed the new router (48 hours) ... endless problems!

Warning for everyone  if you reboot or disconnect the Vodafone router or a substitute router too many times in a short period of time you will cause the broadband speed to drop as the D.L.M will think there is a fault on your phone line
