Just one more add, as I read in some post that the guest wifi only works with 2 different networks if we use the deco m5 as router.

I'm using it as router with the other 3 (4 total m5) connected by cable and wifi and is not working.

So bottom line, the guest only connects on the principal m5 and even there the network is the same as the home range addresses, so the only thing you do is give a different password to access to all my network...

Please solve thing asap. It's a huge security issue.

Probably no one can use guest wifi until you solve this as we can't allow stragers to access all our network.

Hello @TP-Link_Deco,

Thanks for your reply.

That's correct, however they can access the router itself, something it could be avoid with a simple ip or link rule which avoid the guest network (if different) to access remotely to it (https://tplinkdeco.net).

If on the same network, rules will not be possible to apply...

Just one more add if you can help or pass through the information:

It's only possible to access to the guest Wi-Fi if you do it on the primary DECO M5. If you try it on a second, third and so on, you get no assign IP address.

@TP-Link_Deco, you are correct... It's a mesh network, but:

If you try to access the guest network, when you're in a point away from the principal deco, so you get another deco on the network, the guest access won't let you to get an ip address.

With the regular network it's working fine.

Just put two deco's away from each other (seeing itself :) ) and try connect to the guest WiFi near the principal one. It will connect and get the ip address. All will work smoothly.

Now go next to the other one and try to access to the guest WiFi. You will see that will have a huge delay to access to it and when finally do never capture an ip address.

If you do the same test with the regular WiFi it will work ok.
