Router and smart wifi problems.

[#1]

Hi, hope this is in the right place ... if not please let me know..... I have a Hub One router and I am wondering if its starting to have issues. We have be adopting Amazon Alexa smart devices over the last few months. It has been a pain at time but has been working ... 🙂 

However, has any one had any issues as more and more devices are added? 

We seem to have bulbs / plus sockets loose connection after adding more devices.

Could it be an IP address problem? where newly  added  devices are taking address of devices that are switched off at the time ? If so does/did fixing addresses help?

Or an I barking up the wrong tree?

Thanks

One thing to do is to give the 5ghZ channel SSID a different name to the 2.4ghZ one; does that assist.
5ghZ is far less populated, but has less range than the lower frequency.

Thanks for that .... the 2 have different ssid's . After much playing about and assigning all wifi/smart devices a static address t I now think that the issue is on the alexa side . The devices now all work on there own apps just nor on alexa ...
