I've just moved into a 2 story timber house. The router (NBN supplied Huawei HG658 connected to HFC) is in one corner upstairs. Currently the connectivity is tolerable, but I haven't stress tested it yet, and assume it might be fairly ordinary. Most importantly, the pool area and the shed are some distance down the back, and I anticipate the wifi strength will be unacceptable for my needs. So, I'm thinking a mesh device might be the best long-term option. I've watched some videos to get a basic understanding of the concept, but seek recommendations on which devices are worth buying. Oh yeah, we use Google home devices throughout the house, if that means anything. I'm interested in maybe adding some smart devices such as lights down the track. Naturally I'd like to keep costs as low as possible, but I want quality hardware and software that's easy to set up and use. Any recommendations/suggestions?
