We now have two sets of users in our house. My family on one floor and tenants in a flat in the basement. We have one Modem/Router (a Vodafone Broadband Complete (Huawei)). Upstairs we have high volumn clients (streaming video) connected via ethernet and a few lower throughputs connected via WiFi (Airplay music straeming, occasional iPhone/iPod browsing). Our tenants are using their mobiles as their only phones and we are letting them connect to the internet through our Wifi (for a fee). Since they are on the Wifi and most of our stuff is ethernet, there doesn't appear to be a clash there. Also, I'll probably upgrade to a dual band router with guest network, so I can keep them ringfenced in the 2.4 GHz guest network and use the 5.0 GHz for any higher volume Wifi we might need. Also, the guest network will give more security. I'm confident the arrangement above will mnean we have no bandwidth clashes on our network, even when we are both streaming video. However, it seems that there is an obvious bottleneck at the modem, if we were both streaming in from the internet at the same time. So (finally) my question. Will the bottleneck be the modem? If so, what can be done to improve that? i.e. could we have two modems and one (or even two) routers? But would that just shift the bottleneck from the modem to the line between the modem(s) and the street? Note, the tenants have a phone line, but it is dead. I think it comes into the main house and then is split off, but while our line is live, their's is dead.
