So I'm leaning towards buying Powerline adapters. It seems pretty easy to set up, and would be relatively cheap to buy a set to start with, and expand over time. I do have a couple of questions though:
1. How many adapters would I need for my setup? I'm envisaging having an ISP-supplied router connected to the ONT, which will be routing data for two to three computers in different rooms. Would I have one adpater connected to the router, and then one adpater for each of the PCs (three to four adpaters in total)? Or would it be a one-to-one arrangement, with multiple adapters connected to the router for each PC being serviced (four to six adpaters)?
2. Will 200mbps be fine for UFB, or would 500mbps be better? I'm thinking of my experience with wireless N's "300mbps" speed which is much lower in practice. I understand that the condition of the wiring is a factor in overall speeds so presumably if the wiring limits actual speeds to about 100mbps, I'm presuming that a 500mbps adapter isn't going to magic up extra speed.
3. I've been looking at a TP-Link set of adapters. Any recommendations on brand? Are the brands compatible if they use the same standard, or not really?
4. By my estimates, the cheapest I could set up a powerline network (using 2 x TP-Link 200mbps kits (2 adapters in each kit) is about $150. Is it fair to say that the other options - a professional ethernet installation or laying the ethernet cables under the hourse myself - are going to be significantly more expensive than $150?
5. Does any of this make sense? :)
