We're talking about non-high-voltage wiring that you get from the "Cable" company. I recently acquired a service from Optimum at 200 Mips for internet only to replace DSL from Verizon. The phone is still from Verizon and TV is supplied via a broadcast antenna on the roof. No changes for those.
The wired Optimum cable works well. Blazingly fast in comparison to DSL but the WiFi component (laptop and Smart TV and another PC on another floor) is only comparable to DSL. Maybe slightly better for the other PC and the laptop. That wouldn't be a real problem but the Smart TV is. The real reason for the change is the Smart TV so that the wife can watch her garbage at Netflix. DSL is fine for (for example) posting to this NG.
Is it a problem with the supplied router? Maybe an inherent problem with WiFi? Maybe I can hard-wire it to the router? All these questions open up a bunch of others: What cable?; how long is permissible? CAT5e, CAT7? Advantages? Disadvantages? Which tool to add connector(s)? Where to buy? HD? Lowes?
I really need a book. Something like "DIY cable wiring/installation" but I don't see anything but maybe I'm looking for the wrong title or in the wrong place. Maybe there's a comprehensive websiite?
YouTube is NOT the answer. People who post there are incompetent in both the video production and content. Amateur p*rn is better and that's really scraping the bottom of the barrel.
In terms of books on DIY I think the old fashioned Goodheart-Wilcox series is excellent but out-of-date now. I think they were texts for "shop" in high school.
Any suggestions as to good information sources?
