so a repeater or booster of the signal can't be done? i thought there were devices that take in a signal, boost it, and send it back out. not so? sounds good in theory, but i'm a newbie.
i actually bought a pc wifi adapter and the signal is being picked up indoors. it's strength seems to vary. i guess that's the nature of hotspots? does it depend on how many people are using it? odd the speed is said to be 100Mbps, yet i get between 1-3 Mbps. why would the speed be listed that high when it's not the case? i also get 2 out of 5 bars. not sure how relates to speed. any insights?
What do you mean by hotspot? I use my gateway's wifi, not its hotspot.
There are ways to increase the range of a gateway's wifi but a gateway's hotspot can't be boosted.
Try googleing powerline wifi.
at home i use the comcast router to get my wifi, no sweat. at my other location, i don't have a comcast router. but there is a hotspot nearby (about 150 yards away, unless in an office in my building someone has a comcast router), and that signal fluctuates. according to windows 10, i always get 2 of 5 bars on signal quality, i guess considered a fair signal (also according to my tablet).
sometimes i do get 8Mbps, which is plenty. other times, almost 0.
would a large antenna help, maybe boosting signal quality? or is this an issue of the hotspot, maybe when busy, just puts out less bandwidth to my desk?
It is entirely what the hotspot can provide. Outside a business that has xfinitywifi, it is very difficult to get a strong signal.
And the business has no way to strengthen the signal. (I think)
I might even suspect a business wouldn't want someone outside the business being able to use their wifi bandwidth.
