First: WI-Fi and Wireless are TWO DIFFERENT SERVICES..
Wi-Fi is generally park provided. WIRELESS is your cellular provider Now your phone (or other "Hot Spot" Device may convert Wireless (Cellular internet) to Wi-Fi and it may also be able to use Wi-Fi to make phone calls but this is under your control... to a point.
Wireless internet (No Service but a strong signal) YOu have SPRINT which advertises the IN NETWORK reliability is within 1% of Sprint. they do not advertise what IN NETWORK means.. (It means when you are connectred to a SPRINT tower) and they do not tell you that sprint has perhaps 10% (I am being kind) of the towers Verizon or AT&T or T-Mobile have .. Smallest "Nationwide" network in the country They mnerged with Nextel many years ago (over 10) and Nextel was nicknamed NO-Tel. Well. that covers it.
YOu may get a strong signal off a Tower due to a Roaming agreement but as a SPRINT customer. they may limit or even block internet access since they are NOT Sprint You phone should have an option to tell you what's happening or there is an app for Androids (Network Signal Info) that tells you who's towers you are using.. Most of the time *I have the freee version*
Wi-FI now is a whole different can of fish bate.
Many parks have simple Wi-Fi routers Like a common Linksys Home/Small office router. So here is the story of where I"m parked (Multiple routers.. today)(
Several years ago Id' head to the Family center (Internet hot spot) and hook up right about now.. I got connected no tribble. but as more and more folks came in suddenly they had a strong signal but no joy.
Turns out Linksys routers (They had basically taken it out of the box and plugged it in) only assign 50 IP Addresses
Think of a post office box store with 50 boxes. when they are all rented out "NO VACANCY" as it were.. Well I'd connect 'em by going Static IP and it worked (I wont bore you with that) ANd finally I though "I'll bet they never did something" sure enough they did not so I logged in and upped the box count to 100.. THere is a funny story after that.
Today that router is a an insustrial router which can do 500 or more boxes
So is the one I'm parked by but alas it's overloaded too
So you get a strong signal. but the router can not talk to you because either it does not have the bandwidth (Too many streaming videos) or it's out of addresses.
Home was where I park it. but alas the.
