I bought a Tablet Samsung S2 in the USA,and it worked fine about wifi in 3 different places(2 hotels and even a train).
But when I went back to my hometown in Europe the tablet cannot find my wifi signal at my own home(it finds many other signals,but not mine).
I pushed the WPS button in the router, the MAC filter si disabled,etc...buy nothing seems to work.
What can be the reason?
Should I browse anything in the developer options?
