ok they just built a new apt building down the block and for whatever reason they have set up a public wifi am guessing for tennants. there was no password to get it and i had a perfect signal of 100 and link of 100 and my wifi worked pefect for about 3 months . now i can still get signal from them but cant connect ? on the list of wifis in my area it still comes up with no password needed ..when i connect it gives me ip subnet mask but the gateway comes up 0.0.0.0 ? now when i connect to another wifi it gives me gateway numbers ? i thought it was my pc so i tried laptop and wont let me connect any more to that awesome wifi of 100 signal......what am i doing wrong here ? could they have just pinpointed me and blocked me out ?
