hi there, anybody got problem with their phone wifi conectivity ?

i bought my arc s ori dynamic set last week ~ 1st week use was fine till last 3 days ago my phone wifi kenot detect my house punya unify signal even though i stand in front of the router ~ my laptops and computers further distance all no problem receiving the wifi signal ~

i even tried fully reset my phone and reset my unify router n modem ~ problem is the phone can detect my neighbour's line which only have 1 or 2 bars but kenot detect my own home line while im standing in front of the router~

can anyone help ? i feel like throwing the phone on the floor ady ~ so frustrated with this phone ady 

after testing with those previous line tat i successfully can connect last time ~ it seems like now is those lines tat i connected b4 this all cannot be detected ~ walao weh

Wow this is nice, original casin/housin or not? How much? Really interested in midnite blue,white n grey/silver hehehe, thingkin to buy as spare if somehow the crack issue hit my arc.. Btw is it easy to change the casin/housin on our own?
