please any help, thanks

What happens if you try to long-press the name of your WiFi and tap 'remove', search again and type in the password?

i did, still the same 😕

i also noticed that i only cannot connect with my home router, but with other Wi-Fi's it works! my home router works too because there's a laptop & other phones (like xperia arc) are connected and there's no problems at all

Well now it sounds really strange. And it all worked fine until 4 days ago? Did you update anything in phone or on the router? Maybe changed some settings?

Make sure the router is broadcasting on a channel below 11, since everything above tends to cause issues.

i know right it's strange! and i didn't make any updates not on the phone nor the router, I'll try tomake the brodcast on the router

yesterday i've got another ion and it has the same problem, I changed the channel brodcasting from 10 to 11, then both of the phones worked good, 10 minutes later my old Ion got back to the same problem 😕 even on channel 11.

now what's the problem?!
