On my android 4.2. tablet, in the last two days, WiFi shows only 2 bars and with that I can't open any website.
On my laptop it went from 5 to 4 bars. So it looks like a signal/router issue, not the receiving devices.
I'm placed next to the D-Link Router, only a wall is splitting us as it was before.
I tried WiFi Analyzer and transferred signal to a free channel, as far away from my neighbors, but still the same.
I used also WiFi signal Booster from Google Play on Android device, still no luck.
What can I do now? Please advise. Can dust mess up router, should I clean it with air spray, I don't know - I'm wild guessing.
