Well that could be a good place to look. Unplug your modem & router for ten mins, make a cup of tea or something. Then plug in your modem, & wait for a few minutes. Plug your router back in & then see if you're getting constant web with your phone or other things. Do you have any other computers, if so, are they keeping connection on WiFi?
You could even reset the router. There must be a small hole on it for sticking a pen into it for reset, or a tiny button. Wait a few mins then get back on your internet, put
http://192.168.1.1 in your address bar. Since you reset the router, it will be "admin" & password will now be,
password. You should then be in the setup pages of your router. Have a look around the setting pages & there'll be one for setting up your router login. It'll be a page that asks you to select WEP, or WPA2 PSK security. Basically where it says "none" or "WEP" try to avoid these as you can be hacked. Go for the WPA-PSK [TKIP] + WPA2-PSK [AES].
You can change the routers name there as well (SSID broadcast).
Don't be shy of the router as you can reset it (it reverts to "admin" & "password" when you do that) but please, change the password to something better so that only people in your house can use it!
