I have a wireless router at home for internet access for laptops & phones. But the signal does not reach to the farthest rooms. So if you are surfing on a smart phone, it uses the phone link instead and sucks up data usage.
The current router is better than the previous, but still not good enough. Is there something like a repeater or booster I can use to push the signal further ? Or do I need a stronger signal from the router ?
Are routers rated by signal strength in some way ?
