Hi, The wireless signal is given as dBm units. That's an absolute measure of the signal strength. 0 dBm represents one mW (milliWatt). As this is on a logarithmic scale, -3dBm represents half of that power: 0.5 mW or 500 micro Watts. 3 dBm would reprensent a double of that power: 2 mW typically a wireless receiver operates between -10 and -100dBm which means a power between 100 microWatts and 100 picoWatts. A wireless router transmits around 100mW which is +20dBm. A cellphone outputs around 1W which is +30dBm ...
To sum up, your reading of the signal strength is perfectly normal, and unlikely to be the cause of your connection issues!
