software ?? tak sure but info kat bawah mgkin bleh membantu.. software utk detect signal lemah or power banyak la.
Need to enhance wireless internt signal?
You can boost the signal range of a WiFi computer network in several ways:
* reposition your router (or access point) to avoid obstructions and radio interference. Both reduce the range of WiFi network equipment. Common sources of interference in residences include brick or plaster walls, microwave ovens, and cordless phones. Additionally, consider changing the WiFi channel number on your equipment to avoid interference.
* upgrade the antenna on your router (or access point). WiFi antennas on most wireless base stations can be removed and replaced with more powerful ones.
* add another access point (or router). Large residences typically require no more than two APs, whereas businesses may employ dozens of APs. In a home, this option requires connecting your primary wireless router (access point) to the second one with Ethernet cable; home wireless routers and/or APs don't normally communicate with each other directly.
* add a bi-directional WiFi signal amplifier to wireless devices as needed. A WiFi signal amplifier (sometimes called "signal booster") attaches to a router, access point or Wi-Fi client at the place where the antenna connects. Bi-directional antennas amplify the wireless signal in both transmit and receive directions. These should be used as WiFi transmissions are two-way radio communications.
* add a WiFi repeater. A wireless repeater is a stand-alone unit positioned within range of a wireless router (access point). Repeaters (sometimes called "range expanders") serve as a two-way relay station for WiFi signals. Clients too far away from the original router / AP can instead associate with the WLAN through the repeater.
