I only get a wifi connection when I am next to the wifi hub. I lose the signal when I move 4 meters from the hub. Other laptops pick up the wifi without problem. I have tried using the zenbook on main


It's may be the laptops Antenna? Wire broken, pinched, damage, connection loose. The Antenna is usually behind the monitor, wires run from the wireless adapter through the hinges and attach to the antenna, Maybe a loose connection on the Wireless adapter itself? Sometimes you can access through a bay door on the bottom of the laptop, sometimes you have to disassemble the laptop/keyboard, depends on the Asus Model. Have you connected a Ethernet cable?

My laptop stopped picking up wifi after a much needed modification. I have a 3 year old hp pavilion dv9000. the hinges broke so I decided to remove the monitor of the laptop and hook it up to a desktop...


That is because the WI-FI antenna wires were on the LCD panel behind the glass.

Currently your laptop base has no signal. The only solution is that you may pick up a signal with the base alone, if it is near the wireless router about 20' (3 meters).

How do i increase wi-fi signal strength


There are only a few ways to increase signal strength ..move closer to the source (the router) , get a bigger antenna or boost the signal...you can boost the signal with foil in the shape of a parabola around the router antenna or make one out of a vegatable strainer that will plug into the laptop(this one works best )especially for picking up your neighbors WIFI

Excellent signal low speed transfer


You can boost the signal range of a WiFi computer network in several ways: Answer:
  • 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.

My wifi will only work inside buildings


wireless has limited range and can be affected by walls, doors, glass. Some models of routers if they have removable antenna's can be replaced by highgain antenna's which can drastically improve your range.
