We have a set of dell corporate laptops. Can we extend the wifi’s range on them to be able to pick up signals further away? We are working with Windows Vista and 802.11 G wireless mini pci cards.

Thanks. We'll let you know when a new response is added.

The wireless card has its limitations set. The only thing that can be extended is the wireless access point or router’s range. This can be extended by the use of repeaters and signal boosters. I am afraid there is nothing you can do from the standpoint of the range of the wireless card in the computer itself.

    Well, I think that is not completely true Technochic. A wireless card with a better antenna will certainly be able to pick up weaker signals.

    And MIMO technology will get you more range and/or higher throughput at a given range.

    The issue is he has an embedded solution (mini-pci G) on a laptop which does not allow for modification of the antenna (they are embedded into the laptop shell) or card. The only options left are on the base station side: more access points, repeaters or some type of add-on signal boosting antenna at the AP. All which Technochic has pointed out. The best solution is to increase the APs or add repeaters. Using antennas to boost signal strength for transmit and receive is tricky and subject to many potential issues. It works OK in small locations. YMMV If this is a large location, a professional signal survey of the facility can determine the appropriate number of APs and their optimal location to avoid creating blind spots in coverage. While MIMO works to give better range and throughput with other MIMO components, it does not help with standard G (or B) units.
