Modern laptops are designed to look stylish but sometimes the quest for looks puts the wireless antennae in such a place that it only works in the presence of a very strong signal from the router.
Using a high gain wireless adapter may, in certain circumstances, assist with connection and speed.
For example we stock the TP-Link High Gain USB wireless adapter in our computer shop in Perth.
At just £19.99 inc VAT, this is a very cheap way to add wireless to your desktop or to help a laptop that is struggling to connect to a wireless router.
