I have a cisco/linksys wireless router connected to a cable modem. Also a belkin universal range extender in another part of the house, which picks up the wireless router signal and boosts it - but not very strongly. The belkin RE can also be used as an access point. Can I run a wire & connect it to the cisco/linksys wireless router? Will my laptop pick up the wireless signal from either device depending where in the house it is?
