I've had the Linksys Wireles-G Broadband Router with Speedbooster (WRT54GS-RM) for 2 years now. Recently bought a Lenovo laptop, everytime that laptop is turned on all the wireless connections stop working. I have 2 Macbook Pros running on the wireless and 1 PC connected directly to the Ethernet cable. So I'm looking to upgrade my router to a faster, secure and wider/longer signal, and of course be able to connect 4 computers at a time. I've heard the Belkin N+ Wireless router is a good choice but I know there are better ones out there. Thanks!
