My sis couldn't connect to the internet at her boyfriends place. Roadrunner internet Cable modem --> Linksys router --> Computer. Suddenly they had no internet connection. She calls Roadrunner, and they say your connection to the modem is fine, Call E-machines. She calls E-machines tech support and they tell her nothing is wrong with the computer and direct her to Linksys. Linksys trouble shoots and tells her that with her model of router, is not compatible with Vista. Has anyone heard of such a thing? Comon, my d-link router is years old, and infact D-link 2 years ago put it on the "End of Life" list.. I have vista and no issues. Edit: I should also add, This e-Machine running Vista has been on the internet with this router for a few weeks before.. He told her its and intermittent issue and they know about it. Perhaps I missed it, but I never heard of a router not being compatible with an OS. Network is network, right? I mean Windows, Linux, Unix. Network data is network data.
