port80 wroteLinksys quality decreased over the years once they were great but now they are just overpriced name tags.
I bought a Linksys X3000 modem/router combo shipped straight from the UK a month ago and it was a shiny piece of cr*p.
Bad wireless security
Not nearly getting a good signal as advertised
Speed also not nearly good as advertized
I reverted back to my 5 year old trendnet.
All Linksys routers/modems or any other wireless devices have bad wireless coverage. But it mostly depends on where you've placed the device. If you have 10 walls passing through it that of course the wireless won't be good.
What's wrong with WPA2 and MAC filtering ?
Also your speed defers depending how you've configured the router.
