[Blind-sysadmins] Router/modem recommendations?

Hello, Currently I'm using a standard linksys router for internet connection. Also, I have a nas from Western digital. I'd like to change my modem to a new and good one. Which devices are you using? Which one do you recommend and why?? Will use gigabyt Ethernet and wifi together, will use at home, it must be good for device cache for longtime usage you know. Thanks. -- Can Kırca
