Well, I don't know about professionals but I'm here!
I replaced that exact router a few years ago as I wanted faster wireless. Initially I bought the D-Link DIR###(can't recall model but it's outdated anyway now) because it had some really flexible functionality. Unfortunately it simply would not play nice with my Sonos system no matter what I did - random unexplained disconnects. I switched back to the old router and everything worked perfect so I knew it wasn't the Sonos system. I returned the D-Link and bought a Linksys and have been going trouble free for over 3 years. Have only rebooted a few times. I like other D Link products but my best success on routers has been with Linksys. YMMV.
I am equally baffled by the cable question, can you add more details?
