So the time came yesterday..dun dun dun...big box from new egg.  Inside it was the 890 router and some cat7 cable.  Decided it was time to switch out all my cat 5 cable ( yes I know, dont mock me).  I will admit to being worried about all this.  I bought the asus 87u when it first came out, and had nothing but problems with it.  And here I am purchasing another expensive router that is very new to the community.
My isp is Baja Broadband.  I pay for 50mb down and 5mb up.  Of course I never really see that speed except during off hours at like midnight.  But I am fine with that, as Iong as I get close.  Well about 5 months back, pretty soon after getting that asus router, i started having major problems.  Huge packet losses and speeds below 25 mb during peak hours.  The packet loss was so bad I was unable to play some games like neverwinter and I could only play on one server with World of Tanks.  What games were playable I would get lag spikes lasting 5 to 10 sec.  I just accepted it was my isp causing this, which they couldn't figure out the problem, and knowing I was going to be moving soon, I didn't fight it.  Well there was enough weird things going on with my asus router, like constantly having to reset it, I wondered if my router was causing the problems all along.  What I couldn't accept though is that a router would cause me packet loss.  Well damn the torpedoes, lets get this dlink router.
I can happily say with some frustration, that it was practically all the router.  Now I am not running any complicated setups.  I have mixed wired and wireless connections with no bridges.  Haven't tuned much on the router, a lot is at default settings.  Have not messed with firewall settings.  Matter of fact the only thing that isn't default is I turned on the multicast settings and changed the router's ip to 192.168.1.1.  That is it, and everything is glorious.  Everything connected no problems and I am getting almost 0 packet loss.  Speed is better at 35 mb during peak hours.  Probably my isp there but I will take that with no packet loss.
I have nothing ill to say of this router at this time.  It is doing exactly what I want it to do.  Time will tell though.  If I can help anybody out with problems/troubleshooting please feel free to ask here or email me.  Please understand though, my scope of networking knowledge is limited.
Cheers
