Yes I do believe it is safe to say that most households do have more than one game console, or gaming pcs' in the network frame.
I don't post on this forum a whole lot since my issues with the DGL 4500 have been resolved. I am somewhat baffled that a router like the 890L does not have a full cone NAT.
I had the 4500 online with 5-6 game consoles. Although the DSL ISP I had to use because it was them or WIFI didn't leave me with much bandwidth, maybe .5-.7 MBPS on the up and at the peak I was seeing 6.119 MPBS down. Either way, the devices used never saw anything but an open NAT on dashboard and in game. Now gaming on the other hand was a different story. Not the routers fault! Even with the kids' friends coming over and running their consoles on the WIFI ...still open. Logging in on the Admin page and seeing all the allocated IP addresses not set up in DHCP was a nightmare. The router still handled the traffic.
Moving On!
I am baffled to see that the 890L does not support a full cone NAT. I expected to see a few glitches and FW updates after I purchased this router, but now I'm not so sure about my purchase. I bought it when we finally received a cable upgrade (it increasing is getting faster) I now have 12+MBPS up and over 120MBPS down. I was excited when I read about this router. I have been a fan of Dlink since I bought my 4500 and my DSL modem. But with todays blazing internet speeds there should have been some forethought in the development of this router. More and more cities are seeing fiber networks and the speeds are insane. Everywhere you look there are data centers being built and I have heard that it's going to last 10+ years. ISP speeds will get faster and faster. But what good does it do if the router will not handle multi-platform gaming. Maybe I should have bought a router from the local Hardware store.
What is actually the point? Seems like PS network, XBL do not seem to concerned. The information they have posted seems to be outdated. Looking at the pages for XBL network troubleshooting is mind numbing. It's like calling and getting a Tier one tech support from your ISP, or that automated B.S. " have you checked your cable", "unplugged your modem or router?" Like I'm under 12 or over 70.
Time for network hardware developers, XBL, PS network, to step the game up and try and keep up with ISP capabilities. Otherwise multiplayer or multi-platform gaming is out of the question. We all might as well go back to Dial-up.
If the DGL 4500 or 5500 would handle my upload and download I'd have no problem moving it to my other service.
I know next time before I drop a $300 bill I'll read more and maybe save myself a few bucks. Read more reviews on other products that do support a full cone NAT. Just like in gaming, once they start developing another game or the next BF or COD... the don't worry about those servers so much. Moving on to newer generation of routers must be the same. If there is no concerns with fixing this issue then... we could consider multiple connections from the same ISP, I could run 2 or 3 different modems from the same location and still be under what I pay a month for the one connection I have now. Then all the gaming devices would have an open NAT without the cost of a router.
OK, I am done now
