No, if you are going to post, try not to make it worthless, like this one. If you have a bad opinion about something, at least give some kind of reason for it. "yes, worthless" isn't an answer, helps no one, and makes you look like a post padder. (For further clarification, "Because they suck" wouldn't be valid either.)
PERSONALLY, D-Link is my networking brand of choice. I have (no longer in use) a D-Link WBR-2310 wireless G router that worked well for over 3 YEARS, with the only reboots coming from firmware upgrades, and config changes. Wireless signal was EXCELLANT in the whole house on my ex's laptop, and the only time the signal dropped for her was when I booted her for being on the computer too long. OYE. It is no longer in service, because with my Voice/Video/Internet, I neet to use their special Residentail Gateway to split the VOIP from the data. It's built (I believe by Cicso [Linksys], but I am not 100% on that. The Set top boxes are Cisco.) I DID have the WBR-2310 set up without DHCP working as JUST a wireless access point, but the only devices I have that are wireless are my iPhone, and PSP, neither of which need Wifi access, so it is powered down until such time as I need it.
Currently in use is a DNS-323 NAS drive on my network with two Seagate 500 Gig hard drives. This has a uPNP server out of the box that I use to stream music,movies, and pictures to both of my PS3's on my wired network. Box has gigabit ethernet too. It has been in service on my network for over 2 years, and the only downtime it has had was firmware upgrades, and when I changed from RAID 1 to JBOD. Well, actually, it has a Thermal sensor on it, and you can program it to shut down once it reaches a certain temp, and it did this about 3 times last summer when my office got up over 110*. Both the NAS and my computer shut down actually. Now it sits in the basement on my network rack, and hasn't needed to power down due to temps again.
Lastly, I have a D-Link DGS-1024D at the core of my network. It is a 24 port switch, each port supporting 10/100/1000. I have a patch panel that has 3 runs of Cat5e to each room (2 runs of 3 for the living room), and each port from the patch panel is wired into the switch. Got the switch in late October, or Early September, and it is running like a CHAMP. I've had 4 set top boxes viewing TV shows at the same time, 3 PC's downloading from the internet, and 2 PS3's watching different movies served off of the DNS-323 at the same time, and the switch wasn't bogged down at all.
Personally, I am not a big fan of Belkin, as I had one of their routers, and it didn't function well, and kept rebooting itself every few minutes, and their tech support was a total joke, and tried to tell me it was faulty electrical wiring at my premise.... not even going to get into that.
I haven't ever OWNED Cisco networking hardware (not really counting the Set top boxes, since I didn't purchase them), but I have had friends and family use them before, and to me, they come off as really finicky. Sometimes they just choose not to work, or wireless won't work with encryption enabled. Even my set top boxes for video service are finicky at times, and stop communicating with the ATT server, and needed rebooting.
For me, D-Link is the only one I choose.
