Summary: I went through three of these units thinking there must be something wrong with the hardware on the first two. Well after configuring it every way possible, including with full help and analysis by D-Link tech support, I can tell you with 100% certainty that this is a PIECE OF JUNK. Even set down to its simplest modes of operation it, I could not get it to operate for 25 hours in a row.
Summary: I was hoping to use this router for my small business, but it turns out the wireless is so bad that I just won't be able to use this as our primary router. Connections to websites consistently time-out. HTTPS connections especially seem to cause problems for it. I will say the LAN portion of the router works great, however who does a wired connection anymore? Everyone uses laptops or tablets, so this just won't fly as a router.
Summary: I have had good experiences with DLink in the past. However this DSR-500n was not well received. I chose this router due to my previous experience with DLink and also the Dual Wan capabitlites it provided. I recieved the first one in the mail. It would not produce a wireless signal and I could not connect to the GUI to make any modificiations. I contacted DLink, after some troubleshooting, the issue was determined to be hardware related.
Summary: I bought this router because it is suppose to support 2 Internet providers. I configured it and both ISPs were intermittently available. I spent about 8 hours on the phone with technical support over 4 days. They could not fix the problem. I looked like such a fool to my boss for recommending it over Cysco. I returned the router to Amazon and they are deliberating as to whether to give me my money back.
Summary: I bought this router for a hefty price back in April 2011. Router is single band Wifi. Initially was really crappy wireless. Couldn't even stream Youtube over Wifi.But is fixed after the firmware upgrade. VPN doesn't work tried PPTP, it connects but nothing goes thru. Tried every option and it just doesn't work. Called customer support and they took my username and password and says it works from their end.
