I found you info on line when trying to get my DSR-500n to work correctly. I have two internet connections and everything was working fine, lan 1 was the primary and it would drop over to wan 2 when it lost connection. All was well until I did a firmware upgrade, which crashed, tech from Dlink tried to do it and gave up, sent me a replacement with the latest firmware as of last month. Now when using the DSR-500n my speeds are running so slow, web pages take 5-7 seconds to load, tried resetting to factory no difference. If I miss out the dlink speeds are back to 30mb download and 5 up, connect back through dlink 10mb down and 5 up, this is hard wired. dlink are sending another one but I am starting to lose faith with tech support. Any help would be appreciated. Also since doing the firmware update I keeps showing wan 1 up with all the correct details but wan 2 no ip address, restore firmaware back to a year ago and both wans show up

• What Hardware version is your router? Look at sticker under router.
• Link>What Firmware version is currently loaded? Found on the routers web page under status.
• What region are you located?

Internet Service Provider and Modem Configurations

• What ISP Service do you have? Cable or DSL?
• What ISP Modems Mfr. and model # do you have?
• What ISP Modem service link speeds UP and Down do you have?
• If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works. To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.
  Example of a D-Link router configured for PPPoE with ISP Modem bridged: PPPoE Configuration on Router
• Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
• For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
