Leverage open-source DD-WRT firmware and not D-Link one
on February 9, 2012
Updated Aug 6, 2015 - Thanks to grip929 for providing the link http://dd-wrt.com/wiki/index.php/D-Link_DIR-632 and so far my router has not dropped Wi-Fi signals or needed any reboots (unless I did it for a memory/cache refresh).
Updated Sept 10, 2015 - Still no issues and running like its supposed to be.
Updated March 29th 2012 - I have been working with D-Link development team and review an updated firmware that is supposed to eliminate a lot of the problems we see today, and mentioned below. I will update this review after testing.
I have quite a few end-user devices in my house (nearing 25 at last count) and some of them require Ethernet connectivity. So between this DIR-632 8-port router and two other 4-port D-Link routers (which acts as an Access Point or modified-switch) I have a medium-sized LAN in my networked house. Thus it does not help when your router decides to shut-down wireless transmission (every day or every other day) and you have to physically go down and reboot the sucker unless you are lucky and one Ethernet port is working so you can reboot using the D-Link web-interface.
As a network engineer and a long-time D-Link user, I spent 2 months reviewing how to eliminate the problem and then realized there is no work-around because of how the Firmware (1.01NA) is on the DIR-632. I have gotten 3 replacements (2 refurbished, one new) and Tech support (which is typically very good on how fast they respond) provided me development firmware (from their Taiwanese team) to see if the problem would go away and it did not. So prior to returning one of the RMA devices (DIR-632) I utilized an Open-source router firmware called DD-WRT (for this specific router) and the problems (rebooting, dropped connections) never happened again.
1. DD-WRT interface is not for the faint-of-heart but there is enough information out there (on the support forums) to show you how to use it - This is similar to rooting your Android phone or Nook-Color reader etc.
2. Another problem with the D-Link router and 1.01NA firmware is that it causes problem with Cisco Network Magic Pro software causing the network-magic service to terminate unexpectedly.
3. Overall a bad product despite the 8-LAN ports (which no other vendor offers at this price range) and if you have the heart to use the Open source software then you will be fine. Remember D-Link will not support you ("officially" when you use non D-link firmware), but "unofficially" they agree that the open-source DD-WRT firmware does not cause any problems with D-LINK DIR-632.
