Just upgraded to the latest firmware (2.50) for my rev.C DI-624 and I just cant handle how slow has become the internet. After trying to change some settings, I had to go back to the previous firmware (2.42). For now I'll stick to the old firmware because 2.50 seems to be buggy as hell.
I upgraded the firmware to v2.50 a few weeks ago and did not experience any slowdowns. I did experience numerous router reboots. Like you, I went back to v2.42.
When version 2.5 initially becmae available, I upgraded my DI-624 rev C with it. The firmware appeared very buggy so I downgraded back to version 2.42. Yesterday, I decided to try the 2.50 again. The reason being is that my Netgear WG511T notebook card now supports XR so I wanted to see how well they communicated together with XR enabled. So far, it is great. I see no degradation in speed, no reboots and no quirks in my system. We'll see if it continues to perform smoothly.
Update - Funny enough, my old cablemodem failed on my coincidentally while I was experiencing these problems. The modem was a Motorola Cybersurfer which appears to be a 'CLDP' modem. Needless to say, my provider is swapping those out (since it's very old, and I've had it since around 1998) They replaced it with a new Motorola Surfboard DOCSIS 2.0 modem. With the new modem, I then thought to upgrade the firmware to 2.50 on a whim...Turns out it worked! So it appears the Dlink doesn't like specific modems, and my old one looks like one of them. Bear in mind I played with all the modem specific settings (ie. WAN speed, which is pretty much the only setting I think there is?) In any case, hope this helps any other users, as I was at my wits end on it.
