I've had my DIR-655 for a couple of years and I love it. Best router I've ever owned.
Doing okay until tonight. All I did at the router level was change the port number for a webcam in port forwarding and rebooted the router as usual, something I have done several times before without any problems. This was from a wireless connection using a laptop (the one I'm using right now). All of my computers have had Network Magic installed for the last couple of years. Everything is updated on all the computers (three machines).
After the router rebooted to accept the setting (the changed port for the web cam), I went back to my desktop PC and when I tried to do some surfing on the browser, Securespot put up a warning page stating:
"Invalid Arguments. One or more MAC Addresses were not found or are invalid."
All of a sudden I am no longer able to connect to the Internet wireless or wired on this one machine. So, I thought to reboot the PC to clear things up. No dice. I checked ALL of my network settings-everything seems to be the same as it was. Securespot is DISABLED at the router level (I disabled it last year, not impressed with it, and I don't subscribe to the service).
I checked with another laptop and now it, too, gets the same error. Only this one laptop I am using right now seems to be unaffected.
So, I thought, time to check for a new router firmware. Perhaps THAT might clean things up. I went from 1.32NA (11/09) to the latest, 1.33NA (released late January this year). The upgrade went without a hitch. Unfortunately, the same problem as I mentioned above still persists.
I imagine this may have something to do with MAC filtering, which is something Network Magic does through a simple interface and I've never had any problems with it before.
The network connection indicator on the PC shows that I do have local network AND Internet access. But I am unable to do ANYTHING Internet - wise, wired or wireless. The computers can access each other and thus my home wireless network seems to be fine.
How do I get rid of Securespot? I believe it's behind all of this and I'm FED UP with it!!
I would be grateful for any assistance you folks can provide.
