I have an Obi202. I'm having no dialtone & no access to router's webpage. The power light is solid green, the green internet LED is flashing, and I have a solid green light on both phone lines. I'm having to unplug my Obi202 device to get it working again. It will work fine for about an hour or two, then suddenly there will be no dial tone on both phone lines. I enabled DMZ in the router's home page, per self-help troubleshooting, but I'm still having this problem. Advice, anyone?
