Can you still connect to the internet? (Edit: I realise your title says "no connectivity," but I wanted to make sure you actually had no access).
Tonight my husband accidentally unplugged the ht2000w modem. When I plugged it back in, it cycles on but the system light never comes on. Not sure how this happened. I have tried to restart several times but it remains the same. Any ideas how to fix this?
Preferably using a LAN cable connected device, what do you see listed for a State Code in the System Summary box near the top of this modem page?
On the same page, what do you see listed for your Satellite Receive Signal Strength in the WAN Info box on the bottom left?
