WiFi is acting up

What's likely happening is either a power brownout is causing the two modems to reset and/or the Fusion modem (the one with only 4 lights) is either having trouble connecting to a wireless tower or registering with the wireless network. This means you have regular satellite internet but the Fusion part is down. Without Fusion being fully operational you will have an immense lag playing games.

Recommend trying the following, which might get Fusion to connect properly:
1. At no time should you press any red buttons on the back of either device, nor eject the SIM on the back of the Fusion modem (WL3000).
2. If the SIM has been ejected and is sticking out from the Fusion modem, make sure it's popped back into place before proceeding further.
3. Locate the power bricks to both devices.
4. Disconnect the power cord from both bricks, noting which box loses power when you disconnect either.
5. Wait 60 seconds.
6. Re-connect one of the power cables back to the brick connected to the modem with six lights first (HT3000W).
7. Then reconnect the other power cable to the brick connected to the modem with only four lights (WL3000).

The HT3000W will fully connect in about a minute, but the WL3000 may take between 6-10 minutes to fully connect and register. Your WiFi will be unstable during this time as it cycles between standard satellite and Fusion registers with the system. If after 10 minutes you still see Signal and System lights flashing on the WL3000 there is still a problem with being able to connect to the wireless network, likely requiring more help from a rep here or a tech visit.

You may want to also look at the following link using a device that is connected to the network, which may give you more clues to what is going on:
https://192.168.10.1/limited.html#!/diagnostics/instant_graphs

The information on that page should be as follows:
1. A normal Fusion system should have RSRP (wireless signal level) with a number more positive than -110.  Note that a number like -120 is more negative and means the wireless signal is very marginal.
2. Public Internet: Up
3. Acceleration Appliance Status: Good - though you may see some bouncing around between this and Blackout/Brownout from the period when you rebooted the Fusion device.
4. Acceleration Tunnel Status: Not Enabled (not even sure that's implemented, tbh)
5. Management Connectivity Status: Established - though you may see two spikes MGMT Disabled from the period when you rebooted the Fusion device.
6. Wireless Receive Signal Statistics and Quality: Ignore that for now. Too complicated to explain here.
7. Wireless Receive Channel: Should show a single line for a single channel number. If it's frequently jumping around to different numbers it means it's having a problem locking on to a specific wireless channel from the nearby tower.
8. Wireless Access Technology: EUTRAN.

Hope this helps.
