Multiple Issues: Slow Speed, Network Map Error, Phantom Satellite

Firmware:V3.2.16.6_1.4.4

ISP Modem: Zyxel C3000Z

Provider: Century Link 1gbps up/ down fiber

Home sq ft: ~6,500

3 satellites and distances:

  • ~30 ft to RBS upper level 1 (wireless backhaul)
  • ~30 ft to RBS upper level 2 (wired backhaul)
  • ~30 ft to RBS lower level (wired backhaul)
  • RBR on main level

Have been using this system without fail (aside from a reset once or twice) for more than 6 months.  Full 1gbps wired and wirelessly on devices that support those speeds, ~500 mbps for all others.  Was out of town for four days and as some point the network went down losing connectivity to both wired backhaul satellites, wireless backhaul satellite stayed connected as did the router.  Multiple remote reboots tried but they would not come back online.

 

Fast forward to getting back home, the only way to get the satellites to reconnect was to unplug everything (RBR, RBS, Modem) and plug in one at a time.  I have connectivity again across all satellites, which is great, however, the speeds are 1/3 to 1/2 of what they were prior to this issue.  Plugging directly into the modem gives me full 1 gbps speed up and down, so I am fairly confident the issue lies with the RBR/ RBS.  Further, the network map is now wrong.  It is showing the lower level wired backhaul as connected wirelessly to RBR (was previously showing wired) and the upper level wired backhaul as connected wired but to the lower level satellite (was previously wired to RBR).  The upper level wireless backhaul is showing connected wirelessly to the RBR as it should.

 

The phantom satellite looks to be a MyQ garage door opener.  Based on an earlier search it appears the only way to eliminate that would be to hard reset the system.

 

Any ideas?

    Whelp, appears to be the switch.

     

    I tested hardwired speeds at the modem and RBR, found both to be near 1gbps.  Tested at the switch in an open port and saw speeds drop to 1/3-1/2.  Reset the switch and speeds are where they should be at the switch and wall plates.

     

    Looks to have fixed the network mapping issue as well.  I am going to leave the phantom satellite in place for now.  I do not want to deal with factory resetting everything and setting back up manually and I am concerned a backup file would "reload" the phantom satellite.

     

    Thanks for your help.  I should have thought to check at the switch and RBR prior to posting.
