SB8200: Link Aggregation Setup

« Go Back


How do I enable Link Aggregation on my SB8200 modem?
The Link Aggregation Control feature, available on firmware version 200.174F and later, combines the two wired connections between the SB8200 and a Link Aggregation capable router to achieve Internet speed up to 2 Gbps.  If used with Internet speeds above 1 Gbps the SB8200 can provide Ethernet redundancy in case one of the wired connection fails.  If one Ethernet connection fails, the other Ethernet connection will only provide Internet speeds of up to 1 Gbps.

  • Greater than 1 Gigabit Internet Plan
  • 2 Ethernet connections
  • Enable Link Aggregation in the SB8200
  • Enable Link Aggregation in the Wi-Fi router 
CAUTION: Performance is degraded on client devices when Link Aggregation is enabled only on the SB8200.   Link Aggregation must be enabled on both the SB8200 and Wi-Fi router.
