Name the feature accurately
Failover changes to another path when the preferred one is unavailable. Load balancing distributes eligible traffic according to a policy. Bonding or another aggregation design can involve additional technology and endpoint support. These are different arrangements despite similar marketing language.
Read the actual router documentation and provider conditions. A setting named load balance does not establish a bonded internet service. Nor does a router's total traffic graph prove that one media connection uses both links at once.
Work a single-flow example
Suppose an illustrative home has a 50 Mbps link and a 20 Mbps link. The arithmetic sum is 70 Mbps, but a single flow assigned to the 20 Mbps path does not acquire 70 Mbps merely because the other link exists. Several eligible flows may use the available links differently.
The example describes a basic distinction, not a prediction for a specific router or media session. A segmented application can create multiple requests, and policy details matter. Do not assume that every request is balanced independently or that doing so is always appropriate.
Check session consistency
An application can depend on a stable outward address or related session context. The router vendor may offer documented policies for keeping applicable traffic on one WAN. Use those controls through the administrator rather than guessing ports or rotating paths to bypass an account rule.
Record whether the actual fault is speed, a connection transition or permission after an address change. Those require different investigations. A successful combined speed display cannot certify an account's media path.
Evaluate the intended viewing configuration
Test the same permitted item under the documented policy and record both the active path and visible result where possible. Include optional competing traffic and the observation time. Keep a way to restore the original arrangement.
Before paying for another access plan, identify whether extra aggregate household capacity or actual failover is the goal. If one existing stream already works reliably, a larger total number may add no benefit to that task. Account allowances and service terms remain separate from the number of internet links.

Can dual-WAN failover interrupt an existing stream?
Yes, a path change can require connection recovery. Actual continuity depends on the router, application and service behaviour.
