Ucast V461 Fix -

The Problem: You have three 5G SIMs and WiFi. The Q461 shows "Connected" on all four links, but your stream buffers every 10 seconds.

The Deep Diagnosis: Bonding is not "more sticks = better." It is about latency parity. If one SIM card has a ping of 30ms and another has a ping of 300ms (due to carrier congestion), the Ucast’s bonding algorithm has to wait for the slow packet before reassembling the frame. That wait causes the buffer. ucast v461 fix

The Fix:

Modern routing suites utilize "Nexthop Groups" to bundle multiple next-hops for ECMP (Equal-Cost Multi-Path). In v461, there was a flaw in the reference counting of nexthop IDs. The Problem: You have three 5G SIMs and WiFi

To provide a permanent fix, one must understand the underlying code logic typically found in the zebra daemon (the routing manager) of the v461 family. If one SIM card has a ping of
