So I ordered the DPG502 router and a 2nd comcast cable connection, installation was a snap, here are the results:

After downloading for 1 minute.

Using something to split up sessions.


Totally awesome, I can download headers from newsgroups while streaming live music and vides with no slowdowns.

Practical notes for dual-WAN setups: these devices usually provide two main benefits - higher aggregate throughput for many simultaneous connections and resilience when one link fails. New outgoing TCP connections are typically steered across available links, so many parallel transfers scale well, but a single long-lived TCP flow will generally remain bound to one upstream. Provider-side bonding is required to make a single stream exceed a single-ISP limit.

Verification steps include a single-flow throughput test and a multi-stream test. iperf3 is a convenient tool - start a server on a LAN host and run a client with multiple parallel streams to observe aggregate versus per-flow limits. Example:

# on server
iperf3 -s

# on client (8 parallel streams)
iperf3 -c <server_ip> -P 8

Common mitigations and configuration checks: use policy-based routing or static NAT for services that need a stable source IP (VPN endpoints, hosted services). Increase NAT/state table capacity and tune connection timeouts when many clients share the gateway. Watch for asymmetric routing when combining different ISPs - stateful firewalls and VPNs are sensitive to path changes, so lightweight health checks and appropriate route weights help avoid mid-session drops.

Monitoring and maintenance matter: track per-link latency, packet loss and bandwidth, and use SNMP or small agents to capture trends and trigger failover. When weighing cost versus benefit, focus on concurrent-user counts and uptime requirements rather than only headline single-stream numbers. Appreciation to for sharing real-world results in this thread and to for the practical cost/use perspective; both viewpoints help set realistic expectations for testing and configuration.

Wow... but can I ask how much that costs? I don't mean anything by this, but do you really, really need all that speed?

My Comcast connection is approx 3Mbps. I know two 3Mbps connections does not really equal 6Mbps, but it's still really fast. Are you doing some kind of mission critical work in addition to having a desire to stream music and download headers at the same time? Personally, I've never noticed that much of a slowdown while performing those tasks simultaneously...

It was around 200, but you can get a 402 and it will do exactly the same thing, minus the UPnP and the QoS.

For newsgroup downloads, I can hit my 10gb cap in less than 5 hours. :D

I also have a lot of computers on my network so it really hits when they all get on.
