Quick answer
Should you get a backup connection for Starlink?
Yes. Starlink goes down every day — an always-on dish averages about 34 minutes of downtime daily from routine satellite handoffs. A second connection keeps you online when Starlink drops.
What’s the best backup connection for Starlink?
A 4G/5G cellular hotspot or SIM is the most practical backup for most Starlink users — it works anywhere Starlink works, requires no installation, and uses a different network so outages rarely overlap. Cable or DSL broadband is a strong option if you have it at a fixed location. A second Starlink dish is also possible if you need maximum throughput.
How do you use two internet connections at once with Starlink?
Speedify combines Starlink with any other connection — cellular, cable, Wi-Fi, or a second dish — into one bonded connection. Speedify runs on your phone, laptop, or router. When Starlink drops, Speedify moves your traffic to the backup instantly, so calls don’t cut out and downloads don’t stall. Speedify is free to try.
71% of Speedify’s Starlink users already run a second connection. The data below shows why.

What Starlink WAN Aggregation Means for Business Networks
WAN aggregation combines multiple wide-area network connections into a single higher-capacity, more resilient internet path. For businesses deploying Starlink alongside other internet connections, WAN aggregation means Starlink’s satellite bandwidth is added to your total available throughput rather than operating as a separate connection that devices either use or don’t.
Traditional hardware WAN aggregators on dedicated appliances from vendors like Peplink, Cradlepoint, and Mushroom Networks aggregate WAN connections at the session or flow level. Each session is assigned to one WAN interface. Aggregate download and upload speeds are improved because different sessions use different connections, but no single session benefits from multiple WAN connections simultaneously.
Speedify takes a different approach. Speedify’s channel bonding technology aggregates WAN connections at the packet level, not the session level. A single active session, like a video upload, a VPN tunnel, a live stream, draws bandwidth from all aggregated WAN connections at the same time. Your team gets closer to the combined upload and download capacity of all internet connections, not just the capacity of one.
For a business running Starlink delivering 150 Mbps alongside a wired Ethernet broadband connection delivering 100 Mbps and a 4G/5G cellular connection delivering 80 Mbps, Speedify’s WAN aggregation can provide up to 95% of the combined 330 Mbps capacity in optimal conditions. This is available to individual sessions, not just spread across sessions.
How Speedify Combines Starlink Internet and Other WAN Connections
Speedify’s channel bonding technology routes all internet traffic through a single encrypted Speedify tunnel. Inside that tunnel, Speedify monitors latency, packet loss, and jitter on each WAN connection every few milliseconds and distributes packets across all active connections based on real-time performance.
Key behaviors of Speedify’s WAN aggregation:
- Packet-level distribution. Individual packets from a single session are sent across multiple WAN connections simultaneously. The receiving Speedify server reassembles them in order. The application sees a single high-throughput internet connection.
- Dynamic rebalancing. If Starlink satellite congestion causes latency to spike, Speedify reduces the share of traffic going through Starlink and increases the share going through wired Ethernet or 4G/5G cellular automatically. When Starlink recovers, Speedify rebalances again.
- Seamless failover. When a WAN connection fails entirely, packets that were on that connection are immediately rerouted through the remaining aggregated connections. Active sessions don’t reset. VoIP calls don’t drop. VPN tunnels stay established.
- Internet connection prioritization and data limits. Network admins on Speedify Teams plans can configure which WAN connections carry the most traffic, set data limits on metered connections like 4G/5G cellular, and apply rate limits per connection.
Starlink WAN Aggregation Configurations with Speedify
- Starlink internet plus wired Ethernet broadband. For businesses with both Starlink and a ground-based ISP connection, Speedify aggregates both into a single higher-capacity path. Either connection serves as automatic failover for the other. Combined upload and download speeds exceed either connection individually.
- Starlink internet plus 4G/5G cellular plus wired Ethernet. Three-WAN aggregation. The highest throughput and most resilient configuration available without dedicated fiber infrastructure. Any single WAN connection can fail without affecting internet availability. All three contribute to combined upload and download bandwidth when healthy.
- Dual Starlink dishes plus 4G/5G cellular. For remote operations without access to wired broadband, two Starlink dishes aggregated with 4G/5G cellular gives maximum satellite throughput plus cellular redundancy. Speedify distributes traffic across all three simultaneously.
- Starlink with metered 4G/5G cellular backup. For businesses managing cellular data costs, Speedify can aggregate Starlink as the primary WAN and keep 4G/5G cellular active with a configured data limit. Cellular bandwidth contributes to the aggregate until the data limit is reached, then operates in standby mode only.
How to Deploy Speedify for Starlink WAN Aggregation
Option 1: Speedify App on Each Device
- Connect the device to each WAN connection: Starlink via Wi-Fi or Ethernet, additional connections via secondary Wi-Fi networks, additional Ethernet ports, or USB modems.
- Install the Speedify app. Speedify runs on Windows, macOS, Linux, iOS, and Android.
- Speedify detects all available WAN connections and begins aggregating them automatically. No manual WAN interface configuration is required.
- Use Speedify Teams to set connection priorities, apply data limits to metered connections, and manage the aggregation configuration centrally across all team devices.
Option 2: Speedify on a Router for Network-Level WAN Aggregation
- Connect all WAN connections: Starlink, wired Ethernet, 4G/5G cellular modems to a Speedify-compatible router running OpenWrt firmware. The Miri X510 bonding router powered by Speedify supports multiple WAN inputs and is designed for network-level aggregation deployments.
- Speedify aggregates all connected WAN connections at the router level. Every device on the network benefits from the aggregated throughput and automatic failover without per-device software installation.
- Manage WAN priorities, data limits, and connection monitoring from the Speedify for Routers dashboard.
The router-level deployment is the right choice for businesses where WAN aggregation needs to cover the entire site, including IoT devices, networked equipment, and hardware that cannot run the Speedify app directly.

Which Businesses Need Starlink WAN Aggregation with Speedify
- Businesses with multiple available WAN connections but no aggregation layer. Organizations that have Starlink plus an existing ISP connection, but devices can only use one at a time, benefit immediately from Speedify’s WAN aggregation. Both connections contribute to throughput and provide failover for each other.
- Remote sites with high concurrent user counts. A remote office or field site where many team members are simultaneously on video calls, uploading files, and using cloud applications needs more aggregate bandwidth than a single Starlink dish provides. WAN aggregation with Speedify combines available connections to meet that demand.
- Operations requiring both throughput and uptime SLAs. Businesses that carry their own connectivity SLAs to clients or internal stakeholders need a WAN architecture that doesn’t have a single point of failure. Speedify’s multi-WAN aggregation provides both the throughput and the redundancy those SLAs require.
- IT teams replacing or supplementing hardware WAN aggregators. Network engineers who have evaluated or deployed hardware-based WAN aggregation appliances can use Speedify as a software-defined alternative that runs on existing router hardware or purpose-built devices, without proprietary appliance costs.
- MSPs standardizing multi-WAN deployments across client sites. Managed service providers can use Speedify as a consistent WAN aggregation layer across all client sites, managed from the Speedify Teams dashboard, regardless of what combination of WAN connections each site has available.
