What Crypto Mining Actually Needs from Your Internet
The first misconception about crypto mining is that it requires fast internet. It does not. A single ASIC miner (Antminer S21, Whatsminer M60) communicating with a mining pool uses approximately 50-100 KB/s of bandwidth — less than a single Spotify stream. Even a rack of 10 ASICs uses under 1 Mbps total. A home GPU mining rig running 6 cards on Ethereum Classic or Ravencoin uses similarly negligible bandwidth.
What mining absolutely requires is uptime. Every minute your internet connection drops, your miners sit idle burning electricity — which in Texas still costs money even at the state's low rates — while producing zero hash power and earning zero block rewards. A pool like Foundry USA, F2Pool, or Braiins assigns work to your miners in real time. When the connection drops, the pool reassigns your work units to other miners within seconds. You lose those shares permanently.
The math is simple: if your electricity costs $0.08/kWh and you run 3,000 watts of mining hardware, one hour of downtime costs you $0.24 in wasted electricity plus whatever block rewards those 3,000 watts would have generated — typically $0.30-0.80/hour for a small home setup in current Bitcoin difficulty. An internet connection that drops for 2 hours per week costs you $50-100/month in lost mining revenue. That is more than the difference between a cheap and a reliable ISP plan.
Latency matters moderately. Lower latency means your miner receives new block templates faster after a block is found, reducing stale shares. Stale share rates above 1-2% indicate a latency or connectivity problem. Fiber connections with 5-15ms latency to US-based pools are ideal. Satellite connections with 600ms+ latency (HughesNet, Viasat) produce unacceptable stale rates for serious mining operations.
Uptime vs. Speed — Why 99.9% Matters More Than 1 Gbps
Texas residential internet providers do not publish uptime SLAs for consumer plans, but real-world reliability varies dramatically.
**Fiber providers (AT&T Fiber, Google Fiber, Frontier Fiber)** deliver the best uptime in Texas. Fiber connections are immune to electromagnetic interference, less affected by weather than coax or wireless, and typically achieve 99.95%+ uptime — roughly 4 hours of downtime per year. For mining, fiber is the gold standard.
**Cable providers (Spectrum, Xfinity)** achieve 99.5-99.9% uptime in most Texas markets, but are vulnerable to neighborhood node congestion and maintenance windows. Spectrum in particular performs scheduled maintenance in the 2-5 AM window that can cause 15-30 minute drops 2-3 times per month. For mining hardware running 24/7, these drops add up.
**Fixed wireless (T-Mobile 5G Home Internet)** has the worst uptime profile for mining. Tower congestion, weather sensitivity, and network management policies that deprioritize home internet traffic during peak hours make T-Mobile unreliable for always-on applications. Miners report 2-5 brief disconnects per day on T-Mobile, each causing a few minutes of lost shares.
**The bandwidth you actually need:** 10 Mbps download and 5 Mbps upload is more than enough for even a large home mining operation (10+ ASICs). Buy the cheapest plan from the most reliable provider — not the fastest plan. AT&T Fiber's base 300 Mbps plan at $55/month is wildly overkill on speed but delivers the uptime that matters. Do not pay for 1 Gbps when your miners use under 1 Mbps total.
Top Texas Internet Picks for Home Crypto Miners
**AT&T Fiber — Best overall for mining.** The 300 Mbps plan at $55/month provides more bandwidth than any home mining operation could use, with fiber-grade uptime and low latency. No data caps. AT&T Fiber covers most of the Austin, Dallas-Fort Worth, Houston, and San Antonio metro areas where the majority of Texas home miners operate. This is our default recommendation.
**Google Fiber — Excellent where available.** 1 Gbps symmetrical at $70/month. Slightly more expensive than AT&T Fiber for mining purposes where you do not need the speed, but Google Fiber's uptime track record in Austin and San Antonio is exceptional. If Google Fiber is available at your address and you want the most reliable connection regardless of cost, it is a strong choice.
**Frontier Fiber — Strong in covered areas.** 500 Mbps plan starting at $49/month. Good uptime in Frontier's Texas fiber markets. Worth considering if AT&T Fiber is not available.
**Spectrum — Acceptable with caveats.** $30-55/month plans with cable reliability. The scheduled maintenance windows are the main concern for miners — expect 2-3 brief outages per month during off-peak hours. If Spectrum is your only wired option, it works but is not ideal.
**Avoid for mining:** T-Mobile 5G Home Internet (too many disconnects), Starlink (high latency causes stale shares), HughesNet/Viasat (600ms+ latency makes pool communication inefficient). These are acceptable for household browsing but poor for always-on mining operations.
**Rural Texas miners:** If you are mining in a rural area where only satellite or fixed wireless is available, Starlink is the least bad option. Its 20-40ms latency is acceptable for mining pools, and speeds are sufficient. The issue is reliability — Starlink experiences brief drops during satellite handoffs and weather. Budget for 2-3% downtime and factor that into your profitability calculations.
UPS and Internet Failover — Protecting Your Hash Rate
Texas power grid reliability is a legitimate concern for miners, especially after Winter Storm Uri in 2021 and subsequent summer heat events. A comprehensive mining setup needs both power backup and internet failover.
**UPS for networking equipment:** You do not need to put your ASIC miners on battery backup — they draw too much power for consumer UPS units. Instead, put your router, modem/ONT, and network switch on a UPS. A CyberPower CP1500PFCLCD ($200) provides 30-45 minutes of runtime for networking gear, bridging short power blips that would otherwise kill your internet connection and halt all miners. Most Texas power interruptions last under 5 minutes.
**Dual-WAN failover:** The single most effective reliability upgrade for a home mining operation is a dual-WAN router. A Peplink Balance 20X ($300-400) or TP-Link ER605 ($60) connects two internet services simultaneously. Run AT&T Fiber as primary and T-Mobile Home Internet as failover, or Spectrum primary and a mobile hotspot as backup. When the primary connection drops, the router switches to backup within seconds — your miners reconnect to the pool with minimal lost shares.
**Configuration for mining:** Point your miners at a pool with multiple stratum endpoints in different geographic regions. Foundry USA, for example, has stratum servers in New York, Dallas, and San Jose. If your primary pool endpoint becomes unreachable due to a regional internet issue, miners configured with fallback stratum addresses reconnect to an alternate server automatically.
**Cost justification:** A dual-WAN setup costs $100-400 for the router plus $50/month for a secondary connection. If your mining operation generates $500+/month in revenue, the failover setup pays for itself within 1-2 months by eliminating the 5-10 hours of monthly downtime that a single-connection setup typically experiences. For operations under $200/month in revenue, the UPS for networking gear alone ($200 one-time) provides the most cost-effective protection.
Frequently Asked Questions
How much internet speed do I need for crypto mining?
Very little. A single ASIC miner uses approximately 50-100 KB/s, and even 10 ASICs use under 1 Mbps total. A 10 Mbps connection is more than sufficient for any home mining operation. What matters is uptime, not speed — every minute of internet downtime means lost hash power and wasted electricity. Buy the cheapest plan from the most reliable provider, which in Texas is typically AT&T Fiber at $55/month.
Why is Texas popular for crypto mining?
Texas has some of the cheapest electricity in the US, with residential rates as low as $0.06-0.10/kWh and commercial rates even lower through deregulated power plans. The state also has a crypto-friendly regulatory environment and abundant renewable energy (wind and solar) that further reduces costs. The combination of cheap power and available fiber internet in metro areas makes Texas one of the top states for both industrial and home mining operations.
Should I use Starlink for crypto mining in rural Texas?
Starlink is acceptable for mining in rural Texas where fiber and cable are unavailable. Its 20-40ms latency is sufficient for mining pool communication, and bandwidth is more than enough. The concern is reliability — Starlink experiences brief drops during satellite handoffs that cause momentary disconnections. Budget for 2-3% downtime in your profitability calculations. If possible, pair Starlink with a T-Mobile hotspot on a dual-WAN router for failover.
