Magenta Speed Test — Austria's Cable Giant
Magenta Telekom is Austria's second-largest broadband provider, the local subsidiary of Deutsche Telekom that acquired the former UPC Austria cable network. This acquisition is the key to understanding Magenta: the majority of its broadband customers connect via HFC (Hybrid Fibre Coax) — the old cable TV infrastructure — not through dedicated fibre.
In Austria's broadband market, Magenta competes primarily against A1 (the national telecom incumbent with DSL and growing FTTH) and Drei (Hutchison, offering fixed wireless 5G). Your Magenta speed test result is shaped by whether you have cable or fibre — and, on cable, by how many of your neighbours are heavy internet users.
Magenta Plans — Cable vs. Fibre
| Plan | Download | Upload | Technology |
|---|---|---|---|
| Internet 250 | 250 Mbps | 25 Mbps | HFC Cable |
| Internet 500 | 500 Mbps | 50 Mbps | HFC Cable |
| GigaKraft 1000 | 1,000 Mbps | 50 Mbps | HFC Cable (DOCSIS 3.1) |
| Fiber 500 | 500 Mbps | 100 Mbps | FTTH Fiber |
| Fiber 1000 | 1,000 Mbps | 200 Mbps | FTTH Fiber |
The critical difference: on cable (HFC), upload is severely limited — 25-50 Mbps regardless of download tier. On fibre (FTTH), upload is 100-200 Mbps. For video calls, cloud backups, and streaming to Twitch, this upload gap matters enormously. If you work from home, check whether fibre is available at your address before choosing the highest cable tier.
The UPC Legacy — Why Cable Slows Down
Magenta inherited UPC Austria's coaxial cable network — originally built for one-way cable television. The technology (DOCSIS 3.0/3.1) adapts this cable for two-way internet, but the coaxial segment is shared among homes in your building or street.
During peak hours (19:00-22:00 in Austria), when neighbours stream Netflix, download games, or run updates, the shared cable segment becomes congested. This is why your 500 Mbps plan might drop to 350 Mbps at 20:00 but test at full speed at 14:00.
Magenta is gradually upgrading to FTTH (Fibre to the Home) in new-build areas and major cities, which eliminates this shared-cable problem entirely. Check magenta.at/internet with your address to see if fibre is available.
Connect Box and Fiber Box 2 — Your Equipment
| Feature | Connect Box (Arris) | Fiber Box 2 (Sagemcom) |

| Technology | HFC Cable (DOCSIS 3.1) | FTTH Fiber |
| Wi-Fi | Wi-Fi 5 (802.11ac) | Wi-Fi 6 (802.11ax) |
| Admin URL | 192.168.0.1 | 192.168.0.1 |
| Password | admin / admin (or bottom sticker) | Bottom sticker |
| Bridge Mode | Via Mein Magenta app or support call | Via admin panel |
LED Status Guide
- Solid white: Online and working. Normal operation.
- Solid red: Connection error — the modem cannot register with Magenta's network. Check the coaxial cable is firmly screwed in (hand-tight). If using fibre, check the SC/APC connector.
- Blinking red: Network access denied or firmware update in progress. Wait 15 minutes. If persistent, call support.
- Blinking green: Searching for downstream/upstream signal. Normal during boot (2-5 minutes). If persistent, the line has a problem.
The Coaxial Splitter Problem
Many Austrian apartments have a coaxial wall splitter that divides the signal between your TV and your internet modem. A faulty or low-quality splitter can severely degrade your speed — sometimes cutting it in half. If your speed test is significantly below your plan:
- Check if the Connect Box is connected through a splitter.
- Try connecting the coax cable directly to the wall outlet, bypassing the splitter entirely.
- If speed improves, replace the splitter with a high-frequency rated one (5-1218 MHz for DOCSIS 3.1).
Bridge Mode — Using Your Own Router
Magenta allows Bridge Mode on the Connect Box, which turns it into a pure modem and lets you use your own router (FRITZ!Box, ASUS, Ubiquiti). The process:
- Open the Mein Magenta app or call 0676 2000.
- Request Bridge Mode activation for your Connect Box.
- Connect your own router to the Connect Box via Ethernet.
- Your router handles all routing, Wi-Fi, and firewall functions; the Connect Box handles only the cable modem connection.
Austrian Broadband Competitors
- A1 — Austria's national incumbent. VDSL and growing FTTH network. Lower speeds on DSL but excellent fibre where available. Best coverage nationwide.
- Drei (3) — Fixed wireless 5G home internet. Good in urban areas with 5G coverage. No cables needed but speeds fluctuate with signal conditions.
- LIWEST — Regional cable provider in Upper Austria (Linz, Wels, Steyr). Similar HFC technology to Magenta but with less congestion due to smaller customer base.
Magenta support: Call 0676 2000 or 0676 200 7777 for technical issues. The Mein Magenta app handles router restarts, Störung (outage) reports, and Bridge Mode requests.
