Cagliari and Alghero are two of the most attractive Sardinian bases for people who want to combine remote work with life near the Mediterranean. Both can offer fast fixed internet at suitable addresses, but choosing between them should not be reduced to a single citywide Wi-Fi speed figure. In Italy, fiber availability can vary from one street—and even one building—to another, so remote workers should verify the exact apartment or accommodation before signing a long rental.
Sardinia's underlying broadband picture has improved substantially. Data from AGCOM's Broadband Map for the second quarter of 2026 indicate that FTTH fiber reaches 86.91% of households in Sardinia, above the national figure reported in the same dataset. That is encouraging for remote workers, but it does not mean that every address in Cagliari or Alghero has an FTTH connection.
Why exact Wi-Fi speed is the wrong comparison
It is tempting to ask whether Cagliari or Alghero has “faster Wi-Fi,” but Wi-Fi is only the final wireless connection between a device and a router. The quality of a remote-work setup also depends on the fixed line entering the property, the internet plan, router quality, network congestion and the number of people sharing the connection.
AGCOM's official Broadband Map is designed precisely for this problem. It allows users to check connectivity down to an individual address and reports available access technologies and estimated performance. AGCOM also notes that real-world browsing quality can depend on radio conditions, physical lines and simultaneous sharing of network resources.
For anyone renting for a month or longer, the practical solution is to ask the landlord or host for the exact connection type—preferably FTTH rather than a generic claim of “fast Wi-Fi”—and a recent speed test from inside the property. Then check the address against AGCOM's Broadband Map where possible.
Cagliari: more urban infrastructure for a work-first stay
Cagliari is Sardinia's largest urban center and offers a more conventional city environment for someone whose working week comes first. Dedicated coworking is available: Coworking Sardinia, for example, operates from Via Calamattia 21 and advertises high-speed Wi-Fi, shared and private workspaces, meeting rooms and additional business services.
That kind of infrastructure can be important when an apartment connection fails or when a remote worker needs a quiet place for calls. Cagliari also provides the broader services expected from a regional capital, making it easier to build a routine that is not dependent on the tourism season.
The city has its own airport and rail connections to other parts of Sardinia. For workers who travel regularly or need more everyday services within reach, those practical advantages can matter as much as raw broadband speed.
Cagliari is therefore particularly worth considering for people who expect to work full weeks, take frequent video calls or stay through autumn and winter. The important caveat remains the same: connectivity should be checked at the exact accommodation rather than assumed from the neighborhood or city name.
Alghero: smaller scale with the sea built into daily life
Alghero offers a different rhythm. Its compact historic center, waterfront and beaches make it possible to combine work with a distinctly coastal lifestyle without living in a large city. It also has its own airport, an important advantage for a town of its size.
For remote workers who value walking, the sea and a smaller urban environment, Alghero can be an appealing base. The trade-off is that the city has a more pronounced tourism season than Cagliari, and remote workers should pay particular attention to accommodation availability and what remains open outside the busiest months.
Internet performance again depends on the address. A modern apartment with FTTH in Alghero can be a better working environment than a poorly connected property in Cagliari, which is why citywide speed claims are not enough to make the decision.
What remote workers should verify before booking
Before paying for a long stay in either city, ask for a recent speed test showing download, upload and latency. Upload performance matters for video conferencing and transferring large files, while latency can affect calls and real-time collaboration even when the headline download speed looks impressive.
Ask whether the connection is private to the apartment or shared with other units. Confirm whether the router is inside the property and whether there is a desk or practical workspace near it. For jobs where losing connectivity would be costly, check mobile coverage as well and keep a phone hotspot or second SIM as a backup.
Remote workers should also consider their working hours. Someone employed by a U.S. company may spend much of the Sardinian afternoon and evening online because of the time difference. A beautiful apartment above a busy restaurant or nightlife street may become less attractive once daily calls begin.
Cagliari or Alghero?
The two cities suit different versions of remote life. Cagliari offers the broader urban ecosystem, including established coworking facilities and the services of Sardinia's principal city. Alghero offers a more compact coastal setting where the historic center and sea are central to everyday life.
For internet connectivity alone, however, there is no responsible way to declare one city universally faster. Sardinia now has extensive FTTH coverage, but fixed-network availability remains address-specific. The most reliable decision is therefore made at building level: verify the exact connection, request a current speed test and keep a backup connection for critical work.
For a digital nomad choosing between Cagliari and Alghero, the better question is not simply “Which city has faster Wi-Fi?” It is “Which city gives me the lifestyle I want—and which specific apartment gives me the connection I need?”
