TL;DR: The right networking setup is the difference between a productive office and one where half your team is waiting for files to load. Whether you run a 10-person shop in Mirpur or a 3-floor corporate office in Gulshan, this guide covers what a proper business network costs (from ৳15,000), which hardware actually works in Bangladesh, what security basics you can’t skip, and how to avoid the most expensive mistakes business owners make when setting up their office network.
This guide is based on direct conversations with IT managers at Dhaka-based SMEs, vendor quotes collected from networking companies across Gulshan, Uttara, and Motijheel, and real-world setup experiences from businesses that went through network installations in 2024–2025. Pricing data was verified in January 2026.
What Is a Business Networking Solution — and Why Does It Matter?
A computer networking solution is the combination of hardware, software, and configuration that connects your office computers, printers, servers, and internet to each other. Think of it as the circulatory system of your business. Without it, nothing moves.
For Bangladeshi businesses, poor networking is one of the most silent killers of productivity. A garments buying house in Tejgaon with 20 staff sharing a single consumer-grade router loses an estimated 2–3 working hours per employee per week. Dropped video calls. File transfers that take forever. A Google Drive sync that’s always behind. That adds up fast.
The good news: proper business networking is no longer reserved for large corporations. Small and medium businesses across Dhaka, Chittagong, Sylhet, and Rajshahi are now setting up professional networks for ৳20,000–৳80,000 — a one-time investment that typically pays back within months.
The 4 Types of Business Networking Solutions in Bangladesh
Getting the network type wrong is the most expensive mistake businesses make. They end up either paying for enterprise features they’ll never use, or buying consumer-grade equipment that collapses under business load. Here’s what each option actually means in practice.
1. Local Area Network (LAN)
A LAN connects devices within a single physical location — one office floor, one building. This is the backbone of almost every business network in Bangladesh.
A properly configured LAN includes a managed switch, structured Cat6 cabling through walls and ceilings, and a central patch panel. Brands like Cisco, TP-Link, and Netgear are common here. If your office is in a rented space in Banani or Dhanmondi, any vendor who quotes without visiting your office first is one to avoid.
Typical LAN cost in Bangladesh: ৳15,000–৳60,000 for a 10–30 node office, depending on cable runs, switch quality, and whether structured cabling is included.
2. Wireless LAN (Wi-Fi Network)
Business Wi-Fi is very different from the router you have at home. A TP-Link TL-WR840N handling 25 staff is a setup failure we’ve seen repeatedly — it works for 5 users and crawls after that.
Business-grade Wi-Fi uses access points from Ubiquiti UniFi, Cisco Meraki, or TP-Link Omada. These support multiple access points managed from a single dashboard, dedicated bands for staff vs. guests, and seamless roaming between floors.
For a 2-floor office in Gulshan, a properly installed Ubiquiti UniFi setup with 3–4 access points costs approximately ৳35,000–৳70,000 installed — hardware, mounting, and configuration included.
3. Wide Area Network (WAN) and Multi-Site Connectivity
If your business has more than one office — a head office in Dhaka and a branch in Chittagong, for example — you need a WAN setup that connects them securely.
In Bangladesh, this is typically done through dedicated MPLS leased lines (expensive, used by banks and large corporations) or site-to-site VPN over standard broadband (cost-effective for SMEs). BDCOM Online, Link3 Technologies, and Fiber at Home are among the ISPs that offer business-grade dedicated connectivity for multi-site setups.
4. Cloud-Managed Networks
This is the direction most growing businesses are moving in 2026. Cloud-managed networking means your routers, switches, and access points report to a central cloud dashboard. Vendors like Cisco Meraki and Ubiquiti UniFi offer this.
The practical benefit for Bangladeshi businesses: your IT person — or an outsourced networking company — can monitor and fix most issues remotely, without sending a technician to your office every time something goes wrong.
What a Real Office Network Setup Looks Like
Here’s a real-world example from a 25-person marketing agency in Dhaka’s Mohakhali area, based on a setup completed in late 2024.
The agency had been running on a single TP-Link consumer router for 18 months. Zoom and Google Meet calls dropped constantly. File transfers between staff were painfully slow. The team had just accepted this as normal.
The networking vendor started with a site survey — measured the floor, identified concrete walls that would block Wi-Fi signals, and counted which devices needed wired versus wireless connections. This step alone took 90 minutes and fundamentally changed the hardware recommendations.
The final setup:
- 1x Mikrotik RB450Gx4 router (traffic management and load balancing across two ISPs)
- 2x ISP connections — Amber IT as primary, Digicon Telecom as backup
- 1x 24-port TP-Link managed switch
- 3x Ubiquiti UniFi AP-AC-Lite access points
- Structured Cat6 cabling to 12 desktop workstations
- A separate VLAN for guest Wi-Fi
Total cost: ৳68,000 for hardware and installation. Monthly ISP cost: ৳8,500 for the dual-connection setup.
The agency owner said: “The first week felt like we’d upgraded the entire office. Zoom calls stopped dropping. I hadn’t realized how much time we were losing every day.”
The single most impactful addition was dual ISP failover. When one ISP goes down — which happens regularly in Dhaka during heavy rain — the router automatically switches to the backup line. No manual intervention. No lost client calls.
The Most Common Networking Problems Bangladeshi Businesses Face
These aren’t theoretical problems. They’re what IT managers and business owners across Dhaka and Chittagong actually deal with.
ISP outages at the worst possible moments. Even reliable ISPs like Carnival Internet and Summit Communications have unplanned outages. Businesses without a backup connection — a second ISP or a 4G LTE failover — lose working hours they can’t recover.
Consumer-grade routers doing business work. Walk into almost any SME office in Dhanmondi or Mirpur and you’ll find a ৳1,500 home router. These are not designed for 20+ concurrent users. They can’t prioritize VoIP calls. They overheat. And when they fail, the entire office stops.
No network segmentation. When your staff computers, your file server, your IP cameras, and your guest Wi-Fi all run on the same network, one infected laptop can spread malware to everything. According to Cisco’s Annual Cybersecurity Report, most SME breaches happen through exactly this kind of flat network architecture — not through sophisticated attacks.
Sloppy cabling. Cheap network installations in Bangladesh often use substandard cable or skip testing entirely. A badly terminated cable causes intermittent drops that are genuinely maddening to diagnose. Insist on proper cable testing — with an actual cable tester — before signing off on any installation.
No network documentation. After the installation team leaves, many businesses have no record of their IP address scheme, switch port assignments, or VLAN setup. When something fails six months later, troubleshooting starts from zero.
Business Networking Costs in Bangladesh: 2026 Pricing
These are real market prices, not estimates. They reflect what businesses are actually paying across Dhaka, Chittagong, and Sylhet in early 2026.
| Setup Type | Office Size | Approx. Cost (৳) |
|---|---|---|
| Basic LAN (unmanaged switch + cabling) | 5–10 nodes | ৳12,000–৳25,000 |
| Standard LAN (managed switch + Cat6) | 10–20 nodes | ৳25,000–৳55,000 |
| Wi-Fi only (2–3 Ubiquiti APs) | 20–30 users | ৳30,000–৳60,000 |
| Full LAN + Wi-Fi | 20–30 nodes | ৳55,000–৳1,00,000 |
| Enterprise Wi-Fi (Cisco Meraki) | 50+ users | ৳1,50,000–৳4,00,000+ |
| Dual-ISP failover router setup | Any size | ৳15,000–৳40,000 additional |
| Server rack + patch panel | Any size | ৳20,000–৳80,000 additional |
Monthly ISP costs for business broadband in Dhaka typically run ৳3,000–৳15,000 depending on speed and provider. One honest limitation worth noting: pricing in Chittagong, Sylhet, and Rajshahi tends to be 10–20% lower for labor, but hardware prices are similar nationwide since most equipment is imported.
How to Choose a Networking Company in Bangladesh
This is where most businesses make expensive mistakes. Here’s what to actually look for.
Insist on a site survey before any quote. A vendor who quotes over the phone hasn’t seen your cable runs, your wall materials, or your floor plan. Site surveys should always be free.
Ask specifically about cable testing. After installation, every cable run should be tested with a proper cable tester — something like the Fluke Networks DSX CableAnalyzer. If the vendor says they test “manually,” that’s not sufficient for a professional installation.
Ask about post-installation support. What happens if something stops working three months later? Most reputable networking companies in Bangladesh offer Annual Maintenance Contracts (AMCs) for ৳10,000–৳30,000 per year — covering unlimited support visits plus parts at cost.
Verify hardware sourcing. Networking hardware sourced from grey markets in Bangladesh is a real issue — products without proper warranty or quality control. Legitimate distributors include Star Tech, Ryans Computers, and Techland BD. Ask for official invoices.
Get at least 3 quotes. Pricing varies enormously between vendors in Dhaka. The most expensive is not always the best. The cheapest almost always cuts corners.
Networking by Business Type in Bangladesh
Different businesses have different networking needs.
Garments and RMG sector: Factories in Ashulia, Gazipur, and Narayanganj need networks that handle barcode scanners, CCTV systems, and management office connectivity simultaneously. Fiber backbone cabling is worth the extra cost in large factory buildings — it handles the bandwidth requirements that Cat6 starts to struggle with at scale.
IT companies and software firms: Offices in BSEC, BASIS Software Technology Park, and the Kawran Bazar tech corridor need high-throughput networking with low latency. Managed switches with QoS (Quality of Service) configured for VoIP are essential, not optional.
Retail and e-commerce: WooCommerce operations and Daraz seller setups need reliable point-of-sale connectivity. A network outage during a peak sales event — Daraz’s 11.11 sale, for example — is a direct revenue loss that’s hard to recover.
Healthcare clinics: Patient data privacy under Bangladesh’s Digital Security Act and general data protection best practices means your EMR (Electronic Medical Records) system should never share a network with your waiting room Wi-Fi.
NGOs and development organizations: Many NGOs in Mohakhali and Tejgaon need secure VPN connectivity to international headquarters. A cloud-managed network makes this seamless and auditable.
Network Security: The Part Most BD Businesses Skip
A poorly secured business network in Bangladesh is a genuine liability. In 2024, several Dhaka-based businesses were hit by ransomware attacks that encrypted their file servers. In most cases, the entry point was a poorly secured Wi-Fi network or a router still running default credentials.
According to Verizon’s Data Breach Investigations Report, 61% of SMB breaches involve credential attacks — meaning attackers simply logged in with a username and password they already knew or guessed. That’s not sophisticated hacking. That’s basic negligence.
Here’s the minimum security baseline every Bangladeshi business network needs:
Change default credentials on every device. “admin / admin” is the default on most TP-Link and Mikrotik routers. If your networking company leaves these unchanged, your network is open to anyone who looks up the default credentials for your router model — which takes 10 seconds on Google.
Put guest Wi-Fi on a separate VLAN. Any visitor who connects to your Wi-Fi should be on an isolated network that cannot reach your file servers, printers, or internal systems.
Keep firmware updated. An unpatched router from 2022 running its original firmware has known, publicly documented security vulnerabilities. Router manufacturers release patches — check yours every quarter.
Configure the firewall properly. Most business routers include firewall functionality. Mikrotik routers — popular in Bangladesh for their cost-to-performance ratio — require explicit firewall rule configuration. A router that’s installed but not configured is providing false security.
Disable WPS (Wi-Fi Protected Setup). WPS has well-documented security vulnerabilities, detailed in research published by the US Cybersecurity and Infrastructure Security Agency (CISA). Disable it on every access point.

Frequently Asked Questions
What is the minimum budget for a professional office network setup in Bangladesh?
For a 5–10 person office, a professional LAN with a managed switch, Cat6 cabling, and a business-grade router starts at ৳15,000–৳25,000. Wi-Fi access points add ৳8,000–৳20,000 each depending on brand. Consumer-grade setups cost less upfront but fail under real business loads — and the lost productivity costs far more than the savings.
Which Wi-Fi brand is best for small offices in Bangladesh?
For offices under 30 users, TP-Link Omada gives the best value — affordable access points, free cloud management software, and local distributor support. For businesses needing more advanced features, Ubiquiti UniFi is the most widely used professional option in Bangladesh. Cisco Meraki is excellent but comes at an enterprise price that’s only justified for 50+ user environments.
Do I need a dedicated server for my office network?
Not necessarily. Many Dhaka SMEs use NAS (Network Attached Storage) devices from Synology or QNAP instead of full servers — they cost ৳30,000–৳80,000 with drives, consume far less power, and handle file sharing and backups well for offices up to 30 users. A dedicated server makes sense when you’re running custom software, a local database, or an ERP system.
How do I set up dual ISP failover in Bangladesh?
You need a router with dual WAN support — Mikrotik is the most popular choice locally. Subscribe to two ISPs using different infrastructure (one fiber, one on a separate backbone). The router is configured to detect when the primary connection fails and automatically route traffic through the backup. This setup costs ৳15,000–৳40,000 in additional hardware and configuration on top of your base network.
What is an AMC (Annual Maintenance Contract) for networking?
An AMC is a fixed annual fee for ongoing network support — troubleshooting visits, configuration changes, and parts at cost. For small-to-medium office networks in Bangladesh, AMC pricing runs ৳10,000–৳30,000 per year. Worth it if your business depends on network uptime: you get predictable costs and guaranteed response times instead of emergency call-out rates.
How long does a business network installation take in Dhaka?
A 10–20 node office network takes 1–2 days for installation when cabling is being run fresh. Multi-floor setups with structured cabling take 3–5 days. Configuration and testing add another half day. Plan for at least one business day of partial disruption — better to schedule over a weekend if your office can’t afford downtime.
The Bottom Line
Business networking in Bangladesh is more affordable than most owners expect — but it does require making the right decisions. Get a site survey before committing to any vendor. Don’t run business loads on consumer hardware. Build in ISP redundancy if your work depends on internet connectivity. And don’t let a vendor sign off on an installation without proper security configuration.
A network built properly in 2026 will serve your business reliably for 5–7 years. One built on shortcuts will cost more in downtime and replacement than you saved at the start.
