If your team complains about slow internet, laggy video calls, or delayed cloud apps, the problem is usually inside the network, not with your ISP.
Here are the 10 bottlenecks BahatiGroup finds most often during on-site assessments
1. Old 100Mbps switches
Huge bottleneck. Upgrade to Gigabit or 10Gb for real performance.
2. Misconfigured VLANs
Wrong tagging → broadcast storms → slow speeds.
3. Overloaded Wi-Fi channels
Especially common in offices with multiple APs.
4. Damaged or cheap ethernet cables
Replace with Cat6+.
5. Underpowered routers
Consumer routers choke under business load.
6. Firmware that’s years old
Outdated firmware = slow + insecure.
7. Incorrect DNS servers
Slow DNS resolution = slow everything.
8. Overlooked power issues
Weak UPS = network resets & drops.
9. Old printers or IoT devices flooding traffic
These can clog up the network silently.
10. Congestion on your ISP line
Often fixable with QoS, caching, or dual-WAN failover.
