Low Internet Speed Despite High-Speed Plan in Bilimora: What to Do
You are on a 100 Mbps or 200 Mbps Nisan plan, but a speed test shows only 30–50 Mbps. Or your YouTube keeps buffering even though you pay for a fast plan. This is a different problem from a general slow internet connection — you have a high-speed plan, but something between the fiber and your device is reducing the actual speed you receive. This guide walks through every likely cause and how to fix each one.
Cause 1: Old Router With a Speed Cap
This is the single most common cause of low speed on a high-speed plan. Older routers — especially those made before 2018 — often have a maximum throughput of 100 Mbps regardless of what your plan offers. If you are on a 200 Mbps plan but your router is a 4–5 year old model, it will cap your effective speed at 100 Mbps or less.
How to check: Look at the model number on the bottom of your router and search its specifications online. Look for "LAN port speed" and "WiFi maximum throughput."
Fix: Nisan provides a modern dual-band router with all new connections. If you have an old router, call +91 98251 52400 — Nisan may be able to upgrade your device.
Cause 2: WiFi Band (2.4 GHz vs 5 GHz)
Your router broadcasts on two frequency bands. The 2.4 GHz band has longer range but lower maximum speed — typically 40–150 Mbps even with a fast plan. The 5 GHz band is faster (up to plan speed) but has shorter range.
Many devices default to 2.4 GHz. If your laptop or phone is connected to the 2.4 GHz network, your speed test will show 40–70 Mbps even on a 200 Mbps plan — not because the plan is slow, but because the WiFi band is the bottleneck.
Fix: In your phone's WiFi settings, disconnect and manually connect to the network ending in "5G" or "_5GHz". Test again. You should see significantly higher speed.
Cause 3: Distance and Walls Between You and the Router
Concrete walls in Bilimora homes absorb WiFi signal significantly. If your device is two or more rooms away from the router with walls in between, you may receive only 20–40% of the router's maximum WiFi output — regardless of your plan speed.
Fix options:
- Move the router to a more central location in your home
- Use an ethernet cable from the router to your device for maximum speed
- Add a WiFi extender or mesh system to cover distant rooms
Cause 4: Too Many Devices on WiFi
If 15–20 devices are connected to your WiFi, the router's processing capacity is spread across all of them. Even idle connected devices use some router memory. If your router is an older or entry-level model, many connected devices can reduce its performance.
Fix: Disconnect devices you do not actively use from WiFi. Log into your router's admin panel (typically 192.168.1.1 in your browser) to see a list of connected devices and remove unfamiliar ones.
Cause 5: Device Limitation
Some devices cannot receive the full plan speed. An older phone from 2015–2018 may have a WiFi chip that supports only up to 150 Mbps theoretically — and much less in practice. Testing from such a device will show low results even if your connection is perfect.
Fix: Test from multiple devices. If a newer phone or a laptop shows the correct speed but an older phone does not, the old device is the bottleneck — not your internet plan.
Cause 6: ISP-Side Issue
If all the above checks pass (tested via ethernet, modern router, good device, result still low), the issue may be on the network side. This can happen after:
- A fiber cable fault that was partially repaired
- Incorrect plan configuration in Nisan's system
- Equipment issue at the distribution node
Fix: Call Nisan at +91 98251 52400, tell them your speed test result (number from the ethernet test), and request a line check. Nisan's team can remotely check your line quality and correct any configuration issues, or schedule a technician visit if needed.
Quick Diagnosis Checklist
- Test speed via ethernet cable → matches plan? WiFi is the issue. Does not match? Go to step 2.
- Restart router (power off 30 seconds, back on) → retest → still low? Continue.
- Check router model age — is it 5+ years old? Router may be the cap.
- Call Nisan at 98251 52400 with your speed test result. They will diagnose remotely.

Why is my internet speed slow despite a high-speed plan?
Common causes are WiFi signal loss (walls, distance from router), old router hardware, device limitations, or peak-hour congestion. Test via ethernet cable first to isolate whether the issue is WiFi or the connection itself.
How do I fix slow internet speed in Bilimora?
Connect via ethernet cable and run a speed test. If wired speed is normal, the issue is your WiFi setup. If wired speed is also low, call Nisan at +91 98251 52400 for a line check.
What should I do if Nisan internet is slow?
First restart your router. Then test via ethernet. If speed is still low, call Nisan at 98251 52400 with your ethernet speed test result. Nisan's team can remotely diagnose and resolve most issues.
Why does 2.4 GHz WiFi show lower speed than my plan?
2.4 GHz WiFi is limited to 40–70 Mbps due to the frequency band, even on a 200 Mbps plan. Switch your device to the 5 GHz network for speeds above 100 Mbps over WiFi.
