Updated October 2026 · For small offices and anyone tuning a router
Before paying for a faster plan, check your router. Outdated firmware, a crowded Wi-Fi channel or a poorly placed router can cut your speed in half. These settings and fixes often make a noticeable difference in minutes.
Always note your current settings before changing anything so you can switch back.
- Update router firmware first.
- Use the 5 GHz or 6 GHz band and a clear channel.
- Place the router centrally, off the floor and away from metal.
- Quality of Service settings protect calls and video.
1. Update the Firmware
Manufacturers release updates that fix bugs, improve performance and close security holes. Log in to the router’s admin page or app and install the latest firmware.
2. Choose the Right Band and Channel
- Use 5 GHz or 6 GHz for speed; 2.4 GHz reaches farther but is slower and more crowded.
- Use auto channel selection, or pick a channel neighbors are not using.
- Use 20 MHz channels on 2.4 GHz and 40 to 80 MHz on 5 GHz in busy areas.
3. Improve Placement
Put the router in a central, open spot at desk height or higher, away from microwaves, metal cabinets and thick walls. In larger offices, one router is rarely enough; multiple access points give better coverage than a stronger single router.
4. Turn On Quality of Service (QoS)
QoS lets the router prioritize voice and video over downloads and updates. In a business, giving calls and video meetings priority keeps them clear even when someone is uploading a large file.
5. Check Other Settings
| Setting | Recommendation |
|---|---|
| Wi-Fi security | WPA2 or WPA3; never open |
| DNS | Use a reliable, fast DNS provider |
| Guest network | Separate from business devices |
| Unused features | Turn off what you do not need |
Test Before and After
- Run a speed test from a computer plugged into the router.
- Run the same test over Wi-Fi from your usual desk.
- Change one setting at a time.
- Repeat both tests and keep only the changes that help.
If the wired test is fast and Wi-Fi is slow, focus on Wi-Fi settings and placement. If both are slow, the issue is likely the plan or the provider.
Business Networks Need More Than a Router
Consumer routers are built for a few devices in a home. Offices with dozens of devices, guest Wi-Fi and VoIP phones need business-grade firewalls, switches and access points, with separate networks and centralized management. Managed Wi-Fi keeps settings correct and up to date without your staff having to log in to anything.
When the Router Is the Problem
If your router is several years old, lacks current Wi-Fi standards or cannot reach your plan speed in a wired test, replace it. Businesses benefit from business-grade routers and managed Wi-Fi. And if a wired test shows the plan itself is slow, it may be time for faster service such as fixed wireless internet in Detroit.

Frequently Asked Questions
What router setting increases internet speed?
Updating firmware, using the 5 GHz band on a clear channel and enabling QoS usually make the biggest difference.
Does router placement matter?
Yes. A central, elevated position away from walls and metal can significantly improve Wi-Fi speed.
Should I buy a new router?
If your router is old or cannot reach your plan speed over a wired connection, a newer router is worth it.
