When having Wi-Fi connection problems, most of us instinctively look at the bars on our computer or phone screen to see how strong our Wi-Fi connection is. That's the equivalent of checking the oil level in your car by looking for the warning light on your dashboard – it only tells you about your car's oil level in the most approximate way. There are much more precise tools available.
You can measure signal strength several different ways. Sometimes, it's indicated in terms of network speed, as in how many Mbps the network allows you to upload data. But this is only a user-friendly approximation: It's officially measured in decibel milliwatts (dBm).

Decibels are expressed as negative numbers, and the closer to zero the number, the stronger the signal. In other words, the larger the absolute value, the weaker the network connection. For example, -80 dBm is a much weaker connection than -30 dBm.
In addition, signal strength isn't linear; it's logarithmic, which means that every 3 dBm change represents a halving or doubling of the strength of the signal. Moreover, a 10 dBm change adds up to ten times more or less strength.
Here are some guidelines for assessing your signal strength:
- -30 dBm. This is the maximum signal strength you could achieve, and it probably means you are within a couple feet of the Wi-Fi router.
- -50 dBm. Anything from -30 dBm to -50 dBm is excellent and is often about as high as you can get.
- -67 dBm. This is the lowest value that will deliver acceptable results for most online services.
- -80 dBm. This is the lowest possible value that will make a connection between the router and computer, but it's too weak to be useful for any online service.
How to improve your Wi-Fi signal
If your Wi-Fi signal is weak, there are a lot of possible causes, and your troubleshooting options are extensive. Some of the simple fixes include:
- Make sure your Wi-Fi router is positioned in a central place in your home or office.
- Ensure the router's antennae are positioned optimally.
- Move your Wi-Fi transmission to a different, less-crowded channel.

To stay connected with all-day battery life, Surface devices implement wireless connectivity settings that balance performance and power conservation. Outside of the most demanding mobility scenarios, users can maintain sufficient wireless connectivity without modifying default network adapter or related settings.
In congested network environments, organizations can implement purpose-built wireless protocols across multiple network access points to facilitate roaming. This page highlights key wireless connectivity considerations in mobile scenarios utilizing Surface Pro 3 and later, Surface Book, Surface Laptop, and Surface Go.
Prerequisites
This document assumes you have successfully deployed a wireless network that supports 802.11n (Wi-Fi 4) or later in accordance with best practice recommendations from leading equipment vendors.
Configuring access points for optimal roaming capabilities
If you’re managing a wireless network that’s typically accessed by many different types of client devices, it’s recommended to enable specific protocols on access points (APs) in your WLAN, as described in Fast Roaming with 802.11k, 802.11v, and 802.11r. Surface devices can take advantage of the following wireless protocols:
- 802.11r. “Fast BSS Transition” accelerates connecting to new wireless access points by reducing the number of frames required before your device can access another AP as you move around with your device.
- 802.11k.“Neighbor Reports” provides devices with information on current conditions at neighboring access points. It can help your Surface device choose the best AP using criteria other than signal strength such as AP utilization.
Specific Surface devices can also use 802.11v “BSS Transition Management Frames,” which functions much like 802.11k in providing information on nearby candidate APs. These include Surface Go, Surface Pro 7, Surface Pro X, and Surface Laptop 3.
Managing user settings
You can achieve optimal roaming capabilities through a well-designed network that supports 802.11r and 802.11k across all access points. Ensuring that your network is properly configured to provide users with the best wireless experience is the recommended approach versus attempting to manage user settings on individual devices. Moreover, in many corporate environments Surface device users won’t be able to access advanced network adapter settings without explicit permissions or local admin rights. In other lightly managed networks, users can benefit by knowing how specific settings can impact their ability to remain connected.
Recommended user settings and best practices
In certain situations, modifying advanced network adapter settings built into Surface devices may facilitate a more reliable connection. Keep in mind however that an inability to connect to wireless resources is more often due to an access point issue, networking design flaw, or environmental site issue.
Note
How you hold your Surface Pro or Surface Go can also affect signal strength. If you’re experiencing a loss of bandwidth, check that you’re not holding the top of the display, where the Wi-Fi radio receiver is located. Although holding the top of the display does not block wireless signals, it can trigger the device driver to initiate changes that reduce connectivity.
Keep default Auto setting for dual bandwidth capability
On most Surface devices, you can configure client network adapter settings to only connect to wireless APs over 5 gigahertz (GHz), only connect over 2.4 GHz, or let the operating system choose the best option (default Auto setting).
To access network adapter settings go to:
- Start > Control panel > Network and Sharing Center > your Wi-Fi adapter > Properties > Configure > Advanced.
Keep in mind that 2.4 GHz has some advantages over 5 GHz: It extends further and more easily penetrates through walls or other solid objects. Unless you have a clear use case that warrants connecting to 5 GHz, it’s recommended to leave the Band setting in the default state to avoid possible adverse consequences. For example:
- Many hotspots found in hotels, coffee shops, and airports still only use 2.4 GHz, effectively blocking access to devices if Band is set to 5 GHz Only.
- Since Miracast wireless display connections require the initial handshake to be completed over 2.4 GHz channels, devices won’t be able to connect at 5 GHz Only.

Note
By default Surface devices will prefer connecting to 5 GHz if available. However, to preserve power in a low battery state, Surface will first look for a 2.4 GHz connection.
You can also toggle the band setting as needed to suit your environment. For example, users living in high density apartment buildings with multiple Wi-Fi hotspots — amid the presence of consumer devices all broadcasting via 2.4 GHz — will likely benefit by setting their Surface device to connect on 5 GHz only and then revert to Auto when needed.

Roaming aggressiveness settings on Surface Go
Wifi Signal Strength Meter
Front-line workers using Surface Go may wish to select a signal strength threshold that prompts the device to search for a new access point when signal strength drops (roaming aggressiveness). By default, Surface devices attempt to roam to a new access point if the signal strength drops below Medium (50 percent signal strength). Note that whenever you increase roaming aggressiveness, you accelerate battery power consumption.
Leave the roaming aggressiveness setting in the default state unless you’re encountering connectivity issues in specific mobile scenarios such as conducting environmental site inspections while also maintaining voice and video connectivity during a conference meeting.

To enable roaming aggressiveness on Surface Go:
Wifi Speed Test
- Go to Start > Control Panel > Network and Internet > Network and Sharing Center.
- Under Connections select Wi-Fi and then select Properties.
- Select Client for Microsoft Networks and then select Configure
- Select Advanced > Roaming Aggressiveness and choose your preferred value from the drop-down menu.

Conclusion
Surface devices are designed with default settings for optimal wireless connectivity balanced alongside the need to preserve battery life. The most effective way of enabling reliable connectivity for Surface devices is through a well-designed network that supports 802.11r and 802.11k. Users can adjust network adapter settings or roaming aggressiveness but should only do so in response to specific environmental factors and revert to default state if there’s no noticeable improvement.
