A weak signal in one room, Wi-Fi drops on one device, and every device disconnecting at once are different problems—and call for different fixes. Map where and when the trouble happens, compare Wi-Fi with a wired connection if you can, then make one change at a time and retest. Start with router placement and other free checks before considering an extender or mesh system.
First, work out what is failing
A slow speed test over Wi-Fi does not, by itself, prove that your broadband service is faulty. Distance, walls, the router, the device, interference and other network use can all affect the result. Take a simple baseline before changing anything.
- Record the pattern. Note the room, device, time, Wi-Fi signal indication and whether other devices lose connection at the same time.
- Test several locations. Run tests near the router and in the problem areas, at more than one time. Repeat tests under similar conditions after each change. Speeds can vary by time, and delay can matter for calls and gaming as well as download speed. Ofcom’s broadband guidance advises multiple tests and checking more than speed alone.
- Compare devices. Check whether the same room affects several devices or whether just one device disconnects. If available, connect a stationary computer to the router with Ethernet and compare its connection with Wi-Fi at the same time.
Use the pattern to choose the next check:
- One room or area is affected: suspect local coverage, obstacles or interference first.
- Only one device is affected in different places: investigate that device’s Wi-Fi settings, adapter, software and power management.
- Several devices disconnect together: check the router and broadband path, not just the room’s Wi-Fi coverage. A repeater cannot repair a provider outage.
Check the router and broadband connection
When several devices drop at once, check whether the router is powered and showing its usual connection status. If your service uses a separate fibre ONT, check that equipment too. Note the time and duration of interruptions. Ofcom’s UK-specific consumer troubleshooting guidance recommends checking the router, boosters or mesh devices, and ONT where installed, and keeping a record of interruptions. If the router or ONT indicates a service problem, contact your provider; adding Wi-Fi coverage equipment is not a fix for a fault upstream of the router.
Restarting the router and affected equipment can help rule out a temporary glitch, but repeated reboots do not solve a persistent coverage problem. Check for available updates to your devices and network equipment. While testing, avoid unnecessary heavy network use where practical so that shared activity is less likely to cloud the comparison.

Improve coverage with free placement changes
Try moving the router before buying equipment. Aim for an open, elevated position nearer the centre of the areas where Wi-Fi is used. Reduce the number of walls and other obstacles between the router and the device. Keep it away from metal, water-filled objects and possible sources of interference such as microwaves, baby monitors, cordless phones, halogen lamps, dimmer switches and speakers. See Ofcom’s Wi-Fi guidance for practical placement advice.
After moving the router, repeat the same tests in the same rooms and, as far as possible, under similar conditions. If the weak area improves but another area worsens, adjust the position and test again. The best location depends on the home’s layout, construction and where people need a reliable signal; a router hidden in a cupboard or tucked behind objects is rarely a useful baseline for diagnosis.

Check for channel congestion
In a dense area, nearby Wi-Fi networks can compete for radio airtime. Use your router’s tools or a Wi-Fi analyzer to inspect nearby networks and channels. Microsoft’s home-layout guidance describes channels 1, 6 and 11 for 2.4 GHz and recommends choosing based on local interference; for 5 GHz, check channel occupancy. An automatic channel choice may work well, but it is worth checking if drops persist.
- Record your current router settings and the baseline results.
- Inspect nearby networks or the router’s channel tools for the band you use.
- If you change a channel, change only that setting, then test the same devices and locations again.
If the signal is strong and the channel does not appear congested, Microsoft notes that 2.4 GHz channel width can be a less common cause of reliability trouble. If the router is set to automatic or 20–40 MHz, trying 20 MHz can be a diagnostic test—not a universal setting to apply to every network. Restore the previous setting if the change does not help.

Troubleshoot drops on one device
If other devices stay connected while one device drops, start with that device rather than changing the whole network. Confirm that its Wi-Fi is enabled, install available operating-system and wireless-adapter updates, and check the manufacturer’s instructions for adapter settings. Microsoft’s Windows Wi-Fi troubleshooting guide includes setting the wireless adapter’s power-saving mode to Maximum Performance. Menu names and available choices can vary with Windows version and driver.
If the device remains unreliable, compare it in another room and, if possible, on another Wi-Fi network. A problem that follows one device points more strongly toward its adapter, software or settings than a dead zone. For a stationary device with a network port, Ethernet can provide a more reliable connection to that device without changing Wi-Fi performance elsewhere.

Choose equipment only for the problem you have
If placement changes and diagnosis leave a persistent coverage gap, match the equipment to the affected area and connection path. A stable wired connection to one endpoint, a targeted extension and multi-room coverage solve different problems.
| Option | Best fit | Important limits |
|---|---|---|
| Ethernet cable | A stationary device with a network port, where a cable run is practical. | Improves that wired endpoint; it does not extend Wi-Fi to other rooms. Ofcom describes wired networking as usually faster and more reliable than Wi-Fi. |
| Wi-Fi extender | A targeted coverage problem when moving the router or device is impractical. | It needs a usable connection from its own position to the existing network. No particular extender model or performance level is established here. |
| Mesh Wi-Fi | Persistent weak coverage across multiple rooms or floors after placement fixes. | Points need a good link to the rest of the network; putting one in the dead spot may leave it with a poor connection to relay. |
| Router replacement | An older router or recurring disconnections may make an upgrade worth considering. | Confirm compatibility with your ISP equipment and the needs of your home. No specific model or Wi-Fi generation is recommended here. |
Ofcom describes mesh systems as multiple units that connect with the existing router to provide Wi-Fi coverage around the home. For Google Wifi and Nest Wifi specifically, Google advises placing a point partway toward the weak area in an open location, within a suitable distance of another point; run a mesh test and adjust placement. Those instructions are product-specific, not a guarantee for every mesh brand. See Google’s placement instructions. In any system, test placement and move a point if it does not retain a good upstream link.

When to contact your provider
Escalate to your broadband provider when multiple devices lose internet access together, router or ONT indicators suggest a service fault, or interruptions continue even when a wired device is affected. Share your interruption log and the results of repeated tests, including whether a wired connection also failed. If the provider confirms the broadband service is stable but the trouble remains limited to particular rooms, return to Wi-Fi placement, interference and coverage rather than treating it as a line fault.
