Why Is My Phone Charging Slowly?
Isolate the charger, cable, phone and wireless setup, then check whether heat, use or a battery setting is intentionally limiting the rate.

My Wi-Fi is slow in one room
The 30-Second Answer
Most slow Wi-Fi isn't caused by your internet provider. It's usually thick walls, metal HVAC ducts, or a router tucked away in a cabinet or floor corner blocking the high-speed radio waves.
Try This First
- Move your router out into the open and elevate it 3–5 feet off the floor (never inside a closed TV cabinet).
- Check if your device is connected to the 5 GHz Wi-Fi band instead of 2.4 GHz when in the same room.
- Restart both your internet modem and Wi-Fi router by unplugging them for 30 seconds.
Why this happens (Radio attenuation & frequency)For enthusiasts & engineers
Modern 5 GHz and 6 GHz Wi-Fi signals offer high bandwidth but have shorter wavelengths that absorb heavily when passing through drywall, plaster, brick, and metal furnace ducting. A signal dropping from -50 dBm to -75 dBm results in automatic protocol fallback and high packet loss.
Associated Engineering Standards:
- 5 GHz / 6 GHz signal attenuation through drywall: ~3 dB to 10 dB loss
- Wi-Fi 6 (802.11ax) OFDMA channel contention
- Ethernet standard: TIA-568-C.2 Cat6 pure copper (10 Gbps up to 55m)

Compatibility Breakdown
Your Dock & Dual Screen Checklist
Educational guidance based on hardware standards, not a compatibility guarantee. CANOD has not tested your exact hardware.
MacBook Air Dual-Screen Limitation
Base Apple Silicon chips (M1, M2, and M3 MacBook Air) natively support only ONE external display. If you plug into a standard USB-C or Thunderbolt dock, both monitors will show the exact same mirrored picture. To get two independent extended screens, you must choose a dock with DisplayLink USB-graphics software.
Apple: external-display limits on MacBook ProDisplay Resolution & Refresh Rates
Setup goal: two independent external displays at Not sure yet. Ensure the dock documentation explicitly states it can run all connected screens simultaneously at 60 Hz rather than dropping down to 30 Hz.
VESA: DisplayPort over USB-C FAQDisplayLink Screen Recording Permission
If you use a DisplayLink dock to run dual screens on a Mac, macOS requires 'Screen Recording' permission in System Settings. Verify if your corporate IT policy allows this on managed work laptops.
DisplayLink: macOS Screen Recording permission DisplayLink protected-video limitationsHost Power Delivery Sufficiency
Your laptop needs up to 65 W. Make sure the dock states power delivery TO THE LAPTOP (host), not just the size of the dock's power brick.
Microsoft: USB-C connection and charging problemsCanadian Purchase & Return Protection
Before unboxing a dock in Canada, verify return shipping terms and whether opened electronics carry a restocking fee, in case your laptop model has an unexpected compatibility quirk.
Advanced Technical Specifications (2)
- Thunderbolt / USB4 Connection: Your laptop has Thunderbolt 3, 4 or 5. This provides the highest video bandwidth (40 Gbps), allowing dual 4K monitors on compatible docks.
- Apple Silicon Display Ceilings: MacBook Pro with M-Pro chips supports up to two displays; M-Max chips support up to four displays. A dock cannot bypass Apple's native hardware maximum.

Buy Safe in Canada
Before connecting it, charging it or bringing it home, check whether it is suitable for use in Canada.
CANOD helps you identify the specifications, approval information and warning signs worth checking before buying electrical and connected products.
Identify the approval information on the exact mains-powered product. Compare it with the official reference, not just a seller's claim.
Ontario ESA: recognized approval marks Read this buying considerationRead the input label and instructions. Confirm the stated supply voltage and frequency suit the intended location; plug shape is not enough.
Health Canada: electrical product safety Read this buying considerationCompare the charger output with the exact device's requirements. Ask the manufacturer about any mismatch or missing information.
Health Canada: lithium-ion battery safety Read this buying considerationCheck the charging profiles supported by the charger and device, including any sharing of power between ports.
USB-IF: USB Power Delivery Read this buying considerationA matching USB-C connector does not tell you the cable's power or data capability. Check the whole connection.

How we reach a useful answer
Good products earn their place in your day.
We start with a simple question: what does this make easier?
Our current guides are research-based, not hands-on product tests. We make that distinction clear.
The CANOD editorial method
Problem
Define the job: connect a workspace, protect important files or carry a practical kit. A useful answer starts with the need, not the product.
Research
We use original writing and link technical claims to official documentation, manufacturer specifications or other relevant primary sources.
Verify compatibility
Look at the exact device, software, cables and intended setup. Flag what remains unknown instead of turning assumptions into guarantees.
Calculate total cost
Include required accessories, ongoing costs, Canadian availability, delivery and return conditions. Compare the total, not just a headline price.
Explain the decision
Explain who a solution suits, its limitations and when it may not be needed. Suitability comes before commission potential; commercial relationships will be clearly identified.
