Guided check
0/4 checkedMatch the symptom, then work through the safe checks.
1. What best matches what you observe?
2. Complete only the checks that are safe for you.
4 user-level checks are available in this guide.Stop immediately if any warning condition applies.
Show stop conditions
- Running cable would require unsafe drilling or electrical work
- Powerline adapters would cross unknown electrical systems
Likely causes
- The room has weak signal or obstructed line of sight
- The device is connected to a distant access point or band
- Local interference affects the selected channel
- The client device has a weaker adapter or antenna
Quick checks, in order
Run the same test near the router and in the room
Use the same device and test method.
Check which access point and band are used
A device can remain attached to a distant mesh node.
Move the router into the open and higher
Avoid cabinets, floors, TVs, and metal objects.
Consider a wired access point or properly placed mesh node
Do not place a repeater where the original signal is already unusable.
How does performance change by location?
Fast near router, slow in room
Coverage or interference is the main issue.
Slow everywhere
The internet service, router load, or main equipment may be limiting speed.
Only one device is slow
Check its band, adapter, power saving, and background activity.
Stop and get qualified help when
Do not continue troubleshooting if any of these apply:
- Running cable would require unsafe drilling or electrical work
- Powerline adapters would cross unknown electrical systems
Frequently asked questions
Will a faster internet plan fix one dead room?
No. The bottleneck is the local Wi-Fi path, not necessarily the provider speed.
Where should a mesh node go?
Place it where it still receives a strong link from the main router, not inside the dead zone.
