LAN fast, WiFi slow
Your fibre line is probably okay. Focus on router placement, WiFi band, device limits and mesh coverage.
If your Maxis Fibre speed is good near the router or on LAN cable, but slow in bedrooms, upstairs or the kitchen, the issue is usually your WiFi setup. Try these checks before upgrading your fibre plan.
Fibre speed and WiFi speed are different. LAN cable gives the most stable test. WiFi can be affected by distance, walls, router placement, old devices, interference and number of connected devices.
Your fibre line is probably okay. Focus on router placement, WiFi band, device limits and mesh coverage.
Then it may be line, modem, account, outage or device issue. Report or check with support before buying mesh.
That is usually coverage. Moving the router or adding mesh is more useful than upgrading speed.
Before changing plan, test the connection properly. This prevents you from paying more for a faster plan when the real issue is only room coverage.
Connect a laptop directly to the router using LAN cable and run a speed test. Wired speed is the cleanest test because it avoids WiFi walls and interference.
Stand near the router and test WiFi. If near-router WiFi is good but bedroom WiFi is poor, the issue is coverage or placement.
Many slow WiFi cases happen because the device connects to the wrong band. The “best” band depends on distance and walls.
Better reach through walls, but usually lower speed and more interference from neighbours or household devices. Good for smart devices and far rooms.
Better for video calls, streaming and gaming when you are close enough to the router. Speed drops faster when passing through walls.
Open area, higher position, central part of the home, away from metal objects and not blocked by furniture.
Inside cabinet, behind TV, on the floor, in a house corner, behind thick walls or beside electronics that cause interference.
Mesh WiFi creates wider coverage using extra WiFi points. It is useful when your fibre plan is already enough, but signal cannot reach the whole house.
Weak upstairs signal is common when the router is installed near the front or downstairs.
Back rooms, kitchen and master bedroom may not get stable WiFi from one router.
Maxis has Max WiFi add-ons from RM19/month, with higher tiers offering more mesh coverage and Always On WiFi backup.
If LAN speed is normal but your household constantly maxes out the plan with 4K streaming, gaming, downloads and WFH at the same time, a higher plan may help.
If the router area is fast but bedroom WiFi is slow, upgrading speed will not fix wall, distance or coverage problems. Fix WiFi setup first.
Because LAN cable avoids WiFi interference, walls and distance. WiFi speed depends on router placement, WiFi band, connected devices, device capability and your home layout.
Not immediately. If LAN is fast but WiFi is slow, fix router placement, WiFi band or mesh coverage first. A higher plan will not fix weak signal in a room.
WiFi 6 can help homes with newer devices and more simultaneous connections. It works best when your device also supports WiFi 6 and the router is placed properly.
Yes, if your home has weak WiFi in certain rooms, double-storey layout, thick walls or far bedrooms. Mesh is mainly for coverage, not for changing your base fibre speed.
Maxis 5G Home WiFi is a separate wireless broadband product, not a WiFi extender. If your fibre is available but room WiFi is weak, mesh is usually the better fix.
If all devices are slow even near the router and LAN speed shows you need more bandwidth, consider a faster plan. If only certain rooms are slow, consider router placement or mesh.
Send your address and tell us which room is slow. We check fibre availability, suitable plan and whether router placement, Max WiFi or mesh is the better solution.
🔍 Check My Coverage & WiFi SetupIf your Maxis fibre line tests fast but your wifi speed at home feels slow, the problem is almost never the fibre itself. It is usually router placement, an overloaded 2.4GHz band, too many connected devices, or an old router that cannot handle your plan's full speed. Before switching ISPs or paying for a technician visit, run through this checklist first.
Speed tests measure the connection to your router, not the wifi signal reaching your device. Walls, distance, and interference from neighbouring wifi networks weaken the actual wifi signal even when the fibre line itself delivers full speed. Switching to the 5GHz band or moving closer to the router usually solves this instantly.
If you are on Maxis Home Fibre 300Mbps at RM99/month with a postpaid line and still get slow wifi, upgrading to 500Mbps at RM139 or 1Gbps at RM159 will not fix a placement or router problem. Try repositioning the router centrally and away from walls first; only upgrade if multiple devices are streaming or gaming simultaneously and genuinely need more bandwidth.
Maxis 5G Home Wifi plans at RM69, RM79, or RM109 come with a free router and free TNG credit, and can be a good alternative if fibre installation isn't possible at your address. However, 5G home wifi depends on cellular signal strength at your location, so it may not solve slow-wifi issues if your area has weak 5G coverage.
New sign-ups for Maxis Home Fibre with a postpaid line get free 3 months or a device for RM1/month, valid until 15 July 2026, and plans without a Maxis line start from RM89. This is useful if you're due for a router refresh anyway, since newer routers handle wifi distribution better, but the promo itself doesn't directly fix an existing slow-wifi setup.
