TP-Link XE75 PRO 5GHZ Not Working! What to Do

Nothing’s more frustrating than your shiny new TP-Link TP-Link XE75 PRO 5GHZ Not Working. You’ve got devices that support it, the router lights are fine, but when you try to connect? Nothing. 2.4GHz might work, sure, but 5GHz is where the speed lives.

This isn’t some mystical “router curse.” Usually, it’s a little setting, firmware hiccup, or interference thing messing with you. In this guide, we’re going to break down what’s actually going on with the XE75 Pro 5GHz, and more importantly, how to get it back online with the help of TP-link Deco setup interface.

Why TP-Link XE75 PRO 5GHZ Not Working?

• Channel interference: 5GHz is fast but also picky. If your neighbors’ Wi-Fi is on the same channel—or too many devices are hopping around—your XE75 can decide to just… not. work. Go into the router settings, switch the 5GHz channel to something less crowded. Sometimes “Auto” works, sometimes it doesn’t. Trial and error.
• Device compatibility: Not all devices play nice with 5GHz, especially older laptops or phones. Some only do 802.11ac, some need 802.11ax (Wi-Fi 6). Check if your device actually supports the 5GHz standard your router is broadcasting.
• Distance weaken the signals: 5GHz doesn’t travel through walls well. If your device is too far from the XE75, it might not even see the network. Move closer and see if it shows up. If it works nearby but drops when you walk away, it’s just physics.
• Firmware drama: TP-Link routers love a firmware update, but sometimes updates glitch. Make sure your XE75 is running the latest firmware. And if the problem started right after an update… yeah, roll back if you can or wait for the next patch.
• Router settings gone rogue: Sometimes settings just… break. Guest network, QoS, MAC filtering—all can accidentally block 5GHz connections. Go through each setting, double-check, maybe even reset the router and set it up again. Painful, but often fixes it.
• Overheating or hardware issues: If it’s really random—works sometimes, doesn’t other times—it could be a hardware thing. Routers get hot. Let it breathe. Unplug for a minute. Or, worst case, it’s a dud and needs replacement.

How to Resolve TP-Link XE75 PRO 5GHZ Not Working issue?

1.Check the basics first.

Make sure the router isn’t in some weird spot. 5GHz is picky. Walls, microwaves, cordless phones—these things kill it fast. Move it higher up, away from heavy electronics.

2. Reboot everything.

Router first. Wait 2–3 minutes. Then your device. It sounds dumb, but a fresh start clears some weird handshake issues between the router and device.

3. Firmware update.

Go to the TP-Link site or the app. Make sure your XE75 PRO is on the latest firmware. They push updates for a reason—5GHz fixes are common. Apply it, reboot, check again.

4. SSID and channel check.

Sometimes the 5GHz band is on auto-channel, and your house neighbors are jamming it. Open the router settings (usually 192.168.0.1 or via the TP-Link app), go to 5GHz settings, try setting a fixed channel like 36, 40, or 44. Forget the network on your device, reconnect fresh.

5. Band steering mess.

XE75 PRO has band steering, which is supposed to auto-move devices between 2.4 and 5GHz. In reality, it messes things up. Disable band steering, connect manually to 5GHz, see if it sticks. If it works, leave band steering off.

6. Advanced Wi-Fi settings.

Sometimes 5GHz is set to “Auto” for width (20/40/80 MHz). Manually force it to 80 MHz if your devices support it. Also check WPA3 vs WPA2—older devices hate WPA3. Switch to WPA2/WPA3 mixed if needed.

7. Device-side quirks.

Some laptops or phones just hate certain 5GHz channels. If nothing else works, test with a different device. If it works there, the problem is your original device, not the router. Update its Wi-Fi drivers or firmware.

8. Last resort: factory reset.

if you are seeing the Deco red light again and again, you should reset the device. Hold the reset button 10 seconds, set it up fresh. Pain in the butt, but cleaner than chasing random settings forever.

The Conclusion

TP-Link XE75 PRO 5GHZ Not Working almost fixable. If you’ve done all this and 5GHz still refuses to play nice, hit TP-Link support. They’re slow sometimes, but at least you’ll know it’s not on you.
