Modem Checklist: Turn Off Band Steering, Split 2.4 & 5 GHz, and Pick a Better Channel

Short answer: if a device keeps dropping, or won’t stay on the band it needs, the fix is usually in your modem’s settings — not a new plan. This checklist walks you through it, one change at a time, and tells you how to undo it if it doesn’t help.

This checklist goes with our guide Wi-Fi Feels Simple Until It Doesn’t: The Stumbling Blocks That Stop Your Wi-Fi Working for You — start there if you’re not sure what’s causing the trouble.

Please read this first: every modem lays out its menus differently, and providers rename and move settings with firmware updates — so this guide tells you what to look for and where it usually lives, rather than exact clicks. The setting might be called band steering, Smart Connect, Whole Home Wi-Fi, or just one combined network name. If your screen doesn’t match, search your modem’s model name plus “separate bands.”

Before you start

Work through this checklist in order, and change one thing at a time. That way, if something gets worse, you know what to undo.

• Take a photo of your current Wi-Fi settings. Before you change anything, photograph the network name, password, and any band or channel settings you can see. That’s your undo button.
• Use a device already connected to your Wi-Fi — a laptop or phone — and stay near the modem while you work.
• Find your modem’s login details. They’re usually on a sticker on the modem itself: the address to type into a browser (often 192.168.0.1, 192.168.1.1, or 192.168.2.1), plus an admin username and password. Don’t confuse these with your Wi-Fi password — the admin login gets you into the settings, the Wi-Fi password gets devices onto the network.
• Don’t touch anything you don’t recognise. If a setting isn’t named in this guide, leave it alone. Changing the wrong thing can take your internet down, and that’s a much longer evening.
• Expect a short dropout. Saving Wi-Fi changes usually disconnects every wireless device for a minute or so while the modem applies them. That’s normal. Wired devices stay connected.

Part 1: Turn off band steering and split your bands

Band steering is the feature that puts both bands under one network name and moves each device to the band it thinks is best. When it gets it wrong, a device lands on a weak 5 GHz signal it can’t hold, or gets stuck on crowded 2.4 GHz, and drops again and again. Splitting the bands gives you two network names, so you can choose.

1. Log into your modem. Open a browser on a connected device and type the address from the modem’s sticker into the address bar. Sign in with the admin details from the sticker.
2. Find the Wi-Fi or Wireless settings. Look for a section called Wireless, Wi-Fi, Manage My Wi-Fi, or Advanced Wi-Fi.
3. Look for the combining feature. It may be labelled Band Steering, Smart Connect, Whole Home Wi-Fi, “Let the hub optimise the Wi-Fi,” or “Keep a common network name for both bands.” Turn it off, or uncheck the common-name box.
4. Give each band its own name. Once split, you’ll see separate settings for 2.4 GHz and 5 GHz. A clear naming habit helps everyone in the house: keep your usual name for 2.4 GHz, and add something like -5G to the 5 GHz name (for example, MyWiFi and MyWiFi-5G). You can keep the same password for both.
5. Save, and let the modem restart if it asks to. Your devices will disconnect briefly, then the two new network names will appear in your Wi-Fi list.
6. Reconnect the troublesome device to the band it needs. Far from the router, or a device that only supports 2.4 GHz? Connect it to the 2.4 GHz name. Close to the router and streaming? Connect it to the 5 GHz name. If it still shows the old single name, forget that network on the device and reconnect fresh.

Where to look, modem by modem

• Most routers (TP-Link, ASUS, Netgear, and others): Wireless settings, then look for Smart Connect or Band Steering and turn it off. On some ASUS firmware it’s under Wireless, then General, then Enable Smart Connect.
• Bell Home Hub (3000 / 4000): log in at 192.168.2.1, go to Manage My Wi-Fi, turn off Whole Home Wi-Fi, then open Advanced Settings and uncheck “Keep a common network name.” One trade-off to know: Bell Wi-Fi pods rely on Whole Home Wi-Fi, so they may not work while it’s off.
• Rogers Ignite / Xfinity gateway: splitting bands is usually done in the Rogers Xfinity app, under Wi-Fi details and Wi-Fi settings, by giving the 2.4 GHz and 5 GHz bands different names. On older Rogers Hitron modems, log in at 192.168.0.1 and look under Manage Wireless.
• Telus, Cogeco, Videotron, Shaw, or a modem not listed here: use the generic steps above, then search your exact modem model plus “separate bands” — the setting is almost always there, just under that provider’s name for it. If the setting seems locked, your provider’s app may be the only place it lives.

If you can’t find the setting at all, stop here and skip to “If you get stuck” below — don’t guess at other menus.

Part 2: Set up a dedicated 2.4 GHz (guest) connection

If splitting the bands feels like too much change for the whole house, or your modem won’t split cleanly, a guest network is the gentler version of the same fix: one extra network, just on 2.4 GHz, for the device that keeps getting steered wrong.

1. In your modem’s Wi-Fi settings, look for Guest Network (sometimes under Wireless, then Guest, or Advanced).
2. Turn the guest network on, and set it to 2.4 GHz only if that choice is offered.
3. Give it a clear name — something like MyWiFi-2.4 — and a password you can type easily on the device.
4. Save, then connect the troublesome device to that guest network only. Leave everything else on your main network.
5. Test it for a day. If the device stays connected, you’ve found your fix, and you didn’t have to rename anything for the rest of the house.

Note: some guest networks are set to isolate devices from each other, which can block things like casting to a TV. If casting stops working on that device, that’s why — move it back to the main 2.4 GHz network from Part 1 instead.

Part 3: Pick a better Wi-Fi channel

Channels are the lanes inside each band. If your neighbours are all in your lane, everyone slows down — even with full signal bars. This part takes about ten minutes, and it’s worth doing after Parts 1 and 2, not instead of them.

1. Scan first. On Android, a free Wi-Fi analyzer app (WiFi Analyzer is a common one) shows a graph of nearby networks and their channels. On iPhone, the AirPort Utility app can show channel use if you turn on Wi-Fi scanning in its settings. You’re looking for the quietest lane, not just an empty-looking number.
2. On 2.4 GHz, only pick 1, 6, or 11. These are the only channels that don’t overlap each other. Picking a number in between — like 3 or 8 — actually causes more interference, even if it looks empty on the graph. Choose whichever of 1, 6, and 11 has the fewest and weakest neighbours.
3. On 5 GHz, leave it on Auto unless you live in a dense building. There are many more non-overlapping channels on 5 GHz, so Auto usually does fine. In a busy apartment, pick the quietest block your analyzer shows — often in the 36–48 or 149–161 ranges.
4. Change it in your modem. Back in Wireless settings, find the Channel setting for the band you’re changing — it’s usually set to Auto. Change it to your chosen channel, leave the channel width at 20 MHz on 2.4 GHz unless you know why you’d change it, and save.
5. Test in the same spot, before and after. Run a speed test or just use the troublesome device in its usual room, and compare with how it was before. If it’s worse, switch back to Auto — that’s what your photo from “Before you start” is for.
6. Recheck every few months. Neighbours get new routers, and the quiet lane fills up. A quick rescan now and then keeps this fix working.

If you get stuck, or want to undo it

• A device won’t connect after a change? Forget the network on that device and reconnect with the right password. If it still won’t connect, reboot the modem and try once more.
• Everything got worse? Put the settings back exactly as your photo showed them, save, and reboot the modem. Then stop — that’s what the photo was for.
• Can’t log into the modem? Check the sticker again, and make sure you’re connected to your home Wi-Fi (not mobile data) when you try. If the admin password was changed and forgotten, that’s a provider-support job — a factory reset wipes everything, so don’t do that on a guess.
• The setting isn’t there, or it’s greyed out? Some provider modems lock it down. That’s not a failure on your part — it’s the modem. The provider’s app, or a separate router of your own, may be the way around it.

The quick checklist (print this bit)

• Photo taken of current Wi-Fi settings
• Logged into the modem (address and admin details from the sticker)
• Band steering / Smart Connect / common network name turned off
• Bands renamed clearly (for example, MyWiFi and MyWiFi-5G)
• Troublesome device connected to the right band, or to a dedicated 2.4 GHz guest network
• 2.4 GHz channel set to the quietest of 1, 6, or 11 (5 GHz left on Auto unless you’re in a dense building)
• Tested in the usual room, and settings photo kept in case you need to undo it
