First of all, I apologize that I write a long story here. It's been such a headache dealing with troubleshooting.

I contacted an agent on live chat yesterday.
This agent was very thorough. He even explained to me a lot how wifi and radio works.
As any of my devices could find 5Ghz on wifi list, He made some changes on the modem and he went over with me resetting it.


What can I say... Wi-Fi is complicated.  It normally should "just work" but when it doesn't, the troubleshooting process can be extremely frustrating, especially when devices refuse to connect or you don't get the speeds that you expect, or when the Wi-Fi throughput drops for no apparent reason.

 

I think he disabled the Band steering and separated 2.4Ghz and 5Ghz bands.
Finally my phone and tablet can connect to 5Ghz, and their WiFi speed is at 500Mbps, which is equibalant t my internet plan, finally. With 2.4Ghz, speed remains around 30-80Mbps.
I tested my laptop with 5Ghz. Wifi speed was around 140Mbps.

I'm pretty happy that I finally got the good speed. Although my question is...

Why the modem's band steering is not working with my most recent devices ??

is it ideal to keep the band steering disabled ?


Band Steering is not something that you absolutely must have enabled.  It can be a convenience -- you can have a single SSID for both the 2.4 and 5GHz networks and the 5GHz-capable devices will "automatically" connect to that band which (normally) should provide higher throughput and less interference.

 

Wi-Fi devices discover networks in one of two ways: active and passive scans.  Some wireless clients only perform passive scans; they sweep each channel looking for beacon frames, which are sent by Access Points to advertise their Wi-Fi networks, and either connect to known networks or allow the user to select the network that they wish to join.  With active scanning, the wireless client sends "probe requests" on each channel looking for a response from the Access Point for networks that they wish to advertise.

 

When Band Steering is enabled, the Access Points do not actively advertise their networks.  If the AP hears a probe request on the 2.4 GHz band, it may not respond to that request unless it has not heard a probe request on the 5GHz band in the last 60 seconds.  (On some AP's, this timeout is configurable.  Implementations might also vary.)  Although this approach works great most of the time, Band Steering can cause problems for some devices.  If a wireless client can only discover Wi-Fi networks through passive scans, it won't be able to connect to an AP with Band Steering enabled.  If a wireless client "gives up" trying to connect if it does not get a response to a probe request on the 2.4 GHz band within 60 seconds, then it will never be able to connect to that AP with Band Steering enabled.  (Those are just some of the scenarios.)  Suffice it to say, the wireless client and the Band Steering implementations need to be compatible with each... or offer users the ability to fine-tune settings to make them compatible.

 

Please forgive me for over-simplifying the above explanations but, like I said before, Wi-Fi is complicated.  If everything works for you with Band Steering enabled, great.  If it doesn't, disable it.  You'll miss out on the benefits that Band Steering offers but it's far more important that all of your devices are able to connect.

HP laptop and Motorola phones cannot find network

 

I have Ignite and if connected to the router by network cable there is no problem, but neither an HP laptop nor two phones can reliably find or connect to the network wirelessly

Re: Band Steering on XB6 Modem Causing Issues for 2.4 GHz Devices

Season’s Greetings,

Rogers pods deactivate 3rd party wifi extender. I have the Rogers ignite Gateway modem/router and 3 Rogers pods on each floor of my house.

I also have a Netgear wifi extender that has the dual band feature that allows me to manually connect to either the 2.4 or 5G band.

Here’s my issue; I have certain devices around the house that require a connection to the 2.4G band (weather station, smart plugs etc.)

Everything was good until a few days ago when my weather station and smart plugs stopped working as they wouldn’t connect to the network, I’m convinced that this was caused by the addition of the 3 Rogers pods.

My understanding is that the pods connect to the modem and they rely on distance/strength to amplify the signal thus creating a “mesh network” and automatically change the band based on this distance.

However, I can still see the dual bands from the Netgear extender on my network, but when I select 2.4G to reconnect these devices they won’t connect. My only reason for keeping this extender is to support these 2.4G devices.

I know there is a way to split the bands from the Gateway modem/router via the ignite wifi hub but since installing the pods this feature is disabled on the app.

Is there some sort of work around to keep my pods connected AND enable my wifi extender?

Any advice/tips would be greatly appreciated.

Thanks!

Re: Band Steering on XB6 Modem Causing Issues for 2.4 GHz Devices

The extender, has 2.4 and 5 on it?
Its almost like its preferring the 5 on it, and then not extending the 2.4?? 

If your not really needing the range per say on the extender itself, are you able to disable the 5 on the extender?  Then it should only do the 2.4.


Its interesting on how/what IoT smart devices work/not work with the band steering on.
I have..  probably about 15 devices?  I know a good 2/3 of them say they are 2.4 only.
None of them have had any issues so far with band steering and connecting.
Even when i switched the pods (from the original EERO to the current ones)

Re: Band Steering on XB6 Modem Causing Issues for 2.4 GHz Devices

Hi

 

Having an issue with the 2.4 band on my XB6 modem - basically it has disappeared. After all the various restart/reset/changing 2.4 SSID names solutions were exhausted - a technician visit was arranged.

 

The technician adamantly insists that you can't have different names for 2.4 and 5 ghz bands! "I have the same modem at home, and you cannot do it!" is his reasoning!

 

What sort of technicians do you have?

Re: Band Steering on XB6 Modem Causing Issues for 2.4 GHz Devices

It seems my ignite router is set up to automatically manage the 5Ghz and 2.4Ghz channel allocation.  The router gateway management portal will not allow me to make any changes such as renaming the 2.4Ghz channel or broadcasting the SSID for the 2.4Ghz channel.  Can anyone help.  I would like the router to broadcast both channels so that I can assign devices manually.  Cannot set up my smart devices otherwise.  Help?

Re: Band Steering on XB6 Modem Causing Issues for 2.4 GHz Devices

@tbuehl I know that your post was moved to this thread, so the question is whether or not you have an XB6 modem with the Ignite TV service.  If so, call tech support and ask the tech support rep to disable Band Steering and Auto Channel assignment.  After Band Steering has been disabled, you should be able to rename one of the wifi networks in order to separate the 2.4 and 5 Ghz networks. 

 

The tech support rep might tell you that this can't be done, however, there was a recent post from another customer who had tech support disable Band Steering and Auto Channel.  So, it can be done, just a question of finding the right tech support rep who knows how it can be done.  Most likely its a hidden enable/disable function in their modem option menus, just have to find it. 

 

If you have a Hitron CODA-4582 modem, log into the modem and:

 

1.  navigate to the Wireless .... Advanced tab.  Disable the Band Steering in both the 2.4G and 5G tabs and save the setting.  

2.  navigate to the Basic Settings and 2.4G and 5G tabs and select an appropriate channel or channel groups.  That will disable the Auto channel setting.  Save the changes on each tab.  

3.  Rename one of the networks, either the 2.4 Ghz or 5 Ghz as desired.  Save the changes.  

4.  Reboot the modem, using the ADVANCED .... DEVICE RESET .... Reboot function.

If you have Ignite WiFi Pods installed (or even associated with your account) then I'm almost positive that neither you nor tech support can disable band steering or auto channel selection.

 

If you do not have Pods installed, then I believe you can disable band steering using the Ignite WiFi app.  (When you edit the network name, there should be an option, "Use different names and passwords for 2.4GHz and 5GHz WiFi".  Having different names configured will disable band steering.)
