WiFi Channel selection

I tried resurrecting an old thread about WiFi connection preferences weeks ago and received no hits.

I use Stick+ in most of my bedrooms.  I've got VERY GOOD WiFi coverage everywhere on multiple APs and multiple discrete channels.  I'm in an area where I have pretty much the entire spectrum to myself for both 2.4 and 5GHz.  I use the SAME SSID for all networks on ALL APs and am not interested in debating this nor making changes/additions to SSIDs.

The ROKUs apparently have a very simple connection selection algorithm and no method I can find to specify a preferred band to use.  More often than not the Stick+ seems to select the first signal it can connect to in channel order (1 to 11 on the 2.4GHz and then again ascending on the 5GHz).  I often have problems in 2 rooms and find the Stick+ connected to APs I'd never intentionally pick and playback errors are high.  Also this manifests itself in remote connection issues as well.  My Stick+ powers on/off with the TV (TV USB power).  I'm also not open to changing that.

PLEASE look into the selection algorithm and PLEASE add a setup value for preferred band (2.4GHz vs 5GHz).  This is pretty standard stuff for clients these days.

Thanks in advance.

Re: WiFi Channel selection

Clients can be pretty clingy with AP's, once it chooses one it's generally reluctant to choose another even if it's stronger, I'd suggest resetting the network on the problem Rokus and reconnecting.

You are correct and that's why most modern adapters have a roaming aggressiveness setting to help it determine at what signal level it should seek a different connection. 

If you notice I said I have the ROKU power down/up with the TV.  This isn't a one off occurrence.  It's a programmatic pattern.   It would be great to have that added as well as a preferred band setting.

Right now the ROKU isn't even selecting the best connection at startup, simply the first.

Right, but just turning off the Roku won't remove the current AP from the Roku, the network connection on the Roku needs to be reset for that to happen, it may still connect to the AP you don't want it to because of the other circumstances you've pointed out, but removing it with a reset will at least give it a chance.

That makes absolutely no sense that the ROKU would remember a specific connection across a power cycle.  SSID yes but not a specific association.  If that in fact is the case then it's yet another bug that needs to be fixed.

Networking can behave oddly sometimes, starting with a clean slate would only take a minute, worth a try.

I know from experience a Roku will auto connect to the same SSID even if it isn't the same hardware. But as to which band it selects, I can't say. Windows does the same thing, as does my iPhone. They always reconnect to the same SSID as previously used.  That's one of several reasons I at use different SSIDs on 2.4 and 5 GHz, so I can at least choose which band I'm using. I prefer completely different SSIDs on my WAPs so I absolutely know which one I'm using. I know you said you have reasons for not doing so. Just adding my $0.02. Smiley Happy

Yes, remembering and using the same SSID is what it is supposed to do.  As to assigning separate SSIDs, I'm not going to entertain that nor get into a discussion about it.  All I'll say is best practices is to use a single SSID across your APs.  An SSID is for a group of features/functions/users (Service Set).  Using separate SSIDs to steer frequency use is a hack to overcome a poorly designed client and/or network.

Re: WiFi Channel selection

I saw your first post. All I'm saying is that there are many, many devices that work exactly like the Roku does. It remembers and reconnects to the same SSID. Hopefully it selects the best band (5 GHz usually). I don't consider it a "hack" to use different SSID names, at least for the two bands. In the medical center network I designed and managed, I uses the same SSID on all WAPs, so you won't get any argument from me on that. But they were all 2.4 GHz. At that time, I don't think 5 GHz was even available, or if it was it was priced beyond my budget at the time. I didn't intend to try to change your mind or get into a major discussion about it. Only pointed out what works for myself. I strive to simply provide information that has worked for me. It may or may not be the best suggestion for someone else. Have fun.  Smiley Very Happy

Re: WiFi Channel selection

If your router allows the txpower to be set you could also try setting your 5ghz band a little higher than 2.4 to help band steering.
