Hello, I’d like to refer back to my original post, where I initially assumed that my WAN settings were incorrect. For a while, the suggested solutions worked quite well. However, I’m running into problems again, and I’ve discovered some new information that might point to the real issue.
The Wi-Fi infrastructure where my router is connected consists of multiple APs and SSIDs spread across a large building. For some reason, the AP that my RUT240 connects to changes its channel every hour. I assumed this might be due to client movement within the building—so that the AP with the best signal takes over the channel for smoother roaming.
The problem is that my RUT240 is fixed in place. Each time the AP changes its channel, the Wi-Fi connection drops, the 4G failover kicks in, then Wi-Fi reconnects on the new channel. This causes all connections to reset, and after about 60 seconds the main WAN switches back to Wi-Fi again.
This seems like a major issue. Is there any way to handle dynamic channel switching without losing the connection for about a minute? Any ideas?
Interesting situation… I don’t believe we have any direct solution for this, besides maybe using a custom script, not even sure about the logic that would go into it, but something should be possible.
For a workaround, we’ll have to come back to what I’ve suggested previously, which is… increasing the values under the failover settings so the pings keep running for 1 minute straight before proceeding to failover, that would come to a number in the hundreds, I believe..
Other than that, it comes down to your access point itself, how it’s configured, how it behaves, not much I could suggest concerning that.
Thanks for your quick reply, as always! =) I have two ideas:
I’m trying to convince the local admin to set up a separate single-channel SSID on the nearest AP, where the RUT would be the only client.
In the meantime, there are five APs broadcasting the same SSID on channels 1 and 6, with signal quality ranging from 21% to 82%. Would it make sense to add another Failover AP with the same SSID but on a different channel/BSSID?
I believe it always comes down to testing, but it does sound like a good thing to add to avoid any issues, just in regards to the SSID, if you don’t have a mesh configuration (I don’t see a mention of this being the case) I don’t think you’d need to have the same SSID as it’d be easy to mix up, up to you, of course.
Together with the local admin, I discovered something else absurd: In the WiFi scan, the RUT modem is reading the AP’s MAC address incorrectly. Instead of C0:C7:0A:1C:C9:B0, it’s reading C0:C7:0A:5C:C9:B7. I don’t understand it. Is the modem simply junk?
Both of these MACs return a device that is from the same company, Ruckus Wireless, therefore, I think that what you’re seeing is just a different access point, since you did mention having more than 1. Could you confirm or deny this?
No, admin says the MAC that was read by the RUT does not exist. Since I manually put in the “correct” MAC the Wifi Failover does not work anymore at all I think I’ll give up on this ….
If you haven’t yet given up, I could try asking our R&D to investigate this issue, but for that, I would need a troubleshooting file from when the issue was present. I’d also need a topology so it’s clear how everything is connected, and to what.
